I do not remember when the last time that bolt was replaced. This bolt, P/N 053, is the bolt that is supplied with rotor head P/N 705/30 and is also used on the tail grips to hold the tail blades. The description has G-12 so would guess its a pretty strong bolt. The shank is not threaded so is the correct bolt to use in this application.
I wonder if the slop in the follower was the root cause over time. The follower have been replaced with P/N 68/20 which is ball raced opposed to the pins installed on the original driver. The bolt will be inspected and or replaced on a regular basis moving forward.

That is a classic look!!

Hello, there will be a "L" shaped foam installed on the carbon plates so the Lipo's can not touch the screw and ALu base frame.
Lookie what made it to the work bench today.
Scheduled maintenance.

I added pictures to this, but they are not there and there is no edit button. Iām not very good with computers.
Hello, I have 3 Vario scale helicopters. Since retirement, I can no longer afford the prices Vario is asking for their scale kits. I have had Roban before and was not fond of their kits, quality and virtually no part support! Does anyone know if their quality has improved? I had the AS 350 which ate belts and chewed up gears. I also had the 700 cobra which the gel coating on the outside...
Hello, I have 3 Vario scale helicopters. Since retirement, I can no longer afford the prices Vario is asking for their scale kits. I have had Roban before and was not fond of their kits, quality and virtually no part support! Does anyone know if their quality has improved? I had the AS 350 which ate belts and chewed up gears. I also had the 700 cobra which the gel coating on the outside started to peel off. Has anyone else had these problems? I want another cobra but have no idea if their quality has improved drastically.
Any tips would be greatly appreciated

Hi Michael, I reviewed one of the first models Roban made back in 2012 and I was concerned about the quality. They have definitely improved and there are many hundreds of satisfied pilots. I spoke to Michael Binder, Roban's founder and CEO last week and I can tell you that they are constantly looking to improve the product, keep up with demand and innovate. They will be a big sponsor of HeliStorm 2025 and you'll get a chance to meet them in person and see their newest tech.

Thanks Thomas.
Glad you enjoy the updates. I hope they are informative and with a little humor.
Thanks again,

I think that's part of the instrumentation package from test/eval. Other images don't have it. I have gotten the FLIR platform worked out, just need to figure out the FLIR itself. The challenge is that this is only a .30/550 size heli. The nose datalink antenna is only about 25mm tall.

This helicopter in kit form will be available and ready for pre orders very soon. The kit is primarily designed in the electric version for the experienced builder. Turbine version would be special order after customer consultation. It has been upgraded with improvements since version one was introduced many years ago. The 407 will be available next since it shares parts of the same mold. For more info use below email link.

Hi all. I am new to ScaleHeliPilot. I have recently bought the Vario Chinook 1:11 and I'm done with the mechanics. Fuselage up next. I have never cut fiberglass before so I am petrified :)
Other than some old RC scale cars (eg Tamiya) I have done in the past, this is my first journey into the world of Scale.

Hi all. I am new to ScaleHeliPilot. I have recently bought the Vario Chinook 1:11 and I'm done with the mechanics. Fuselage up next. I have never cut fiberglass before so I am petrified :)
Other than some old RC scale cars (eg Tamiya) I have done in the past, this is my first journey into the world of Scale.
I noted that Michael Kranitz suggested a step bit for the 30mm landing gear holes. I am curious though about the larger circular cutouts for the rotors. The instructions suggest 75mm and 90mm diameters for those. What is the best way to go about it? A dremel would work but it is difficult cut perfect circles with a rotary. I could look at a hole saw, but I'm worried that it might rip the fiberglass.
Curious to hear what other people did.
My second question is about sliding the mechanics in and out of the fuse. I saw Michael warned that one needs to be ready to do this a lot. It seems quite an involved process. Removal of the front rotor (and re-application of loctite after reinsertion?) And I guess the landing gear must also be unscrewed from the mechanics every single time? Is accessing the front landing gear not a pain? Because I assume the landing gear struts must remain in the fuse after the mechanics slide out.
I'll probably have many more questions as this proceeds. Looking forward to some great discussions here.
Christoff welcome to the Chinook world, I highly suggest you go thru this post.

Luckily I was able to place the lipo's next to the mechanics instead of in the cockpit, CG point is just fine now. Lipo's tray's supported directly by the metal frame, so no load on the fuselage.
XXL Helicopter Burglengenfeld Germany
While in Germany/Belgium we visited Klaus at his shop. He took us all to lunch and we spent a few hours drooling over the toys and picking his brain regarding some of his clever ideas he has implemented over 40 plus years. It was hard to not leave there without something,so a couple of the largest F model cobras available will be heading to the states.

Oooooh giant Cobras š sound dangerous!

Model line up
I am looking to build an old Marvelcraft Agusta A109s the I purchase so many years ago. I am trying to locate the specific domension of the front and rear landing gear of the full size aircraft. I want to put them in a CAD program where I can scale them down and then 3D print them for the heli.
I originally started building this in 2017. Due to the long landing gear legs, the tail blades and no good scale details, I shelved the project. I picked up again in 2023 due to 3D parts being available.
This was the original look from the build in 2017. I asked around if anyone had cut down their legs to resemble the TF Eggs. I finally decided to just do my own. It worked out but I had to swap the rear and the front legs due to the step. I mounted Dimension Engineering LEDās into the step strut step.

How frustrating is it to need a part only to be told you have to wait weeks or months to get it? Like you, I hate that, which is why Heliworkshop stocks THOUSANDS of parts so you donāt have to wait at a critical point in your build or repair.

At Heliworkshop, we are the only āstockingā Vario dealer in the USA with a strong emphasis on getting the parts or kits you need as soon as possible. Vario has a 5000+ parts inventory. Although it is impossible to maintain all 5000+ parts in our stock, we do our best to fill orders and ship in stock parts within 24 hours. If we donāt have the parts you need in stock, we simply add them to our weekly orders that ship from the German warehouse. Either way, we are always working to make sure you get what you need quickly.
Next time you think about kits, parts, service or just critical help with your Vario model, remember that we are builders with more than 30 years of experience building and flying Vario and other brands of model helicopters. We know what you need because weāve been there!
The tank cap already works. Now I can start with the hoses for the turbine.

Ha. I only drive about 20 minutes each way to work now.
When I was traveling for work, I would get through the city on Monday morning by 0600 so it was smooth sailing. 1 hour 6 minutes form home to TEB. 62 miles. Drive home on Friday at 1200 was almost 3 hours.
Military nomenclature stencils..
I had been searching for a company that could produce custom stencils in a very small scale that would work on models from 1/7 - 1/4 I finally found a company that was able to produce them. These are made from Mylar and are reusable. The price was quoted based on the quantity and I got 14 different ones which was about 110.00$ including shipping. These will work...
