In fact after the 2nd qualifier only one nitro car was qualified faster than the MGT7 ECO and it was a MGT7 nitro car.
The instructions didnt give me or 3 or 4 of my other friends problems which also have this kit. We all still consider our MGT7 perfect cars.

Although I have heard complaints about the stock motor mount not allowing many pinion size options when using the stock diff and 44ish tooth spur gear. This can be alleviated by using a center spool and much smaller spur gear. Im using a 29t spur gear.

Great, then we can agree to disagree. I don't think I would have had any problems with this kit if I had built a Mugen kit before or for that matter any other car where the center diff case was different than the F/R diffs. However, my RC8, RC8.2, Tekno SCT410, and Team C Truggy - all have the same diff cases F/C/R and the MGT7 diff cases look similar enough to not think they are all the same too. Funny the people at my LHS who had Mugens all knew that the center diff case was different. Must be a Mugen thing - as a logistican I would never design a unique part unless there was a really good performance justification for doing so.

BTW correction my car did come with 300K diff oil, not 600K. I must have been thinking of one of the other setups I looked at.

Since my kit is new, I probably ahve the new motor mount in my car. I have a 19T pinion with the 44T spur and there is plenty of room for a much bigger pinon (probably another 5 teeth or so), which I doubt I'll need for on road racing. However, I'm not trying to go 140 MPH with an 8s battery like tc4basher - after all this is an onroad car intendd for on road racing.

I did some testing in the driveway tonight to get the ESC setup for hopefully some test runs tomorrow on the track.

The car will turn in less agressively, but pull out of the corner better.

If you think of a spool as just a diff with very very thick oil, then you can get a perspective of the tuning options available with the center diff. Here is a summary of what the Hudy Tuning Guide says: With thicker oil, you get better the acceleration, better onpower steering and better 4WD effect but it's can be a handfull to drive espically with a big motor. With thinner diff oil, the Front wheels tend to unload under acceleration (not good), you get better off power steering (but less on power steering) and the car is easier to drive. So depending on your driving skill level, and what your car is doing on a particular track, you might want a really stiff center diff with thick oil (aka spool) or a center diff with thinner diff oil.

A 1717 at about 48mm diameter is the largest you can fit diameter wise. Lengthwise, a 4.5 inch long motor is max.

I looked on RCmonster forever last night and couldn't find it, I'd like to have that one just because I ordered their motor mount. If you have a second could you post a link to it ? Thanks

I would go with a Poseidon 1515 2200kv. Fast on 6s,7s, and 8s if you are careful. Only $110.

Ok guys I bought the RCmonster Motor mount to run bigger gearing in my MGT7. Now the diff mount is much shorter than the motor mount. Can anyone tell me what I need to buy to get this to work? Thanks
