Hi guys...after my MRX4 brushless conversion... now i let my hand touch down to those babes running brushless... really in love with brushless system....

Well...got in my hand now :

Chassis: Ham 1/5 Race Chassiskit Latest Edition
Motor: Neu 2215 1.5Y
ESC: Hobbywing aircraft 12S 100A ESC
Power pack: A123 battery...


Have a look at these following photos for clear views

Now... Here is the list of wat I have to doto conver this Harm babe to brushless

Motor mount, motor shaft so that can mount the motor as well as to hook up with pinion gear

First I have made this motor shaft... it's just got one end too thin... the end that will be bolted with motor shaft... as it 's just too thin.. it wouldnt fit a screw..inside.....so i wasted my time... but gained myself lathe skill

Plz luk at the following pics... I havent finished this conversion yet...running out of time...will get it done ASAP... all i need now is an motor mount and battery box... willl keep u all posted....

That's great man... I wanna do a 1/5 now!!!

Good luck with those A123's and that Neu... I think LiPo's would be the key choice here...

30 genuine M1 cells will provide plenty of power for that 2215... and personally, I think I would use A123's for a large vehicle like that as well.

Nothing wrong with A123s for 1/5 scale- plenty of room on that chassis for a 2p setup.

Awesome looking rig there, especially the bizzare rear suspension- any pics from the rear to get a better look at it?

Nice lathe work too- that shaft should work out fine so long as the motor is mounted at a perfect right angle to the chassis- dont want to introduce any flex to the shaft, as the pinion will wobble like heck and snap the shaft/ destroy the bearing. You knew that already though... :lol:

I think that motor's KV is a bit much for that ESC if running on 12S... unless you gear the car down.. What gearing are you planning on using?.. Project looks great man! that shaft, coupler idea is awesome.. Similar to what I have for my Rampage.. Great Job...

That's aweswome! Someone buy all my stuff so I can build one!! :lol:

The quality on that thing just looks simply outstanding.

Are you planning on running a 10s3p pack? That's 30krpm, sounds pretty powerful though, maybe too much for 2wd? Can you get the 1/5's on-roads in 4wd?

He should be safe to run it, if he could gear it low enough.... Else, I'm just worried about the ESC...

thanks for all yr replies n ideas...

by the way... plz dont upset those A123 fans... i know they getting crowded now..... thinking of the advantages of A123 b4 blaming them......


I think im gonna run motor with 12s of A123 coz :

A123 got 3.3V/cell so ... 3.3V x 12 = 39.6V....

while the motor can get up to i think..42v ... would be safe enough...

and the power from 12s A123 will be roughly.... 40v x 70A = 2800 W... with those 24t pinion and 41t spur... well... ...the car will be spinning around....

And with the motor mount... i think the 6mm thick L bracket would be kul enough to handle the motor... 1 side of L brac... will be mounted directly to the chassis,..and the other side will be mounted together with the clutch holder and side chassis.... and finally with the other end of motor.... i think im gonna use 2...3.. of 6mm thick acrylic..to hold up the motor... that be kul.....

4wd conversion:... i think i can do that.... if i got complete rear ends....

1 of my bros..working in materials department for CSIRO Melbourne... he can supplies me free Magnesium plate..at.... any sizes..any thickness... with these ... i can modify and convert them to 4wd on rd.. but this will be later...

by the way... just let u guys know that... it was really lucky for me that.. the Neu motor for Aud $400 and car kit... just only Aud $500 ....,.. i bought them off ebay au... never though i would win the auctions... but i DID win....

With front hydro brakes fitted this thing will lay some serious rubber........WooHoo...

Looks nice so far. What are you going to do as far as motor supports?
