Hi all.

As my co-flyers like jana.f22 and v2eagle have already came up with couple of builds for this sweepstake, here is my entry for the RCI 6th sweepstake 2015.

Almost completed, Only electronics are yet to be fixed and the tail fins. I didn't fixed the fins as it will be little difficult to work inverted while fixing the electronics.

Detailed build log will follow soon.

Regards.

Its completed and flew it last Sunday. Maiden was done by jana.f22 as i never flew a jet before.
Though it was not a complete success, it was rolling instead of banking or turning towards left/right.
Will post the video soon.

Please help me out, what could be the possible reason !!  ???

and if possible, increase win.g span and also softly try to give the wings a 2-3 degree dihedral.
A fine lookin model.
Awesome paint scheme. Sir

Wing area is less compared to the size of prop used and size of control surfaces.

Just reduce the throws to less at 50% with about -30% or +30% exponential depending on which ever your radio to make the center stick soft.

It should fly well in this configuration too once you trim it.

Thanks Tanmay.

It was in my first to do list to send a pm, Sandy sir. Thanks a lot.
I will do the changes as per your suggestion.

Even its little heavy because of the black chart paper.

Any way here is the video. Please check this.
