Default OS 160

I recently purchased a Great Planes Giant Aeromaster ARC and am looking for an engine for it. MAN tested this plane with an OS 160 FX and according to them the plane had enough power to do normal aerobatics. I really don't want to put a gas engine in it, and yes, I know all the advantages of using gas for larger aircraft. Will the 160 be enough to pull around a 17 lb biplane or will it be a complete dog? I'm not looking for 3D type performance from this aircraft, but I would like enough power for regular aerobatics. Thanks for your help.

Cheers!

i dont know for this plane but it pulls the pattywagstaff just fine. it wont do heavy 3d moves but will do all your basic moves. the patty weighs around the same when completed. furthermore the giant areomaster isnt a 3d airplane. it is to be flown like a scaleairplane. i have a os 160 on my gene soucy and man it is awesome. that is one powerfull motor. go with the os 160 .

Only one person has experience with the OS 160 ? I need your expertise, share your thoughts on the performance of this engine and how you think it would work in a Giant Aeromaster. Thanks for your help!

Cheers!

i think it would be perfect in the areomaster. it wont be a rocket or nothing but it will have plenty of power to pull the biplane. i am looking at the giant areomaster and i think that i will get a gas engine for this plane. this will be my first gas plane. dont let me talk you out of puttting the 0s 160 on it though because that is a great engine. run 10% nitro put in a os number 8 glow plug and a 18/6 or 18/8 prop thats the magic set up for the os 160 fx. i am looking at zanough engines for the areomaster. any suggestions for a gas engine for this model.

I have one in a Morris 120 Balsa Nova, inverted with a JTec square muffler, weighs 14 lbs. 18x6 Pro Zinger prop running 10% nitro, turns the prop at 9200rpms. Very reliable engine so far. It pulls the BNova as high as I tell it to. Very good throttle response.

The 160 is a great engine and will probably fly your aeromaster OK. The Aeromaster may be a scale plane but it is also a great performer with enough horsepower on the front end. I would however be concerned that your probably going to have to add weight to the front of this plane tp compensate for the small engine. I would reconsider.

Can anyone tell me why the 160 would make a rattling or knoching sound at mid range rpm. Thx

Could be leaning out, or maybe too much prop.

I agree.Good chance of the bearings also. It's the only sport engine I ever had fail with very limited time on it.
