Setting up a Multi-Engined Electric Aircraft (F7F Tigercat)

If 1 is good, then 2 or more is better…when setup right!

We as modelers are collectors.  We’re always collecting something related to our awesome hobby, be it RC gear, kits, or the like (you should see my hardware stash, when I go to the hobby store, I usually buy things in multiples).  And of course we always have those kits we’ve stashed away for a rainy day.  A couple years ago, I received an ASM F7F Tigercat ARF kit.  ASM was a line of ARFs distributed by Hobby People and they made some really awesome and unique airplanes (mostly twins).  Unfortunately the company no longer exists and the kits are no longer available.  But, if you find one at some point listed online, they’re definitely worth a look if the subject aircraft interests you.

As an airplane I love the F7F Tigercat (one of my favorite multi-engine warbirds) and so was absolutely stoked to receive the kit!  I promptly collected all of the gear for it but was busy finishing up some other projects and so put it in the que for a later date.  Well, that later date didn’t seem to come until a few months back when a friend staying with my folks, who’s always looking for an RC project during his stays, offered to help get the basic assembly done for me on the airplane.  The last couple weeks I’ve been finishing up getting it flyable (hence some delay in my articles and videos 😉 ) and I thought that Continue reading

Hawker Sea Fury – 5-blade Electric Conversion

5-blades of Sea Fury Heaven…but it Takes the Right Motor

sea fury - pics 548The 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.

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, Continue reading
