XRAY - Model racing cars

Hi ,
do you know the inner dimensions for the battery chamber in the 808, what is the max bat size I can use?
does anybody tried this one
FTX2561 - FTX VOLTZ 7.4V 2050MAH STRAIGHT LIPO RECEIVER PACK

thank you

I personally run an LRP 2300mAh LiPo Hump in the RX compartment, then put the Losi regulator and a Futaba RX in the long compartment. Fits very well.

If the Futaba RX is 2.4GHz FASST then I would try to keep it as far away from the motor as possible! It will shut off if the temp gets ~60Celsius. Because the radio box is next to the motor it is very easo to reach high temps

Radio box dimensions should be about (I think measured by Rocco ):
Battery compartment - 20mm x 87mm x 32mm
Receiver compartment (usable) - 65mm x 40m x 24mm
