RE: DIAMOND DUST RC LIVES!!!!!
The 35AX would be a fun combo on the DD. I flew a DD with 32SX and Macs pipe. It was easy to launch.
You mentioned the Webra 50. I love that engine!!! I'm flying 2 of them now. Both of mine have the old style tube mufflers giving a nice boost. You are right about the light weight. They are louder than an OS 50, but they give amazing power on only 10% fuel. Like I said, the Web 50 is one of my fav engines.
