This is not a kit question, but since I'm doing so many mods I thought it would be okay to ask in the Kit Forum.

Just bought a Tiger 60 ARF and a Saito FA-100. I have several mods I want to do, but wanted to run them by others who are familiar with this plane before proceeding.

List of mods:
1) Taildragger conversion - considering carbon fiber gear with fiberglass wheel pants - not using stock mains in the wings.
2) Enlarging rudder and maybe elevator. Some say it's not necessary, other that it helps on more advanced flying.
3) Inverted engine installation with pitts style muffler.
4) Larger fuel tank with possibly moving to CG and relocating radio gear and battery to original fuel compartment. This might help with the CG issues. ( I know when I put together my Eagle 2 ARF, I tested servo and battery placement before locating the servo tray. Glad I did, since I moved servo tray as far forward as possible and put battery nd radio just behind fuel tank. All this and still have to add a weighted spinner to just balance. The Tiger ARF has the servo tray already mounted)
5) Fabricate either a balsa or fiberglass cowl to make it pretty, just cut it off at the firewall and start there new. Not sure about cooling issues, but thought if I have air intake in the front and left the bottom of the cowl pretty open it should do fine.

Any comments, pros or cons, tips or tricks?

Thanks!
