Reply with quote

Hi Guys, this is my current project, have a few minor issues but nothing that can't be overcome, the first test flight was made with the front cowling removed, the motor I'm using is about 1mm too log and interferes with it, just waiting on a new motor. The test didn't actually leave the ground due to a failed bearing in the tail assembly.

It is a A2Pro 480 size kit, it comes mostly assembled with all mechanicals and no electrics, the unique difference with this kit is the belt drive from motor to main shaft.

Looks good Keith,

I like the raised tail rotor, that should overcome a lot of drift problems in lift-off.

Tom.

Hi Hal

Yes it is CP and it is Flybarred, and staying that way as it has an odd sized Main shaft inbetween 450 and 500 so there is no aftermarket parts that will fit. When I get it up and flying I'm going to do a repaint into Australian Army camo colours with the marking of one that still exists in a local Army Museum.

Begging the Admiral's pardon Sir, but.....

Is that Huey your Flagship?

With an angled tail, it's gotta be a belt drive tail rotor, yes?

Where is it ordered from?

What is the cost in Dollars American?

Thanks Collectively,

HAL

Hi Hal,

I suppose it is the Flagship at the moment, I also have a project going with a 500 Airwolf, which went on the back burner after a damaged control link caused it to crash through the Patio roof, I've only recently started flying the 500 again in the Pod and boom configuration. I'll probably finish it off after the UH-1 is completed.



Yes the HU-1 is belt drive, the kit comes with the metal tail lifter, which is a series of idler rollers for the belt and bell crank for the tail control push rod.

I bought it off eBay a LHS sold off their stock of large Helicopters due to lack of storage and cash flow, I got it for the princely sum of A$63 and A$50 freight that's a total of about US$110.00 including the black case seen in the photos. It then took about $300 worth of electrical to get it to where it is now.

Not sure where you would get one in the USA but here is a link to the website in France

http://www.a2pro-online.com/ not sure of the prices OS

Well, Keith...it doesn't look like there are any US vendors for your Bird, so my only alternative is to get a Huey as a RTF model from Amazon, where I have an account, even if it means having to live with that unpopular tail motor.

I do like Jack's Huey from his workbench picture...it looks well-scaled.

I guess we all have to make occasional compromises.....

Cheers,
HAL

Hi Guys,

The Huey had its maiden flight, lasted about 90 seconds in the back yard, actually beautiful to fly, very docile, had to land after 90 sec because of vibration in the tail. I believe that the vibration is comming from the fact that it's a big hollow body with nothing really supporting the tail boom, adding HD foam as support and will try again on the weekend.

May want to check the tail rotor for balance.

Hi Jack,

First thing I checked, it's OK, I think it's more a harmonic type vibration from the tail boom being unsupported, a pod & boom machine would have tail supports coming from the frame to about 2/3s of the way along the boom, this has nothing until right at the tail and then not very much, so I've added some shaped HD foam and see how that goes, if that doesn't fix it I'll try a bit of support about the middle of the boom as well.

Hi All,

Not quite the Maiden Flight but we will call the other one a pre-Maiden test flight, this is the maiden Videoed test flight.

Still having issues with the tail, will now remove it and check all of the components something is slightly wrong still, may do the repaint into Aussie colours while I have the tail out.

For a first test flight that's pretty good Keith. Sure you'll crack it in the end.

Tom.
