I have mine at a track today. Its a large track designed for 5th scales. My car handled like a dream. Lipo had plenty of juice for nice long run time, even with 15T motor. My experience with the M04 is that, you need a light trigger finger. From 25% to 50% is really sensitive and will cause rear wheels to break free and spin the car. When you ease gently past 50%, you can floor it and watch it dart by at full speed.
Initially I thought this was because of my 15T motor, so I tested it with black can and had same result. To minimise the effect, I added some lead weights to the rear bumper. Now my car is really balanced.

M04L and Brushless at match made in heaven. I decided to pull the Novak XRS and Reedy Flash 15 out of my M04 and went for a Novak XBR sport with EXS 13.5.
The smooth acceleration of the Brushless motor made driving the M04 a dream. With the brushed motor, I had to use a feather touch to get the car past 40% throttle. Some will argue its because of the 15T Reedy. However I tested the car with the black can and I had the same issue. If I went too fast to 40% the rear tires would light up and the car would do a 180. I tried reducing throttle speed in radio.. made no difference.
The 13.5 Brushless was smooth as silk, linear acceleration really makes a difference. I pulled the trigger to 50% without problem. The 13.5 is about a 27T brushed, so I don't have the top I used to... it's a trade off I am willing to take for a M04 that is dead on!

I don't currently have one (although I'm seriously tempted!) but our local club has a VERY robust mini racing scene and a number of guys run M-04's.
On bigger, more sweeping tracks the M-04's are the class of the field but on tighter, more technical tracks they don't really have an advantage.
Cheers,
Mike

As part of the club that Mike was referring to, we have a strong compliment of M04's in the A-main every week. I ran one for about a year, where it was a tough car to beat (replaced with an M05). They can be made to work on any type of track, but do require more finesse with setup than the M03 and M05. I ran mine with RP36's (55D) with firm inserts, blue front springs and yellow or red rears depending on available grip. The biggest downfall with the M04, is dealing with changing traction levels on the track through the racing day. As the track grooves up and grip level increases, the M04 tends towards oversteer, which makes for a difficult drive. This can be solved with going to harder compound tires in the front, or using less traction compound on the front as the day progresses. Just follow the simple rule - "slide the front, stick the rear", and you will be fine. Get the rear end planted, and then slowly work towards increasing front grip to find a balance.

Mine's only half built but when finished it's going to be a beast with 3.5T BL + 2S 30C LiPo.

I've been used to running my M04 with GP3300's and 2400NiCD packs with no issues.
Now that I have a lipo pack that's 130g lighter, does it work just as well, or do I need to add weight?
I'm running it on carpet in a month, but have no time to practice at the track till the event.. Just want to be prepared.
