Graupner Terry. Speed 400 foamie powered glider (folding prop).
Maiden flight 5/2005.

Custom canopy 4.2g instead of stock 15g. Unlike metal pin retainer, supermagnet tears free cleanly during a nose-in (proven).

Weight budget (grams):
175 : fuselage, with glass, epoxy, Polycrylic, aramid-stiffened spruce
135 : wing, with carbon tow, glass hardpoints, oracover, and shiny film
20 : FMA M5 ESC, Jeti JES 012 rx
73 : sp400 motor
20 : folding 6.3x3 prop, mount and spinner (stock)
4 : canopy, custom
67 : battery (Tanic 2s 1550mAh pack, 19A, 69x42x11mm)
13 : connectors, wires, rubber bands, etc
509 : AUW (stock is 520).

Static thrust test: 13.0A, 7.6V, 360g thrust 12000rpm (pitch speed 34mph).
Thrust-to-weight ratio is 0.7.


Version 2.1, maiden flight 10/2005:

Apogee 3s1p 1050mAh, 11A continuous
Castle Creations Phoenix 10 ESC
Ultrafly C/13/20H outrunner (KV=2050)
12.5A static thrust, thrust-to-weight about 1.2 to 1 on a fresh battery.

Prop must unload to under 10A in flight, since the ESC doesn't shut down or melt.

Firewall salvaged from a Braun espresso machine's stainless steel grounds basket. Maybe the caffeine residue makes this version fly best. It almost feels like a pylon racer.
