I ran another week on mid motor, I put my D3.5 back in since they aren't banned and it runs cooler than my sonic 17.5. We couldn't keep the track as wet this week due to time, but the car was still good, still cannot be driven as hard as RM, but it easier to "catch" when it does break loose. I changed to 30/0 from 25/2 and couldn't really tell much difference. I'm going to switch back to RM now, I want to run outdoors at a few tracks in the area and don't want to chance it with the MM setup.

I am lol..... Does not mean its not the best car I have ever driven. I know it makes no sense. My wife called me a moron. AE has been pretty good to me. Although my B4 does not handle as well, It drives good enough. I am last place with anything i drive, lol. So why not be last place with my trusty ole b4... I am an AE fanboy, but unlike some people I will admit when another car is better. And the RB6 is head and shoulders above the B4 in everything aside from parts availability and looks. The B4 is good "enough" for me. I drove my 22 this weekend, that thing is a POS. its build well and seems like a good idea, but it just does not work. The b4 is consistent and drives ok, the Rb6 is consistent and drives very good. I want to get my kid driving the b4 also, so I can sell the 22.

Hey guys, the Losi Aluminum Front Inner Pin Brace (LOSA4137) is the same width thus fits. However it is quite thin and I'm afraid it will fall off if not held in place. The plastic bumper will not push against it and hold it in. Any ideas? Thanks,

I just picked up a couple kyosho 1/10 cars. Any advice on running this car? Springs, swaybars, etc...
Also what pinion/ gearing are you guys running for 17.5 blinky class

I forgot to check, what spur gear are you guys running for 17.5? The smallest KY spur I saw was 76.

Also I can run AE spurs if I swap to AE slipper plates/pads, correct?

69 is what you want, but we've found out that the K plates are too big for the kimbrough style spurs, the plates ride on the plastic, not the pads. I went the avid route and put a vts on my car with their topshaft, some others have dremeled the b4 plates to use. You can get a 72 kyo spur, which will get you close, but still not a low as most (32/69).
