Given the light weight of your motor, you're probably right about going for the pull-pull rudder servo for your electric power setup. I'd get one of those Du-Bro HD pull-pull rudder horns instead of the factory stuff. I have the Du-Bro horn on my Phoenix Extra 330, and it's bombproof.

I have the V1 with the heavy aluminum gear, so if you have CF landing gear, even more reason to shift weight forward. At least with different sized batts, you can move your CG around.

As far as tailwheel, I ditched the stock setup (too heavy and clunky) and put on a Du-Bro tailwheel kit. I'd like to eventually convert that to a CF leaf with a tiller (from Redwing RC or Chief Aircraft) but the Du-Bro setup will work for the maiden flight.
