Profile fun fly
With any of the profile type planes I highly recommend some type of flying "wires" on the tail. I had a Sig Faser which flew very well. It was lost to half the stab coming off in flight. There isn't much to keep the stab from bending. I used some nylon thread on a Thunder Tigre Extra profile (really heavy) and it really helped as it stayed in trim better. The Profile P-51 is also a good plane. If you are planning so much modification and want a profile why don't you use the wing design from the Uproar and design your own fuselage? Bill
