Default HB Cyclone Gearing

Hi
I recently bought myself the cyclone HE and I'm having some problems with the gearing.
The kit comes with a 100T spur and I wish to install in the NOVAK GTB/4.5.
My first problem was that I had to replace the spur to 108T in order for the pinion to reach the spur.
Now my feeling is that I'm still not in the right gearing for it.
Can somebody please advise a spur/pinion for this car to work with the GTB/4.5?
Thanks in advance

you will need a 108 spur and 26 or 27 pinion.i run the RW gears.

LoL!!! i did exactly the same thing today. Got myself a 108 and a 26 and a 27pin.

BUt teh 26 looks like the mesh isn't that great? Any thoughts? 108/26 would be PERFECT... but i'm not sure that it meshes well enough. Feedback anyone??

Any larger on the spur and it looks like it might poke out the bottom of the chassis.

108t is the biggest you can go on it, its just that with the 4.5 it looks like the car has too much torque.

you can also grind of a little out of the motor mount , I can fit a 25 / 108 combo with a perfect mesh for a 10.53 FDR

Firstly - Big thanks to Marcos for helping me sort out the required size.
ANd for suggesting that you can indeed fit the 110 in.

The only reason why i didn't, is that i tried the 108 and it JUST just in without poking out the bottom of the chassis. I might get the dremel out and have a go at the motor mount because it really shoudl slide back a little farther.

So the cyclone isn't designed for the low low gearing for a 4.5 eh??
Better hope a 3.5 doens't pop out anytime soon..

it is but is like .010" and its really rare that you will bottom out your car completly flat and that the spur will touch. I ran mine an entire weekend a total of about 11 runs without any problems. I ran the HPI 110 spur and it still looks brand new. Jason (BMI) was there that day and saw it . Yor can get it to work just dont be a chicken $#@*.

LoL... new motor mount sounds good!!!...

I think i might indeed go with the rat tail file today. Our tracks here a plenty bumpy. I don't think a larger spur will survive. I do have my doubts...
Are the motor mounts on the Hara and suri editions the same??

LoL....

Hey man, the bent steering turnbuckle suggests otherwise!!! LMAO!

Yeah... i think i may do... the 108/27 will be fine for the huge 1:5 scale nitro track.. but i will need to go lower for everywhere else so i don't have much choice really...

I"ll let you know how i get on..
