First of all, Andy.....this is a GREAT forum of a very interesting topic. I commend you for choosing it and putting sooooooooo much R&D into it. If I had the time and money....I'd be doing some research myself(more on that later).

The Associated Mini MGT 3.0 is what I am working with......seen here.

I have the original MGT.....but want to go with a small one because of my track that I have is smaller. I, too, have a problem getting Nitro fuel because of my location and that is my interest in diesel power. According to Mr. Davis in our phone call.....the engine in this truck is, " most likely Thunder Tiger......made in Tiawan. Which, of course, means it is junk". Then he tried to tell me that Associated had been bought out by a foreign company. Last I knew they were still in California. I do not know the facts....but that doesn't seem right with me. Especially after the OS engine story he gave me. He also kept telling me that, " we do not make, nor will we ever, make a .12 diesel conversion". I kept saying," Great.....cause the engine in this truck is a .18 size". He still kept telling me he couldn't help me with my, " .12 sized engine". ???!!!!

Seems since I've posted on this forum about Bob Davis.......I've gotten a surprising amount of IMs from several people about having the same problems. So.....he is a pioneer.....that we all can agree on. But, I think it's safe to say he's not very good with customer service when things "go bad". I mean, hey.......even I admit.....diesel is NOT for everybody......at least, not yet.
