Walter,

The Saito 1.50 is an excellent choice for the T-craft. We flew the prototypes with the 1.20 (good power) to the 1.80 (torque rolling power). The Saito 1.50 with an APC 17x6 prop on 30% heli is more power than you need. For scale looking flight the Zenoah G-26 (just replaced the G-23) is the best choice along with the Saito 1.20.

Good Luck with your project!

Regards, John
