This is the former group and keel for a new 3.3 meter rotorspan
ka50, and will be all carbon fiber/nomex/carbon sandwich
construction. A very straight piece of 3/4" hardwood marine grade ply comprises the keel, and mdf formers. The fuselage
is 11 feet long.

8 pound density foam is next. The windows are all
flat, which simplifies the canopy/scale cockpit layout.

Michael,

this will be impressive. Same mechanics as KA 52 ? Any progress on the KA -50 shorter version (2M40 ?).

All new much larger mechanics, with a new 15 kW turbine...and the ka50 is flying very well.

Do you have any pics of the fuselage of the Ka-50. The only ones I saw were the fuselage of Ka-52. Thanks

The Blob

From yesterday, the wood frame was completed;
foam filled today.

(On the left is the 3.2 meter carbon cobra fuselage.)

Fredd...this is it, such as it is yet...ka50 and coax trainer
were being used synonymously.

Hi All,

Here are a few more new pictures of the KA-50 build. I've been really busy sculpting this sucker, not much time for photo's.

More pics to come...

This is a new technique to me - pouring foam between the formers.

Can I ask what particular chemicals your using - I guess it must be a 2-part mix ?

What sort of tools are you using to shape the foam ?

Really interested on what your doing here - superb work !

KA-50 Build

The foam is BJB TC-300 two part urethane mixed 100 to 100 by weight. It yields a 4 pound density rigid foam that carves like butter.
As far as tools go, I used a claw hammer, chisel, hack-saw blades shaped into various loops, and just started hacking away at everything that dosent belong. Next I use various sanding blocks with 60 grit paper. This technique works well for me for roughing out the basics! You can utilize pretty much anything you like.

Regards,

Paul-

I've never used the pour technique. I've done the wood former/foam mix, but I've just used various hard foams and just cut them to fit between the formers. I like that, as I can remove the foam, and adjust that.

Rhett..... I can't fly, but the Profi sure can.

Thanks torque...

we place all the entries here in the turbine category, since scale
has all powerplant types....

More pics with complete clay layering, then the tooling and plug
surface detailing in the epoxy.

best,

m

Mechanics and fuselage

I will have a limited run of the mechanics for the 3.3 meter
ka-50 Werewolf, available only through the MTJ USA distributor, not germany.
They are ultra high end, full oil bath, full size aircraft quality,
and thus not inexpensive. They are for 6 to 15 kW turbines.

The fuselage is all carbon, dual layer, with nomex sandwich, ala formula
one quality construction, also ultra high end. It will be available in march.

PM if interested.

best,

michael

Almost completed initial clay lay up

More pics added, four posts prior....

The auto prototyping clay is heated first, hardens in
half an hour, and then is steeled and raked.

You can see your reflection in it when the tooling is finished,
as the particles are that fine.

Now for the scale template modelling and further conformal tooling.
