How would this model fly with just R/E? I'm not a big fan of unnecessary complexity... Would prefer to do a build without ailerons/flaps.

May need more dihedral for only R/E.

I don't think flaps are needed, but I would be more inclined to do elevator and ailerons, and drop the rudder, if anything.

Ya, rudder is a waste of a channel. Good for using on pan if anything.

I agree flaps are probably not needed. As I was covering the wing I decided to cut the servo slots and use them as they were provided. Might help with landing in tight spots when it's windy!! Time will tell.

I have the copilot on aileron and elevator and the rth from the eagletree unit on rudder and elevator. This I hope will allow return to home to work but the wings will remain level during any rth turns causing a rudder only turn. I hope it works ok.

I added the toroid to the GPS due to the long wire run to the tail. Its unsightly but I hope it will help reduce any interference. From the outset I intended this plane to be functional and easy to work on. Asthetically it's no looker. The stockings are a good example. They have left the plane an unusual colour which will divert attention from the torpid on the tail lol.

CG seems like it will be easily achieved with the gopro and a 4400mAh flight pack. A receiver pack is being added with an external 8 amp bec due to the amount of electronics on board. This will help offset the added weight of the larger than recommended scorpion motor.

My 8ch rx is full without room for pan and tilt. I don't mind not having pan as the fov from the gopro is massive but tilt would have been nice. I might have to add a sloped mount to get a better view of the ground while in level flight. I don't want any airframe in view of the lens.

More soon.

Regards

My guess would be that it will be way to much motor.
I would try

8-) typically not in stock! Whats up with that? So often many motors are backordered. It can be very frustrating.

I have this motor

Wow that looks so good, its very nice and clean !!!
The GoPro Hd can you tell me which pin is + and - on the mini USB and if you power your cam from the main battery or if you have a separate battery just for the video tx and the cam.
Thanks,

If you are in the US, you may want to take a look at these:

or

The TGY motors can actually be used as a pusher by removing the shaft from the can and inserting the propeller end of the shaft through the can sticking out the "back". Then mount the motor as normally and install the prop adapter to the shaft not using/needing the can/prop adapter.
