MBX5T conversion

[nuz69]

Hi everyone,
I am happy to be able to post and reply to the thread of this wonderful forum yet ;)
As the title says, my project is to convert a mbx5T nitro into Brushless configuration. I have already an idea on the ESC : MMM v3.

==> For the motor, I am still hesitating betwen the 2 Castle motors : 1717 1580 kV and 1520 1600kV.
I know that Its better to put a powerful motor like the 1717 to minimize the heat and optimize efficiency, but i dont think I can find a motor mount capable of holding this very strong and heavy motor without colapsing :(
Therefore, my choice would be the 1520 1600kV, but I hope his power is enough to run without too much heat.
What is the best voltage for thoses motors, 5S or 6S Lipo ?

==> Is the RC monster motor mount strong enough to hold thoses big Castle motors ?

==> I am also searching the best battery tray for this chassis. The losi one would be OK or maybe you have other trays to advice ?

Thx in advance for your answers.
NuZ.
