Thanks for the link Jim. That may have just pushed me over to the Moki. MESC's price for the 1.80 equals Tower's best deal (with discounts) on the OS 1.60. Have you or anyone reading this thread had dealings with MESC?

I'm still a big fan of the Saito's - got the 1.80 in the Extra and a .91 in a H9 Funtana40. Love the sound and ease of handling, both are great running engines, I just need more power for the long vertical stuff. Considered gas but I just don't think the Sig Extra's wing area needs another pound of weight. Its flight characteristics are right on at its current loading with the Saito.

What brand of fuel are you guys running in the Mokis? I sure like the prospect of running of 0% nitro. With my current routines on the Saito I'm burning 32 oz. of 15% for a safe 8 min. flight - almost a gallon per session - ouch!

I also have been reading about regulators and pumps on all these engines (got a Kline on the Saito 180) - what are you having good results with?
