Most training wheel Vans RV pilots (excluding 10 and perhaps 14) will be advised to get the nosewheel off as soon as practical.
This is mainly due to the propensity of the shoddy RV nosewheel design that can fail because of the fore and aft oscillation of the long stiff gear leg that has a tendency to dig into the runway and act as spring to flip the aircraft over.
Has happened numerous times, and vans have finally acknowledged its shortcomings by putting out a new design front gear leg for RV's.
Big and expensive job though to replace on an existing aircraft.
Mike Seager who does the transitional training for all RV aircraft, teaches that it is important to get the nosewheel of as soon as possible, and to keep the nosewheel off the ground for as long as possible on rollout fter landing.
