One of the German manufacturers, WWS Racing produced a 4WD buggy called the Fox Pro 4WD with the engine rotated sideways and like the much later Ferox the engine leaned in..... The buggy was due for release in early 2005 but I don't think it made it beyond the prototype stage. There was...

Jim, welcome to the forum. I have asked one of the mods on the mcdrc forum to sort out your registration, if you don't get anywhere post here or send me a PM and I will chase them up. Please can you post a photo of your shocks and I'm sure we can come up with a solution that will prevent...

The inside of a MCD LSD found on RCU The output shafts do wear overtime and become 'floppy', I have not experienced this problem though. Even if the stock CEN/FS diffs are not sealed I would still recommend you try using something like the FG special grease or even a heavy weight...

I wouldn't bother with the MCD LSDs, I have used a front one in a couple of MCDs and although it does improve the handling and the traction out of slow speed turns they are too expensive for what is a conventional diff with a strong spring to limit the slip/rotation. I would recommend you try...

Its an early Race Runner Evo 1 (also known as a Pre Evo...) with the long travel front suspension kit upgrade. Clive

I bought one of the first batch of V4s that came into the UK and despite my best efforts I haven't broken anything yet....my V4 is basically stock, no alloy upgrades or limited-slip diffs. It has been bashed at both the local motocross track and largescale off road track and without question...

ONBs sent their own engines not those of their biggest USA rival (ESP) to Victory to produce a Pro pipe exclusively for them. I have been testing one since the beginning of the year in my Evo 3 The pipe has an amazing top end but to be honest a slightly disappointing low end. The new...

Nico, the blue spot compound tyres are excellent, they have a very low wear rate and once upto temperature provide amazing levels of grip/traction. I have a set of the asphalt tyres on my Rally car and they are still going strong after two years of racing and hard bashing... I believe the...

That is one nice looking car. I would thoroughly recommend you cut out all the side windows and most of the rear. It improves the air flow under the bodyshell and keeps the engine running cooler. When I first raced and bashed my Rally car I only had only side window removed just for...

Have you tried ordering the Samba Four Power Ultimate pipe from Mogatech (www.mogatech.de) in Germany? The Victory Rc Pro pipe produces more power/torque than the new Samba one but it is only suitable for tuned engines. I have been using both of the pipes on my MCDs and they are both...

If you are using the stock MCD tyres (170 or 175mm diameter), try 33, 30, 23, 26 but make sure the engine is not pulling high rpms. If it is change to 33, 30, 24, 25 or even 35, 28, 23, 26. There is gear chart in the 2009 MCD spares catalogue...

Chris, the track rods are the rod arms/turnbuckles, part number 131-4-DS-1. http://innovativehobby.com/mcdrodarmlongadjustmentturnbucklem6rlthread.aspx The long travel shocks are fine provided you use a heavier weight oil than you would use for bashing/racing a Race Runner off road. Also it...

Chris, I forgot to mention you need to use the shorter trackrods front and rear. I would recommend you try running the car with the long travel shocks before changing to the short or medium travel ones. Just use a heavier weight shock oil though. Clive

Chris, You need the shorter upper wishbones, the existing lower Race Runner Evo 2 wishbones can be used if you remove the black plastic spacer and use a shorter bolt for the red plastic rose joint to screw onto. The Rally car (and Pre Evo) also used shorter dogbones/driveshafts. There...

Chris, I ran my converted Pre Evo (Evo 1) with both the medium and long travel shocks at the front and providing you lower the ride height and use a heavier weight oil the handling is still good. The problem you have with the later Evo 2 and 3 is the on road wheels/tyres stick out beyond the...

Chris, I converted my Pre Evo (Evo 1) Race Runner to a Rally car early in 2007 for on road racing. Apart from the bodyshell (found on ebay for £15, about $25) I tie wrapped a large foam bumper to the existing steel bumper, installed MCD on road body mounts and so I could use the MCD on road...

Ticky, I can thoroughly recommend the new Samba Four Power Ultimate pipe. I have tested one in my Evo 3 and it takes the performance to another level compared to the original Samba Race Runner pipe. There is so much more low and mid range power/torque and the top end is good as well. It...

The pre 2008 internal diffs gears did occassionally fail/break. The diffs were redesigned early in 2008 and I have not heard of anyone suffering any issues with them. I have the pre 2008 diffs in my three MCDs and have never suffered any failures. Normally the failures occur due to poor...

The black plastic gears can be made to last along time providing they are run-in carefully when first installed. Take it easy for the first 5 to 10 minutes - no hard acceleration just gentle runs. Clive

James, I only used medium travel shocks at the front and the original short travel shocks at the rear. The suspension geometry was initially way out but it only needed the camber to be adjusted using the top turnbuckles. The ground clearance was acceptable but nowhere near that of say a...
