I am throwing it together and it is time to buy the power plant, I have the 1.8 in my Hanger 9 Edge 540 and absolutely love the dang thing!
I have lots of props so I could keep them both "standard" so to speak.
I was considering going gas but I fly alone up here in northern Alberta, Canada and don't have anyone around that has ever run a gas RC engine so I think that is out.
Anyone out there running their Patty with the 1.8?
Enough power?
Would the 2.1 be a better choice?
Thanx in advance.

Lean 540, get the 2.1, you won't be sorry! The 1.8 will fly the airplane and you will be able to do the basic aerobatic sequence but you won't have the muscle to pull sustained vertical. I have the Patty with a 2.1 and it is a fantastic combination, possibly the best flying aircraft I have ever owned! I am running the Menz S 20x10 prop, 5% Powermaster Castor/Synthetic blend and an OS 'F' type plug. The 2.1 Moki is the best large glow engine on the planet IMHO! Good Luck!

I've had the Patty with the Moki 2.10, the BME 50 and the DA 50. I sold another ARF that I had in my garage to a friend of mine that had a 1.80 laying around. I told him I didn't think it would do the job, but... Low and behold, it does pretty darn good. He flies the advanced AMA pattern and it does everything that the pattern consists of and more. Torque rolls with demanding pull out power, no. But for everyday sport flying, and especially for the Advanced Pattern, it does darn good. Since the mount would be the same for the 1.8 and the 2.10, I would suggest you go ahead and put the 1.8 in her if you've got one laying around. If it doesn't work out to your likings, you could always change it out for the 2.1. By the way, another thing I wouldn't have done that he's got is an 18X8 Master Airscrew Classic prop. I always used the Menz, NX or Mejzlik. I need to look into this inexpensive Master Airscrew thing. But if you're starting from scratch, then go the 2.10 from the beginning.

Thanx for your input guys.
Based on your advice I have gone out and purchsed the 2.1 today.
I really do love the Moki's, something magic about the damn things.
Thanx again.

I have both the 180 and the 210. You made the right choice. The 210 is the way to go. Get the Menz prop, 20X10.

What surprised me was that I had an old Moki 180 and a new Moki 210. The old 180 had more power, by a bunch. All this means is that a takes a long time to break in a Moki. The 210 is just now becoming more powerful then the 180. I think I am on about the 5 th gallon of fuel. Thats a lot of flying. I noticed you said you just ordered a new Moki. I didn't want you to get nervious when the 210 had less power than your 180.

Have fun.
