I would agree with Edwin on the ST90 for power. I have the Hollywood Zero with this setup. It is low cost(150.00 new) and is reliable and way powerful. I just got the
P-47 andam about to start it. Let me know if you have any questions while you are building it. The Top flights are extremely easy to build just remember to completely read the instructions before you build. This will give you an idea what is coming next and make more sence of what you are doing now. I made some avoidable mistakes on the zero by not doing this.
