Sorry I haven't been in here in a while...been a couple years since I've flown a foamboard airplane to be honest. That said, I still sell a kit for the Deamon now and then. Seems that it's still a relevant airplane.
I'm going to go out on a limb and assume that your plane is a bit tail heavy, given the use of a pretty small motor. The CG should be no more than 1" aft of the wing leading edge.
Torque roll at full speed indicates that either the motor is bogging down, or your wing is warped. Check for the wing warp first.
Nosing up, I dunno...I've never had one do that, but it may be related to the CG issue. Make sure the power pod is in straight.
You don't want thrust offsets on these as that can cause some minor, but really weird tendencies at full speed which are both annoying and limiting of maximum performance.
Let me know what you find out and we can proceed from there.
I just build this plane and I'm noticing two tendencies when I fly it:
#1 It torque rolls
#2 Tends to nose up.
MY power setup is:
EMAX 2205 2300kv motor
APC 5x5 electric prop
850 mah 4S battery
I was wondering if anyone else had these problems? The plane nosing up seems to happen when I give it some throttle and I noticed that there is no thrust angle on this plane. Did any of you experiment with adding some downward thrust? Would a few degrees of downward thrust fix this? The torque roll is less noticable and it seems to go away at higher speeds, but even at higher speeds I still have to apply a little bit of right aileron roll.
