Savage XL-E

[Janezki]

Ah, ok. It should hold up just fine.

When I saw Savage Flux I was thinking that there might be problems with the combo deliveries for the "ordinary customer". Seems like my thoughts were correct... :(
I bet that HPI has quite an amount on them in order together with Traxxas.

Janezki, do you have a pic of how you mounted the motor mount to the engine plate of your savage?

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.

[wayneb]

I'm going to try running the 2 speed tranny in my brushless savy conversion. but I'm only going to run it on 4 or 5s lipo. and see what happens. I just need to buy one shaft and the bearings for the tranny then I will put it back together and finish building the truck. if things don't work out I might switch the truck back to a nitro engine, but I don't know yet.

[Takedown]

Ya I blew my 3spd aswell in my savage awhile back.

Heres a few pics...

[Joram]

I have ordered titanium and Delrin gears. I think that is a very good solution for all problems:)

Look at my topic for details!

[Janezki]

Proper stickers now...

[Janezki]

Had to do something to keep myself busy, so I fixed my Savage with some lights.
Fronts are huge 20mm diameter blue leds which are attached to the bumper where the HPI "lights" were. I also glued fluorescent o-rings around them.
Rear lights are 12mm diameter red leds (not super bright), which are sitting at the bumber holes.
Leds are powered from receiver battery through channel 3 at my receiver so now I remember to turn the power off after driving.

When all the leds and wires are attached to the chassis, I don't have any hassle with wires when removing the body.

On to the pics -

(they're really not that bright, just long exposure trick)

rears:



Leds & o-rings came from www.dealextreme.com and resistors from local electronics hobby store.

[Savage03]

very kool Can you show a pic maybe of how their wired with resistors?

[Janezki]

I can't provide actual photo since I've got all shrink wrapped, but here's drawings how they are connected:

Nice trio of brushless power !! Looks like the Savage was out of commission though?

Yup - no fun for me until next weekend (hopefully).
