21.5T brushless system?

Post  AndrewH on Mon Jun 06, 2011 3:38 am

Hi guys has anybody ever tried a 21.5T system in their clubstock car?
I hear one can buy a non adjustable esc and a motor combo for around R1000-R1200 that apparently has the same performance of a silver can, but obviously a lot longer racing life.
Just an idea........ What do you guys think about running a control rubber tyre (like the sabres do) and a brushless system like this.
It might result in awesome racing.

Like I said just an idea, what do you guys think???????

That is a brilliant idea and since there are only about 8 cars that run this class we might be able to put this to a vote. It was discussed before and I think everyone liked the idea and now that we do it in the Sabre class everyone can see that it might work. For one I think it will be way cheaper in the long run and by controlling the tyres and the rollout we can have an absolute blast!! The tyres that we use in the fwd class has to last you a whole national so it should last even longer on the 4wd cars. It means you might get away with only having one pinion in your arsenal. The cost saving in the long run will be substantial.

21.5T Brushless System?

Thanks for the info Andrew. As Raymond says, this was discussed at our AGM, and we wanted to feel the participants out. We will definately discuss it in detail during our off season, and put it to the vote for our 2nd season of 2011. - Sounds good!

my opinion is yes for sure. I think the correct way of doing it will be to guage the 21.5 to the average Johnson 540 and then give the brusless guys a fixed rollout they are alowed to use. I think the tyres should be for everyone. As I said, just my opinion.

Just a quick question would a fixed rollout have the same affect for all chassis?

Your opinion count alot,its just that there's now so many newer models running,FF1,the Sabre crowd and some of us still trying to get our clubstock old class running to levels where we never could reach,its like I said a long time ago,I stay one season behind,just as I think I'm getting somewhere a new class get introduced,and it cost alot of money.

thanks,and u obviously know I don't speak for only myself,even if 21,5 turn is long term the better call,money is the issue and the club's members per class.

We've just had a few days of very heated debate about this same topic, but, razzor made a very valuable point which you guys might want to consider.

He has personally used the 21.5t bl motor and ran out of pinions to gear it right, they need a 60 - 64mm rollout to be at peak performance, this then is waaaaay higher than you can gear a silver can, so it is going to run away from the silver cans cause its achieving 10 - 15mm extra per revolution, bear also in mind that the bl motors run at muuuuuuch higher rpms than a brushed motor. The older chaps will remember this happened in SS and 19t when bl was introduced a few years ago.

Razzor suggests using a 17.5t motor with a club spec esc or a esc with sportman mode, with no turbos or software upgrades switched on, the reasoning behind this is, you cannot gear the 17.5t motor so long, it uses roughly the same rollout as the silvercan does, hence they will both have a similar speed. This is in theory, so testing will need to be done on your track to see if it's actually a reality situation.

Use it, don't use it.

Here's a link to our heated debate.

This does make sense, will the cost be the same for the 17.5t as opposed to the 21.5?

I am willing to be the guinea pig and try the brushless system as well as a set of "control" tyres on my clubstock car, if the guys approve?

all info here will be appreciated. What I had in mind was to gear the 21.5 till its on par with the fast johnson motor and then limit the gearing to whatever we get to. Keep us in the loop please.
