Cold weather and wind has hit. Time to practice the flight sim every chance I get.

A week ago hubby and I went over to our friend Dan Jones Flying Club field and flew litl girl.
No, sorry i didn't fly her. Hubby wanted to make sure her engine was functioning correctly. But he said she is a sensative one and he might as well teach me on his foamy.

Sad part of the whole afternoon was Dan's planes controls stuck and his favorite plane did a complete NOSE dive.

Now to find an indoor flyinf club so we can fly the small electric foamies!

I finished my new precision prototype. I'm really happy with how it turned out.

Its the airplane I was using in the Foam Milling thread I put up.

The airplane has a 33" span and is 37" long. My goal was to get it finished at 130 grams RTF, however I did not make that goal Instead, It finished out at 124 grams RTF!!!!!! To say that its light is a gross understatement.

I don't know when I'll be able to get it in a gymnasium for a test flight, but I hope that will be soon.

I love all types of models and all types of flying, but foamys just plain rock!!!!

my father and i went to fly this past weekend and we, being poor and resourceful, checked the dumpster on the way out. to our surprise there was an very large yak 54 in there. wow. slightly busted up though. the landing gear was bent and forcefully removed, the right wing was a little bit more flexible than it should be, but all told i think it is repairable. my thing is i want to find out who the manufacturer is in case we need to order a new wing and to replace the jacked up landing gear. here's another possible clue. it's electric. although the previous owner wisely removed all the obviously expensive parts it has no fuel tank, nor a place for one, and the motor mount is for a very large outrunner. if anyone has a clue who manufactures or distributes this plane i would like to know. thanks.

Everything in this world is relative....

Of course in the world of foamys, airframes just don't last as long as their larger brethren. Much like butterflies or Luna Moths, they fly around gyms and meeting halls and often meet their fate much too early.....

However, I have a few foamys that have lasted much longer than I'd ever expect..... In total, I have about 8 foamy airframes that are either ready to fly or just need a reciever plugged back in to get ready to fly.

In that gaggle of foamys is the first indoor precision airframe I did - The Sentinel.

This also one of the lightest airframes I ever built. In original configurationg it finished at 3ozs RTF. Its still one of the best flying designs I've done for precision.

All told, this airplane has been to at least a dozen indoor events! It easily has over 200 flights on it as well.....

Could not sleep last night, so I headed out to the garage at about midnight.... Painted up the fuse of the foamy I'm working on. Its turning out pretty nicely...

Many may have seen my "My First Design" blog post, and see that I came in overweight and over sized for my design. Plans have changed as for electronic set-up for that one (See "My First Design . . . Updates 3).

My "Second" Design is just a scaled down version of my First.

Changes:

28" Span
30" Fuse
Thread for strutting in wings rather than Carbon.

Set-up for it is what my origional plans were for my design:

Hacker A10 9L
Castle Creations Phoenix 10 ESC
Dymond D47s on Rudder/Elevator
Futaba 3154 on ailerons
JR 610UL (Cant wait until I switch to Spektrum, and the new 2g rx is out!)
Thunder Power 2 Cell 350 mah batteries.

Airframe is finished (minus motor mount).

Weight . . . . . . . . Drum Roll Please! (You know why if you've seen my other blogs)




























2.1 oz

Very pleased with that weight as of now. No milling (would be around 1.5-1.75 if I did - will happen later - want to test design first)

Looking at around 5.5 RTF Weight

Going to lighten servos, and anything possible to get the weight down . . .

Pics to come!

Change of plans for motor/servos ect.

Going with:

Axi 2204/54
Jeti 8 Amp ESC
FMA Direct M5 Rx
GWS Pico Servos on Rudder/Elevator Pull-Pull
Eflite S75 on Ailerons
Thunder Power 2 Cell 480mah Batteries

As of now, I have motor installed, ESC installed, all 3 servos installed (minus aileron servo arm), receiver installed. Weight as of now is 6 oz flat without battery, pull-pull linkages, carbon connectors for ailerons, and control horns in surfaces.

Looking at around 7 oz for all up weight. Beginning to think it isnt that bad for 450-475 square inches of wing area.

I am also building another plane for the JR Indoor Festival as well. (Hint: See My Second Design in my blog).

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.
