Hi Pete,

I have had this Heli for over twenty years now and it has probably only seen about 3 hours hover time. until i put it away. Yes the engine had plenty of power to hover tho I did not try to fly it but have seen one other identical heli fly and hover with no problems.

As far as the fuel to oil ratio goes I can't see that it will make the difference between hovering or not, but I could be wrong and think it is worth adjusting it to make sure. I did run mine on 25 to one with no problems.

What's happening when you try to hover? Two stroke engines are fairly simple and it may be just a case of setting your carb right tho with this engine it does have timing advance which I have not had a need to play with. It's the cable that goes down into your engine near your throttle, is it hooked up. Your running adaptors in your exhaust system....is this stock or an after market addition? I set mine up as best I could to all stock settings and it was reliable but if you have deviated away from this in your exhaust it could be worth investigating further. Stick with it and I'd be curious to know how it goes. It's probably just one simple thing that is causing you the problem.
Regards
Rudy
