go to the viper thread and ask. I think a 16 tooth works.

I'm running a 18t pinion on my 6.5 murffdog on a small / med size track. I've also used a 19t when I wanted a bit more speed.

depends on what your running right now. count the teeth and just go down one tooth at a time till you find the right temp.. investing in a temp gun is one of your best bets!. avg motor temp is around 165 degrees. im running a tekin rs with a trinity d3 5700kv stock 81t spur and a 21t pinion.. after a 5 minute race im at 118 . after 6 minutes im at 125.. but. i dont need anymore speed on the track so im just staying with whats on there.

my orion 10.5 runs at....170 after a full 4650 pack =]

I run pretty well with the 7.5 guys 8.5 ETC. Im ganna stick with this. I qualed 2nd on tuesday in the a and 6 on friday( 2 full heats about) And i found it easier and easier to get use to. Also its not hurting my 2wheel drive like many say it does. I just know not to drive like a 4wd.:)

how is everyone venting their bodies? can i get some pics

b44.1 top deck mods
 

Just a question from a cross over carpet racer. Just started running a B44.1 to try to stay sharp for nitro season, and was just wondering if more chassis flex would be a tuning option? I have cut the top deck in spots on some older touring cars and it really seemed to help rear traction. I also know that all of the current 1/8th buggies are trying to acheive more flex. Anybody try this?

p.s. sorry if this question has been addressed, new to thread. Thanks

There are better ways. Run a black anti roll bar, lighter oil, tires. Heres what I did. 25 in the rear 35 in the front black anti roll bar the B hub adaptors. Now the best thing ever is tires. I run super soft rebars in the rear and m3 hole shots in the front all with aka red inserts. With no weights and the rear is planted. If I want more steering I use the silver roll bar or loosen the front diff. Just depends on how much steering more I want.

From the shock stand offs, chassis to the inner hinge pins you want the kit as stiff as possible. Flex in the chassis will effect the performance of your suspension. Even more so than tire selection its the most important component in the performance of the kit. I didn't want my previous post to sound like tires where the most important thing, but in that set up it made all the difference.

Thanks for the info, but I was just wondering if anyone has tried cutting the top decks? My car is dialed already for my track, just seeing if I could shave a tenth here or there. I think i'll try it, worst case, I'm out a couple bucks. Thanks

Thank you:)

Let us know how it works out.

Very nice wiring job on the 4wd. Both look great though too. Were have you ended up spring and oil wise for the 4wd buggy with the Losi BB springs? Going to run my car with the springs this weekend.

Green 32.5 front, white 30 rear medium size and medium bite indoor partial clay track. Really happy with them. But there was nothing wrong with the silver and green combo either.

Hey nice layout with the wires. I like the stock setup alot. Im getting the weight but its still really fast. Set the diffs so off power my front end pulls me around which is great.

Wanna run the losi springs bad on my 2wheel i loved em, it floats with them.
