I am more familiar with the rear motor as I have way more races on it, and I am not giving up on the mid yet but part of me just wants to run mod with the mid, rear in 17.5
A couple locals are doing that. Converting the mid to mod and running a second class. Kinwald is doing some local testing with Rm vs MM B5. I am hoping, that once he is done I can pick his brain. He told me that when he ran X-Factory, he always ran fans on everything, even in mod. BTW, if you ever ever get a chance to look at one of his cars up close, you will get some wood. lol. He does soooooooo many little customs things. I held his worlds centro from last year in my hand and looked it over. Its was a freaking piece of art work, lol. Anyway, he said he plans to run fans to keep the 17.5 temps down. Also, I know this sounds lame.....but if your car seems slow, find an orion r10 pro with SS firmware and try it out. I am not one to really get all wet over an esc, but I about pissed my pants when I put one in my car. I freaking swear to all that is good, that esc is a cheater esc. Something is just not right about how much power it puts out.

I just ordered a fan and plan on trying it. I put my R1 Wurks motor in the mid which is known to be a hot motor, but it likes timing, and taking the timing out really slowed the feel of the car down compared to the rear motor car. My mid is about 31kg heavier too which doesn't sound like a lot but I can feel it in the way it drives. I didn't think the mid would have the cooling issues like it does. Putting some holes in the body, and having the rear of the motor exposed (kit body) would seem like enough.

A LOT of it is how you store it. But, I was getting ready to order some of those, and a friend of mine on here, who I know takes pristine car of his stuff, said his packs arrived at his door puffed. This was in the spring, so not hot out. If you wanna talk about cheap cases, try the turnigy, lol. I tried to use aliigator clips as charge leads, because i have a mix of 4mm, 5mm and so one, and the clips cut through the case all the way to the terminal. Turnigy may have the cheapest cases on the market. SMC, protek, reedy and a few others appear to use the same cases. Venom is the only one with a really stout case. that thing is hard and thick....

31KG.....crap, is your kid riding on top of it

My big long post was eaten by rctech. Lighten the car up some, possibly cut a 1x1 inch hole in front of the motor to let air in and maybe get some cut gears. The alum topshaft, avid triad, pucks and cut gears, go a long way into giving you more power. I hate spending tons on the stock class, but my current track is very competitive, and unless you like the D main, you spend the cash or join mod. FYI, we had 39 entries for 17.5 last Wednesday night....Middle of the freaking week, lol.

Yeah, I recently came from a track that had like 3-5 entries in 17.5. Sometimes it would be just me and another guy. On the upside, I am a much better indoor driver, lol. I guess I am a traction hero

I wouldn't worry about it too much. We pumped out a few stock buggy state champs because the guys learn the changes better as they are more pronounced so when they get outdoors they know what to do quickly. The other half of it is those races almost always end up blue grooved so the bite is up and they have more experience with it.

For me its about track consistency. I can test changes and feel them more and I can hit my marks more often because the track does not drastically change through the heat. If anything, it gets better as the race goes, not worse. Anyway, it has been 105-110 outside, so the 78 deg indoor track temps are very appealing, lol. That alone make it all the money I am dumping into stock to try and stay competitive worth it, lol. We have a biggish race coming up in July, I hope to run the race as my first bigger race in a while. Heck, with 39 17.5 entries, every week feels like a big race, lol.

Just come and see me at the track for setup and how to mount fan. My mid motor 17.5 is untouchable @norcal and gives the mod guys a run for there money.

I actually like less timing on my R1 motors 69/32 with 20* timing

I know both of your cars are untouchable. I dunno what it is but I feel like my mid is "sluggish" compared to the rear motor. Not just slower, although it is a tad slower. But ya next time I see you there to check your fan out.

I started with 69/33 and 20 degrees timing, and the temps were pushing almost 180, so I went 72/33, reamed a few holes in the body and the temps were down to 160 which I am fine with, but not super happy with the performance. My rear motor freaking RIPS by comparison I feel like, but I only have 2 races on the mid, so I need much more track time.

have him take your car for a few laps and give you feedback. If his cars are untouchable, maybe yours can also be that way

The fans may become a norm for the mm and maybe somebody can make some type of adapter to put one against the plastic piece over the motor. maybe even able to use the existing screws on top of the motor brace/watherfall piece.

My B5m with all the light weight transmission upgrades and fan does feel slower then my b5 rear but lap times, consistency and how easy it is to drive fast outweighs it.

After adding pucks to my car I went back and added 20 grams with the C brass arm mount to add stability to the rear.

Yesterday I had the chance to run the super light weight shorty pack with no setup changes made. Car had the rip of my rear motor and I found myself clearing jumps way easier then with a regular shorty. Car was on edge and I was not hitting consistent lap times. The battery did have noticeable power drop off after the first few minutes. The car can be tuned around this battery but for now I love how balanced my car feels with regular shorty.

Like what Wildcat suggested.. let me drive your car and I can tell you what you need. Also feel free to try out my car.

Battery might be a problem too. I do notice a drop about 2-3 minutes in. I would love for you to drive the car and see what you think. Of course I get used to the track layout and it is changing again, so who knows how the cars will behave afterwards lol.

Personally I thought my Mid motor seemed way faster to drive then my rear motor. Took me a little bit but I am almost a full second faster with the the mid motor. Now I"m not as consistent but I am faster.
