I flew mine with them on... Just have to make sure they don't catch when the forward pant pushes back. If seems like yours is going to then take them off. One word of warning... Make sure you take your time and set the CG perfect... or a little nose heavy. It is very critial with this plane. Also the elivator and alerons... go to low rates till you get used to the plane... I love mine and they fly great...
