Losi 5t (1.0) CY29cc Dynamite to 62cc G620PU - Help

[Losi62]

@monstertruckier15 the link you sent shipping was set for April arrival ? it has been one helluva rough intro to this hobby. I'm undeterred so far. I've rebuilt loads of two stroke dirt bikes so figured this would be straight forward, NOPE, its a whole new world!

Bought it now!




Is there like a rc crash course somewhere lol

 

[monstertruckier15]

I think that G620PU was nothing but problems for you. it needed a lot of work to put in. Better of sticking with CY or Zenoah. I have a Rovan 30.5 cc and never had problems.
If in the future you do go Zenoah make sure to get a new half clutch housing. The Cy half clutch housing is different from Zenoah. You will be asked or select if you order.

Agreed, I feel like such a fool. But now I know. Once I sell this motor I'll get something with a little more zap to it. For now I'll rebuild the CY, , thanks for your help and patience

I have a Zenoah G320 just sitting in the box for a spare.

@monste unfortunately the cylinder you found was the wrong one. I can't seem to win for losing.

 

[monstertruckier15]

Then send it back to the seller. CY did something different with the F29 engine I guess? (why discontinued?)
\Dynamite F29 Top End Rebuild Kit (4 bolt): DYNE1075 Product Reviews (rcslot.com) This should be it but out of stock or discontinued.

You could just get a new motor?

This is what I was trying to explain to you previously. You can not find a top end for it. Anyway thans for the help, I have a good idea what needs to happen from here. Take care

 

[monstertruckier15]

That's why I never bought the losi with the dynanite cy engine. It was junk from the start and more expensive as a upgrade and parts were hard to get. I waited until standard parts were available. Best of luck Either get a zenoah or a Rovan motor. Stay away fron CY.

 

[Losi62]

Yeah if you can recall the topic of this post lol I'm in this position because I was attempting to replace the motor with a zenoah (I was mislead with the wrong model) but nevertheless hahahaha

 

[monstertruckier15]

I tried. I didn't know the that the cylinder holes were different. 2 and 4 bolt are standard now so it would have worked. The cy Dynamite you have wasn't and is discontinued unless you buy a new motor. I wouldn't buy a new dynamite cy motor. Go standard. I like my Rovan 30.5 cc.

I would stop right there. From what you are describing, you are trying to install a 62cc engine into a Losi car. Bad idea! What your trying to do will just destroy the car probably. To install an engine that size you need a chassis that is metal. The only people that I know of with the necessary experience with engines this size is in the UK. They sell engines all the way up to 80cc and these engines are meant for 1/5 scale RC. Very important. They also sell the cars and parts you will need. Their website is:

look there before doing anything, please!
