And your problem is? That is what happens when you put thick oil in the case. As long as both wheels rotate freely in the same direction you are OK.

Grab both wheels simultaneous and see if both rotate freely.

Yeah it is the THS pipe. This pipe is extremely similar to the RD Logics Turbo II pipe. Out of all the pipes I have tested this pipe makes the most power across the powerband that I have found. It does seem to run out of puff slightly on the top end.

I recently bought an HPI r-40. It runs great, but I would like to know what's the best configuration for the 2 speed tranny?
To have good speed on straigts and good torque for curves?

KLANDERMAN - That will depend on engine RPM and track size of course. I would try to find the optimum 2nd gear by selecting the gear that provides ~ 85 - 90% maximum RPM at the end of the straight section ( you want the engine to just get to the top of the power-band before the straigth section ends). After you determine this 2nd gear, then find the first gear that gives good good transition as is shifts from 1st to 2nd.

Basically, your engine has an optimal power band within a specific RPM range. You are trying to always keep the engine inside of these RPM limits at all time. Make sense?

Anyone running those RD logic engines? I hear they are so good, but my LHS doesn't seem to carry them and I can't order over the net. Whats another good engine? The RB V line up are nice, but for the price of a V12 3 port I can get the X12 5 port which is probably a tick faster. I currently run an MT12 and although it's stil hardly been run, I want something more. I think it's not that fast.

I would absolutely go for a RB V series over an X series....don't care about 3 port,5 port,whatever..I hated the x series....the V series is as smooth as an OS.......You got the Fastharry guarantee on that.....I'll tune that engine for free,and set your car up.......if you don't like it.........just bring it to Nanuet as soon as we start racing

I just got my RD Logics Dennis Richey engine. I just got through the breakin process and was able to race it once. Initial results look real good. Engine was keeping up and passing many of the guys who have the modified engines. Great for $190!!

I can 2nd that. The RD motor is basically a STS motor which I have been running for around 12 months now. For the money this things flat out haul ass. You cannot go wrong with them at all.

The RB V12 also is a brilliant motor, it is like an easier to tune torquier NS12. Does not quite have the top end yank of the NS12 but its drivability is 10/10.

Sounds good. Now its down to the V12 and RD engine. I'm thinking of setting the R40 up though with some lighter parts and so on since I'm so use to it box stock now (and it's seeming slower to me) before a new engine. I'll fire up the MT12 to see if it still will impress me before I change and sell it.

Default Please help with car's height!!!

Thanks JAG for the tip on the 2 speed trany configuration.

1.My next question is how high should my r40 be from the ground, front and back?

2. I'm using a team orion wasp engine, but I don't know if it's a reliable engine or not, has anyones used this engine before?

3. What'sa good first gear ratio, can anyone give me an example, so that I can blow the competition out of the water. Im using the stock configuration, but I'm very new at the hobby, please help.

Ride height - as low as possible to lower the CG. A good starting point might be 5mm - 6mm front and rear. Say good-bye to your shiney new chassis I designed some "skid plates" out ot HDPE and they work great and keep my new HPI lightweight chassis scratch-free !

Gears - You are using purples then if you are stock. If the track is highly technical with tons of sharp hairpin turns, try the GOLD first gear for better acceleration out of the corners.

Reducing weight or especially rotating mass for better acceleration. But this is secondary to mastering your driving skills!

Default Body and wind resistance?

Thanks again JAG for the tip on the first gear ratio.
We race at a parking lot, but the straight away has atleast 60 yards. the plastic gear for the first gear has 48 teeth, should I use the same gear with the gold clutchbell gear or what do you suggest?
Does the body affect the performance with the wind resistance of my R-40?
I use an HPI nissan 350z 200mm body to race, but I practice with an HPI opel vauxhall 190mm.

Does the lightweight 2 speed tranny work better in straights?
