How to tune stepped mono for racing?

[Jesse J]

Also, can someone direct me to the specs on these three classes, mini mono, mono 1 and mono 2?
Like, hull length, motor / battery limitations, race course length, duration.
Any other specs would be great.
Even though we don't have these races here... I may try to get something going at the club level.

Thanks Erik! So the three mono classes are divided by total battery weight and max cell count And that's about it.
Are setups pretty secret, or do racers share their secrets?

Wait... Mono 1 can really only have 280g of batteries? Or is that per cell?
That is a 3s 1400 mah pack! How can it go for 6 minutes?
Help me if I'm reading this wrong.

3s naviga legal 5000 mah < 280 grams. http://eshop.mmodely.cz/tenshock-lip.../?currency=eur

Awesome, thanks!!

It is for the full pack including any wires connectors and velcro etc, everything attached. There is a fairly big weight difference in High C cells and the low C cells we use, a high C 2s 5000 would normally be around 300g, and you can get 3s of the same capacity under 280g. 3s 1500-1700 Low C would be <110g for the mini classes. you don't get something for nothing though, and the cells are rather fragile.

What motor do you guys use for mono1 on 3s?

[NativePaul]

Leopard 2860 3400 is probably the most popular, Lehner 1530/8 is probably the best that is popular. However I do know someone that switched from the Lehner to an equivalent 11 series Neu (probably a 1112/2d but I am not 100%) and loves it so that might be the better option for you guys over there if you want high end.

I hear Neu have moved their production to China recently though so maybe they are not as good as they were, I know hackers efficiency dropped through the floor when they switched from Germany to China, have you noticed the same from Neu at all?

Unfortunately, we have some reports of quality degradation over the last year or two.
Thanks weas, I'll see about that size.

Jackpot! Thanks buddy!

[Jesse J]

where would one find such hulls for purchase from the US?

[NativePaul]

I doubt you can find one in the US, we don't even have them for sale in the UK and we race them, we buy direct from the manufacturer in mainland Europe or Asia. I think you have a H&M dealer in the states (Is it rocket city racing? Not sure, for obvious reasons I didn't pay it much attention) and they could order you a Skyper mono1 or a Speedman mono2, but I doubt they would have them in stock.

Hey Erik, would you have similar for mono 2?
Namely, what motor and cell count, 3s2p, or 6s1p?
