I have a SkyShark Eagle and was looking for some help with a glow engine choise. I have a Moki 1.8 and a OS 1.60 FX. I also have the Great Planes Pitts (witch i know they say the 1.60 will fly). I plan to use a Moki 2.10 for the pitts and the Eagle is not much smaller than it. Will a 1.60 fly it "good"? Is the Moki 1.8 to heavy for the Eagle? Thanks for any help.

Having had both planes, I wouldn't use anything smaller than the Moki 1.80 in either. These are very 'draggy', as most all bipes are, and benefit from powerful light engines like the 2.10 or 1.80. Personally, I would use a 2.10 in both, if you insist on glow power. The Moki 2.10 is a real powerhouse, as you know, and will bring these airframes to life. I used 2.4 to 3.2 gas in all of mine. I liked the Skyshark Eagle the best. Good design, more authentic lines yet very well behaved, easier to maintain with the large removable top hatch / canopy, more rugged gear and wheel pants, among other things (it had a FPE 2.4 in it).

Id like to use a gasser but i already have the two Moki's. Never had them running yet but have read alot on what good engines they are. Thank you for the reply and help.

Another good thing about them is they actually run better on 5%. They are designed to run on as low as 0%. When tuned, they will start with simply a backwards flip of the spinner against the compression. They are thirsty though.

This particular Eagle was built around a 1.80 four stroke. I am willing to bet that the O.S. 1.60FX will fly the snot out of it. There is someone on here that flys it with an O.S. 1.60 Do a search and you will find a long thread about this plane.

Thanks guys! I was looking at both the pitts and Eagle side by side tonight and not much difference in size really and i know most would not agree the 1.60 is a good choise (or under powered) for the GP Pitts. And with the drag of a bipe made me think of useing the Moki 1.8.

I have got one I need to finish. I am going to use either the RCGF 45cc or 50cc.

I have a 1.80 Saito in mine, but wish that I had a gas engine instead. Saito is way too thirsty. I love the way it flies, but not very economical with this engine. Its going to end up with a gas engine. JC
