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

Chris Doughty · #1 14-08-2008

as the title says, could it be that 10th off-road is the fastest electric class?

think of all electric classes, if speed or runtime was not an issue, all you had to do was stick to the class rules which class would be the fastest?

frogger · #2 14-08-2008

From what I have seen 12th scale on road is faster!

Chris Doughty · #3 14-08-2008

sorry, my mistake, I meant potentially the fastest class...

legally, I could drop a 3.0T brushless motor with 6 VTEC4600 cells - we do have less efficient transmission maybe, but what else would get close to that?

Lee · #4 14-08-2008

When you say fastest Chris how do you mean?

Surely a 1/10th scale on road car is quicker if you mean in a straight line or on a flat track, but i do feel that there is more skill required to drive an off road car

EDIT: you posted whilst i was

Chris Doughty · #5 14-08-2008

I mean if everyone was to turn up at a drag race track and go for top speed, which class would end up quickest - each class would have to stick to their own rules.

Lee · #6 14-08-2008

Well being a sad ba****d i know that a touring car bodyshell does nothing above 12mph but cause drag because it starts to deform. so i think they will get to a point and hit a brick wall. so i think if we all turned up and geared the cars to the moon etc and went for it the 12th scale and tourers would leave us standing off the line but once our bigger wheels and tyres came into play we might have a chance especially with the advantage of balloonage

Id say 12th scale would win the drag race.

They weigh about as much as my farts...slap a 2 or 3 brushless motor in (Dont Nosram do a 2.5 nowadays?) and itll zoom off like a rat on crack.

10th offroad would have too much drag with the mahoosive wings. 10th TC still sticks to high weight limits even with LiPo.

12th gets my vote.

Touring cars and 1/12th are quicker, but only on flat surfaces and where grip is always there. I rekon you could make a 1/10th buggy go much quicker, especially when it works well on all surfaces. Look on the web and youll see videos of buggies and 1/10th scale trucks hitting over 60mph with brushless motors. But then again look at Cliff Letts touring car when he hit over 120mph, aerodynamics did play a major role in that.

He did also have his car powered by the National Grid lol

If you were to do this drag race on flat tarmac then the 12th would kill all.

Ive never heard of a 'drag' race going over a mixed surface.

12th scale - limited for 4 cells
TC - limited to 5 cells

would our extra cells overcome the drivetrain?

we would obviously cut the 'racing' gurney flap off the back.

Lee · #11 14-08-2008

I really think we could have a chance, the only issue we have is, could we make up the distance lost at the beginning of the race, we have an extra cell and i dont think the drive train is much of an issue its the extra 400 grams we have to lug around

10th scale Pan Car. It's making a comeback. With LiPo 2S power!

DCM · #13 14-08-2008

was going to say, 10th scale pan car chassis like an RC10L, as long as you can get the power down, it will out rip anything in a straight line, plus the shells are far more efficient at passing the air over.

but will that class have a motor limit in the rules?

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

I'm not trying to find out what chassis would be best for an insane speed run.

the question I guess I am actually asking is what electric classes rules allow you to make your car the fastest?

just out of interest really...

and no, I don't have a 3.0T to run at stotfold...

Tom3012 · #15 14-08-2008

i honestly think 1/12th pan car would win... but i reckon a pred, being low to the ground and very good aerodynamically could put up a good fight?

what is the weight limit for a 12th scale?
what are the weight limits for off-road? 2 and 4WD

1474grams for 2WD, 1588grams for 4WD
12th scale is 800 grams

Im with wraggy on this one.

I think weight would only play a big part off the line, I think the biggest speed limiting factor would be aero drag at the high speeds.

we have 1/3rd more 'power' (waits for clarkson) than they do, yet their aero package is much better than ours...

tough one to call....
