Miss Geico jerking side ways

[jpracing1997]

I ran my geico with a 1515 1.5y on 6 cells with a 642 prop and it barrel rolled and snatches sideways when its running? Any suggestions as too why. Is it too fast for this hull or just a balance issue. I had the batteries 30 to the rear and strut adjusted.

prop walk? have you tuned your strut height?

you might need a cupped prop to assist with torquing..Try a 42x55 grim prop..Raise the strut up a bit..Sounds like your getting too much bite with that prop with that setup..Also..If your looking for top speed runs, you may need to ease into the throttle instead of "Flooring" it..
