Hyper ST Pro Brushless clarification....

Correct Arct1k - you were the guy I was thinking of running both setups! Cheers for that.

This is my first conversion as well - so trying to be mindful about what I do.

So - seems like there are positive benefits for going both ways with the batteries. Obvious simplicity for the single battery, but added benefits in going for x2 lipos. Hmmmm.....need to think about this more I think.

As for diffs - 100K in middle diff and it still unloads? Damn.

I have read posts all over the web about different configs relating to diff oils (specific to Hyper ST mind you). To be honest - seems like opinion is all over the place! I have seen positive reviews (front/middle/rear) for 5K/20K/3K, 5k/10K/3K, 10K/50K/3K, 10K/100k/10K etc etc. Some people putting 140K+ into the centres. All over the place!
Did my head in actually. Settled for 10K/60K/4K for my Hyper Pro. Also bought a bottle 20K in case 60K was overkill.... Maybe I should have gone higher tho? Time will tell.

As for motor protection with the middle diff flip - I read somewhere that Mugen MB chassis guards fit nice onto the Hyper ST, so I ordered a set. They widen the body and provide impact protection as well as higher edges to prevent debris from getting into chassis.

Trying to cover all the angles I can with this car....bound to miss something though....

It all depends on just how much power you are putting through the system. On 3S and 4S the front diff really doesn't unload all that much. Its crazy the power jump from 4S to 6S. Thats really crazy. I can control the power now without much of the software aids in the ESC. But I couldn't track it on 6S. Its just too much power. Though I make take it to the local track and set the TQ limiting to .6 or .7 and see if I can control it there. Would be funny to blast down the straights like mad. Except the end of the straight is a brick wall.

Truthfully I've been having alot of fun with my Mini 8ight. So much so that I'm considering buying a Mini E-Revo VXL so I have that too at the indoor track.

Yeah - well - no indoor tracks near me unfortunately. Outdoors bashing only so strength is really important to me. Bigger is better outdoors...

Soooo...

Decided to make life hard for myself and go with the saddled lipo config. I figure I can always reverse it back to 1 x lipo it if I am not happy. If I do it the easy way with single battery from the start and I get the truggy operational - I will never be motivated to mod it again. So yeah - will do necessary tricky chassis mods now for diff flip I reckon.

I started stripping the car down, flipped the diff and visually it appears like the front chassis brace is definitely going to get in the way of the Castle 2200kv I have on order!?!

I know other guys with this config have used the 2200kv castle combo, but yeah - while I cannot confirm for sure as engine is not here yet - I am pretty certain it will get in the way.

Scanned through the forums and there is some mention of the space limitations at front, but no real mention about having to mod chassis braces with a 2200kv motor?

QUESTION - can someone who has flipped the centre confirm for me what else needs doing in the front? Arct1k if you read this would appreciate your input as I know you have done this! Already thinking maybe I should have followed your original advice mate...

2200kv castle is approx 75mm long and 41mm wide - from my rough measurements - engine will hit that front brace. Am I going nuts?

Comments I read about flipping the diff on the hyper mentioned grinding chassis for centre diff gear clearance, but have read no mention of anything else?

Looked at all the pic's I can - hard to tell what other peeps may have done.

Grind the brace for clearance?
Shim the engine so it is angled way from the brace?
Alter the diff mount slighty? Not real keen and changing drive train alignment tho...

How the heck to you guys do it?

Appreciate any input on this.

Cheers.

That would not be good for sure. I was showing off one day in a campsite with my mbx5t on 5s and lost focus for a sec and wham...bathroom wall jumped out at me. Not to much damage considering the speed of impact

Thanks Arct1k - thought as much.

Again - appreciate the input.

Cheers!
