Savage XL-E

[Janezki]

Aaahh the snow has melted and the ground is somewhat dry - time for some spring bashing!

Now running with KB45-12L 1400kv, Mamba Monster Max & 6S lipo.

Everything went pretty well, until I broke the bigger gear from Kershaw's transmission. At some point earlier I overtightened the setscrew holding the gear, apparently damaging the threads. Now it got loose and broke the "collar" from the gear.

Here's some data from Eagle Tree:

Ordered couple of those gears from SDP-SI, but because I had extra day off from work, I just had to get the car running. Managed to fix the broken gear by drilling & tapping a new hole for the set screw, changed the motor to KD36-74-15XL 1100kv and was off to see if this thing could learn to fly...

Wanna see the video?


Click the picture above then.

I was pretty close to succeed in my teaching lesson, but unfortunately the front diff broke. Prolly the rear went too because the driveline was locked at the end... Transmission rolls well though.
Also one plastic spur met it's maker, because the motor shifted a bit.

Other than that I was really having fun.

...janezki thats some great stuff...Your driving surface looks quite loose...any over-heating problems on it? Good to see you using the truck for what it was designed for :D Great stuff

Thanks - the 1100kv motor didn't really get too hot, so no probs with that.

Got two new transmission gears from sdp-si with very reasonable price of $19.97 including postage to Finland...



... and started to disassemble the truck to see what kind of damage I've managed to make.
The rear diff seems to be ok, but the front had all four screws cut from the bevel gear, which then jammed the driveline. Bevel & pinion gear look ok to me, but the spider gears are damaged. Also the diff cup will have to be replaced, because of the screws that are cut inside the threads.
