Hyper 7 diff conversion
 

The diff ratio to tires is around 3:1 -3:5:1(estimate) on the hyper 7. Isd there any diff conversions to change the ratio so it is more like higher something like 2:5:1 ?Such as diff conversions,or putting trugy diffs or soemthing in the hyper 7?
It is for a custom project.

yes, 10t hellfire or 11t hyper st bevel gear should do it. also hyper st 52t spur would help.

It is a custom project,fitting a gas engine 26cc in it.I need to change the ratio in it since im not using a spur gear .
By the way it works it has been done beofre so please nobody say 'that engine is to big'. I have made the chassis longer.
By bevel gears where abouts is that gear?
Also i need to change the front or rear diff gears not the centre of spur gear or clutch bell, since i dont have one.

Pics please??

RE: Hyper 7 diff conversion
 

Here some pics,i have mounted the fuel tank that pic is about 1 week old. at the moment when i turn the diff input shaft it comes out to the tires at a ratio of about 3:3:1. I need a ratio of aroind 3:1 or even around 2:7:1.
The bevel gears is the one that connects to the diff cup in the diff right?

lol:)never seen that done before:)

Hahaha, that's crazy.
:D

Lol so eveone have an answer for the tooth ratio question?
I think the gaear that is on the dog bone cup that is in the middle of the diff,well the gear on that is like 14t.The big gear on the diff is something44 teeth i think(correct me if im wromn).You divide 46 by 14 and you get about 1.3 which explains the ratio.I think if i giot a 16 tooth gears for the cone that connects to the diff and will make a ratio of around 2.8.
So i need a tooth of around 16 tooth i think?
This is jut an esti9mate it would be nice if someone came along and told me the real teeth of the gears...
Anyway sorry for the long reply though i think i will neeed a higher amount of teeth not lower like j blaze said?

Bum[...so is it possible to change the ratio?

Why are you putting this engine in ? Nitro engines are much faster .
