electronic placement 450pro

[noddyflyer]

hi folks i need to install a flymentor in my 450 pro. ive removed the tail servo mount to give more rooom. the rx is 8 ch, too wide to fit inbetween the frames.hw 40a esc fits on the outside. f/m just fits inside but the servo wires are too short but not by much. could just strap it all to the outside but it will be prone to damage or falling off, just looking for ideas,anyone...mick
