C-105 Avro Arrow Replicas

Beefitarian · Post by **Beefitarian** » Tue Mar 08, 2011 11:52 am

Does anyone recall a group in YYC that had a small A.V.Roe museum in part of a building that had a hobby shop in it. I know some of their things ended up in the Calgary Aero Space museum. I believe that included a flying scale remote controlled model.

I remember talking to one of the guys in the Hobby shop who claimed someone in the area was trying to build a flying scale Arrow that would be piloted by a person on board. I wonder if they had started any physical structures or did it never get to that stage?

I remember reading a few years ago about a group building a 2/3 scale composite Arrow and I'm sure I saw pictures of the fuselage mouldings (or whatever you would call an incomplete fuse) but nothing's coming up through a quick googling. I'm guessing they ran out of money or motivation.

From what I understand a full-scale flying replica could ironically never be flown in Canada as it would exceed the max weight for homebuilts and nobody would ever bother trying to certify the thing.

Do they have full sized like the one in Toronto or Witaskawin?

The owner of the RC Hanger in Calgary built and flew some of those models for the movie and they are building a flying plane not full size but big enough for one pilot from what I hear it is going slow but still going on

Already been done before. It punched a hole in the tail of the Vintage Wings Harvard:

Good thing they had that yellow barrier to protect the crowd.

That's the place. Thanks.

Not sure it's the same one you are thinking of Beef, but they are building a 1/2 scale or 3/4 scale in YBW. I haven't seen it in almost a year but I doubt they are much more then half way done.

I only ever heard about it. Probably 8-10 years ago I would think there's only one so that is most likely the one.

fatflyboy · Post by **fatflyboy** » Tue Mar 08, 2011 7:01 pm

That is the one at YBW a friend of mine was just talking to him about it the other day about it and it slow they still have a lot to do but they are working on it give the RC hanger a call he is a nice guy and has some good stories

I was standing behind the harvard when that happened. This was to be its last flight before they installed the turbine engine. Was at the air show at CFB Borden.
came across in front of the crowd, banked right and poof gone. They said the model has cost some ridiculous number like $10,000

I'll bet the folks at The Model Aeronautics Association of Canada (MAAC) just loved to see that happen.

The Arrow Replica project is alive and well (Now known as ARROW II). In Feb. MDRA did the first structural inspection on the fuse and it pass with minimal drama. To update, it will 47 feet long weigh 7500 lbs at max take off and will be capable of 500 Knots with two people on board. More information and progress pictures can be found at Avromuseum.com For those in the area there is an open house the first Saturday of every month at Springbank airport where the aircraft is being constructed.

Holy cow

I probably should have said "full sized" in the title. That must be the one I heard about.

So what are they using for an engine? 500 knots sounds pretty quick.

If you look at some of the other pictures that were taken, there was a family right behind the Harvard, one kid in a stroller and one up against the fence. The vertical fin on the Harvard very likely saved somebodies life. When they replaced the vertical fin on the Harvard, they put a small black sillouette of an avro arrow there as a reminder.

That model probably cost a few thousand, not 10. It was a ducted fan. A turbine model would have cost about 10-15K.

I've seen a turbine R/C jet go down in a parking lot in Las Vegas .. right behind a minivan .. it set fire to the tarmac and the back of the minvan when it hit .. not pretty either, black mushroom cloud and everything fortunatley nobody was in the parking lot, they were all at a game at the stadium next to the lot at the time.

My understanding was that Transport Canada and MAAC had several meetings on the subject after the fact but I'm not sure what the upshot was.

We're using a pair of Pratt & Whitney JT15D's for power that will leave us just short of 1:1 power to weight at max take off. Top speed will be limited by intake design and skin heating not by the amount of thrust available. The aircraft is being purpose built for airshow demonstrations and due to its light weight and low landing speeds will be capable of landing at almost any airport with a paved runway.
