Gymkhana video - XV-01 or something else?

Myself and a few friends are in the early stages of planning a gymkhana video and I'm pondering what chassis to use.

The terrain will be mostly urban and some off-road. It needs to be a "car" type chassis rather than a buggy as the bodyshell is important to the video. 

My first thought is an XV-01.  I'm not sure whether the long damper spec - or converting a chassis to long damper would be required. Does anyone have any experience with the long damper over stock? 

Also, is there an alternative to the XV-01 anyone can think of? Doesn't have to be Tamiya. The chassis needs to be rugged but can't be a baja or fast-ish crawler. Weight is an issue as the location is overseas and is somewhat off the beaten track.

Here's a 28 page thread of pretty much everything you would need to know about the XV-01.

Myself, I'm a huge XV-01 fan.  My favorite chassis of all time, and the most fun to drive. 

I have the long damper spec and it's adjustability is great.  You can lower the car enough to work on straight tarmac, or you can raise it up for more ground clearance for more rally/offroad terrain.

The XV-01 is very versatile. It’s probably the best all round chassis Tamiya has made.

The front motor position does provide a direct steering feel, and it is quite easy to pull off some very Ken Block style moves in tight spaces. It would be a good match for what you want.

There isn’t a great deal of use in the long damper spec unless you intend to cut and grind many parts of the chassis to get the extra travel. Once you’ve attained the extra travel then the hard sway bars out of the sway bar kit is a must or you’ll just be upside down all the time. 

The plastic cva dampers yield about 3mm of extra shaft travel which translates to about 5-6mm of extra travel but even then some cutting/grinding required to get there. If you change to gf01 damper set then potentially you can get as much as 15mm more travel but the droop stops have to be cut from the chassis, the arms and hubs must be grinded as well as most of the arm mount removed (meaning it’s weaker but also an alloy part wouldn’t help as you’d need to cut half of it off too.).

The biggest advantage is having that huge droop off jumps like a real rally car does but after that you’ve just got huge body roll and massive dive to deal with and sort out, it’s not for the uninitiated in suspension and sway bar setup.

However don’t let this put you off the Xv01 it’s probably the best candidate for gymkhana style driving especially if you need to be able to do low speed drifts on rubber tyres. The way it pivots on its front tyres has to be driven to understand why it’s so far removed from what a mid or rear engine chassis can do. And why it comes to videoing and trying to be realistic it’s probably the only car on the market short of a front motor drifter that will put the tail out and not skid the front end along with it in the way a real car would. 

If your film budget can stretch it, if reccomend a XV01 or XV01LD for your off road stuff but have a separate XV01 pro TC for your tarmac work. Luckily Tamiya just released a fresh batch of XV01 pro TC.

now some people complain and the complexity of the XV01 chassis with its spacers and shims however these spacers and shims relate to adjustments for castor, rear toe, anti dive and anti squat among a host of other adjustments Of which a TT02 has basically none of those options. But any half decent touring car does.

Thanks for all the advice guys. 

I have thought about taking two cars but can really only carry one car and a few parts. We're on foot all day so carrying two cars and all the gear will be a pain.  

Will get an XV01 :)

Just take a normal XV01 with a few differently setup sets of shocks. Quick pop on/pop off for the different driving. 

For very tight low speed stuff you might like to have a front one way, for anything super fast I wouldn’t bother though. For moderate stuff a loose front and tight rear, however the faster you go the looser the rear needs to be and tighter the front to settle down the handling. 

I’m guessing if your trying to film though you won’t be going very fast.

Gymkhana... TT02. Wide arm steering and locked rear diff

I have a TT01 with a locked rear diff - is there any way to alter the steering for more angle during skidz?

HPI makes a couple of Ken Blocks' cars, why not use one of those?

Yup. WR8 Flux gets my vote. It's mad on 3s

As a mid-engine zealot, I can attest the XV is an incredible rally/tarmac machine.  I bought it because its layout mirrors the 1:1 Lancia Integrale (front engine, AWD... heck even the motor is transverse).   I also switched from the TT02 as my basher/beater to the XV as it is possible to adjust suspension unlike the TT.  I also love the protected internals, if you have snapped a belt due to a rock... you know what I mean.
