Here I'll add some stuff about the Mustang I'm currently building.

Here I'll add info about my V-Diamond.

This is the equipment and specs.

• Motor: KDA20-26M, KV = 1130 RPM/V; operating current = 4A - 13A; peak current = 15A (15s), mass = 43g, does not even get warm
• ESC: 10A OEMRC
• Prop: GWS 11x4.7
• Battery: FlightPower LiPo 7.4V, 800mAh (2C fast charge, 18C continuous discharge, 43g)
• Servos: 2 x HXT500 for ailerons, HXT900 for elevator, HXT900 for rudder
• Receiver: GWS Pico on channel 60
• Wingspan: 60.5cm
• Wing area: 0.129m^2
• Wing loading: 2kg/m^2
• Mass: 216g (airplane) + 43g (battery) = 259g (yes, all my airplanes are heavier than the specs...)

This is the equipment and specs:

• Engine: O.S. 0.46FX 2-stroke engine
• Prop: APC 11x8
• Servos: 4x Hitec HS-300
• Receiver: Futaba, 8-channel standard 72-MHz receiver on channel 55
• Wingspan: 155 cm
• Length: 137 cm
• Wing area: 0.44 m^2
• Wing loading: 5.4 kg/m^2 aprox
• Mass: 2380 g

This is the equipment and specs:

• Motor: KD A22-15M from HobbyCity (Kv = 1050RPM/V, 6A-16A, 20A peak (15sec))
• ESC: 18-A OEM RC for brushless motors
• Battery: TP 3S1P 2Ah Li-Po battery
• Prop: APC 9x3.8
• Servos: Hitec HS-55 for elevator and nose gear, and HXT900 for rudder
• Receiver: Hitec, 8-channel standard 72-MHz receiver on channel 60.
• Wingspan: 99cm
• Length: 78.8 cm
• Wing area: 0.1855 m^2
• Wing loading: 4.1 kg/m^2
• Mass: 760g. Yes, the airplane is quite heavy. I expected it to be 500g or so... Too beefy I guess. Too much spruce, 1/16" balsa covering on wings and fuselage sides, large battery, large receiver, thick pushrods, etc. Solid, but heavy.
• Simple static propulsion test: about 15A, 160W, 8400 rpm.

Current setup:

• KD A22-20L brushless motor (85g, kV=1000 rpm/V, 6A-21A (25A burst))
• APC propeller (9x6) and spinner
• Castle Creations Phoenix 25
• Thunder Power 2Ah Li-Po battery, 10C-12C
• Hitec 8-channel 72-MHz receiver on channel 60, with replaced antenna (same as stock antenna)
• 2x HXT900 servo (flaperons)
• HXT900 servo (elevator)
• Eflite servo (rudder)
• Hitec Optic 6 computer radio with Spectra module

Throws:

• Ailerons: +/- mm, 35% exponential, measured at the extensions
• Elevator: +/- mm, 35% exponential
• Rudder: +/- mm, 20% exponential

Performance metrics:

• Static current, full throttle: 22A
• Static RPM, full throttle:8000
• Flight duration: >13min, <20min
