Savage brushless conversion ... another one
 

Hello to all the brushless specialists,

I just finished my Savage X ... :yipi:

This is my 1st post, but I visited this forum 1000x during the last 6 months gathering a huge amount of information, so thanks a lot to everyone !!

And here is the result: My Savage web page

Savage X SS
NEU 1515 2.5D
Quark 125B
MaxAmps 5s 8000mAh

Very nice

And welcome

very clean i like it alot

Officially the sweetest brushless Savage I have ever seen. So incredibly nice. Now all you need are the FLM extended a-arms. :smile:

When i was at Mikes place i drawed some parts for a centerdiff savage as well. It will be a bitt different than yours;

motor sits in front, next/above the steering servo/batteries in the rear.

Perhaps Mike will sell them as a kit.

A kit like that serum would sell very well. I definitely know I would change my next project if Mike sold a kit for a center diff Savage.

Wonderful conversion, looks very neat. What kind of speeds are you getting out of that motor?

Concerning speed, I just can refer to BrianGs R/C calculations where I got 46 mph with my 11 pinion+46 main gear, but 11 is really minimum and everything stays really cool (really cold). There is enough power to gear up to .. maybe 14 or 15... but who wants to speed should take a 1515 1y. My setup is fast enough for me, and short gear makes a lot of fun on gravel roads :-)

Like Serum said, motor in front would be a better... now with the batteries (more or less in the middle) it got a bit heavy in the front. But this was the only solution to keep it compact and tiny. Mike announced a kit for the Savage but he is really busy and needs some more time.

Yes, maybe some extended arms (for christmas :-)... but more urgent will be a plastics or delrin spur, the pinion is getting weak already (nevertheles too much power :-))

Yes, that is VERY clean! Almost looks like something straight from the factory (a little better actually). Good job!

...how did you get that carbon in there ? is it very fine sheet and its justscrewed between the TVP's and the parts? looks great...

yes indeed, 2 sheets of 0.3 mm, easy to cut, then a bit of glue on the TVPs, thats it. Then just make holes where necessary and screw it between the plates. I think it protects a bit better against all the dirt and stones flying around when you accelerate ...

Nice that you like it :-)

...Great pics Helms...thanks to you i am beginning to understand a whole bunch of stuff i didnt even know i didnt understand...

...Could you tell me, or direct me to a thread where i can understand why the front shaft is so LONG and then so SMALL in the rear?

well, there is no thread telling how long the drive shafts have to be... this is your decision ... you decide where you put your motor.

I did not like to have the batteries outside the TVPs, I wanted to have them inside the chassis, so I had to push the motor to the rear, the batteries to the front. As the motor is close to the rear differential, the drive shaft got short... and to the front it passes along the batteries, so it got long. I just measured the length I needed, and Mike fabricated the drive shafts (very well) (thanks again to Mike!!!)

...understood...and serum suggests power source in the rear...hmm...ok...

motor in front ... but there is the steering ... this gets complicated .. or you loose a lot of space, I think the batteries will not match any more inside the chassis. But try it out, we will be curious seeing your version.
