Nakajima Ki-43 Hayabusa "Oscar" 1/9 scale


Hello everyone,

It's been a very long time. I know, shame on me. I'll skip the excuses about life getting the overhand and go fast forward to what everybody wants to see and hear

Back in the stone age I designed this Japanese Bird. Someone I got to know through this forum asked me while I was in pilot school why I was so silent and if I got any new designs coming up. I showed him the Hayabusa (sounds way cooler than Oscar, no?) and he was immediately interested. I finished the plan, send is to him and as reward I got a short kit. Thank you very much Tony!

The plane is build up, like my other warbirds, from wood. Ply fuselage frame, balsa planking. Balsa build up wing and full balsa sheet tail.

Span: 1204mm/47.4"
Lenght: 916mm/36"
Weight, unkown but acceptable

For the first time, one of my designs features a hatch to remove the battery. I don't know why I didn't do that before, because it's handy

The prototype was painted in the colors of the personal plane of Satoru Anabuki.

Soon the shortkit will be for sale at Manzano Laserworks.

As there are some different versions of the plane, I put parts for 2 types of oil coolers in the short kit. The bubble canopy will be provided and on the plan there is a drawing of the unfolded square canopy.

Flying pictures


The plane flies very smooth and gentle. Due to some washout in the wings, you can steer the ailerons almost until the complete stall.
Because of the short nose, quit a lot of lead was needed to get the cg on the right spot. I feared that it would result in the flying performance of the Hayabusa, but except for a slightly less overpowered climb, you don't notice it. The wings are really huge and take the weight penalty without effort.

My setup at the moment is a Turnigy 35-36 1300 kv, turning an 8x6 prop. The batterypack is 3s 4000mAh, wich gives a nice 6' flying.

Best regards

Tom

Welcome back Tom!

The Hayabusa is looking good, as did your previous designs

Btw, how did the flight training turn out?

Hey Frank,

Nice!
2 questions,

1) What is it?
2) Did you build it yourself?

Looks sweet!
I still have a lot of fun in 'just' a Cessna 172 or when I go flying gliders

Well, it is an FK9 mkIV built by the German manufacurer fk-lightplanes.
And unfortunately it is not mine.
It is part of the fleet at Baisy-Thy (close to Waterloo)

I still have a lot to learn. Hope to solo any time now !
That seems to take forever...
Guess that is what you get when starting to learn at 50

What was the aircraft your picture was taken in?

A beautiful, and handy size, version of one of my all time favorites. I'll be checking for availability daily! Sigh... My return to scale planes is going to get expensive.

Thanks for the nice comments.

I'll let you know as soon as it is for sale.

Frank,
Nice, almost time to get wet after your solo
I guess that's a lot of fun as well. How long is the runway @ Waterloo?

The picture was taken in one of our company's newer 737's.

For the record,

The Hayabusa's weight, ready to go is 1644g, with a 3s 4000mAh battery pack.
This includes +/-200g of lead in the cowl to get the cg right. The plane handles it with ease. There is more than enough wing area to cope with it. But I should have been more carefull when building the tail. Every gram that goes in there triples or quadruples in front.

Baisy-Thy

Baisy-Thy - EBBY GPS: 50 34' 10" N - 04 26' 10"E

14/32
298m x 30m

What's the hold up here? Is this design going to be offered through Manzano Laserworks? When?
