Aeroflyte Brolga 2

Has anyone had any experience with this 2 metre sailplane? I'm currently building my second one.

Have you had any other sailplane experience you can compare it to? Did you build it with the extra wing sheeting?

Any other thoughts?

Thanks,

Leon.

Yeah I did a few modifications to make sure the old girl wasn't going to blow up on a bungee.

I did use the extra sheeting, and I made sure that I had nice radiused corners, no sharp corners, as they're potential break points, I added some extra scrap trailing edge stock to the rudder to give me a little bit of authority, and apart from that, just flew her pretty much stock.

I've had a fair few 2m ships in my time, GL's, SL's, Tintara's, Super Turkeys (I've got super turkeys on the brain) and a bunch of OD's, and the brolga is a nice flyer. It's a strong little ship, but you've gotta keep it light, Aeroflyte always overdesigned their models.

The brolga is my first sailplane, I built it a couple of years ago and have only recently found an excellent flying site. The first one I built is completely standard with the extra sheeting. It seems to fly pretty well considering the hopeless job I did building it. The one I'm working on now is going to be much lighter. I've just about halved the amount of balsa in the fuselage, left off the extra sheeting and lightened the ribs. I want this to be a real floater. I'll use the wing from my first one for heavy launches, but I mostly hand launch anyway.

From the photos I've looked at the Brolga seems to be a pretty similar design to the Gentle Lady. How does it compare in flight?

Also I've been considering electrifying one of my Brolgas with a Cdrom motor and Lipo power. Could anyone give me an idea of what gear would be suitable?

Sorry mate, can't give you many ideas on what to expect in terms of electrifying it.

The GL is a little lighter, but they'll thermal like their a pidgeon pair.

Don't go too hard on the structure, make sure you leave in the good bits, like mainspars!!!

The brolga was my first sailplane, believe it or not built a little over 20 yrs ago, and it still flies!!

I have at different times used a power pod with a norvel .061 spinning a 6x3 prop for a gentle climb, so if you can get something to match that power preferably using a larger folding prop you should do ok.

Good luck,
Steve

I`ve got a Brolga . It was my first kit model . Took me forever to build & I went & busted the wing on its first flight , I was a shattered man but it turned out to be an easy repair . I always thought the rudder was a bit small for it & it had very poor penetration into a headwind . Most flights were off a bungie & a couple off the slope . I`ve still got the plane minus the servos . Maybe the Brolga 2 has got a bigger rudder .
I`d look at a geared 480 motor on 8 gp1100 or kan 1050 cells or even a 3s lipo .Geared 480`s used to be a common off the shelf item at most hobby shops & even used to include a folding prop . Not so sure nowadays though since the brushless invasion .

I think the 2 just means 2 metres. I've heard of a larger Brolga Aeroflyte makes, 3m I think.

I really want to power this thing with a homemade brushless setup of some sort, but since I'm new to this I'd like to get started with CD motors before I do any machining. I probably need to build a smaller plane to practice with.

Thanks,

Leon.

No, there is no larger brolga, it's an albatross once you go over 2m.

as for smaller planes for CD motors, I suggest you follow me to the foamies section!

much to chose from!

progress

Here's a horrible picture of the wing and fuse of my new brolga. Note the added lightness.

Looking good, but very light!!.

If I were you I'd add some shear webs to those spars!

Yeah I still need to put them in. I now have the vertical stab and rudder done as well. My servos should arrive in a couple of days so perhaps not too long before it's in the air.
