THE NEW MT 57CC ENGINE

[Al Lewis]

Morning Ralph! Sounds like you've got a handle on this one, as usual. The numbers posted are about what I'm turning with my DL which is good. Haven't looked at the weight or price on this one yet but I'm assuming they are comparable. Also sounds like they may be using Bakelite with the inserts cast into them for the carb block. Stuff works great but definately has a shelf life if subjected to any heat, as I'm sure you know. Melamine phenolic would be awesome there. I'm with you on the prop bolts. I've found that the 6 bolt patterns offer too much opportunity to strip out one. I just wish these guys would discover the 10-32. I know it's only .012" difference but when you measure the thread depth on a bolt that size .012" is a lot. A heli-coiled hub would be really nice. Well good luck with your new engine buddy. Sounds like Tomy may have finally found a winner. Do you happen to know if they are using A390 alloy to cast the cylinders??

The first DL I tested here turned a Xoar 23-8 about 6700 with the factory muffler...
I broke that prop but have a JXF 23-8 to test the MT with..
I don't know what the alloy is, Tomy probably doesn't know either...The MT62 looks very good, if the alloy is the same it will be fine....
Wish Larry would send me the engine...

[Al Lewis]

I wish he would too! I'm dying to see what your test results are.

Iain Nichol who is the UK Distributor www.iadmodeldesigns.co.uk
Is hopefully testing the other uk MT57 prototype out this weekend,hes done a smashing conversion to an AEROWORKS PYTHON to enable a JMB Cannister to be fitted.Hopefully a Video will follow

Should be a killer with a pipe or tuned canister....Check out the G62 results at the top of the page...The MT should outdo those numbers....8400 with a 22A prop..

Top of what page Ralph??

[rcign]

first page of the gas engine forum, at the top...
Sticky, real world rpm...
How come they call it a "sticky" ???

[RTK]

Thanks Ralph. I am thinking of piping that 62 I sent you. I might want a little more poop from her in my next plane.

I thought that the MT57 was turning a 24-8 in the high 6000 range ? These numbers we're talking here seem to be in line with my DL50. And I expect to reach 7100 minimum on a 23A Vess when I get a chance to work it some.

Looking foward to you getting the engine Ralph. Larry SEND HIM the engine !!

Hey guys, I myself dont even have one to please customers!!!!!!! Ralph will get the first one of the litter. Tomy aired me one and soarich cried so hard that I had one and he did'nt so I had to give that one up or loose a flying buddy. Today I get a message on the machine I WANT ANOTHER MT 57 , now thats what I call having mucho GALL!!!! Thats like crying I'm hungry with a loaf of bread under each arm!!!!!
Only kidding Rich, he works very hard to test for me and deserves anthing I can do for him. Now I hope the "OLD COOT" in Arizona dont get on my case. I would hate to loose my greatest asset to my network of good people. I guess there are 30+ other people counting the days until they get there's. I hope the plane from
China dont run out of gassssssssssssssssssssss.

Ralph

The carb bolts pass through a carb adapter plate, then through the reed cage, then thread into the back of the crankcase, all compression loads on the plastic induction parts, very cool. I want another one, but I understand I'm at the back of the line now that I already got one, but this line streaches around the block, it's like the opening night of a Bush bashing movie in NYC.

Good, no need to change it...Tomy is doing it right...

Rich, do the standoffs bolt from each side, or is it a through bolt?

[joe barrington]

Hi JrJohn,the Standoffs bolt directly to the crankcase studs that protrude to the rear of the case,they r also slotted to enable an adjustable wrench to tighten them up.

Personally i think there 2 long by 3/4'' for most planes.See my pics on page 1 of this thread with a ruler in photo

[soarrich]

99% sure it's through bolted, that is how the MT50 is done. Larry gave it to me with the standoffs on, it was in my plane the next morning ready to fly, then it blew 20mph until the weekend and I don't fly on weekends. I'll have a flight report tomorrow I hope!
