we had donkey kick issues even on 1/10 scale sized jumps, the issue was tied to the way the approach was on the jump being very abrupt and the nature of the weight being as far forward as it was. We got this almost completely solved by the SCT410.3, but was still an issue on some jumps, just needed to prep the suspension by hitting the brakes then slamming throttle on this particular jump, worked fine. Other trucks ddn't have this issue like the Losi or the Durango DESC10.
