RE: Tower Hobbies .46
I have a Tower .46 in a Sig Senior, running a 11x6 Zinger, on 10% nitro, castor/synthetic blend. Engine likes the prop fine has been very reliable. Oh, I'm at 1700'.

Edit: Let me remind you that the Tower .46's muffler is really a mini-pipe and you have to set your hi-spd needle accordingly.
