Hi 72.


lot lot parts for MT70 .so dont worry about the parts if you need some, and I let one big company that have ISO9000 to build my UPDATE engine , and I test run each of them for make sure engine are good and powerful . this the new way for me to do the engine, I think better do the job what I'm good with , it's only for design and marketing , he he.

Sorry to bring you down Tommy but ISO9000 doesn't equal quality. It equals consistency. If there is a flaw that means there all flawed./ but I am probably wrong I hope.

I need a source for a y-header or a suitable type of muffler(s) as this thing is WAY to loud! Any help would be greatly appreciated, Thanks, Brian blloyd@wi.rr.com

Status: offline 		i guess im still here for the entertainment value,,i was kinda  thinking the next post would be regarding the latest mt70 offering..and all its associated issues,,but i guess that never came to light,  because the promised, new engine ,,never appeared ,im glad to see my mt70 is still running and in one piece,,that could also be attributed to having valley view  re do the thing,,, but also is because other things in life dosent give me flying time. one must remember in most cases good deals turn into big agravation with the good deal ,to be honest a good running mt 70 with bugs removed ,,is  a value,,so for those who are inheriting or buying mt engines ,,i can only wish you good luck,,,,,.based upon this thread youll need it.

Status: offline 		I have seen them up close but have no personal experience actually running the MLD 70 Twin. I do however have some experience with running the MLD 35cc Single from which it is derived. The MLD 35cc Single is quite a good engine and is the most powerful in the "Chinese 35cc" class that I have experienced. There is no reason to think the 70 twin would be different.

Perhaps Ralph will chime in on the 70 Twin, I know he was similarly impressed with the 35 Single as I was.

Status: offline 		The CRRC 55cc twin is putting out great power with less weight than the 70cc twins. I am swinging a 23x8 on mine and it will 3d my 16 pound 89" MXSR..

Weight on a postal scale including standoff's/bolts/igniton/mufflers is 3 lbs 11.9 ounces. Not bad considering only a 6-8 weight gain over the popular singles. pLUS IT IS much SMOOTHER RUNNING WITH LESS VIBRATION. hAS A WALBRO CARB AND HAS NO DEAD SPOTS THROUGHOUT THE THROTTLE RANGE!

What a pitiful shame,,,, this is a mt70 thread and what are we all talking about?? other  engines made by other people  ,other than mt ,,i can now say with experience ,and having been educated ,,,that if any of the manufacturers follow mr shen ,in how they do buisness ,,they may want to stop now,,if a manufacturer makes a  powerful  decently  weighted engine for 50cc class planes with q.c. and good service ,,it will be in great demand,,,,,,,,tommy had the bird in his hand and let it fly away.  the mt70cc  engine in essence is great,,bring it back correctly and it will sell,and be liked as well.

Ain't that a fact. most of the 57's I dealt with are still being used and are still quite strong engines. They all got stripped, inspected and reassembled by me first though. A fair few bits got rejected in that process but to give Tomy his due, he did look after me with parts when requested.

I wish he would go and use his "design talents" and work alongside DLE or GP for the production side of things. The resulting lineup would be pretty impressive I think.

Status: offline 		I agree. Tomy's designs were very nice, the 57,80 and 70. It was the QC at the assembly stage where it all fell apart. The 57 I owned is still running strong albeit with the new redesigned crankcase. They have very high torque and were happiest with a 23x8 or larger prop on them. It never spun overly impressive numbers on the ground but in the air it would shine and put the DLE55 to shame and out pull it all to heck.
