Longer B4.1 Vega on the cheap!

[MHeadling]

Hi Guys, Just a quick one to show you how to do a +6mm wheelbase mod on the Vega B4.

I understand there is a new long chassis in the pipeline for the Vega B4 but this will be a good stop gap and costs next to nothing!

The pics do the talking really, but just attack the rear arms with a dremel and make sure the diff outdrives have clearence.

I measured back 6mm and made the cuts.





As you can see in the second shot I have spaced out the top of the shocks with some blue spacers to keep the shocks in line.

I am yet to run it but Mr Xtreme's car went well with this mod so sure I'll be on to a winner!

did you test this yet?

I just did the same mod, and will have a go on an indoor clay track this coming Sunday

The difference between that mod and a +6mm chassis, is I would assume the gearbox is also 6mm further back, affecting the weight distribution, by just extending the wheelbase, you have moved the CofG forward not rearward.

what dcm has said is right, all you have done in move cg forward wont work the same as lengthening the chassis,
you have also altered the angel of the drive shafts compared to the diff position which will also alter your forward drive

Well this mod worked well on Mr Xtreme's Vega B4 so looking forward to trying it out.

With the Vega B4 you flip the rear arms giving quite an extreme drive shaft angle, the car has plenty of drive so will be interesting to see if I can get it a bit smoother with a little more rotation.

If it doesnt work I'll just put it back to normal!
