On a semi-trialing arm rear suspension you can get wheel hop under braking and, rarely, wheel hop under acceleration due to the amount of anti-dive in the trailing arm geometry. Increasing compression damping on your shocks will help reduce wheel hop. You can also slot the rear crossmember allowing some adjustment of the trailing arms.
