Hyper ST Brushless conversion!
 

I brought a Hyper ST Pro roller last week( Minus Centre Cvds and Spiderdiff) for $250AUD which i'm very happy with.

So today i go on to making my own motor mount(I don't want to spend money on the RCM mount if i can) and it took me a few hours to perfect it and i'm quite happy with the final result apart from it has a slight amount of flex, but does that matter?

I plan on running a 70mm 2300 medusa with a MMM on 4s when i get the funds.

Pics of todays progress:

Yes that motor has no shaft as i dropped it last night and it broke off which i'm not too happy about!

The mount still needs sanding and polishing but apart from that it's pretty much done.

NIce mount, and the motor shaft is definately an "oops" moment, what Esc and batteries do you plan on running?

Flex in motor mount matters - Ask Ben (b16)...

You will just chew up your spur and pinion / Worst case you will break your motor shaft...

Well today i made a new mount out of 50mm aluminium angle and im impressed with it. Best thing is it flexes 0%

Pic's to follow tomorrow.

All it needs now is a MMM Combo, 4s zippy and a Nice radio.

The mount seems somewhat far from the spur. Are you sure you won't have any problems with the pinion reaching the spur? Even though some pinion gears are pretty long, I prefer to not have the pinion overhang (extend further than) the end of the motor shaft.
Since you have machining capability, why not machine a mount that replaces the rear center diff bulkhead like RCM mounts?

Hmm, i don't think so. I put a pinion i had laying around which is very close to 1 mod where the motor shaft should be and it reaches easily.

I see that Tekno stock a range of "long" pinions which are double hardened. They seem like the way to go.

It just takes so long to measure, drill, tap, file, cut, sand and polish to make another mount. If this one doesn't work the next step is the RCM mount.

Well its been a while and i still haven't got everything i need.

Today i paid for a Spektrum DX2.0 with reciever and two servos for only $150 Aud and this thing is brand new so im pretty stoked about that.

Next thing to get will be a Motor and ESC Combo but i cant decide which combo i want, its a toss up between the MMM 2200kv combo and the Tekin RX8 Combo.

Could someone please tell me which one would be a better choice and why? Pros and cons.

Cheers

Hey
 

Hey Mystro ,good to see your making some progress with the truggy .....its looking good.I'd go with the MMM 2200kv set up .its a proven set-up and works very well .

cheers jas

I'd go with the 2200 combo as well. Looking good, but you'll get some gear mesh probs when the chassis flexes leading to a chewed pinion/spur and some metal shavings, which are super fun to clean up..

The Monster looks like its the way to go. I have heard from a mate that the MMM doesn't really like "cheap" batteries and the zippys wont really cut it....whats another good brand Lipo that wont put me out of pocket?

Bl RVO: I don't know what you mean about having chassis flex because the Hyper St pro's shassis is very stiff...?

your mate is full of it then. As long as you have some idea of the power needed to run the system a zippy battery will do fine. High MAH and high C rating.


Look into the 5000mah 25-30c turnigy packs.

What center diff did you use? (you mentioned it came w/o the spider diff)

what tooth was the center spur?

Thanks!

Im using the standard 52t diff.

Also, what diff oil would you use in the centre diff?
