The only gaurentee with a RC Heli is a gaurentee to crash if you don't start off with a small, beginner heli. :)

The smaller ones are pretty stable and easy to learn, also pretty tough so they take the landing abuse pretty well.

WOW!!! That is pretty awesome stuff!!! I envy you and your skill

I tested it some more today. I made some adjustmens and hovered it in ground effect for a while. I plan fly more tomorrow. It looks very cool and sounds like a full size helicopter.

Wow, that looks awesome!

I see you got a new toilet seat too!

Sorry I had to... [rofl]

Hehe. I didn't notice that. http://discussworldissues.com/forums...ies/smile1.gif


I actually have thought of CNC-milling some sort of design in my toilet lid just for kicks.

lol how about an eject lever that flushes [rofl]

btw what kind of Aluminium are you using ?
AlMg or something along the lines of AlZnMg ?

I always like these threads, not always reply,
but man you got the skillZssss http://discussworldissues.com/forums...lies/cool1.gif

I used 6082-T6 aluminium for the main rotor head and tail rotor hub. I get large pieces of this alloy for free. It has excellent machinability. For the very thin parts that also need to be extra strong I use 7075-T6 aluminium. This is about as as strong as it gets for an aluminium alloy.

My newest toy - Yes, it's another helicopter.
 

Pictures galore!

I bought a scale fiberglass fuselage of an Agusta A109BA a few weeks ago, it was just an empty shell so I designed the internal bulkheads necessary to mount the components. I didn't want to do a conventional RC heli installation but instead opted for an installation that's similar to full size helicopters by taking advantage of the structural integrity of the fiberglass fuselage. This meant I had to custom make the main and tail gearbox power transmission. It worked very well as these fuselages are incredibly strong and it's a lot lighter than it would have been had I used the conventional method which wastes the strength by adding a standard RC helicopter to the inside.

I milled the rotorhead, main gearbox, tail gearbox, tail tensioner, tail rotor hub, tail pitch mechanism, and several other small drivetrain and rotor components from various aluminium alloys. The head buttom and the main rotor blades were 3D raster milled from oak. I use Discreet Plasma for CADing and Vectric VCarve 4.6 and Cut3D for CAMing.

It currently has a gyro to stabilize the pitch axis. I haven't flown it with the added stabilization of the gyro so that's going to be interesting to test out. I might add a roll gyro later on.

The helicopter has a rotor diametre of 1437 mm and is roughly 1:7,5 scale. It weighs 3300 g (7,27 lbs) which is over a kg lighter than the norm for this size scale model. It will gain a little weight in the finishing process.

It has flown briefly but I had a little accident and had to make a fifth blade. I'll probably try it tomorrow.

I am also building a bigger Sea King that will also have a custom made fuselage, 100% DIY.

Looks very nice.

You got some mad skills boy. Good luck when it comes time for first flight.


PS. I've always wanted to get a RC heli, but I'm to afraid of crashing it and wasting all that money.

Check out the E-Flight CX http://www.horizonhobby.com/Products...rodId=EFLH1200 Thats what I got for my first heli, the counter rotating blades make it more stable. Oh and make sure you get the beginners landing gear, it helped me a lot too. And the parts are pretty cheap, so when you do wreck it it won't cost you a fortune.
