Heli-NuBee

I flew my replacement OS GGT-15 engine yesterday and it preformed great. I really like the GGT-15 and hope that I do not ever have any further issues. Thanks again to Hobby Services for their prompt service.

Best wishes and good safe flying.

Here's some rpm numbers for you guys. I ran both engines with the same 15 x 6 APC propeller. The engines were not leaned out to max rpm's. The .75 glow was set the way I fly it. I fly the 15cc gas richer than the 10,000 rpm.

OS .75AX glow engine 9,200 rpm
OS 15cc gas glow engine 10,000 rpm

I think the prop is too big for the .75 glow engine. It seems to lug the engine down a little in the air. The 15cc gas seems to have a lot more torque and it turns this prop with ease. The .75 is well broken in. I have burned about 1 gal of fuel in the 15cc gas. I have the gas engine on a GP Revolver 70 and I think it has the perfect amount of power for it.

For those whose warranty has run out and are in need of repair, try RCJapan for parts. Very reasonably priced parts. Shipping was also reasonable at 18.50$. Not certain of how long it will take since I just placed my order last Friday. When I receive the parts I'll post timing and shipment particulars

Hello,

Does this engine has needle bearing?

Has anyone tried to run this engine with Glow Fuel BUT with low oil for example 5% etc?

I realise this is a bit old thread, but still perhaps someone can share some info. I'm wondering in what range the compression should be on this engine.
