Here you go:



I had the original 52t spur on place when doing this.
First I measured the hole pattern of the Tekno mount (which is 32mm center to center btw.) and attached the motor with 15t pinion to it.
Then I placed the mount over the plate so that the pinion touched the spur and marked (scratched) the outlines of the mount to plate. I noticed that I could probably use only two screws for mounting because the plate has openings at the center and a little "notch" at the front (marked with yellow circle at pic) which might make the drilling a bit difficult, plus the center rear driveshaft was in the way (I was lazy and didn't remove the plate from the car...)
Then I made marks for the two 4mm holes to be drilled to 32mm distance of each other. I drilled second holes towards the center of the car, just next to previous ones and used dremel to grind the gap open - now I can move the mount to mesh the gears with different pinions.

Two screws with thread locker seem to hold the mount on it's place well enough.


I got the tranny fixed with the spare gears, loosened the slipper a bit and went for a little drive yesterday.
Managed to drive a full pair of packs with no problems. With second pair I was jumping from a small snow bank, had a bad landing and heard a loud cracking sound and...



...broke both upper & lower suspension arms.

Heard the cold can weaken plastics so maybe why its so fragile? I have beat mine to death as nitro and never broke a arm.
The lipos your using whats the specs? Being told I should look at nothing less then a 25c rated pack.

[Janezki]

Yes, it was probably due to cold weather.
I have two sets of lipos - both were originally 6S1P packs, but I had to divide them into two 3S1P packs because of the battery holders.
First pack was originally ZIPPY 5000mAh 6S1P 15C and the second was originally ZIPPY 4000mAh 6S1P 20C.

Just ordered one Kershaw direct drive gearbox for my XL. Now let's see if that holds up my throttle finger.

[Janezki]

Got my hands on 2spd gearbox idler and drive gear and I must say that they are "a bit" stronger looking compared to the 3spd ones...


(2 speed gears at top, 3 speed at bottom)

I might convert the internals to 2spd just for the heck of it, if I break them again before Kershaw's transmission is here.
Also, I ordered a set of black RPM a-arms since I'm not really a fan of excessive aluminium parts.

[Savage03]

I have so many tranny gears laying around I probaly have those to, had my savage since they were released some years ago and just upgraded as I went along. Think the ticket will be the flux tranny parts or the Kershaw tranny your getting, very interested to see how that works for you.
I will update my thread here shortly with good news

[Janezki]

You will need more than just those two gears - the idler shaft atleast and probably even more, see the exploded views.
If I have the time (and interest) I'll try to see what exactly is needed or can it be done with minor modifications to existing parts.
