ok, so I completed my first night with my MM converted car. The only upgrades I ran were traxxas xrings, 2 Ti turnbuckles and an AVID triad slipper. I ending up running a total of about 7 packs at about 5 -6 minutes each. This includes 2 heats and a main. We had 34 drivers in 17.5 buggy and I qualified 12th. But now lets get to numbers. RM vs MM.
Best run of 17.5 with RM
16 laps 5:20.6
Fast lap 19.01
Top 5 19.242
Top 10 19.452
Top 15 19.815
Best run of MM on same layout
15 laps 5:00.551
Fast lap 19.043
Top 5 19.376
Top 10 19.606
Top 15 20.037
Conclusion. I am still faster with the RM car in 17.5. I was really surprised that my times were not better, because the MM car "felt" faster and "better". I probably was losing some time in the single short run up double and I occasionally slapped and slid the car over a big double. But in other parts of the track, the car felt much better. Also, this layout has a lot of 180's, so the thing that the MM is supposed to be really good at, didnt exist. If the track was more flowing, I am sure the MM would come out on top. I also only have a few packs on the MM and probably close to 100 on the rm. Also, my MM car weighted in at 1650 grams and my RM car is 1525. But, I am not sure I would ever want the MM car at 1525. Probably 1575 -1590 would be a weight. The MM car was definitely looser in the rear, but I think the weight made the car more stuck. And it still felt pretty nimble. And I really really need to find out what Spencer Rivkin is running for a shock packs. He was long jumping, and flat landing, rear landing, front landing and side landing the big air jump and hit car made no sound at all landing it. And it was not because he was fast, we landed that thing every which way but loose and it landed like a cat. Pretty much every other b5m slapped and bounced trying that. I did ask one AE driver what shock package he was running.....He told me he didnt know, Spencer did his shocks....rofl. Anyway, summery... I really liked the MM car, but IMO its way too heavy for 17.5 indoor medium bite at stock weight.

I was faster with my RM vs the MM as well at first. I thought I made a huge mistake with the MM. After about a month of fine tuning I am now faster on the same track with the MM by a pretty good amount of time, and I still have room to improve. Summer is dead for indoor around here usually less that 10 cars in 17.5. I use this time to try new stuff. With the car all stock and a shorty pack I was weighing 1642g. I put Schelle slipper, aluminum top shaft, aluminum screw kit on it. Still a little heavy, but some of the weight I saved I put it back on with aluminum hubs and a few other things. It's now around 1580. I set fast lap time last night so I am where I need to be now I think. I think with MM you have to give it a little more time to fine tune, which really frustrated me at first. I feel good about sticking with MM into the fall when the season starts again.

It was a much better experience than when I tried MM outdoors. I am going outdoors this weekend, but not really sure I want to get my car filthy running it on the track, lol.

Side note: Why the hell does indoor season die in the summer? Its 110+ degrees here, I have no desire top be outdoors.
Side Side Note: SRS is opening indoors next week. And they "copies" the dirt mix from WCRC. So its going to be a higher bite indoor clay track. They have a grand opening race weekend coming up, if you can make the drive you should.

Yeah, the "felt" good. Less squarish in the corners. I just need to figure out how to take better advantage of MM. I am sure i was driving it just like I do my RM car, lol. In fact....Aside from the shock package....I left the RM setup on the car when I converted it to MM It was a much better experience than when I tried MM outdoors. I am going outdoors this weekend, but not really sure I want to get my car filthy running it on the track, lol.

Oh and about the jumping... in the words of the great Mike Gay.... "that's what downsides are for"

I have a b5m and I'm wanting to try the flat arms, and my hobby shop doesn't have the b5 front tower yet, but does have a jconcepts Carbon fiber front tower for b4.

We dont have AC here indoor either...we have swamp coolers, lol. I guess they are much cheaper to use than AC, but they add a bunch of humidity.Bob, your a funny guy, lol. I do downside jumps. We have a single double, but if you pull up to down side the single, you lose too much time. I just had to work on how far to jump, so I had enough run up in the double. I pretty much got all of the jumps figured out in practice.
Also, my last couple laps were 21's because.....some guys was weaving back and forth in the rythm section, so i had to pull up and pick the right time to pass, so I made a clean pass, but last time. And the last lap, I knew i was close to a 16 lap run and was pushing it and i freaking had it, but a guy crashed on the last corner before the straight, so I say this and adjusted my line, but the turn marshal run into the turn and flip the guy, so I had to take a really wide line to avoid the marshal. And of course the guy got flipped as I was going buy and I had to dodge him as I raced to the line. I easily lost the .5 seconds I needed for a 16 laps run in the last corner. That best run I had with the RM car was pretty much flawless. No one got in my way and I was able to hammer out clean laps. So I definitely think I will be faster over all with the MM car.

The B4 tower "may" be good or bad, who knows. Personally, I like to keep the same generation parts on a car. If you put the B4 tower on and the b5 flat arms, and decide its crap. Is it because of the flat arms or the B4 tower.. And asking people on here for advice, with be and apples and oranges kind of deal. Because they are probably running the B5 front tower.
