Hi Guys:


The rumors about this engine from TMM (formerly 3mm but 3M objected) have been knocking around for a year. I am happy to announce that the engine lives, it's real, and I have one (actually I have two).

This is a 2 cylinder boxer style engine of 106cc. It is similar in layout to the newer style DA-100 but it is definitely different. TMM cast a whole new cylinder, they did not use the DA copies that are used by almost everybody else and they did not even use the old TOC-53 cylinders. The design is all new which is clear once you look at it.

I have not yet run it, I'm putting it on a new plane that will be done in a day or two, I hope to fly the combo later this week.

The engine comes with the proven Rcexl ignition and a beautiful set of polished mufflers. Exhaust options also include canister mufflers in 2 sizes and headers in 3 drops (25, 50, and 75mm). I believe it has the same 42x35mm bore/stroke as the TOC-53, it has two-ring pistons and uses a genuine Walbro carburetor.

The weight bare is 4 lbs. 15 oz. including the carburetor. This does not include spark plugs, prop washer/bolts, mufflers or ignition. I believe the all up weight will be about 3/4 pound lighter than a DA-100, but I cannot confirm anything right now except the bare weight.

As I said, I have two engines now. They have already been through rigorous testing at the factory, but these two engines will fly for several hours before I go further, then I expect to have inventory available for sale in about a month.

My understanding is that the engine turns a 27-10 JXF/Xoar prop above 6500 rpm, but I will do verification testing.

The price will be under $800 complete. Canisters will be available for $200 for a set of two including headers, couplers, clamps and the muffler.

Wish I had the time to have had the second one for testing. Keep us informed.

Have you got some 3 views w/ dimensions so a designer can check out the fit in his designs?

Tom, please do me a favour and measure the bolthole spacing for the mufflers. I need two new mufflers for my Brison 6.4. I like those polished mufflers[sm=tongue_smile.gif]
Thanks for your help, Tom

rctom

36mm, just like the 53.

For 3 views use a DA-100 as worst case. The length is the same, width is less by maybe 1/4". If a DA or DL-100 will fit the TMM-106 will fit too.

Thanks a lot, Tom. Now I need to measure the distance on my Brison and if it's (hopefully) the same, I would like to order a set from you.

The bolt hole spacing on your 6.4 should be 35mm. I have a 53 muffler here and it looks like you could oval the mounting holes enough to make the new mufflers fit on the Brison 6.4.

Looks very nice Tom.

thevirginian

Thanks, Truckracer
Yes, if it's not more than a millimeter than I can easily elongate the holes to make it fit/

thevirginian

Tom, is it too early to ask how much a set of those muflers would cost me?

Do you have pricing on this engine with cannisters?

I haven't decided on a final price yet, but I am sure that it will be under $1,000 with all the canisters and everything. I may be able to give a small credit if someone doesn't want the mufflers. Figure $900 with canisters but without mufflers.

We have found that the TMM (3MM)engines are absolutely brilliant
Flawless running.
Have a 106cc, 4 x 53cc and getting another 106i shortly.
Just wish they were marketed better, they certainly are a top quality product.
Cheers

Hi Tom F, are you having the headers and cans made or are they coming from the TMM factory?

thread is almost a year old, any updates on this beast?

rctom

The headers come from TMM and are relatively soft. At least two of them have blown out at the turn where the hot gas first hits the side of the pipe. To date I do not have a good solution for the header dilemma.

TMM does have canisters but I prefer the cans that I get from another source because they fit in my planes better. The TMM cans are long and skinny.

TMM went back to the drawing board and designed a new cylinder and piston for the 106. I have 3 sets of them and will be retrofitting a few engines in the coming days. They claim big power gains, we'll see what happens soone.

Hi Tom, well since my last post I've been busy talking to Chen at TMM about his engines and stuff and he said the headers they have now are good, So I now have a new version 106 with 65mm headers and canisters for my 35% Yak and it is a beauty of an engine and I also just ordered the new revised 53(with 65mm header and canister)that is guaranteed to have more power than the old one Chen told me, it will be going in a 29% Sback from Pilot-RC. These will be my two planes for testing the engines as I will be the Canada(Only) distributor for TMM Engines.

rctom

I hope it all works out for you. He told me the headers were good too.

Please let us know if all this stuff hold up.

I hope so to, but if it doesn't then I guess we'll be on to the next adventure. I will be receiving my 35% Yak and 29% Sbach at the end of February so hopefully I will get them both ready to fly for the spring and I'll let you know how the engines and exhausts work out.

Hi Ed
We lookforward your test report,I think TMM will not make you disapoint!!!!!!!

Hi Chen, I received the TMM 106 (still waiting for the 53)and by looking at the engine I know I won't be disappointed. My planes (from Pilot-RC which I'm buying through Paragon RC here in Ontario)for testing should be here by the end of February so I'm hoping to have some reports by early spring as long as the weather cooperates. I'm building a new shop so if I get it done in time and heated I'll run the engines up to see what there capable of.
