Back in the day the RNZAF had a very rowdy air combat wing comprised of a bunch of A-4K Skyhawks. They were a pretty old airframe, but had been upgraded with state of the art electronics designed for the F-16. They were great air show performers, but never fired a shot in anger and our government of the day in 2002 decided to can them. Very painful for aviation enthusiasts, but in hindsight saved the country billions of $$$ over the ensuing years and helped us cope a bit better when the hairy legged WWFC turned up a few years later.

Anyways, in remembrance of the air combat wing, I built an EDF Skyhawk about 8 years ago and have my own little airshow from time to time. The model is done up as NZ2654, one of the TA-4K trainers. She's on her second motor and third fan unit. The modern 10 or 12 blade fans work really well and another resulting development is that they are much quieter than the earlier fan units meaning they are more user friendly for park flying and sound more like jets than an overamped vacuum cleaner.

Here's a recent vid of some park flying down at my local park. You can hear the difference in the fan units as the ground shots are with the older fan unit.
