like i said its all on opinion and what u like.

Well i have a 3 speed savage. I can see your point very well taken with the ni batteries. I have ran mine with limn and don't notice it at all. If it is a big concern could make it shift a little early cause the brushless would have enough umph to pull it.

I would love to see a 1/8 onroad converted, you could do a high voltage setup with 10s using small lipo cells, like these http://www.flightpower.co.uk/core/da...a_5s1p2500.htm the smaller cells fit the chassis better. I think a 1940 would be the best size motor for this conversion. I may convert one of these myself eventually.

Here are some pictures of the mugen to give an idea of how much room you have to mount a motor I am not sure you would be able to keep the mechanical brake or not, you can use the motor break no problem though. I dont know how their 2 speed works you may be able to use reverse :027: the length you have avalable for batteries is not very long, looks to be a little longer than the recever pack :002: I would convert one if I was confident it would be faster and quicker than the nitro version at least in a straight line.

Thank you for the pics and the info.
I just picked a brand new Mugen MRX3 for cheap so this will be the "test bed"!
I was looking at motors. I was thinking of a 1940/9 Motor and running that with a 8s LiPo. I am wondering what size battery can I fit in there. I wonder if I can get two 4s Lipo's in there with 2500man each. That way I can still use my charger which can only charge up to a 4s LiPo. If I am running an 8s then, the 1040/9 might not be the right choice (just thinking out loud here). Is the RPM per volt listed "no load". With a load, it may work.
Thanks for the help.
