Just wondering how this engine compares to the zenoah GT-80. I'm thinking about pulling the GT-80 off my Hangar 9 sukhoi and bolting on just a little more power.

Tony Hallo

It is surely islighter than the GT80. I thought about buying one last year and ended up with a D&B 5.1 twin. Just didn't find much intell on the engine. It cost as much as a 100, I think here in lies the problem. Good luck and post your results.

Also, how does the ZDZ 80 rv single cylinder compare with the twin? Do either of them suffer from the starting difficulties that I have read about on some ZDZ's?
Thanks

I have the ZDZ 80 single and twin. These are the original versions with aluminum nicasil cylinders, about ten years old. The twin is not quite as strong as the single, maybe 200 rpm down with a 26x10 prop. No starting problems. Any starting problems are likely due to your techique, carb needle settings and tank plumbing. Both are very light engines for their displacement. My advice would be to get the single - less money and a little more power and still smooth enough. Or get the new ZDZ-90 for even more power. If you must have a twin, get a DLE-111.

That GT 80 weighs a ton, so I'm not sure going with an 80-85cc will give much if any gain in horsepower by the time you add the noseweight to balance it out again. If your cowl can clear it, I agree that going with 100-120cc twin will make more sense. Figure out how much weight on the nose to balance and select 100cc class motor to match.

zdz 80 rv . love mine, 26-`10 prop, gt 80 prop? weight? mines in a 33% extra. hovers all day long , doubt the zenoha 80 would, allthough they are a great workhorse mtr and run smooth(twin) just move your equipment batterys foward and hold on.

Thanks for the replies. I do have a DA100 that I might try to put on the front of the Sukhoi. I need to check the weight difference.Also I need to make sure that the measurment from plug cap to plug cap will let me fit it in the cowl without having to butcher it.Maybe the DA100 would be my best bet especially since I don't have to spend the extra cash.
