Hawker Hotspur - AR6400


I'd never heard of this Hawker prototype, so embarked on a bit of research and then a build. With having been kindly given an AR6400 receiver, this could form a great first build with it.
The Hotspur had a few interesting features. The gunners dome, which Boulton-Paul put on their famous Defiant, Henley fuselage and, Hurricane wings.

Specs:
Wingspan - 17"
Dollar Tree foam, paper removed, shape sanded
Receiver - AR6400
7mm coreless and gearbox
Spektrum skinny prop, original to the AR6400 after many others were tried
Battery - 1S 150mAh
Rudder, elevator, throttle
AUW - 34g

The build went well, though the intended ailerons haven't been fitted yet. 2 pieces of foam form an otherwise profile fuselage. The wings have quite a thin KFm2 step, which also adds rigidity, those are sanded toward the outer edges. Washout to the wingtips and wing rears, similar to flying wing sandings.
Initial flight trials showed lackluster performance, but, surely the original prop would be too long and skinny ? That prop was eventually refitted to the stock gearbox and everything was transformed...the difference was unbelievable. Before, it had struggled to remain airborne, needing gentle stick movements, but now it flew off without issue and very strongly. Good speed, sharp turns, will float along if wished.
The video shows that first real flight, a total joy in comparison.
Am very pleased with this Hotspur, which is likely to receive roundels, as well as the ailerons. Also, from a history of such things, am quite surprised that the Star Wars gunner dome has kept its guns throughout all flight trials !

Hawker Hotspur real maiden (1 min 54 sec)

No audio, due to being a Hubsan 2MP quad camera on a hat.
