I replaced the wire with carbon fibre strutes cynoed into brass tube then screwed to fin and stabilisers on all four surfaces, ie above and below the stabilisers. I've used carbon rod push rods with ball joint connectors. I've not needed up rated servos using Futaba 3001 or 3004. did strip one gear on a heavy landing. Replaced the u/cart for wire as all my flying is of grass and forget the spats.
