Finally finished cutting out my new precision bird. It is bigger than my airframes from last year in several dimensions, including weight... Not a problem though, as the wingloading is actually lower than my birds from last year.

All up expected finished weight will be around 130grams (about 4.5ozs)based on loading all the parts and componentry on the scale and adding a bit for the inevitable 'unknown' weight adding stuff. I'm going for a wingloading of around 2.5-2.7ozs per square foot.

I'll likely end up building another and milling the foam out for lighter weight. Now that I have a baseline weight for the cut parts, I have something to compare against.

Should be fun.

More updates,
Pretty unhappy with the final airframe weight of 3.25 oz. Going to make some changes already. Going to reduce the wingspan and fuse length by 5" so wingspan would be 28" with a fuse length of 30". Also reducing chord of main wings to 8 1/2". Stab will stay the same. Distance between wings will be reduced by 2". Also, next version should be machine cut to help prevent me screwing stuff up. LOL

What glue are you guys using to buid these F3P planes? I used regular CA, but wasnt sure if there was something a little lighter maybe? I only tacked parts together, to save weight on glue, so I'm not sure where all of the weight came from.

Will still fly it, probably at the JR Fest if I can get my electronics and motor by then . . .

Okay guys,
Here are some updates to my design. Got the vertical fuse/horizontal fuse cut and glued. Stab is also glued on. Drag plate holes are cut, along with the "twist" braces for the fuse. Going to glue wings to fuse tomorrow, and hopefully start adding my carbon fiber to the plane tomorrow night. We shall see . . .

Inspired by Brandon Chitty's efforts last year, I decided I would decide upon my freestyle music early on and fly to it from now until the contests... I set a goal of having it completed by the end of October.

Well, yesterday while at Target picking up sippy cups for my daughter, a sound track caught my eye. I took it to the register with the sippy cups and while my daughter sipped juice and giggled at Elmo on the cups I found 2 perfect songs to fly to.

Mixed them up using Audacity this evening and it came out just right!

I also hit another major goal this weekend, but not flying related.... 2 yrs ago at the EX Games, I came down with a serious migraine headache. I got some serious headache medication from another competitor and made it through the evening. Bad news was that I passed out cold from the pain of another headache about 3 weeks later.

Doctor diagnosed me with seriously high blood pressure, cluster headaches and prescribed medication to combat it/them. He also prescribed me to lose 40lbs (I was just under 230lbs at the time and was still that weight until New Years 2006/7).

Well as of today, my blood pressure is under control, and I am now 199lbs!!!!!!!!!. I would really like to lose another 15-20lbs, but I'm pretty happy with everything so far. I lost the weight by getting back on my bicycle. Over 2000 miles this year with many rides well over 50 miles.

I was a bicycle mechanic most of my way through college, so I built myself a bada$$ new ride.... 15.2lbs ready to ride, full Dura Ace, Easton wheels, FSA Carbon Pro Cranks.

My first foamy design. Made for F3P/Freestyle contests (such as the ETOC). I have the first parts cut out:

1 Wing
2 SFG/Wing Struts
4 Aileron SFG thingamajiggers (whatever they are called
Horizontal Stab
2 Drag Plates minus the holes being cut (you can see the circles where the holes will be cut in the pic
2 Wheel Pants/Landing Skids

Whats left to cut out:
1 Wing
Vertical Fuse/Rudder
Horizontal Fuse
2 Tail flex prevention pieces
and I think that is it.

Have to wait for more foam/carbon fiber to show up sometime this week before it can be finished . . .

Setup will be:
Motor - Hacker A10 9L
ESC - Castle Creations Pheonix 10
Servos - Dymond D47 on Rudder/Elevator 1 Futaba 3154 on ailerons
RX - JR 610 UL on one, FMA Direct 5 Ch on another one
Batts - TP 350 mah and 480 mah 2s1p

This is by no means the only way to do this. Lots of people use different setups, however, this is by far the setup that has been easiest for me to make and setup.

No commercial hardware out there has every done the job well enough for me, so I make my own. The commercial hardware usually has too small of a base and you end up losing a lot of throw from flex at the base of the control horn.

My setup simply uses carbon pushrods sized to the model. Music wire z bends are fixed to the ends with heat shrink tubing. Control horns are all 1/32" ply with the hole hardened with thin CA and then re-drilled.

