Default Moki 2.1 Engine


I have no experience of this engine but am considering it for a TFlite Mustang giant scale

Apparently they work well and fit the above model

Any tips on use and starting would be gratefully received

Thanks MIkee

They're great engines with gobs of power but very thirsty. Don't use more than 10% nitro and be sure to use muffler pressure. They start easily with a back flip after being sure that it's properly primed. I check this by feeling for a bump while holding the prop through a partial revolution. Mitch

The Moki's are great motors. They require some patience to get broken in, after break in they start and run great. Just as Mitch said, once it is good and wet a bump back against compression and it is running. Do NOT use over 5% nitro (actually 0% is ok) and use large fuel line. They do use a lot of fuel but no more than any other large glow motor in their size range. An on board glow is helpful too especially for the break in period, it will help avoid dead stick landings. I initially used a Cline valve, I am not sure it was absolutely needed and have since removed it.

Hi,

Many thanks for your advice - I take it that even a powerful electic starter cannot be used?

I have ainjured hand so ease of starting is very important

What size fuel tank would you recommend?

Look forward to your reply

Mikee

I have a new Moki 1.6 in a Cap232 I plan to fly the heck out of this year. Oh, and speaking of drinking fuel........how much glow fuel do you think will flow through this.. http://cgi.ebay.com/Moki-60-cc-Twin-...QQcmdZViewItem

Sure, you can use an electric starter. The point was that it will start easily by "bumping" against compression. I would suggest a 32 ounce tank if you can fit that large of one in your plane. If not, go with the largest that will fit.

A friend has a TF P-51 with the 210, a much better performer than with the US 41 gas engine he had. He uses the big Sullivan starter on 24 volts but made up a large aluminium cup for the front of it to suit the big P-51 spinner. He has a blue rubber insert in the cup, I think it's from one of those geared starters. - John.

I have several Moki's and love them all but they are a bit thirsty. I run all of mine on zero nitro, mix my own fuel (Methanol and Klotz oil) using an OS "F" plug. They really don't need the nitro and that saves a bit of cash.

If you prime the engine wet then give a slight flick back against compression the Moki will start easily. The Dave Patrick Moki will handle 10%. Older versions would use 0-5% fuel. I try to use one fuel for all which is 10% so I sold my Moki even though it’s a great motor. Use large fuel tubing or med with the Cline. The Cline works great also. If you have tank placement issues then go with the Cline. Follow the long break in procedure exactly and you will have a fine engine, one of the best!
