Sanjay Sir over all we did not like the flight characteristics of this model. Roll axis instability was too much and was not getting corrected with trim as well as with throw adjustments it had a tendency to roll over always. We did quite many test flights today. I think it may be due the amount of wing curvature which got incorporated during build which you can see in pic below.
Depron F-18 from Tom He Plan for the 6th Sweepstakes.
It was almost totaled in my hands trying to improve it. May be Gusty's Shillong F-18 Spell on me.
We have decided to retire this one and make something else.
The other two models F-22 and Sukhoi with canard was on rails as far as flight characteristics in comparison. Param had a blast rolling and looping with them. Will post some clips.
