Please clarify!

Hughes,i used a header off a Evolution 58,Mvvs 58.i just had to egg shape the holes toward the pipe a 1/16 each, both had the same port size.
mine 57 is on the shelf for now,i just miss the power of that 58gx2.7550 with a 24-8 Biela
i guess i am looking for that sub 4 lb. engine that swings a prop like a 60cc.

Thanks guys, a couple of different options.

Hopefully Tomy and his sellers will adopt equal priorities for existing and new customers. I guess they already got my money, no sense wasting time on me! Definition of flyby night, thanks again!

We were able to record a test flight using a LS Pro MT57 on a BME Edge. This is a first generation airplane and is heavier than the newer versions. This particular plane was weighed after the flight in the video clip below. It still had almost a full tank of fuel after the flight. The plane with the remaining fuel weighed 20lbs 7oz. (The plane weighs about 18lbs 9oz DRY).

The clip is not that great (I wish my camera skills were better), and the weather was not the best as it started to rain just after take off.

The clip shows the power to pull this plane vertical right from take off.
The engine in this plane is not the same as the engine I described in past posts, it is my 2nd test engine -at the time of this flight it had about 30ozs of fuel through it, but it is setup the same as the 1st test engine with a stock muffler.
Here's the clip:

Sounds good from here Little noisy but seems to not be lacking on power. What prop was on it for that flight?

I will figure out a way to make a single bolt conversion available, since I will be doing the service work for Larry.....

Hello RC Ign,
I have a single prop adapter shaft for the DL 50,May also fit DA 50,and maybe the MT 57.
I will send you one.

Can someone please tell me what the stock needle settings are for the MT-57? I live at sea level if that matters. Also has anyone else had any interference problems with their ignition? i have tried everything I can but I am still getting interference when the motor is running.

Push real hard on the spark plug cap to get it all the way down on the hex of the plug, that should fix it.

I'm going to check the needles and get back to you.

I'm also at sea level, L 1 3/4, H 1 7/8 are my needle settings.

Try starting the engine then open the throttle to get 3500rpm, with the motor running turn the L needle in it should speed up, use the throttle to bring it back to 3500 rpm, keep doing that until you see no change in the speed. The L needle is now slightly lean, turn it back out about 3/16 of a turn. Now try popping the throttle open from about 2200 rpm the motor should speed right up, if it dies turn the L needle out a 1/16th of a turn and repeat until it speeds right up. If it stumbles when you pop the throttle open it's rich, trun the L needle in 1/16th of a turn and repeat until it speeds right up.

Now open the throttle all the way and turn the H needle in until you get maximum rpm, leave it there don't back it out. Fly it like that and if the motor sags in long climbs trun the neele out 1/8th of a turn.

You playing Ralph now Rich?

[tomyrcmodels]

use header and canister muffler or or pitts muffler are able to reduce the noise and get fast respond at low and mid ring

I finally got a chance to finish my Lanier Stinger. First run of the MT57 tomorrow and maiden flight. This engine sure has alot of compression for not being run yet...not that it means anything, but it is nice to see.
