I now have everything in place, using a Wren supersport, 2 X 5 cell nicad Rx packs & the ECU lipo in the nose. The Scorpion after all its mods weighs 18lbs 2 ozs & balances at 160mm with the gear down & a full UAT. No nose weight required. Standard size servos all round Except rudders (Hitec 225)

Regards

Jim
