Latest update.

I have modified the mechanics and test fitted to check the balance. The fuselage balances exactly on the main shaft. As you can see from the photos, I have lowered the tail boom, moved the tail rotor to the left hand side and reversed the tail rotor rotation. I will test fly the new configuration before installing in the fuselage.

John,

That's what its all about man,

"Scale Modeling" at it's finest right here, from the ground up.

Great Job,

Butch

Thanks Butch. I'm looking forward to the first flight which will be done before all the detailing and painting is carried out.

John:

Your project is right up my alley. I love to see guys doing scale birds that are downright different and even obscure. I am in the middle of a scratch project myself on a very unusual bird and have already decided on my next downright different and even obscure project

Fact is I have already cut a few parts from left over material from my current project

Keep it coming, it looks great!!Richard

Is it just me, I thought all Helicopters flew in 3D......Hmmmm?

Great job on that guardian. My buddy Rich built one from a mofified century seaking fuselage some years back. Wonderful project.

Here is the drawing showing the new side frame layout. I basically worked out where the output shaft for the tail rotor had to be. Then fitted another tail boom mount in that position. I made a new pinion shaft that reached from the original position down to the lower mount. The top mount has the pinion gear and two bearings. The bevel gears are mounted in the lower mount with two bearings. Depending on the layout of the two bevel gears determines the output rotation.

I noticed that the cockpit upper windows were too deep in height. I raised them 10mm and made new escape hatches. Needs a bit of tidying up. The cabin door is ready for windows and, insignia and stencils. The landing light housing on the nose is ready for the light to be fitted. It will look better when the screws are painted.
