Savage flux xl build

Did a complete strip down and changed any worn parts, its a durable truck so it was only some drive cups and broken pins that need to be replaced.

But now to the fun part also changed the chassie plates to Alza racing xl 4mm and upgraded the motor to an 1717, to finish it off i also mounted the high speed idle gear and an longer motor plate.

What i like about these chassie plates is that you have two mounting options for the battery boxes, so you can somewhat tweak the weight distribution.


The body is torn to pieces so really nothing to show.

Hi,
I am also thinking of getting the alza savage flux xl kit and mounting a 1717 motor. What is max pinion gear you can installed?

Had to flip the battery boxes to make more room(battery mounting bracket are slightly asymmetric) and because of the diameter i had to mount the esc at the bottom of the motor plate.. I think both of those mods are an advantage, not only to make more room for the motor but also makes the battery access easier, and becouse of the esc location there is no more wire rubbing against the body.
Compare to other chassies on the marked these modds are like nothing

Regarding pinion size im not 100% sure to be honest.. One thing i know that 18 gets in there easy and 25 does not.

I have some 21 and 22t pinions on order and i think\hope they will fitt (pretty sure they will), besides i also have the high speed idle gear and if needed i could mount an smaller spur and bigger tire.
But i think 21-21 will fit, maybe even some larger ones(ore not).

Hi,
You mean there is no more room to installed the ESC stand because of the motor diameter? That will be a problem for me as i am using an MGM controller.

well in that case you have to cut out an small amount of material in the corner of the esc mount, no biggi.

Freddy what you have done is pretty much what I have on the go. On my work bench is a Savage XL getting a conversion done on it. I am also using the Alza TVPs and the 1717 mount/clamp (what ever it is called). Actually I have pretty much Alzafied this thing with pretty much every part Alza makes for the Flux. The only thing I forgot to order is the servo plate which I will get soon anyway. Gotta say that Dejan does some fine work.

Since I am going to use the Mamba XL on it a custom ESC mount will be necessary anyway. Thinking of mounting it above the transmission, just under the roll bar. Not sure how that will play out as yet.

Q: When you said the 25T pinion don't fit, which size spur was that with? Stock 44T?

With 21/44 gearing, 6S batts and the 39T idler gear you will be knocking on the door of 70mph and thats without even factoring in any tire ballooning. That is seriously fast for a Savage.

With the high speed idle and 21t-22t pinion the ratio\speed will almost be the same as with an 2200kv(44t stock spur).. Think the speed will be sufficient if not you can always get some bigger wheels
With 6s its deff gonna be a monster power and speed wise.

Wow , seems like more ppl are going down the path of using alza xl chassis and 1717 motor.

Hi fredrik,
Any update from your build? have you make your first run ?. Still waiting for my alza chassis and 1717 to arrived.

its 99,999% finished, just waiting for the pinions and stiffer red spring.

22t did fit fine, gonna try it out tomorrow.

I have a change of plan. Will installed a 1520 in my savage flux xl with the high speed 39T idler and Goliath tire. Since I have an 8s capable MGM controller, may tried 8s in the future

Had my first run and noticed a few things.
First the wires got extremely hot, also the connectors got hot and the esc fan was constant on, is this motor so power hungry that normal (fake) deans dont cut it?
The motor got 60C (140f) on this little test run, the end bell was the hottest place, so i believe this has to do with the hot wires and esc.
The battery even with the hot wires where not unusual hot, like 30c (86f)
Running 6000mah nano tech 25c

On the stock 1515 the esc and wire temp where normal(wire ambient ore close to ambient).

Regarding gearing, running the High speed idle and 22t pinion with stock spur it was almost the same speed as with 1515 and stock gearing,, mayby slightly lower. gonna try some bigger wheels ore an tires like the terra pins ore somthing like that.. really need some suggestion regarding that.

(it was slightly hard to film and drive at the same time)

I think you are way over-geared. With the high speed idler, 1717 motor, 22/44 gearing and on 6S you are geared for over 70mph and that is before you factor in any tire ballooning. Way too much I think and the amp draw from the heavily loaded 1717 motor would be pushing the MMM to and probably beyond it's limits. If you don't believe me enter your setup into the Speed calculator on Scriptasylum.com and you will see. Drop your pinion to 18T and you should be geared for just under 60mph which I think will fix the overheating problem.

Also Deans (even worse fake Deans) connectors don't really cut it in my book when it comes to high draw applications. For a setup like yours the Castle 6.5mm bullets would be much better.

if you check the gearing with the motor kv you will notice it geared for an lower top speed now than with the smaller 1515 motor and stock gearing. also after the rebuild the drivetrain is smother and not least i was only driving on taramc with and bigger motor, lower gearing and smother drivetrain.. the weight increase compared to the stock xl kit is also marginal.
besides im not running 6s but 5s :)

i checked all the connectors and notice that one of the deans on the esc was badly soldered from factory, the wire was barly touching the bar. so i reoldered and took it for an test run and wolla a lot more power and no more hot wires.. but the fun only lasted a few min before esc smoked on me.. also noticed it wasn't any spark when i connected the batteries so i believe the esc was faulty from the previous run.
When i think about it i should have taken a pic of the solder job but i dident now the esc was about to smoke on me.

so the with the 1515 the solder job did an ok job,but with the 1717 i got hot wires. so the 1717 must pull a lot more current through the esc
