That's good that it was very close to the ground and no other damage occured. I had a goof-up with my AS350 where I installed the removable blade (the one removed for transport) backwards. The spool-up seems normal, but maybe a slightly different sound, until you add pitch. Then the world closes in on you as you see your heli pop off the ground like a 3D flyer holding his heli and letting it rip with a full pitch pump. The damage was limited to a ply pad I installed (broken loose by the impact with the ground), and some minor rubbing of the tail pitch slider and the doghouse front lip. You would never know that anything was damaged unless you were shown the spots. If you remove blades for transport, mark the bottom near the blade grip so you can visually see when you have them flipped. Take care.

luckily i have spares of all the required cogs/gears.

i guess this is the opportunity i needed to pull the mechs out and weather my fuse a little more.

note to self: if you have a uh-60 dark colored fuse it will get hot in sunny weather. fly with your side doors open.
RCA / SF will have a complete set of steel bevel gears coming month.

That sounds like a plan. Do you know if they will re-fit the UH60 extended vertical tail drive shaft with a bevel steel gear?

I have done the unthinkable and added 450g of lead to the nose compartment in the uh-60 to try bring my COG forward.

Granted it's made the Heli sit correctly in the air now, but looks and behaves so damn heavy its crazy. and forget about flying her any kind of wind. she reacts really badly to wind.

Its more of a case of learning to fly and building confidence/trust in my machine back up again after so many damn issues. im very close. but do not like the weight issue. My tail now holds perfectly which is great.

She looked amazing in the air at the airfield today, But wasnt a pleasure to fly....YET.

Jay,

You can think about using a Helicommand it will keep your heli horizontal automatic (if you want that he do that) and it will gives you peace of mind.
He corrects the heli but you still need to fly her.

And you can decide in how much he helps you or totally not as I do with a flip on the switch.
I don't use it till I panics I hit the switch to enable the HC than the unit takes over, so its programmed by me in my Apache.

I have also a Hughes 500 Tow devender and there I have programmed the HC that the amount off stick input gives the Helicommand more or less stabilization in the heli and I must say its feels still natural when flying around but when it becomes to hover wile coming high and nose in it gives me more time to adjust and peace of mind.

However its YOUR heli and its YOUR fun of flying and how you want to fly it.

But I love the benefits of the Helicommand.
I use three of them.

Remember you still need to fly her but it will be easier (in my case in my head).

As you may understand now, I will and shall use every electronic/mechanical device to help my flying experience, its up to each of us to find what works best.

Just my personal two cents,

Jan,

Well today i took the uh-60 to the airfield and she flew well. even in a 10-15kt gusting wind. vibration issue solved, i had a bent torque tube. after replacing bearings in both the verticle torque drive, torque tube drive and smartmodel raised tail unit( on of the bearing casings inside the SM tail unit had completely popped open exposing the bearings, and on closer inspection, i think this was the cause of my chewed gears. i pulled out the torque drive and noticed it was pretty much poked. crazy.

the 450 grams of weight i added to the forehead fuse section has balanced out the heli well. i have slight tail control issues turning left, as in i dont really get the response im after, but right hand turns are now perfect. i will look closer at my geometry, but i think im 90% there.

when it is flying towards me, it looks so realistic and hulky, its just awesome.

soon i will have a video, and can put this build thread to bed.

Hello guys,

the helicopter looks very nice and fly great :-). Now I am finishing Aerodyne 600 Seahawk. I add the picture. For the real scale look I am searching the list of stencils (small technical signs) which are on the real helicopter. Are you somebody able help me with this? I add a picture of my plane with this type of stencils.

Many thanks

I have spent all day reading this thread. I have to say I am very impressed. I hardly get on RCG, but I was doing some research on this heli for my next build. I can't wait to get going on one of my own.

I will be bookmarking this thread to use for my own build. Thanks a lot Jay, Jan, Jose, and others that added to this. You have answered all my questions up to this point. I /know/ I will have more when I get started on mine.

I am also interested in pics of the insides.

Thanks,
Jimi

Welkom Jimi on this form.

What you just point here is the reason (as far I concerns) that we have this forum, to learn from and inform each other how thinks can be done or solved.

And as you may know there are a lot of ways to solve technical problems wile building scale heli's and it up to the reader/builder what he is doing with that info.

And in some cases you can get a friendship what go's further then a few posts on a forum.

Kind regards,

Jan,
