You'll enjoy the T-Rex mechanic for a long time 👍

One of the most beautiful and detailed RC helicopters at Rotor Live

We call it POV. Thank you so much, Thomas!

The small details require a lot of attention, but ultimately they greatly enhance the realism. Keep it up, it will pay off in the end.

I'm very glad you liked my documentation and the result.

Thank you so much, Butch!

The arrangement of the displays looks fantastic. I'm excited to see the final result.

You need a second work table 🤷

good job 👍

Our Christoph Wegerl also has a talent for excellent videos.

I've received some questions on my post. Therefore, I'm going to write a short chaptered story.

I've made a total of three flights with the dampers. There were no vibrations or changes in flight behavior. The dampers also show no signs of wear. In summary, they work perfectly.

I've already seen it work on a Stefan Witte rotor head. I developed it for my 700 Roban rotor head, but haven't tested it in flight yet. I'll give it a try and report back.

I designed it in my CAD drawing program and printed it in 3D

You just need to mechanically decouple the potentiometer. Then the motor will run continuously. You can then adjust the speed using the potentiometer.

Nice exhaust ports

Thomas, the accuracy is described in the manufacturer's data sheet. I can also say that it is absolutely reliable. You can draw good conclusions from the amounts of fuel refueled after each flight. I don't offer it as a kit. But you can send me a PM. I'm sure we can find a good solution.

Wonderful work 🥰

This trolley is then lashed in the trailer

If you choose a trailer, you have to keep in mind that an empty trailer (except for the 25kg helicopter) offers no cushioning. For this reason, it is very important to dampen the helicopter itself against vibrations.

What do you think the final weight will be?

Can you show me how you attached the Insta360? I can see high frequency wobbles on mine.

Very nice precise scale flight

I just want to hope that the rotor blades have sufficient autorotation properties. In reality I have no idea but I will report anyway

Thank you very much Mark. Hearing such praise from an excellent helicopter builder is an honor

It's been a long time since I picked up the airbrush again 😅

Try with more expo first. Then you can find out whether your steering movements might be the reason.

Thank you

And looking forward to the end result gives so much motivation

Now I don't know what to do anymore. I'm so fascinated by your flat rivets. Should I attach solid rivets as planned or mill your flat rivets 🤯

yippee😁

fantastic idea💡

Are these flat rivets milled?

What material did you use to make the curved strip (picture 6/40) at the rear?

very nice flown 👍

Great. I would like to have something like that too 😊

At the beginning I tried a lot of things on my MD500 to get proper thermal insulation. It turned out that a double pipe was the most effective solution. Experience is therefore very helpful in reaching your goal straight away.

Very nice video and flown great. :))

It looks like this is the suction line to the pump?

I wouldn't use cable ties either.

I've also had problems with turbine stops in the past. For me it was the hose connection directly to the pump on the vacuum line. In my opinion, it is now very important to carry out all hose connections very carefully. Above all, do not use Festo quick connectors in the vacuum line. Take a look at...

Have you now found the error (the cause)?

You're right. There are many more options here. But first I would like to finally see the bird in the air 😃

The Insta360 GO 2 is already on my wish list for in flight movie 😁

Dad's a good idea. Then you can also see the animated display

I'll research what's available on the market

That would certainly work too. The Arduino has even more inputs. Here you only have to choose whether it should be a digital or an analog pressure sensor.

Hello Denis, what kind of insulation did you use on the exhaust?

great idea and well executed

First of all, I want to present a construction manual and of course the parts list as well. I'm still looking into the possibility of offering a kit.

presented very nicely

My throttle and pitch curve are absolutely linear. I assume that the upper pitch is around 8°. You have to try the maximum values ​​step by step

You can watch the flight behavior in this video. But there is still a slight nod that results from the poorly adjusted blade tracking.

I also fly a T-Rex 700 with a gear ratio of 8.2:1:4.54 and the Spin Blades, which are asymmetrical. The Roban head rotates in a range of 1300-1400. I fitted the Wren 44i which is also very comfortable at rpm output – 12,000rpm. At this head speed, the Spin Blads work very well. So for the price I...

What material did you use to print? How thick is the wall?

Very good your request. I have a wren 44i : Practical rpm range – 4,000 to 18,000rpm, 3.24Nm, 7hp (5.3Kw) (engine to max 195k rpm) After several turbine stops in the past, I worked very intensively on the fuel system. There is also a very good tutorial video - turbine technology for beginners part...

The biggest heli event I've ever seen. Best chief of flight line was Nicolas Aubert. His words: "Pay attention 4 minutes flight time is 4 minutes .. no more i had 120 helis in my back which are waiting to fly ... no stress"🤘🤣🤣🤣🤣🤣👍👍

Very nice scale flight

Blue

The heli is 2.38m in size and is expected to weigh more than 20kg. It's not what it might look like. Only the "Top Surface Skin Pattern" was printed here. I covered the original aluminum tube with it.

No on the contrary. It was just my big dream to build my first full scale helicopter. It's been taking me a long time and I'm not finished yet because I'm so in love with details.

Short description: The cockpit was created by myself using many pictures of the original. I had drawn it in detail and then 3d printed. I couldn't make upholstery for pilot seat (Bell UH-1Y) myself. It was a customer request to scale-print.de Stefan Radau sent me a drawing very quickly and made the...

Very nice setup
