The Flyin' King is perfect with the 215!!!!! Not too small at all. Now I DID build wing struts for it. Easy to balance too. -Tom Three bladed prop....30x16????

I know its in previous pages but dang thats a lot of reading. What are most of you 250 owners using for prop size and pitch?

GeorgiaFlyer,

For break-in i use a 32X18 2 blade. Then on my wildcat i have a Solo 3 blade prop set at 18 degrees pitch. It works great.

Straightleg

A Biela 32x22 two blade. will give you a rpm around 4000-4200, which is very harmonic for the 250, and good pull.

Hello all of you Moki guys.
I just got my first one, a 180. I am going to ask the unthinkable question, would you use a electric starter, or always go for a hand start?
you see, I have been bitten before by smaller engines, and I need my fingers for my work

I have always hand started my 250's without the need for a starter. If you really don't like the idea of hand starting then i would recommend you get yourself a good 24volt capable electric starter.

My 250 is easy to start by hand but I have a 3 blade 32" solo prop on it and I use the biggest Sullivan starter to save blades from loosening. If you have a solid prop you can try to start by hand. Mine uses a fair amount of choke to get going. In fact it will run slow with the choke on. Using the starter is a bit scary and needs a helper to hold back the plane.

I use my Dewalt drill to start my 180. I always spin the prop a few times by hand first to make sure there is not a hydrolock on any of the cylinders .

You should be able to start it with a starter and no choke, at idle on the throttle. Be very careful if you use a starter and the choke. If you overload the cylinders, you WILL blow the head gaskets. The first start of the day, I may use the choke, but I have it on a servo and open it at the first pop.

GeorgiaFlyer

I have always started mine by hand. No issue at all. Just be careful when it is ready to start it will do so pretty easily so get your hand out of the way quickly

Bayer

Thanks for the advice on starting techniques. I will try hand starting initially, but have bought a "Miller Persuader" as a backup.

A time tested 1-2 flip technique we've used on 3 different 250s: fuel pump on, choke on, 5-6 solid flips (as in through compression), choke off, ignition on,1-2 solid flips and it's running. 80% of the time one flip is sufficient to get it running. Interesting finding, the engines are easier to start with the 3 and 4 blade carbon fiber blades versus the wood blades. More flywheel effect with the heavier blades.

Bayer, I have a large Coleman starter. It was intended for GoCarts, but reconfigured with a large Miller cup. Works perfectly on a 4-5" spinner. There are no issues with getting a hand/finger strike. I use mine on my 3W-157b2 as well as my MOKI 215, I've even used it on smaller 50-75cc single cylinder engines. I also start by hand when I'm sure the engine is in tune, and should start easily. Most of the guys at the flying field are amazed how well it works, and some make disparigising remarks. However they make other remarks when you are flipping the prop for 15-20 times, and still not running. I like the safety aspect of the starter, cause at 73, I'm not as fast as I once was--or at least thought I was. Usually, one quick push of the starter button--maybe 2-3 seconds and the engine is purring away.

Larry, Thank you for your reply. I am thinking along the same lines, because I've found that when getting to know a new engines "habits" is when I tend to get surprised/hurt. I like your remark on being fast ! I just turned 50 myself, and seems I have some time left in the hobby

One more question - I'm on the lookout for a 3 bladed prop for a Moki 180. But, there seems to be a large variation between recommendations when you look at different home pages. Does anyone have a suggestions, how does a 25*16 (3blade) sound ?

Thanks again

Depends om the prop maker. I am swinging a Biela 28x16 wot at 4000rpms and have used a 26x14 that held the same RPM

Bayer,

I have a Moki 180 radial on a Meister Corsair and flew it with the 26 X16 Solo Prop with no problem at all. I went to a 28 X16 because it looks great on the Corsair and also have no problems at all.
If you are interested, I have three 26" Solo blades for sale for a $100.00.

Rene SOLD!!!

Good Morning.
Please, anyone know the exhaust thread of the Moki VT-50?
Or anyone know if the Moki 250 radial has the same cylinder head and exhaust thread of the Moki VT-50?

Regards,

Max.

Forgive me in advance please - I'm only up to page 31 :^)

I have a 215 and am looking for more carbon fiber 3-blades to provide thrust for an Airworld Sukhoi SU-31. I purchased the Fuchs 28-18, also considering an Engel 30-16

https://www.engelmt.de/index.php/kat...300_x_160.html

...and whether they are sold here in North America.

What other options have folks tried and liked on aerobatic-type airframes?

Now...back to page 32 :^D

I have one of the original 215's from R/C Showcase that I damaged in a nose over. The engine mounting lugs are broken and the wires coming out of the front case are pulled out.
Where in the US would be a good reliable source for repair?

see you soon,
John
