3" wheels are cool...you can see them better...sometimes when the model is way younder..all i can see is
little black thingies sticking out of my model to be able to identify if the model is inverted or not

Yeah..I tired wraping mono or tape to the wires get rid of the play. They don't last too long.
They last longer if I wrap it in the correct direction.lol

After a while..you just break down and go tail draging.lol
it's like killing 3 birds in 1 stone. Stiffer landing gear, can install correct dia axial, and tail dragging.