I always use a pushrod brace on the tail pushrods as the flex in the pushrod can rob you of accuracy and full throw.

Getting appropriate geometry is of the utmost importance as well. I don't like to drive little servos all the way to 140% as some don't handle that well. For F3P planes, I try to set it up so that 120% throw gives enough to do the maneuvers, but not any more. That way you get the most of the resolution of the radio/servos. Thats not any kind of a new thought, I borrowed it from Wayne Geffon...

I did some analysis of my foamy building last year, and I realized a pretty large portion of my time was used creating hardware. I cut my own control horns etc from plywood, and last year I ended up cutting out several dozen sets of them... For this year, I've decided that I am going to have them laser cut. Should save a bunch of time and will make the hardware more accurate. More accurate hardware= easier to set up right and duplicate the same results over and over...

Also new this year will be my building technique... I've changed up the assembly sequence for my airframes and that should allow me to build them faster and straighter.

Hopefully I'll have some of the hardware back from the cutter in a couple weeks.....

I'm jumping in on momo's TV blog here, and let it be known, I'm a huge CSILV fan. Only TV show I watch. Our Tivo has nothing but CSILV and Family guy recorded.

Okay, ***. Grissom and Sarah are going to get married. Who freaking cares. Just saw it in an ad for next week's episode and I'm furious.

Bring in the fonz. This show is junk.

Well, at this year's ETOC, my nerves got the best of me, so I ended up knocking myself out in the first round. Not being content to just sit on my arse all evening for the 2nd round, I decided to dig out my camera from my bag and put some memory in it. I stopped by the Hotel gift shop and bought a pad of paper and a pen. I drove over to the facility early and got an opportunity to take photos of all the 2nd round qualifier's planes. I also sat and took notes of the build details of each.

What a great opportunity to see the absolute best foamies in the world! The ETOC is still the leader in new technology for indoor design.
After collecting all that information, I formatted everything and wrote up an article for Quiet Flyer Magazine. After quite a wait, the article has finally been published and can be found in the November issue. I don't have my copy yet, but you can see it on the Quiet Flyer website in the 'current issue' section. I hope to get my hands on a copy of the magazine soon.

So what is the cool stuff going to be this indoor season? I'm sure more 2.4, as well as more of other details.

Back to foamy design...... with that little Ballerina I built last week, I had an opportunity to try the now common 'heat shrink hinge' method for control hookup. Wow was I incredibly dissappointed. I had used it once before on the Hobby Lobby "IMAC" plane that we had to fly in the 06 Pyramid Freestyle. I removed that setup from that plane as well. The friction and inherent binding that comes from using that method is just horrible. Well, needless to say, I won't be using that method anymore.

I've been designing a long doggone time, and one of the things that you end up needing to do if you come up with a lot of original designs is you'll need to come up with a lot of original names.....

Well, anyway, what more perfect name for a freestyle plane than 'Ballerina'.

Unfortunately (and fortunately) my buddy Jerry (also a designer) already applied that name to a tiny little foamy he designed. Really the name fits very well, and the plane is fun so no worries.

As for the plane, I built it as a bit of foamy building practice without the time cutting parts. Jerry gave me this kit a couple years ago, but I never had any time to build it until this past week.

It weighs 49 grams rtf and is a lot of fun. Its not an airplane I'll be flying for freestyle or precision, but its definitely got the cute factor going on in spades.

More work going on.
I inventoried all of my gear from last year and all of the remaining supplies I have left over.

I also spent a little time 'tuning' the drawings of my next build. I'd like to get something cut and assembled over the next week, but my wife and daughter have both been sick with an early fall cold (as have I), so I may have to wait. Maybe I'll get lucky.

This year is going to be exciting from a technical perspective atmo. Last year, people really pushed things 'out of the box' technically, and I don't think this year will be any different. I figure just about everyone is working on something or has a designer working with them on something new. I have my own bag of tricks, but I won't give them away.

One thing I will say is that I will likely go all monoplane. I have designed and built countless biplanes, but I always have trouble building one as square as I would like to. I have developed a method for building monos that works well and I'm gonna stick with it (its really an adaptation of how I've seen others build monos).

