They make (made) different ones for Kyosho, AE, and Losi. Checking at Tower, looks like they have discontinued all but the yellow Kyosho, is that what you ordered? Assuming the AKA's are the same measurements as the OEM Kyosho front rims, they should work great.
Since I am coming from a ZX5 and have quite a bit of mounted tires left, I measured a set of rims and compared them to the included rims with the kit. I found that using ZX5 fronts will increase absolute width (outside rim face to outside rim face) 1mm and will decrease mid tire to mid tire width by .6mm. This is because even though the backspacing is deeper, the width of the rim is also more.
The rear ZX5 rims are interestingly 0.7mm narrower, but the backspacing is also 0.7mm less, so the absolute width is unchanged and the mid tire to mid tire width is increased 0.6mm.
I had to take a body reamer to the rear tire's axle holes and remove a little bit of material to fit the larger axle of the D413. I will use my ZX5 rims without a second thought!

Awesome , I feel much better now. And yes I got the 3pak of kyo wheels in yellow since all the white rims were discontinued. So I'm glad I bought these based on your stats. Thx for the reply

Hey e-Revo - how are you liking the tekin rsx, I am going to be installing that esc with a tekin 6.5 and a 23 pinion, would I need to add boost and timming or would it be fine just like that with no boost or timming . Asking because of all the heat issues peeps are having .
The rep at Tekin converted the "turn" rating on their Redline Gen2 motors to "kv" ratings for me over the phone.
Tekin Redline Gen2 "turn" to "kv" conversion (per Tekin rep)
6.5t = 6700kv
7.5t = 6100kv
8.5t = 5300kv
9.5t = 4900kv
10.5t = 4500kv
13.5t = 3500kv
17.5t = 2500kv
From what I hear, every manufacturer uses different methods to figure "turn" & "kv" ratings. So trying to use this conversion for a brand that is NOT Tekin, will probably not be accurate.
I've also noticed a couple guys using 6.5t motors on this thread trying to gear down as much as possible because of heat. I believe the smallest pinion they have been able to fit is a 19 tooth. Also, I think T. Deguzman mentioned he's running a 6.5t with a 21 tooth pinion. So you may want to consider having some pinions smaller than a 23 tooth on hand just in case.
Also, just as a note. The higher the "boost or timing" is set, the higher the temps will go.
Here's Tekin's customer service # 208-634-5559
The reps at Tekin provide the best customer service I've ever experienced with R/C. They're friendly, happy to help, and they know their product very well.
Hope you find this info helpful. Cheers

I take back what I posted before. You can't shim the center motor mounts because of the top decks! They have to be level. You would have to shim all the top decks and the center bulk head and the motor mount. This would also weaken the structural integrity of the top decks and may put unwanted flex into the chassis. It opens up a whole can of worms.

Just wanted to give everybody a heads up, I ran the car last night for the first time. Started with tessmanns OCRC setup, dropped the ride height a little but car felt great. As far the heat issue I put a muchmore 30x30 fan next to the motor and the car didn't go over 120 degrees. I think some of u that are having the issue have a gear mesh issue. My esc fan broke off mid day, and since I didn't have a spare I continued to run. Esc never got over 115 degrees.

Manufacturers: Feed your motor 8.4v, configured how I'd get when I open the box, measure the RPM, and slap a sticker on the outside with the KV rating

For those that preordered a spur gear from Tower may want to check your order. Mine is being processed but instead of being the spur gear, the item is now pointing to the gear shims. I called Tower and they said that I had to email them my receipt that showed that the original description was really for the spur gear.
So just a heads up for those that are ordering another spur gear. Or maybe I could be the only one.

Yeah, I figured that was the root cause. But someone from HPI needs to tell Tower that they had them switched. Maybe they will realize it when they see an unusually high number of orders for gear shims and very few spur gears. But as of yesterday, Tower did not believe me and thought that it was my error on ordering the wrong item.

Hi Torrance,
Have a couple questions. I am on Ty's Reedy setup.
I noticed that at full shock compression the inner rear camber link's ballcup compresses into the aluminum mount quite a lot. Is that normal/acceptable? His setup has 0 spacers there. I changed to 1mm and it doesn't hit the mount as much but still a little.
Second, I have my gear mesh set pretty much perfect but still hear a pretty good whine at speed. Is that just the sound the center diff makes with 100K in it, or do I need my mesh really loose?

Heat....i run just about all classes og 1/10 cars on and off road...TC 17.5 being my hottest car of them all....in 4wd buggy I have been running 6.5t in them all including in the heavy Schumacher sx3 that's heavy and runs 3 belts...and b44.2 ....im in nor cal and it gets hot ...so its simple
Take timing/boost/turbo back to 0 deg in ESC
Dial back timing on the motor end bell to 0
Punch some holes in body front and rear...I tried holes on the side of the body and it helps with motors that have vented cans..but not much
Put a heatsink on it..(possibly with a fan on it)
My favorite though is just to buy a fan...doesn't have to be particular powerful as long as it moves the hot air away from the motor...with a few vent holes it will escape and lower temps quite a bit.
Once motor has been overheated...it will overheat easier in the future...but a new rotor and a drop of bearing oil can usually fix it...if you bought a cheap motor think about what makes it cheap...poor bearings,loose tolerances, weak magnets...etc it all adds heat...so when you buy a top of the line kit....why cheap out on a motor...and if you bought a top of the line motor why cheap out cooling it....
BTW most of my fans are mounted with 3m outdoor super strength double sided tape...it stays put just fine....I prefer sunon maglev 5v fan and plug them into the receiver simple and easy...I have tried lots of other brands both cheap and expensive and the sunon's have latest the longest and tend to have higher static pressure... And their frames are strong

I saw one of these cars running last night at NorCal and it was looking really good. Might make this 2wd buggy guy dip his toes into the 4wd world.
