Hi Bob!!!!
how's your twin project coming along?
Have you found a plane for it yet?
I think that a nitro planes katana or Edge 540 for a 50CC engine would be right (although the wife doesn't think so). but anyways keep us posted, also if anybody else is having different results with their twin echo let us know its interesting to know that the gas/glow configuration works very good!!!
I adapted a walbro carb on my MAGNUM 1.80 engine and runned with a gas/glow fuel that contains 10% oil and 3% nitro and the results are "SUPERB" nice transition, low idle but I don't have a tach to measure it at this moment, I will take pics and post them later, I thought that I was going to end with a useless engine because there is no way I'm going back to expensive glow fuel but this way I recovered and I'm thinking of using it on an 80" profile that I will design for it I'll keep everybody post on it.
Later CONVERTS!!!!!!!
