yeah i agree.

but how come i heard alot of people say they will only buy the evo4 is its 3 piece?

trf racer

1 piece.
it will be lighter and will produce less slop when it wears.

ok...so with the HPI pro4evolution III surikarn/hara edition
available now, and basicly addressing all the issues of the evo3s should we now jumpover to hippy racing?

Yes.

3 piece prop i think as with a 1 piece prop there is no room for chassis flex which will happen causing the gear mesh to alter/bind up hence there is still a chance of stripping gears. The origional TC3 graphite shaft was light in weight and combine that with alloy inputs into the gearbox's and thats as light as a one piece alloy shaft. Rick

Hello All,
I was just wanting to know from those guys with the Tech 3 piece Shaft, Do you have the shaft adjusted so that the shaft has no float in it or do you adjust it so that the shaft is tight between the ends. Also where did you put the second "O" Ring?? Not the one that goes around the alloy spur gear holder but the other one.

Any help is appreciated

what i've done is place the small "O" ring inside the front drive cup. and as for adjusting the float. i left about 1-2mm so the shaft can have some space to move around if impact does occur.

Steevo

Thanks racer,
Do you find it quite noisy?? Mine seems to make a lot of noise...

racer

your welcome Steevo,

yeah, i came across that too. you can try glueing the bearings to the motormount and gear cases. that way it will hopefully reduce the noise from vibration.

its up to you if you want to do something like that.

Everyone happy with the way there evos are running then? TTT. Rick

Mine continues to run well. I've done a few more things to make it faster like cleaning the grease out of the bearings etc. I'm looking forward to seeing if it helps. My ring gear fix is still holding strong. It sure is nice to not have to worry about it all the time!! I still find myself pulling the front tranny cover off to check and see if the gears are really not broken!!! No joke. I have also realized that the rest of the car is quite strong. I haven't broken one single part except for the gears and a slightly bent driveshaft.

amen to that Jason... i have run the o4/414/evo suspension for about 2 years every weekend, and have maybe broken 1 front arm, and bent 1 hingepin. i usually wear out suspension pieces before they break. what an idea!

The only time I break is when I neglect to make sure all my screws are tight. The car is as strong as can be. I don't worry about the one way gear for now since I am running a front diff.

For the tight track I run on the Diff works better for me.

I actually use the 1-way all the time. I have shimmed it. Usually when a tooth breaks it folds over into the the gear tooth channel. I have resurrected some gears by taking out the broken pieces and reusing them. If you bench test it it usually does not skip.

It does make funny noises but if it saves some money in gears and does not fail who cares. My latest gear after breaking probably has over 100 minutes on it after some banging and bashing.

right now,i'm using the rear diff gear as a oneway by doing a little modification.Dremel the middle hole to a bigger size to fit the oneway housing after that i use the peguin back plate,solve no more stripping...
