And here I thought these were the PERFECT engine. All you read about is DA-50 this, DA 50 that. Don't get a Zenoah G-62, weighs too much yada, yada....I've got 117 hours on my G-62, and Ralph put his ignition on it at 100 hours. Turns a Mejzlik 22 x 10 at 7700 the last time I checked. Not one dead stick. I think I'll hang on to it. Sure would hate to have a motor quit on me doing a wall with my Wild Hare Edge 10 feet off the deck.
