Gear: GWS Pico 4-ch rx, HS-55 feather servos. Same Hitec tx; didn't even need to program in a different setting! The "Swizzle stick" M72-6 wire-wound antenna fits entirely inside the foam. Some say this would reduce range, but visibility limits range earlier on a ship this small. Range would definitely be reduced if the prop snagged the trailing wire in a stall turn! (Certainly lighter than the Deans #1101 one-piece 6-inch whip antenna on the leading edge of Picojet 2.1's fin, later embedded in Speedwing.)

"Climbs like a homesick angel." Not adding any weight (i.e., major CF reinforcement or longer-lasting 12-cell NiMH packs) is the right approach for this overpowered surgical instrument. Far quieter than Picojet; at reasonable altitude it's drowned out by a single car a quarter mile away.

Motor mount reinforcement: That 80-gram metal can hanging way out in space cracks the thin foam under it after the first hard landing. Epoxy in a 5 mm CF tube below the ABS motor mount, from the aft extremity extending forward as far as the foam reaches. That's stronger than anything else on the plane, and I have proof...
