Though I've been flying for wayyy too many years, I've only been flying giantscale for about a year.

I rebuilt a Terry Boston built Carden 35% Edge two summers ago and have really enjoyed thrashing it around.

It was bound to happen eventually, so fate reared its ugly head today. While in a low hover, (tail about 3ft off the ground) the engine flared out and the airplane slowly fell to the ground.

It did the most perfect tailslide anyone has ever seen, and the rudder stuck about 10" deep into the mud in the beanfield that borders our runway. After sticking in, the airplane simply fell onto its lid very slowly.

I got off lucky! The rudder is broken and needs a total rebuild. One elevator servo is stripped and I broke a new Vess prop. No other apparent damage to the airplane though.

To fix it, I'm going to pull the rudder sometime soon as well as the DA off the nose. I'm going to send off the DA and I'll rebuild the existing rudder and recover it. I might take this opportunity to make some improvements and change the covering scheme slightly at the tail to make it my own I'm also going to go through the rest of the airplane in full to check for any hidden damage that would show up later....

The way I see it- I got a free airplane today....

Well, its finally coming back together....

I decided to replace the old hollow core door with a solid core door. I can't believe how much that thing weighs!!!!!! Then again, its lighter than the granite worksurface my father tried to pick up for me when he was getting the new countertops for his new house.....

I mounted the door on the bench I built, then I squared up the thing. Checked it for level every 6" on both axes all the way down, shimmed it where it was not level.... Its smoooooooth. I also anchored it to the bench at the back to keep it stable and prevent my adjustments from getting moved...

Then I topped the board with 1/2" sheetrock and checked everything for square...

Finally, I took the old pegboard and re-installed it, but did it right this time with spacers off the walls. I also hung the old parts divider to get it off the bench....


Ohhhh yeah, notice the fire extinguishers? If you don't have some mounted near your bench, you are asking for trouble.....

Hey guys,
I have the airframe finished, and motor, ESC, aileron servo and rudder servo installed of my third prototype of my own design. First design was a little large for my liking, so I scaled it down to a smaller version, with a few little tweaks such as larger ailerons (to scale). That one seemed a bit small, and the wings somehow got warped. The small one was a tad heavier than what I really wanted too.

Needless to say, I am on my third version which has an inch bigger wingspan, 1 1/2" longer fuse, wing chord is same, as well as distance between the wings. Also used carbon in the wings of this instead of thread.

Finished airframe weight is 2.15 oz. With motor, ESC, aileron and rudder servo installed it weighs 3.65 oz. Threw a heavy Eflite S75 (actual servo will be almost half the weight), and battery, prop, o-ring for prop saver on the scale as well and the scale reads 4.75 oz. I am figuring I will be at 5 ounces after I add all of the pushrods and control horns. Real happy with the estimated weight considering my smaller version weighed 5.3 oz, and this one is bigger.

Will post pics as soon as I get home from work after school.

EDIT: PICS NOW POSTED FURTHER DOWN.

Last year I was lucky enough to have fellow Indoor competitor AC Glenn flying with me here in Memphis. Practicing by yourself is not nearly as productive or fun as is practicing with a friend.


Another significant benefit is that I come from more of a 3D background and AC comes from more of a precision background- my successes have been in freestyle contests, and AC's have been at the NATs pattern comps. AC does not need my help much with Freestyle anymore, but I definitely still need his assistance with pattern....


Bad news is that AC went away to school for this year, so we won't get to practice in the gym as often as last year, however he's not too far away to pop over for a weekend.


So last night, he came to Memphis and we headed for the parking lot I normally practice in during the winter. I get more flying time out there than pretty much anywhere else. We were not practicing so much last night as we were trimming the airplanes and picking props.


AC flew the full FAI pattern with my new airplane, and I flew parts of the FAI F3P pattern with his.

All in all a lot of good fun.....

Well, the house is now through its 'warranty' phase, so its time to get a termite contract. We signed one the other day and made arrangements to have the house treated shortly...

Unfortunately, that means I have to pull my workbench out....... so they can get back there and finish the treatments.

I decided to take this as an opportunity to put a new work surface on my workbench and to clean up and organize all of whats up there........

This is what it looked like before I started.

I used to keep a pretty clean shop, but having less time means somethings gotta slide, and unfortunately, for a little over a year, that's meant no cleaning of the workbench when I'm done.....

Guys this is a dummy post, from a dummy of course to see how this freakin Blog stuff works.

That darned MadMax has all these technical stuffs that us older dudes just dont understand.

So WTH, at least I'm trying.

My friends have been telling me about Comet 17p/Holmes that unexpectedly had an outburst and became visible to the naked eye. So I grabbed my camera tonight and shot off a few pics as best I could (I modified the contrast in PS to make it show up better). Its the little fuzz ball beneath the brightest streak. If you get a chance grab some binoculars and go check it out, its pretty cool!

Well, I finally got my hands on the foamy hardware I designed. I drew this hardware up for smaller 3d oriented birds that use the Dymond 4.7 gram servos. Included in the set are landing gear braces, pushrod braces, firewall and various horns. They have shorter hole spacings to work with the Dymonds which have correspondingly shorter arms.

The smallest horns are for verrrry small projects, but I'll probably not cut them on sets of the hardware.

The cutter was very generous and sent me 3 sets to test, but the grain is not oriented right on the sheets, so the horns are a bit more flexible than I'd like....

I also picked up a case of depron today at the LHS so I can build something to practice freestyle with...

Flying my new prototype I decided I wanted a little more power. The motor I was running had plenty of power without the drag brakes installed on the airframe, however when I installed the drag brakes, I found that it did not quite have the umph I wanted.

The motor I was running was a Chrome Chaos from 2DogRC. Its perfect for 4-5oz airplanes, especially freestyle birds. I decided to outfit the airplane with an AXI 2203-46 and a Thunderbird 6 ESC.

I wanted to cut the weight down on the Axi, so I cut off one lug and ground the sides of the prop mount slightly flat. The motor basically did not drop any weight considering the resolution of my scale- that was not worth the effort.... Then I looked at the T-bird. It has leads on it which are finer wire than the 9amp version. They're also shorter - too short for the long airframe I'm working with. To fix that, I slit the heatshrink covering and removed it. I replaced the ESC servo lead with a longer one of the same fine guage wire, I also replaced the power leads with some longer wire. Then I slipped the heatshrink back on and mounted it on the airframe.

All told, I gave up 2-3 grams on the power system.... .
However, then I remembered another difference....... and decided to quantify it..... Every motor seems to have a prop that it likes best. Thats true whether glow, gas or electric. With the Chrome Chaos, it really liked the carbon fiber props I've been running. The other benefit is the fact that they are very light.....

The Axi does not have a shaft that will fit the carbon props. So, I therefore need to run either the APC 3.8 which weighs almost 6 grams, or the GWS which is about 4grams.

I hope that there will be some new motors coming out this year, and believe there will be. In the meantime, I'll fly what I've got. : )

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 . . .
