Beginner in a wiry problem with a TK 7.0 problem

[modeler]

Hi everyone , first time builder and poster , i have acquired a TK 7.0 main boarded and radio station for my FT 17 project , Now the problem starts with a motors on the old gearbox and the fact that they burned out in a trial run (these motors and the gear box were all from a model that was sold in the 80s) . Now what i have found online is that Tamiya dual motor gearbox fits amazingly in the small ft 17 hull , but is it compatible with the TK 7.0 ? The connectors for the motors are huge and I'm worried if i tin on new smaller ones i might disrupt something related to the power supply . Long story short is Hang Long TK 7.0 compatible with Tamiya twin-motor gearbox? And if so how do i make it work ? thank you to all and I'm sorry if i broke any norm or rule about posting I'm very new .Thanks for the help and have an amazing day !
