I am waiting for my Moki 180 to arrive and i am starting to think it might go into my WM Extra 300s 160 - Inverted?
It suggests to put it on an angle - but as i am buying a Pitts muffler - I wont be doing this - I keep thinking that hanging it on its
side will make the plane laterally unbalanced quite a bit - its a big engine!! What are the Pros and Cons??? I can get mufflers to fit both options - so thats no
biggie - Who else has hung there big 2 stroke up side down??

I used the MOKI 1.8 in my midwest Extra 300. It works better at 90 degrees to the right. The Bisson Pitts muffler workd perfectly with this configuration. The muffler actually serves to counteract any imbalance that might result from the cylinder being offset to the right. One thing to remember, the balance moment is so short that you would not notice a minor weight shift (axially) and you can shift the airborne battery pack to the left side of the fuse to do the final balance. The Extra's cowl desigh lends itself better to side mounting the engine than to invert the engine. With my Extra, I only had to cut a small hole for the glow ignitor (could have used on-board glow and eliminitaded this hole, and one for the needle valve. I did have to cut the opening for the exhaust tubes, and made it a little larger than required for cooling exhaust.

Trust me on this, you will not regret mounting the engine in this manner. The Moke 1.8 is a real powerhouse, and the Extra loves it.

I have an inverted Moki 210 /Pitts muffler in my Cap. At first, it was a bear to break in. After going to a Merlin plug, everything smoothed out Now it runs fine. I would suggest using a remote igniter, as the hot exhaust gasses will get you if you're not careful. I see no need for an onboard glow unit. The Moki runs great without it.

I have one inverted and a BGX3500. No issues at all because i also lowered the fuel tank.

Ok,

Thanks Heaps everyone,
I recieved it today, it looks grunty just sitting there!!!!! I think i will mount it on its side, it will work out a little better, my last ASP 91 was on its side and it was so easy to use - Thanks again, I will post some pics soon!!!


Cheers

Ok,

So i went woth the 90deg option, looks and fits bang on!! Cowling is yet to go on, but have tried it and nothing touches, although i will add some cooling exits i think!
Muffler has yet to be choosen! I am thinking a smoke system is in order so i will look into that also - RCDON.com has a smoke system on his 210 Moki and that looks unreal!
