Still. If you're going to go 2s, go with a 17.5.

Ok I think this has been suggested once before but you think that having a GT1 and GT2 class might be the best course of action? Have a GT1 class with 1S/13.5 for the newer guys and a GT2 2S/17.5 for the more experienced guys or for guys who have shown success in GT1 or would you prefer the other way around? I just want to see something get settled on for this class before we debate it out of existence

emm GT1 is the fastest class in FIA GT series.

unnless 1S/13.5 is faster than GT2 2S/17.5

Not sure, that would be a good opportunity for an open test. Maybe even have GT be the 2S/21.5 that wingman says that we're gonna end up with.

Aren't we forgetting that the pan car is designed to work on weight transfer, and the 2S pack is not giving that. Indoors it might just work OK because you have lots of grip, but the out doors guys are gonna hate you for making them run 2S!!

We have one person over here who wants 2S, and one person in the US. On the other hand we have ROAR, BRCA and eventually EFRA who want 1S. We have National Championships for US and UK proposing 1S, and we have battery and speedo manufacturers making parts for 1S. It won't settle down to 2S, it will be 1S.

Just my thoughts...

Here you go again. The class has been established with the 3.7 single cell lipo. It's going to be run that way at the upcoming national.The same way it's going to be run here at the state series in florida.Single cell is also what is run in the 1/12th cars. Now there is supposed be a split pack 3.7 cell single cell by someone but I've not seen it yet.Oh yes the single cell is also being used in paved oval for most of there classes also.

Guys, the top end class like GT1 should always have the fastest rule setup, kinda.

simply because if people think its slow due to things like the 1s lipos. it will eventually be created local series were they drive 2s. thats no good for the development a series/type of car.

besides it not ideal to have low turn motors going on low voltage vs high turn and high voltage.

if we say both setups produce similar output. They will have these characteristics.

low turn motors and low voltage

- Lower efficiency leads to more amp usage
- More amp usage leads to more heat
- More heat leads to more rebuilds.
- More motor rebuilds = cash.

high turn and high voltage.

- higher efficiency means less amp usage
- Less amp usage means less heat
- Less heat means longer lasting motors.
- Long lasting motors means more fun less cash in the trash.

just my 2 cents.

Mats,

The argument would be true if the electronics and motor gave a constant high current draw at low voltage. They do not tax the battery at all. There is more than enough current available. The motors tend to never over heat at 3.7 volts, much less get hot unless its geared wrong.

oki if you say so.

But it doesn't say its better.
Just that my heat argument is less important.

How fast would they go on a outdoors track with 3,7V and a 13,5T

60Mph on the straights?

if your from norway ( as your name implies) then your calculation from km/h to m/h is a little bit off it seems.

We go with a 10.5t 2s lipo on 360 feet straight including a large sweeper wich you can take full throttle roughly 53-55 mph. (85-88 km/h).

1s with 13.5t would maybe go 20-25 m/h or so? i gues.

ps:
or you meant it sarcasticly

Im just throwing the idea out there. I just want to see something decided on so Im not constantly having to buy something new every 6 months or so, but also there to be an entry level option. Have a slower spec for people to get into WGT and get their feet wet, but then have a faster option (kinda like Stock and Mod in touring car were originally supposed to be) for the more seasoned and experienced racers, kinda like the WGT and Expert WGT classes they are having in Vegas.

The 13.5 1S is much slower. I don't think I could get mine going that fast unless I went 2S and at minimum a 10.5. The intention is a skill class, not an all out speed class. The pro 10 class is still out there, but they use real low wind motors, 2S lipos and are 235mm wide.

A couple of points, I think there is more than one person wanting to run 2s in the UK and US . The CRC GenX10 was designed with 2s lipo in mind,even the BMI can run 2s stick pack.

Whats the problem with running a stock class 1s /4 cell and a modified class 2s/6 cell then the problem is solved surely? everybody is happy.

My opinion, allowing 2s enables possibility for touring car drivers to easily and at a lower cost make a jump to running GT10, less fuss without running voltage boosters so running electronics as they were designed.

I have run both 2s lipo with 13.5 motor and 1s lipo with 10.5 motor, eventually went to 4t motor with 1s to get some speed (using high gearing and esc timing) it just seems to be a lot of pushing things to the limit the 1s way. I can understand that some people want to slow the cars down but I want to race at a decent pace so a stock/mod class set up seems a reasonable solution.

I was exaggerating quite a bit. but still my parking lot "racer" goes faster than 40km/t. so in my opinion race cars should be a bit more of a step up in terms of speed.

I watched a indoor race at youtube from las vegas and 1s 13,5T was not fast enough in my opinion. At least not as a GT1 class. GT2 1s 13,5T would do. It was ok for that indoor track but on a outdoor its not good enough.

GT1 should go faster than that. and then 2s is the better option.

and due to that a GT2 series should also have 2s so its easier to go up a class, all you have to do is chance the motor to a higher turn.
