Wondering if tail wheel from Robart could be left freely to caster as it is on actual aircrafts. I'm thinking on using rudder and differential throttle on ground to do the steering if it's possible to do with G38s!. I know with electric set up it's doable but gas is different. I also have Robatr's retractable tail wheel assembly, wondering if i can use this also by making if in fixed retracted position.
