Pumpkin rear-end

[WILD ONE]

Can someone please let me know how to add a third shock to the rear of a Pumpkin (the R/C variety)[] I've seen a pic of one in someones showroom, but I can't remember who it is. They attached another shock between the gearbox and the chassis, to replace the silly little springs on either side that break/or aren't there. I just want to know what the best way to attach it is, and what shock to use. I've got a spare shock from my Ferrari F-40,(58098)the one that connects the chassis to the rear. Will that one do?[?]

Cheers'

Hi,

The mod your on about is in stewie's showroom.

He has done an explaination on how to do it and posted pics.

Looks like a top job and I may have to do it as well to my lunchbox so many thanks stewie! [^]

It's a well worthwhile mod to make, I've lost count of how many of those springs I've had to replace, and I've only had the Pumpkin a year. There's quite a bit of room there so I would think that more or less any shocker will fit, I'm going to use either a Mini-T one I have spare or possibly one of the friction dampers from one of my other kits.

Here is "another option" for you guys that may want to make the pumpkin or lunchbox handle better. Toss out the 2 small springs,and the locater bar for the rear end. Drill a small hole in D7 and D8. Install either a screw or a screw pin(the screws with threads just below the head)to secure the rear end. This provides a nice solid hook up point for the entire rear end housing,plus still provides plenty of movement up and down.[8D]

Mervyn, this only gets up-down movement on both wheels at the same time, it is not possible to just have 1 wheel go up/down....it works but wil not make handling much better..... the 3rd shock solution does....

I don't even think you need to have a thrid shock, my bet is that a solid rod would also do - just to secure the axle in the middle. This will give a similar construction as the Fighter Buggy rear axle, which is also fixed (yet pivotable) in/around the middle. [8D]

Sjoerd,I would agree.I have raced these for many years and have had/built probably 30+. I think the secret to making these handle is 1) use a damper thats at least 1/2inch shorter than stock,and 2)"fixing" the rear end at the pickup points where it hooks up to the chassis.[8D]
