Thank you Castle Creations for the 45 min. Final
 

I have debut my XB808 with Castle MMM/2650KV, in racing today.

3 qualifys of 5 minutes

Semi-Final of 20 minutes

Final of 45 minutes

Running amoung the nitro on 4S lipo.

Fantastic

How did you do? What gearing did you run?

14 T pinion on the motor.

Rest of the gearing of the car as the factory make it.

60mm fan over the motor connected directly to the 14,8v batteries. It only takes 180mah so nothing to wary about. I believe after 10 minutes the motor was on a balance between the heat it produces and the heat it dissipates with the fan. This balance was around 55ºC. After the 45 minutes the temperature was the same.

This mean I have reached a point where I can be all day long running my car without warries about the temp. Just like the nitro guys.

Fantastic. And this with the 2650kv motor. If it was today I would have buy the 2200kv to use with the same 14,8v packs. With the 2650 I need to have everything at the minimum with the ESC, timing and punch. Can not have it any slower now.

And yes, with "chinese" lipo.

How many battery swaps did you have to do in the 45 minute race, and what capacity packs? Did you do 20 minutes without swapping packs?

The 20 minutes I made with a 6000mah pack without swap packs. For that the race director made me do 2 stop and go, at the minute 7 and the minute 14, at the box to simulate the nitro pits.

The 45 min Final I made with 2 swaps. At minute 15 and minute 30. Packs of 5000mah.

Did you win?

I am not so good. I was 5th. And I should say I never thought I could be in the first 10.

My last Off-Road race was 20 years ago, running nitro of course. And it my first race with the 1/8 Off-Road electric car.

Last four years i was driving electric 1/10 touring cars.

Excellent PDM! Hope you work your way to the top man.

how did u fit a 6500 pack under the body?

I am using a JConcepts [JC0071] body for 808.

Raised the front pin 12mm.

The battery is 6000mah. Two 3000mah in paralell

My brother (Jopor) made the videos of the 45 min final. There are still 5 min missing, i believe.

That is a nice track. I will have to visit Portugal one day.

You are welcome.

This is Algarve, the south of Portugal.

Sim, e um lugar muito bonito. Cuando a minha filha estiver um pouco mais velha e independente, eu vo seguir todas as corridas de enduro (Sports cars) e umas dela e em Algarve.

How long did it take you to do the battery pit? Fueling a Nitro takes only a few seconds, even when I hurry with mine, it takes way too long to be competitive.
