having a replacement set of pins is less critical now that a set screw in the quick release is standard. (with the serpent vector if you spit off a wheel at speed you would likely lose the pin) but it is still a reasonable spare to have around.
I did get the grey speedline tires to fit but a pain i had to enlarge pin slots grind down face of rims where it locks on and grind off lower outer mount. the pins where cut down glad to here mugen kyosho work with just ctting pins. thanks.

Gary, are the RB tires you tried made for Serpent or for Motonica/Kyosho offset?
The axle pins on the P8 series are about 2mm longer than the slot found on most wheelsl. The pins on the P81 are notl.

oops, sorry for the confusion Gary. what Garen said.

the 'SPT' wheels are for Serpent Vector style axles and have the wrong offset and different axle length than the 'motonica/mugen/kyosho' wheels.

so with no mods the wheels will fit(jaco) is this right. i will pick up the new cars Friday and start the build this weekend, is the clutch new? and is there any problems with it so far? last year i ran the K clutch all season and would like to run the stock on if it works OK.

Now problems since than.

Greetz Stefan.
So you put extra heat shrink around the battery and glue that to the plate?

And that is perfectly fine by me!!

Mugen cars are not only great performing cars, but very user friendly as well. THAT is the key to selling a car successfully. If you can spend more time on the track and less time in the pits, you will sell a good number of cars. Motonica is using this philosophy from what I see in the instructions and the setup. I am confident that Motonica will do very well here. I am excited about getting my car in so I can build it and race it. I know a couple people at my track are excited to see the car in action!

Looks like and is like are 2 different things. The P8.0R 08 was used as the platform to test out different suspention geometries, and I think this information was transferred to the P81. The suspension geometry on the P81 is nothing like that of the Mugen car, and neither is the internal gear ratio.

I think gary47 was making a compliment. I find the Motonica P81 very refreshing and enjoy its simplicity. Definitely different from what I remember with my Serpent VETEQ and SMP Slide cars.

I like a car I can easily dial and spend more time on the track versus sitting in the pits, putting it on the setup stand and adjusting everything in micrometers so as to not mess up the balance of the car's suspension and rolling geometries.

Arno, ANY PICS OF THE FINISHED PRODUCT??? By the way, how did the engine mounting procedure go?
