View Full Version : Proracing Evo IV RB

Does anyone know if they ever made any or whether it was more of a personal project?

06-05-2007, 05:26 PM
I 'think' it was a stop gap project until the 501X was available - so the guys are running the 501X now instead. Not sure if they are still doing anything with this shaft project, cool if they are, but the guys are Tamiya bods and the 501X is hard to beat!

Bluddy Hell That was quick :D
I was just going to ask a few questions to whoever had one but it seems no-one to ask, thanks anyway jimmy.

Hopefully gonna use the concept to try and do the same to my TB Evolution III, without having to hack the chassis away.

IMHO I wouldn't bother, it wasn't a great car......

Why'd you say that mate?

07-05-2007, 11:43 AM
It didn't seem to go that well. Looked nice though.

mossy ishy and kirky are still developing the car so they have the choice between belt and shaft which i think could be a good idea

07-05-2007, 04:22 PM
fantastic, does any1 know if will be put in2 production? and maybe wen? :)

Where and when? I've only seen them run the 501 recently.

Does anyone know an email for Richard Isherwood or anyone developing the car, thanks.

The car is still getting developed as we speak. I ran it a couple of times on Sunday at batley and was posting times as quick as my 501. Should be able to see the car running around the track in the regionals.

08-05-2007, 11:24 AM
Cool, didn't realise you were still on with this - any new developments? Will you be running it along side the 501X until it's working well enough that you can drop the 501x?

08-05-2007, 11:55 AM
cool mike so it was going well glad to hear that did ishy run his

New developments are new suspension parts and some added steering which was the biggest problem. The car has some advantages over the 501X with it being shaft drive, but the two cars are completely different to drive.
I only ran mine on sunday shaun to see how the new parts held up.

28-05-2007, 03:55 AM
Any pics of the car? :)

01-06-2007, 10:26 AM
yeah Jim, any spy shots?

01-06-2007, 10:56 AM
Take off your zorro mask and use your eyes. There's some on the photos section at the bottom :rolleyes:

03-06-2007, 09:08 PM
:) Not sure why it's based on the Evo IV & not the V, has it been in development that long? Will it make it to production and if so when, I've steered clear of the 501X as I prefer shaft drive.
Ran a Predator XRS, now on a Cyclone D4 whilst waiting for the Aero A One but it would be nice to have a Tamiya off roader to go with our TB Evo 5 touring cars.:)

03-06-2007, 10:55 PM
They started on it a while back I believe (jimmys photos suggest may 2006) and also, the evo V seems a bit fragile in the drivetrain area. Dunno if they'll go into production, you'll have to ask them yourself

04-06-2007, 08:06 AM
mike west run his at durham regional and it looked really good out there on the track

04-06-2007, 12:01 PM

First of all congratulation to mike and proracing for their beautiful job;

I started a month ago to convert my evo5 in a off road car...
The cars will have all the evo5 transmission and bulkead and i hope to fit the 501X suspension

If you want i will keep you inform...


04-06-2007, 12:08 PM
Sounds good, Im im the process of attempting to do the same with me Evo III, there'll be a series lol

Thanks for the kind words shane. Really enjoyed running the car today as it wasn't planned (blown speedo in the 501X in practice). Had a few minor niggles with the car today with a rear shock coming off. The car is is going to stay on the evo IV platform as we didn't think the V drivetrain was upto the job. Not sure what will happen with the car yet as we only planned on building because we had a few spare evo's lying around. I'm sure if someone would like a conversion kit we could do one but it isn't cheap to the numbers made.

29-06-2007, 01:02 PM
chaps, dug this up for a reason.... in a deal I had for a touring car from the states, a TB Evo3 was included in the deal, as a chassis only, so was wondering what wishbones, hubs and driveshafts people are using, and maybe blag some shock towers!!

29-06-2007, 02:22 PM
DCM, ive been looking at getting my evo iii converted but havent been able to start for money reasons but I have some pretty sound ideas on how itd work out. PM me if you want

29-06-2007, 03:50 PM
I think Mike has most recently been using a 501X front end suspension wise and a Lazer ZX-5 rear end. Bear in mind that when they first started the project the 501 was unreleased, so a lot of the car was developed around Lazer/Tamiya hybrid suspension and custom carbon parts.

The car is a lot more than a shaft drive tourer conversion, wheelbase is longer for one, if you were trying to replicate what they have done all you would keep from an Evo III is the gearboxes and a few bits of hardware.

29-06-2007, 04:06 PM
I appreciate that, as for one, you have to make room for the slipper unit (which one is it?) and I would be looking at using 501X wishbones if need be, I think I got CVD's here to cope.

It's the ZX5 slipper but the Proracing buggies are based on the EVO4 not EVO3 which has a solid one section prop between the gearboxes The EVO4 has a 3 section one.


29-06-2007, 04:20 PM
can the prop be changed??

29-06-2007, 04:23 PM
No the gearboxes between the cars are totally different. The EVO3 only uses a single bearing to support the pinion gear in the gearbox as the shaft is solid. The EVO4 has 2 on each inputshaft. If you go the the Tamiya website you can download mannuals to see the difference


29-06-2007, 04:29 PM
I am looking now, it is the front gearbox that is the problem, as the Evo4 uses one bearing on the rear and two on the front.... hmmmm

29-06-2007, 05:25 PM
I believe Mike used a custom chassis to lengthen the wheelbase and hence the evo would be able to incorporate the Evo IV 3 piece shaft. This could then use the Kyosho ZX5 slipper shaft. The pictures of the Evo IV RB I hasve show it with ZX5 front and rear arms
