Well for the electric, you could go with a Hacker Brushless setup.... But that's no fun - a silent warbird? You may want to search for anything written here by TWINMAN... he's the local p-38 guru.... gyros are rudder would make your flying much more manageable... Taking time to break in the engines perfectly is the best first move... Being proficient at using rudder to fly an a/c is the other.

"OUT thrust" \ / - having the engines pointed away slighty to help prevent a death spiral is a bit of debate. Some have said any is good... Others have told me that a few degrees is useless, and enough to make it functional is just an eye-sore cause it becomes horribly noticeable.

If both engines are running you don't need any. But again, ask Twinman... he has had more p-38's than anyone on here... ( i think 4-5 a/c so far???)
