Last night the track was more accepting of a low pin Dirtweb/Chainlink/Electron of which I used the Electron.

The results so far are a mixed bag. On the positive note the car definitely has a lot more forward bite. That problem appears to be solved nicely. The problem is now that the car is very loose off power coming into a corner and in mid corner such that it wants to over-rotate. The car now needs some more side bite. This is due to the increased weight forward and that any braking will want to pitch the car forward more than before because of the new motor position.

Here is how I tried to tune this out in the order I tried them in:

- Reduce drag brake to 5% (Probably should have went to 0)
- 0 degrees anti-squat
- Went to the LCG battery after starting with a shorty lipo of typical weight
- Took the 60g saved from the battery and put 14g on both back corners of the chassis and another 30g under the trans housings
- Went to the middle mounting hole on the rear arms in a quick effort to reduce droop

After all of this the car was almost there. Still a little loose going into the corner and at mid corner. Enough to bother me. I did have some fast laps mixed in with some inconsistency due to the unpredictable behavior off power. Going to the lighter battery helped and adding the weight helped even more. I was actually quite surprised by how much changing the rear arm mount helped. I have attached the setup I ended up with.

The next time I go out I think I am going to put limiters in the rear shocks and go back to the outer hole because clearly anything to keep the weight from shifting forward is helping. I also will go to the black springs in front (4.0 rate) and maybe even go up to 500-550 cSt oil. I may also try to run a little less aggressive tire in front like a AKA Pinstripe or a JC Barcode to take away some of the bite in the front. And finally get rid of all drag brake. If that all doesn't do it then I might try the LRP super shorty and put the speedo next to it to get even more weight off the front.

The last thing I ended up doing but not on the car setup itself was to go to -25% expo on the steering. I might even go to -50%. This car has TONS of steering and I feel like if I can just use the first 50% of it most of the time then it should be easier to handle it. I really feel that this car could be seriously dangerous in the right hands. I would put myself at roughly average in terms of skill as that is where I end up finishing at club races. But there about 6 guys competing at the ROAR 1/10 off road nationals who race at my track on a weekly basis so keep that in mind. But with a little more setup work and some practice I think it is going to ultimately pay off.

For those looking for a more conservative and cost effective platform for tracks you typically find here in the States by all means go with the SV2 and follow Tony's recipe for lengthening it. That or wait for an updated SV2, which Tony has stated earlier in this thread (or maybe another Schumacher thread) would be updated. But if you run on tracks that trend towards the mid to higher levels of traction I think this is your ticket.

Hopefully Tony gets the setup info from the team out at Euros at some point and we can see what they are up to with tuning the MM conversion. And please everyone else share what your experiences are if and when you get the conversion done.
