I've had so-so experience with them so far - a 620 and a 630 have blown on me.. The other 620 is doing throttle-brake duty in the LST2..

I may just have to gut the Muggy for the winter..

Anyway, shock and diff oil??

Also, I - believe it or not - am not ALL that taken with the body... Have you guys heard of the Symbio body - for use on the Mugen or CRT?? It says it also works on the long-version Mantis, so I don't know what to make of that as to whether it would fit on the Hyper... So basically, will a body made for a Mugen fit the Hyper??

Thanks..
