Hi!
Best prop would be a 12x6 APC or RAM! 13x5 would work too.
13x6 is too big!
Yup... right on the money... as is the recommendation for the 13x4.

All are right on the upper edge for the Tower .61 engine.

I fly my SuperTiger .61's with 13x4 to get more thrust and because of the low pitch the RPMs stay high enough to keep the speed up.

IMHO The Tower Engine is a bit stronger than the ST.
