Best Rally Chassis

[Honza]

@smirk-racing so far, my favorite design was TB-03 with custom chassis I made  5 yrs ago - mid motor and shorty lipo. I have only one picture from early stage of build. Little problem of this design is, that main drive shaft gets into way of steering. I had to redesign it 3 times, before I got satisfying geometry. But that's for competitive rally, where 45° steering lock is good start  

This design is reason why I think that TB05 or TA07 in front motor configuration would make capable rally chassis with only minor mods. 

Other designs (not mine) include TA02 with longitudinal battery and fromt servo, Xrays with various mods often with motor moved forward, some XB4 conversions, even some TRFs.. XVs are used too, usually with custom chassis which moves CG towards to rear axle.

I guess a second question to this is what is a must to upgrade and what sort of motor would you run e.g. sports tuned?

I think there is a point here between rallying for fun and rally as a race, very few people are lucky enough to have a local rc rally club involved in 1/10 rally.
 

It makes complete sense to me that from a racing perspective a stock XV01 would be less capable than a more rear weight bias vehicle. We build most touring cars that way because it makes them more stable and easier to drive and thus faster, only makes sense that on a “rc” rally race that this would also be the case.
 

If your racing you want to get around the course as fast as possible, the last thing you want to do is go sideways!!

Yet when 99% of us say we want a rc rally car for either bashing or scale driving then what we are really saying is that “we want to go sideways”. I  still maintain for that application there isn’t a better overall platform in 1/10 scale than the XV01.  
 

A. I want the best 1/10 scale rally all out sideways big grin machine = XV01

B. I want a scale rally race car specifically for competition and avoid going sideways cause it’s slow = converted rear/mid bias touring car.

Will have to google this one...

I think that good example of onroad converted to rally is Nicadraus FF03 - downstops need to be shaved to allow more droop. Then some filling of front arms, which allows C-hubs to drop deeper into arms - now I'm not sure if newer TRF419 style suspension has enough material, but older 416 arms didn't have problem with rigidity even after substantial amout of material was removed. With raised suspension, softer springs are needed too. Longer shocks are better, but not necessary.

Sport tuned or RS540SH are pretty capable.

 

@Falcon#5 no need to google

What, no love for the DF-03Ra?

I like df03 more than xv01

DF03ra discontinued? I cant seem to find them anywhere to check on prices

Actually, all designs I mentioned were based around moving weight forward. XV01 is only exception, because it already have too much weight in front in basic configuration. My TB03 goes sideways pretty well, when I allow it

The postage could be the killer though: from Germany to Australia will be about €40.

Yes, and the AUD is very weak at the moment which doesn’t help

I’ve got a DF03RA, I actually prefer TL01LA for rally work if I have to choose that Era, but I like my XV01 much better. 
 

I think if you loved the TA01/02 as a rally car then the DF03RA is a natural progression. The XV01 is altogether modern arrangement. All of them are heaps of fun really, but my XV always gives the biggest grin.

Totally agree with you on this.  The XV-01 is a blast to "pendulum" around tight turns swinging the rear of the car around as the front pulls through the rest of the turn.

It’s just the fact it goes wherever the front tires are pointing, you don’t have to wait while the whole car gets into position, it’s just so hard to explain why it’s a different experience to driving a TL01/DF03RA/TT02. I love my TT02S and my TL01LA, the XV is just more naturally adept at pulling off those gymkhana moves or touching the apex with the nose while being full opposite lock and being able to stay on the apex all the way around. It’s not even close to being the fastest way around the corner but it sure is the most fun.
