is 10th off-road the 'fastest' electric class?

[sparrow.2]

If the German PRO10 rules are anything to go by, definitely 10th pan cars. They run 5300mAh 2S lipos and no motor limit, so it's 2.5 and 3 turn brushless motors they are using.

They have to be carefull not to dump the lipo before race time is up and are currently lapping around the same speed as 1/8th scale onroad cars on open tracks.

I think if you geared the hell out of it and ran it in a straight line anything else would have a bloody hard time catching up...

Depends on soooo many factors, surface type (drag races generally on flat tarmac sure but is it dusty, wet, dry, cracked etc?) Would 10th offroad be running control tyres or open choice? i.e spikes or 'slicks', how long is the course, which way is the wind blowing?

Also can't 10th off road run touring/rally body shells? I can't remember for sure but I think I read something about that in the rule book, don't think I have mine to hand. That would help even the aero side of things out.

But one thing is for sure, I think 10th off road is the only class where we can actually go overboard on the power, for everything else it's as much as possible really. I also seem to recall 2 speed gearboxes being allowed in a couple of classes, about 95% sure it's allowed in nitro on road classes, I *think* 8th off road can use them but not 100% on that... more than one speed transmission would be a major advantage.

Here's a thought
Shot in the dark !
Maybee just maybeee !

The fastest electric car in a drag race would beeeeeeeee !!!!!!!




A DRAG CAR !

Lipo brushless big back tyres ! Built for it ??????

[millzy]

i say 12th

i think a 4wd 1/10th would come close but the 12th would win every time

[MK999]

no drag racing class on the BRCA tho afaik?

[Chris Doughty]

OK, so we eleminate the specialist classess,

IFMAR classes only

[millzy]

STILL 12TH

[ben]

Why dont we test it out? Im sure someone would lend you a 3.5 chris

[millzy]

sure lrp could sent him one

[Chris Doughty]

you would proper have to belt some Proline tires though, they would get seriously massive!

Toss-up between 1/12 and buggy.

Only one way to find out for sure.....

and as there are not currently any rules - they are exempt.

Pro 10 still has a set of rules, it's just that they aren't included in the current BRCA handbook. Current rules are 6 cell, no motor limit, minimum weight limit is 1400g. We were running 10 turn motors in them 15 years ago.

Well, i'm told that from a recent test, some touring car guys were hitting 58mph in full race trim...............

[Jonny_H]

I think it would have to be a covered-wheel class.

Our big, open, spiky tyres (and exposed suspension) would add a lot of aero drag - although if the rules would allow you to fit snoring car wheels and tyres...

[lochness42]

What about 1:8 electric conversions? I know that only Roar has some rules now, but maybe them or 1:12.

[LEGEND]

Well if you were to put a 2.5 brushless in a 1/12th scale and geared it as high as physically possible. Then in a straight line it would be almost un-matched.

[DAVIDZX5]

I was at a BRCA event last year, the people like andy moore, olly jefferies where hitting 63mph as the cub had a speed gun there.

I don't know that much about touring cars but would full race trim really be that different to a 'within the rules' drag trim?

The only thing that would change surely would be gearing if it was a long enough course, it's not like they would drop motor winds or do anything for more power, they're already doing it !

[niggs98]

straight line drag with any motor and current cell rules would have to be a buggy. 2.5 proline/losi tyres and massive gearing, yes we would get killed off the line but in overall top speed i think we would do it, most of the other guys are already on a 3.5 or lower to be competetive as it is, think the buggys would romp through towards the end. if it was an out and out no rules drag race in ideal conditions with any cells then either a 12th or 10th pan car would anialate anything in its path, years ago we had a pro10 with 12 cells on the motorway clocked at about 80 and that only had a 13 double in it

So when are you gonna hold the drag race test Chris?
