I only run it forwards
you can put the fuel tank in the rear where its visible and it gives the model a very slightly nose down CG. If you're a sport flyer you'll like that. It also gives the model a more balanced look with the long mufflers mounted.
you WILL have to trim the canopy slightly more however the templates included in the manual make that easy.
forget about electronics issues. If you're running the 2.4 systems you won't see anything.
it will work equally well regardless of which direction you turn it so its more about which you prefer in terms of fuel location and plug access
