Thanks, Marty. I hope I actually get to run and fly this one.
I was thinking about "our" MVVS 2.15 gas engine. Did you ever get it
straightened out? Or am I thinking of someone else?
Right now simplicity (glow) is what I have been focusing on.
I did buy that Spektrum DX-7. If it works as described, that could be an
answer to all of the spark noise problems that some folks have these days.
It has been too windy around these parts to even think of flying. Then
again, it is March.

Our 2.15 MVVS is doing well in a GP Wagstaff Extra 300.
It doesn't have unlimited vertical.
It starts and runs well.
The problem children are my 1.6 MVVS engines. It seems
that our high-octane fuel isn't high enough to make them
happy. I done blowed one up, broke one in a crash, and
am hoping that the third will do better on 100 octane
It was 0 F here yesterday with sub-zero windchills.
Public schools were closed. Today it's warmed up
to 9 F. ;o)
I'm sorry to hear that about your MVVS 1.6 gas engines.
This is probably a ridiculous question, in view of your thorough engine
knowledge, but have you tried adding shims under the cylinder head to reduce
the compression ratio? Or perhaps used an after market octane booster? You
probably have - but you never know.
Someone else asked where I bought the Moki 2.10 in another thread. I bought
It took a little over a week for it to arrive after placing the order.
This is the first time that I have ever had a Moki engine in my hands. I am
thoroughly impressed with the fit and finish. I had no idea that they were
this nice in appearance and feel.
You gave me the idea of where to put my new Moki 2.10. While I was thinking
of putting it in the CMP CAP 232, you reminded me of the NIB Wagstaff Extra
(GP) that I have, which would utilize this engine's extra power perfectly. I
have other engines that I can use in the CMP CAP 232 (ST G2300 or an ASP

If the 100 octane aviation fuel doesn't work,
that'll be my next step. I've written Pé
and he's got shims available--along with
a boatload of other replacement parts for
the inside of the engine (crankshaft,
con rod, & bearing).
There is an Ignition throttle isolator available that makes throttle
installation simple as the servo goes right next to the engine and connects
to the radio via optical fiber. Look on e-Bay under Ignition Throttle
I have been flying one for about 2 years after some extensive testing.

The bearing in the con rod failed.
I probably ruined the crankshaft, too. I don't have the
tools to check roundness, so I'll probably have to buy
one to make sure that I don't ruin the new con rod &
Ran a lot of metal through the engine.
I shouldn't 'a' done that. :o(
But I found out what was making the funny noises. :-O
