Almost every mod car at the local track is MM and they can do wheelies all day with the traction level. But in stock, 90% of the cars are RM. Mostly for the power. MM handles just fine. I am hoping to put together a mod MM car soonish. I need a second class to run.
I have to disagree on the $$$$ part for lower weight. I have spent no money on light parts and im at 1552g rtr. Used v2 slipper and b4.2 turnbuckles and modded the car to the hartson setup.

Some people are getting to 1500 grams. Lol, I dont want to ague what is needed and what is wanted. lol. Many people beleive they need 1500 grams for stock. I dont believe that, but many do. People are buying carbon fiber motor plates, lol. That dont really displace heat like the alum one. I run my cars mostly stock with zero mods. I dont believe in mods. If the car "needs" mods, I sell it.

They will give you a store credit. But you need to ship it back

I am not saying what you said has zero validity, but there are ways around those obstacles.
Here's my setup that racenut is talking about for those that are interested.

From the R1wurks motor thread:

http://www.rctech.net/forum/electric...proved-11.html


Running 69/32 with 20* timing. Before mounting the fan in my B5m i was coming off @ 180* (no holes cut in body). With the fan I can run as long as I want and stay around 130*. With the fan my car is very consistent thru out the run and has very little fade allowing me to continue setting fast laps towards the end of my run. The fan touches the top of JC silencer body and C4.2 body. The fan is a little on the big (30mm x 15mm) side but produces 10 grams of thrust. I tried a smaller fan that clears the body with ease and that can be positioned a little more centered on the waterfall but it doesent move as much air resulting in higher temps (160* after 10 min and noticeable power drop off).

I used this mount and made a few simple modifications (dremel) to the brace to mount the fan.


R1 Fan (13.2 grams)
http://r1wurks.com/product.php?id_product=49

R1 Fan Mount (1.5 grams)
http://r1wurks.com/product.php?id_product=57

I have a few pics on how I mounted it on R1wurks thread.

You can also shave the chassis brace and mount it this way. I had a friend of mine mount it this way and it kept the motor cool but he got T-boned and the fan shattered (must have been the perfect hit). Also mounting this way requires you to cut out body to clear fan.

30x10mm fan works well for those with less aggressive gearing setups and clears top of body by 3mm. **Smaller fan also allows you to center fan on waterfall and use battery brace.

Did you drill/shave other chassis parts? MIP pucks? I run mod but was thinking of dropped a few g's here and there if it doesn't weaken the buggy.

I have mine mounted in my cut out waterfall/chassis tub. It is one of the orion fans so it pushes a ton of air, and is flush with the battery tray. It moves tons of air, and doesn't impede on the battery tray.

I run mod as well so I dont have the puck system. I have modded my chassis for the hartson inline setup. Time with a dremal will drop some weight off the car.

So here is a mod for you then! B44.2 battery hold downs....
