Hi Dag—

the Sikorsky is looking very good indeed. I haven't been much of a scale adherent but this has got me thinking. Congrats on flying the CP bird, which was surely an agile little devil. They are a lot of fun to throw around.

Merry Christmas to you, to Emma, and to your Lady.

Looks good, and I may be missing it, but you need some air inlets and outlets to keep everything from getting too hot. but it looks great. jim

THANKS!!!!!!

The weird thing on the chopper I flew was the throttle was in the middle, you never brought it all the way down for idle. It had a switch that gave you flight power. If you brought the stick all the way down it was for negative pitch (inverted flying).

I liked it, but took some time to get it under control. My buddy said I did great for only being around heli's for less than a year

Great buddy. I think if you can fly that beast in this confined space you can easily fly a 700 size helicopter outside.

Looks like a S-58 buddy!

She was a bit twitchy, my rates were way to high for a scaleish bird.......

I have to get the EII and the 36 done by SEFF, which I know the EII will be done, and I know the 36 will be taxing by then, but making this mold is not that hard, and as we have talked won't take much time once we know its scale.

Take care, and have a great New Year....

Damon a thought occcured to me on the S-58. I moght be able to sell a couple for you if you wanted to pull a couple more to the guys at the Sikorsky Archives. I know a couple guys there fly Heli and they might want to do a mod like this.

Yep. That's called 'idle up' and you did amazing for a first-timer. Here's me finally getting a grip on inverted hovering:

Yep....Idle up and stunt modes.. Think of it as "Head speed governing"...you want to maintain headspeed so the only changes made are in "Pitch" (Collective)
She's looking good though..Maybe a little (lot) more expo?.. My "Baby" birds like that a lot..

Today my Chaos 600 kit arrived and I did some measurements of the chassis to see what would fit best.

On the S-58 it was clear that (as expected) the main shaft would have to be much longer with probably an additional bearing. The chassis of course had to be redone (just the sides with my CNC mill).

On the S-55 the tail will not work out. But I think with some changes this could be done. Of course the tail would have to be modified. But I think it won't be too visible.

Damon, I send you the material tomorrow.

Hi Damon,

so this is how it can be done in the easiest way.

Take a Chaos 600 or a T-Rex 600 Chassis. The chassis does not have to altered. I went for the Chaos 600 chassis from scaleflying.com (actually scaleflying.de) with the elevated tail.

Here is what has to be changed:

* Tailboom of the T-Rex 700. But it has to be shortened by 59 mm. Also the torque tube has to be shortened accordingly. This is easy since the original torque tube can be disassembled.

* The elevated tail tube has to be shortened as well. Same with the short torque tube.

Thats pretty much it! The shortening of the two torqe tubes must be done most accurate since this is vital for the helicopter. It must sustain!

Since the S-55 has a two bladed tail rotor, no modifications are necessary. The shape of the tail blades can be modified for test flying. If they are fine, we can shape them to scale.

The main rotor head will be a three bladed system with 700mm blades (from the hole to the tip). There are some semi symmetrical blades as a set of three available but they usually turn right. We need a left-turning main rotor in order to put the tail rotor on the left hand side. Using symmetrical blades will consume more power but they for sure will be fine.

Cheers Alexander
