RE: DL-50 engine
I used to fly a GP 45 Cap232 with a YS91. A lot of power. Unlimited vertical. But not much fun as I have to watch for stall all the time.
Everything is about choice: experiment this or that is one way; analyze this or that is another. Again it is a choice.
Outfit and fly right, gas planes can have a life span much longer than glow ones.
