Ok here is the prototype drawing.....
If you see some similarities to the 3Dx then you are correct, I needed something to go by in the way of size so I can keep the same AUW for the power system.
From there it gets different....I changed wing LE and TE angles, wing location and stab location relative to thrust line, fuselage side area and maximum fuse height location for what I hope will be a solid KE flier.
Control surface proportions remind me of my Flip 3D Most of the changed I made are what we do in pattern to get a neutrally stable model, my goal is to get a solid precision flier (as best as you can with something like this) yet retain a good envelope for 3D.
I may get it up this weekend...I may not, will report on how it flies when I do.

I think I've found an indoor venue for us in Calgary Chad. More details when available, but it's looking good. 28 foot ceiling, 10,000 square feet plus!
Of course I'm an expert!

Need help on the electronics!
I'm hoping someone wouldn't mind giving me some help please!!!
I purchased 2 sheets of Depron foam and have downloaded the plans for the 3DX. I would like to use a brushless motor setup with LiPoly packs.
I know very little to nothing about motors, speed controls, etc for these planes. Would someone please be so kind to inform me as to which motor, speed control, servos and LiPoly packs (voltage etc) to use? What would be a good all around charger to use as well as prop size for the motor recommended.
I know this may be asking a lot but I would really appreciate the help!

Gary, call Marc tomorrow.
He is a great help for us guys getting started. If yoiu don't have his # let me know.
You didn't happen to get an extra sheet of Depron that I could buy off you?
If not, can you tell me where to get it?

Did get in a short flight in the parking lot tonite under some lights, seems to fly quite solid, and very smooth I was pretty impressed.
I do have a problem with my speed control cutting out, not sure if the cold temp outside was causing the batteries to output a lower voltage and cutting out the ESC.....only does it at high throttle. Anywho I will try again tomorrow in daylight when the temp gets up there
I would offer some help Gary, but like you I know absolutely nothing This is my first real venture into electrics which is why I avoided the brushless, LiPO route to start
It takes 2 sheets of 15"x39" Depron to make one of these models, you need the 39" sheet or you cannot do the wings from one peice.
I did try 2 different props so far (lots more to come) all APC
12x6E (electric) - much more thrust than the 11x5.5E, hover on fresh charge at around 1/2 throttle
11x5.5E - not as much thrust as the 12x6, barely able to hover on fresh charge
Other sizes on the way....
Although I am sure that the last two are not suitable but I want to try anyways, if the system can handle it probable the 13x4E will work the best.
Anywho so far my setup is
- Futaba R114F receiver
- Futaba 3107 servos (3 of them). I may replace them later with the newest 3108's which are about 1.5g lighter each
- Sanyo 8 cell 720 4/5AAA NiMH
- GWS 350C D gearing, props as above
- Castle Creations Pixie 20P ESC
All up weight was 350g, or 12.3 oz.
