Big Rock Do the 3s BLX need the fan when running on 2s?

[Adaptive]

My kids have recently taken to running their 3s BLX trucks (Big Rock and Typhon) in tje novice class at the local track. It's kind of a pain for them to open up the receiver box and plug in the loaner transponders and then restuff the wires etc. They are only running on 2s. Is the fan needed at this voltage? If not, it would be much easier to unplug the fan and then plug in the transponder to this (already accessible) port.

How long are the races?

You could also attach another extension cable to the rx's battery port and have the other end of the cable out of the receiver box to make it easier for your kiddos.

Or just get a Y-splitter and add it to the fan's port so you can tap off of it.

For racing on 2s I would just remove the entire heatsink from the motor just to cut down the weight a little bit and then use the pigtail from the motor fan to plug in the transponder.

Should be fine on 2S but also depends on ambient temps. Won't damage anything but might see thermal shutdown. Try it out.
Y-cable is definitely the way to go.
