AAA Battery box 88000 disassembly

[kyphur]

Yeah, I realise that the 9V has less capacity but keeping the weight down is critical for my little train:

I also want to take advantage of the space reduction to try to get all the PF bits into a future small scale diesel loco.

This sounds like a perfect example of a good use for the pp3 > 9v adapter...

I just bought a RC buggy motor and a 88000 battery box and i built a rc car

The problem is that i have to open the battery box to take of the overload protection.

I dont know how to take out those 4 screws.

Does somebody knows a trick or a way to get those screws out?
