it fits, but the mounts are about 1/2 inch longer on each side, so i just got a dremmel and trimmed them..... i like this gear better than smartech's.... its stronger



ill take a pic in a few minutes

thanks but i found the problem for one screw on the clutch bell was loose but the motor was still locked up so i took it apart and the rod end that hooks to the crank was all messed up there was metal shavings every where this sucks cause i bought this car so i wouldnt have to put a motor in my nitro rush
so what kind of motors do you guys put in the smartech speedy tigers

The most popular power plants are the HPI T-15 Nitro Star, or the O.S. .18 CV-RX. I prefer the O.S. It's a beast!

layitlow, did you break it in? because maybe thats why you threw the rod. your suppose to run about 10 tanks through it at low rpms before you go fast

ooh yeah! if it came from excel hobby you have a 6 month warranty on the motor and the transmitter. hopefully this helps

ouch! my car started revving uncontrollably, and doing fast circles. i grabbed it, and stuck my hand under the body to pinch the fuel line. i accidentally stuck my thumb into the fly wheel. it tore a huge gash in it, and the nail. pain[&o]

i got from excel hobby how do you do the warranty will they replace the motor or the whole car and do i have pay for something
THANKS i forgot about the warranty

I just drive my buggy in my backyard and the street is the os.18cv-rx that much faster than the HPI T-15 for the money on ebay the os.18 is alot higher than then the hpi T-15. My brother has a hpi firestorm with T-15 and so far its a prety good little motor

You should have a warranty card. i think they just replace the motor

well dang guys...i didnt get to drive my buggy on the ice....its still broke.....and ive been out of power and cable for the past week this sucks....and im too broke till income tax to get parts...and its supposed to snow 8 inches here tonight and i still cant drive it.....and yeah you can use the warranty card....only if you have "proof of purchase" i bought mine from excell and i got no reciept sooo....i couldnt use my warranty card and when i emailed the guy about a reciept he never answered me back....

I tore my car all apart today for cleaning, lubrication, and to make sure every thing is tight. all my parts are intact. i lubed up my differentials, and the gears are in good condition. so far i haven't broken anything, the car is made pretty well
codykrr, whats wrong with your buggy?

well...i am missing both driveshafts. the front shock tower is bent up...(it hit a telephone pole) and thats about it.... nothing about $30.00 cant fix but im broke....my house flooded and i had to get a new carpet cleaner and fans running burt my electric bill up...soo i have to wait untill income tax......[:@]

second day with my buggy broke the bearing carrier thing that hex conext to fixed it with some JB weld then broke right front axle and then threw rod in my motor cant wait to get income tax to get a new motor but im going to try to call excel hobby and see if they will help my out.

But you guys said i have to have proof that i bought it or something i got it on ebay but i dont think they gave me a reciept could i just sent them the shipping label that came on the box they shipped to me or does it have to be a reciept from excel hobby

see thats what i wondered too....i was going to use the shipping lable....but my wife had thrown it away...so i there went that idea it may work...im not sure...and does anyone know...or have there heard of this ..... www.sicorpusa.com i emailed him and he was pretty cheap...just wondered if anyone had problems getting parts from him.

sorry, the link is http://www.smartechracing.com/web_20...10143/part.php ...on the left it says U.S.A. distributor sicorpusa... the guys name is danny wong or something ....anyone done buisness with him?

ok, how often do i have to lube my differentials. and with what. and also what else might need lubing once in a while? do you lube the tranny at all?

i lubed my diff with white lithium grease that sayd safe for plastics, and metals

if your wheels have bushings lube them after every run

ok but how do i lube my diffs?

If you want to lube your diffs you need to take it off the chassis and either take it apart or try to fill in the hole under it. I think the diff case is pretty sealed and packed with grease from factory so i dont think its necessary to lube them. i Have huge problems with the driving gear in the diff case.. I get like 1 or 2 running hours before they`re totally worn down.. think theyre made of cast aluminium.. has no strength at all..

Docphysics: you got a nitro evader right? do you think it`s possible to transplant a complete evader rear diff onto a winner sport? I really need to find something more reliable as im sick and tired of replacing the driving gear.

wienersport, why do you keep wearing out driving gears? did you put a bigger motor in it? maybe you can pay a machinist to cut you some gears. i am taking a machinist class, but i haven't learned how to cut gears yet.

Wiener - The evader diff won't work. It uses a slipper clutch and spur gear to directly drive the diff, where as in the smartechs the rear diff is driven by the transmission out drive. So I really don't see how you could make it work.

ok is this true.....my lhs told me no other driveshafts will work in the speedy tiger other than smartech. i mean theres got to be one.....right?....someone told me carson parts....ive never heard of them....but are there any parts that will fit this from a more popular brand...so i dont got to wait....

ok. thanx! guess i will have to try to find some parts that may fit inside the gear box. yeah the bigger engine isnt kind to the diff gears. at high speeds when hitting small bumps it almost wheelies. its a blast as long as it lasts
