Electrics install

[bald eagle]

I have a 501x worlds edition which I am trying to fit my electrics in. I have losi xcelorin speedo, micro spektrum rx, and a futaba s9550 servo. I cant seem to find anywhere for the speedo. It catches the steerring linkage if it goes in front of the motor, too big behind the motor, and if i place it behind the servo, I have no access to the lower motor screw. I have thought about a different size spur gear, but surely this is a bit of a sacrifice to install the electrics.... help?
