Got to run my car properly last night. Well all I can say is HOLY SMOKE!

This this is unreal, I just changed the shock towers to the Hara ones and used the stock holes. It was so darn quick people were freaking out at my track. It has very very good turnin (remember I run a oneway) and the back end stays way planted in the bends. This car feels better than my EVO now that I have sorted the few gremlins which affected my first run.

Hopefully I can do some timed laps soon and get some more feedback.

I have a few questions....

This is pretty much box stock R40, with a RB Rody X.12, RD Logic pipe, front oneway, running 5mm front and 5.5mm rear. No toe in front, 3 deg toe in rear. -2 deg camber front and rear.

Problem I have, on a high grip, high speed track is the first part of the turn in. The car pushes, making me slow more than the Mugen MTX3 going into a sharp turn. Once in the turn, the car will pull from the Mugen.

Am I missing something, is my setup look off for the R40?

Thanks all...

Joe

try a softer front spring, then a stiffer rear if needed.

Or a softer front compound on the front tires.

Or a firmer rear compound on the rear tires.

Huh...and all this without the help of team drivers(posting),head engineers(helping),company tuning guide,new fangled technology,etc,etc,etc.........



Makes me wonder what the car would be like if we had the same "advantage" as other new cars.. (should i also mention how easy this car is to set up?........Naaaaa!!!!)..


AMG.....Great job......

That's good to hear AMG, The R40 is really a good car. I'm glad a lot of people are starting to appreciate the capabilities of the car. Keep on racing!

Hi all, my friend's R40 keep stripping rear belt and 19t pulley. We checked the tension in rear bulkhead and check if there's binding in the area. This is like the 3rd time for him stripping the belt and pulley. What other posibilities can cause the belt and pulley to strip? Any help would greatly appreciate.

Amg i'm not using the lap counter at the moment.....
Might be time for hpi versus kyosho versus bmi.
bmi has an rs12 not modded.
Could make for an interesting read.
Maybe get andrew and include the serpent?
One car at the a time and do a magazine style review?

Hi, this is my first post, and unfortunately it had to be a trouble shooting one lol. I have a hpi r40 as my very first nitro rc car and put it together myself. I would say that i was 95% successful in putting it together but i'm having a few problems with the 2nd pinion gear slipping off. How can I tighten it enough so that this doesn't happen? I noticed that my second spur gear rotates clockwise to drive the wheels and that is the same way the pinion gear off the motor spins to loosen. Doesnt make sense to me that it should spin this way, but maybe i'm doing something wrong? any tips would be great! TIA

Lucky for you the pinoin turns the spur gear, therefore the load on the pinion actually tightens it. What will loosen the pinion is when the clutch bell suddenly stops and the pinoin keeps going.
just get it as tight as you can without damaging it.

Maybe you have not shifted into second yet. The act of shifting should surge the gear tighter on the clutch bell.

Freak, something is binding or he keeps catching a pebble in the belt.

thanks guys, i've managed to make it much tighter with your help. Another question, does the 2spd need load to change gears? I had the car running on a block today with the wheels off the ground and it didn't shift. I double checked the adjustment screws and even tightened them down again and readjusted to make sure I had the same amount of tension on both sides but it still didn't switch.

SMZ I was freaking out for a while when I first ran my R40 because if you adjust it as per the manual specs it is almost impossible to tell when the car shifts it is that smooth!

My old car used to go wahhhh-chick-WAHHHHHHHH. (like the sound effects ) My R40 just goes wahhhhhhhWAHHHHHHHH, you can almost not tell when it shifts.

The only way to truely check that it is shifting is as follows:

Screw the 2 speed adjuster screws right in. It cannot shift now. Run the car on the track or elsewhere and note where the motor hits top RPM when you nail it. Untighten the adjuster screw to factory position and run it on the same course noting where the RPM tops out. Should now be further down the track.

Thanks AMGracer. That's what i figured cause my car looks just as fast as all my other friends cars with 2spds on them. I'll have to check with your method.
