Kit bashing is great fun and a little challenge that makes it far more enjoyable than just building a kit, It s my favorite way to come up with new planes for just sport flying.

king for the reasons Dennis has already mentioned it might be a little slow to couple into a roll with rudder imput but you have a reasonable setup and I would just go ahead and fly it after all that is part of the joy of experimentation. There may be a possibility that you will need to increase rudder area but then agine that setup may just impart the qualities you are looking for.

If you want to later try ailerons then fine but don,t build a new wing. Just add full span strip ailerons to the trailing edge and if you like saw it in two and reduce the dihedral but this is not really neccessary.

Your early post said 3.2 lbs. is that without the engine and radio. If so I would strtive to keep the weight down to no more than about 24oz a square foot. This will impart a gentle stall. If the airplane comes out a little heavy athen consider twisting in about two to four degrees washout on both side while someone irons out the wrinkles while you twist, that will also minimise tip stall behavior.

In the mean time 'Bash' away
