Hi guys,

Its been a while since i have been flying my hobbyzone supercub.
It is a perfect plane but i am having a strange issue...
The plane moves right on its own...rudder controls at neutral...
And yes, I have checked the rudder (Even trimmed it b4 flight) and the servo linkages.
Is it the thermals or the wing or wat?
Tried everything i knew, adjustments from servos etc. but doesn't seem to work.
Wondering wat 2 do?

is it on the ground or in the air...??

how many times have u experienced this??

Almost everytime...
Its in the air...

3  ch or 4 ch...??

3ch

possible chances for wing dropping to one side (turning)

1> warp in the wing ( twist at some place on the wing)
2> while assembling the wing to the fuse center  of the wing not matching the center of the fuse ( leading extra  weight on one side and hence dropping)
3> imbalanced  wing. ( one side  heavy than the other)

also : flying cross winds...

check each one at a time and  post the results

Ok..
How to check point no. 1 and 3?

for 1> keep one side of  the wing on the glass  table. and check if it sits flat. if not, the place where u feel the bump is the place its warped.

3> insert two pins  in the center of the wing one in  the front and one at the back. tie a loose thread and check the balance or just use the fingers on the pins to check it.

Ok... vl update the results soon...
thx
