trusted tablets The Hawker Sea Fury is one of my favorite propeller warbirds. I guess the simple yet elegant lines of it combined with the beastly (and exotic) radial engine and 5-bladed propeller just have a certain appeal to me. Though it came 2 years too late to support WWII operations, it had a nice stint in Korea; not to mention was one of the fastest single piston engine airplanes ever produced. So, it’s not surprising then that so many Sea Fury’s have adorned the course at the Reno Air Races.
A few years back, Thunder Tiger offered a small line of 1/7 scale RC warbird ARFs that were quite nice. The lines of the airplanes were good and they flew incredibly well. The kits included the Sea Fury (military and September Fury racer schemes and the best looking Sea Fury ARF out there for some time) and an F8F Bearcat (military and Rare Bear racer schemes). I was fortunate to acquire one of the Sea Fury kits when they first came available and of course it had to be electric with a 5-bladed prop! So, I thought I’d use that to talk a little bit about designing an electric propulsion system for your propeller airplanes. First off though, here’s a little video of my Sea Fury in action, 5-blade prop and all! 🙂 It sounds just as good in person, no sound system needed!
The power system for the Sea Fury is as follows:
- Motor: NeuMotors 1515/2Y with 6.7:1 gearbox
- ESC: Castle Creations Phoenix 110 HV
- Battery: NeuEnergy 10s 5,000 mah Lithium Polymer
- Prop: Zinger 16×14 prop (aluminum hub with wood replaceable blades)
In sizing an electric power system (we’re talking propeller airplanes here as opposed to EDFs), the first question to ask is “what do I want my power system to do for the airplane?” What I mean is, click here Continue reading
