My estimated wingloading is 10-11oz/ft^2

All electronics including the antenna are concealed in the forward fuse.
Maiden soon.

Mr. Boogie
The numbers look fine, I love the AUW. When I built the first proto for the contest I was shooting for 14oz and tried to design it realy lightweight. I sheeted the fuselage and had a contest balsa plate wing and it still came out at 19oz AUW. I am working on proto number 2trying to sort some of the little problems I encountered out of it. Might try a nano model of it before going forward with the changes.

Cheers,

Eric B.

AirX,

Are you referring to a Proto F35 build or another plane. Either way, is there a post that you can refer me to that has details and pics?

I've been silently checking out the nano thread, great stuff and ideas!

Thanks Steve,

I expect it to be slower than my F18/SU27 pusher jets, and to this end I am wondering if my handlaunch should be a javelin throw or a strong level toss at the horizon?
Also does anyone know if torque roll is an issue with edf planes of this size?

Thanks,
Boogie

TN,

When I sized this bird I was looking to be about the same size as the Flying Styro F16 and still have close to 100% FSA. I'm pleased to be in the ballpark sizewise and weightwise.

I hate maidens, and I love maidens!

Just referring to my contest entry and how differeny materials effect the build weight.

Maiden Completed!

The wind finally cooperated and this morning I finally got to sucessfully maiden my F35.

Launch
I launched with 2 clicks of up trim and full throttle. A level toss afer a few steps did the trick.
At altitude she flew nose up with 1 click of down trim (past neutral). I think my thrust tube is aligned with the thrust line so next flight I'll move the battery forward a little.

Flight observations
I kept the flight to a basic pattern with a few rolls thrown in (no loops).
She's no speed demon but quick enough for a lightweight EDF (IMO). Just a bit faster than my parkflier (brushed motor) warbirds. The rolls were fast and nearly axial. Just above half throttle flight was also sustainable.

I climbed to what I considered to be a safe altitude for stall testing and eased off the throttle while increasing up elevator. Stall is a violent wing drop to the side. I pointed the nose down to gain speed and noticed a left/right oscillating roll for a few seconds before I could get control back.

It took me three passes to set up for a landing, the glide seems to last forever. I did notice that off power gliding showed a nose up attitude, so I might be tail heavy.

I really love the high pitched whine that the microfan generated. It was so cool to hear (and watch) the F35 go by full throttle on a low flyby.

I flew for about 6 minutes before bringing her in, a recharge of my battery shows that I used 444mah. Most of the flight was at 3/4 to full throttle.

All in all an enjoyable first flight and first EDF experieice. I think I'm hooked.
I'll see if I can talk a friend into videotaping in the cold.

Does anyone know what might induce the side to side rocking after stall?

Don't Launch Yet!!!

Mr. Boogie looking at your prototype your horizontal tails will receive spoiled air from your wing and thus result in problems with your elevator controls. It will make you use full stick movement for controls on pitch, unless you have a certain degree of pitch down from root to tip it's difficult to tell from the picks but please beware..
