Actually, as I used to work as an electronics technician, I know enough about the current ESC's to design and build one from scratch (though probably not as cheaply as I can buy off the shelf, so I will simply buy one).

As I am building a new car with all new parts, it will be a current ESC, most likely a Speed Passion GT to match the Speed Passion motor, powering a Sakura Zero.

What is so hard about giving advice along with qualifications? e.g. If you are using a current ESC, try an FDR around ... or if you are using an older ESC ...
If I accepted your advice, I'd never even make a start!

Now is that the GT2.0 with or without Supercharger?m

Here's how it works : you need to be as specific as you can with your questions, in order to get a decent result.
You don't visit a doctor ,saying your leg is sore and nothing else. You can't get shirty when you get an incorrect diagnosis.

Now, there is a massive difference between the 21.5 motor characteristics alone.
Never mind the esc variables ....

What size track / layout / surface / grip ?

Your roll-out can be as low as 40mm or as high as 60 + !!

The SP I had, was up around 61mm with an SPX . Indoors,high grip ,maximum timing on both units.
This was still slower than the same setup, with a Novak motor , geared at 45mm.

1:1 knowledge doesn't always translate into rc that well.

As has been said until you have an ESC and a designated version of the firmware giving you any advise on rollout could destroy your equipment.

As Fleety said, look at the vast difference in rollout figures for 21.5. If you use the wrong one your ESC and motor are fried

Look at the responses from others on here. They are basically saying the samne thing. Get your ESC and version of firmware then ask the question

I'll be old and grey before I get a sensible answer from you guys... oh..., too late! It seems I will have to resort to the old tried and true methods of trial and error. Thanks for nothing.

While you're teaching grandma to suck eggs, it also works this way - if you don't know the answer, it's probably better not to answer at all.

If you are running a STANDARD (Factory) Speed Passion GT 2.0 and a 10.5 and are on a medium sized track, then a good place to start will be around 6.0 on the FDR, Supercharged about 8.0 FDR and 110 software about 7.2 FDR you will need a temperature gun so as not to allow your motor to get above about 160 Fahrenheit.
13.5 about 5.0, 17.5 about 4.5, 21.5 about 4.0

Sorry you feel we haven't helped you out but if we give you an idea and you blow a speedo or motor you will be upset at us.

Finally, someone who is game to at least give some advice! I appreciate it, thank you.

If I blow an ESC or a motor, at least it isn't life or death. I'll write that down in my notes as the wrong choice, buy a new unit, change my settings and move on. It really isn't that hard.

I started RC racing before most of you lot were probably born (in 1984, in fact), but I have been away from the hobby for quite some time and things have changed somewhat (now there is an understatement!). This is the reason that I am starting back in 21.5 and asking for a little advice. I will go about it the same way I always do, start with an initial setup, measure what I can, keep notes, make small adjustments and record what works and what doesn't. Hopefully I will progress, become competitive and eventually move into the quicker classes.

this thread is about the sakura car.

if you have a question regarding gearing, and in particular speed passion, then go ask your queries in the speed passion thread. If you getting back into the sport, than go to the rookies zone thread, or radio and electronics thread.

the first reply to you was short and to the point, as no one wants to read about brushless motor gearing and esc in a thread devoted to just this one car.
