Remember its an old skool grass track.. you dont need huge jumps & bumps to make it demanding ! And remember the smoother it is the more chance of my Pred staying in roughly one piece
I might even run my TRF Dynastorm as well... or possibly the Dyna-Mid... instead of the RB5
And possibly a Top Force in Vintage.. ??
I got a stick lipo you can borrow Chris if that helps ?
