Hydrofoam – land, water and air vehicle

Thursday, May 20th, 2010

As little I made RC boats from scratch and since my knowledge about air vehicles is bigger I just had to build another “boat” when I came accross LHydro-Foam. This “boat” has the same abilities as the ship in the Norwegian folk tale Askeladden, “Et skip som går like godt i lufta som til lands og til vanns”.

As usually I printed the PDF available on the French site and cut depron in given shapes.

F-117 Nighthawk project

Monday, August 3rd, 2009

After my last to planes I still had some depron left. I decided to build myself another plane instead of throwing it away or keeping it for repair scrap.

I had already came across a free pdf version of F-117 and the choice were easy. After transforming the pdf manual into paper with a little printer help, I realised the plane were to advanced. Which is not really necessary in my opinion. This resulted in what I would call a 50/50 build. I started the nose as it should be, but shorted the back down quite allot. I ended up only using the paper as line-up before adapting the pieces were I wanted them, using eye sight.

This plane is retired because of last crash due to it`s bad aerodynamic flight capabilities.

RC Extra300 project

Friday, March 20th, 2009

I’ve have been building this plane in parallel with the F22. Extra 300 is a free PDF-plane from rcpowers.com

The idea with this plane is to use a motor with variable pitch. These setups are rare and a bit more expensive than other powers systems. I will also have to install another servo to be able to change the pitch rate on the prop. 4D motor features a hollow motor shaft and I bought a set from hobby-lobby.com some weeks ago. The motor mount coming with this motor is designed for 3mm depron and I’m using 6mm depron. This is my first real problem on this plane so far. Will probably grind the front down to 3mm to be able to mouting the motor.

Update: the 4D motor were to weak for this plane and failed pretty quick. It`s now run as a pure 3D plane, even as this it`s way to flexible. I should have stiffened it of with more carbon.

Another mistake I did was making the plane in 105% size, 5% bigger than the orginal. If I were to build this again it would be 80%.

F-22 Raptor depron project

Thursday, February 26th, 2009

Two days ago, I managed to get my hands on 800x1200x6mm depron sheets locally. I only had to pay 207NOK or $30, if you wish. These sheets are god for 3-4 planes. I almost got two planes in one sheet where the Raptor was cut in one piece.

Yesterday I received my package from readyheli where there was two receivers and four 11.1v 850mAh kongpower batteries I tend to use on these planes. More on my second plane in another post.

Specifications for this plane will be updated when I deside the electronics for it.

Specifications so far:

  • Spektrum AR6100
  • 2200mAh 3S LiPo
  • HS81 MG servos
  • Graysonhobby brushless motor 2212-06 V2 2200kv
  • 30A ESC
  • 6×4″ prop

The plane is now dead after I dived pretty fast into a little forest.