So normally when Max is in the office banging on the keyboards all night, I'm hanging out watching some TV. So, I just decided to start a blog about the TV shows I watch while you are all on the computer!

So, yes, I watched the entire season of Rock of Love; and yes, I like Bret Michaels. Oh by the way, Max liked watching it too. But not because of Bret, it may have had something to do with all the chick on chick stuff. I hate Lacie, and they totally gave her waaaayyyy too much time on the TV! She's so ugly and disgusting. Anyways, all along I really liked Jes and I was really happy that he picked her, but what the H? She came out at the reunion and kind of dissed Bret, telling him he should have picked Heather! Lame! Why did I even watch that show?? I hate TV! Now, I have to decide if I'm going to watch I Love New York or not ... yes, I am pathetic!

Just watched the DVR'd premier episode of The Office. Loving Jim & Pam (PB & J). I'm over Dwight and the blond. Michael is still a crack up!! He's just so sad and adorable at the same time. Rabies?? LOL!

Watched this one too. Like the story line with Ryan as the new Corp boss. Creed is classic!! I loved how he just showed up with new hair! Seems like he might be getting more airtime this season. And of course the new company logo and web site are awesome...


We also watch a lot of CSI, Family Guy, Law & Order and I'm trying to get into a few other shows. We'll see what I have time for ...

After having my U-Can-Do sitting a round for a while I decided to sell it. I pulled out the receiver and was about to take it to the LHS when my wife talked me out of it and I put it back in my trailer where it sat for a while.

Saturday I took it out and decided to give it a run just to keep the Saito .91 happy. I ended up flying it several times because I had forgotten how much fun it was! Its like flying a giant foamy. Its a fun break from all the serious IMAC flying.

I'm glad I kept my UCD.

I've flown the sim all summer. Even though I've had little time to get to the field, I managed to get in approximately 30 mins of sim time each day. While I would have liked to practice precision on it, I don't find the sim works as good as 'real' flying for precision work. Its great however for Freestyle work. I always fly to music as well.... everything is done to the mood and beat of the music.

Real foamy practicing got going today as well. I took my beater foamy from last years bunch and spent time under the lights at the local churchyard. I don't have anywhere inside aranged yet to practice at. However I do have a huge open church parking lot that never turns off the lights.

Sun was down at 7:20 or so, so I headed over with some charged packs and tore up the sky for a bit. Always fun to do that.

Another good subject to think about has been music. I literally was finding music the day after the last contest from last season. I'm hoping I've found some good stuff.

First of all, Please allowed me to say sincerely sorry to all the people who supporting SD-Models for the past years.
I am the owner of SD Model, I have lend around 300,000USD to help one of my friends in Hong Kong</ST1 for ARF airplane production. But finally his business is gone. I have no choice but only to pay the factory rent and workers salary for him and then take over his business. I donít want to see so many excellent works lost theirís job..<O</O
Unfortunately I only have the experience in making the airplanes and have no much experience in sales. I canít find the right way to promote our models.<O</O
After discuss with my friend Aling, the chairman of Thunder Tiger I recognized in order more hobby enthusiasts can know our models and fly our models, Joint with Thunder Tiger is a wise idea for me. Since Aling, The chairman of Thunder Tiger He is a successful man in sales target. And is the right person I am waiting and looking to promote our wonderful models in the past years.<O</O
Wish all of you have a wonderful day.<O</O
Best Regards <O</O

Well, it is time to get kicking for foamy season.....

I've started talking with all my buddies looking for Foamy Freestyle and Pattern contests to fly in. Seems like a few have gone by the wayside this year.

I'm also working on getting new birds together to see what works.

My goal this year is to get down to one airframe design for each discipline and use it all year. That way, I will focus on practice of the known routines and on my freestyle.

Realistically, I spent too much time 'perfecting' my airframes and not enough practicing each segment of the comps... I don't plan to make that mistake this year.

So with that, I'm starting early.

I've managed to get some good motors which appear to be tops in performance. If I stay with the smaller/lighter Pattern planes I ran last year, then I'll stick with the Mighty Midget F3P Motor. However, I may end up with something bigger and that may necessitate a more powerful motor.......

Today was useful, because I had jury duty.... It let out earlier than work however, so I came home and ran motors and props through the wattmeter....

Here is one of last year's airplanes geared up as a test mule for this year...
