Default 80" Extra 330 profile plane from Aeroworks

My friend and I are each building the 80" Extra 300 profile plane from Aeroworks. He and I were looking for something outrageous to put our YS 120's in. The kit was kind of a pain but the end result is cool.

I'll start covering this weekend. Except for talking to Aeroworks I have never heard ANYTHING about this kit. Does anyone out there fly this plane?

We are building one full span at 80" and the other one rib shorter at 73"

Sounds like a real riot!! Do you have any construction pics to post? How did you like the kit? How were the instructions?

Default 80" Extra 330 profile plane from Aeroworks

This instructions are terrible. They're just photocopied typewritten instructions that do NOT always match the plan. The plans dont match the building instructions 100% either. In fact, we called Aeroworks a couple times during the framing process. When asked about better instructions and current plans, they said they only sell a dozen or so of these kits each year now, so they will probably do nothing.

No big deal. the planes look like they'll be a HOOT. And plans and instructions notwithstanding, they ARE really well engineered and they're light. They tout this one as "the King of Fun Flys". On the YS 120 these will come in in the 9 1/2-10lb range. Not bad for a plane with 1600+ square inches of wing!

I will post pics of this framed plane when I get home this weekend.

cheech, I have this plane with a os 160 on it. at 11lbs it flies great ! if yours is under 10 lbs it will float forever. there great for hovering and any 3d moves.

Default Fun Airplane

Mine had a Moki 180 glow engine on it. This was just about too much engine. As you say, they are engineered very lightly. After a couple hundred flights, my wing broke in two and folded up like a butterfly. plane was destroyed. But it was much fun while it lasted. The only member carrying the wing load thru the fuse is the spars - they were balsa as I remember. I would be tempted to reinforce the wing center section where it passes thru the fuselage if you can. Also, I broke a horz stab in to right down the middle on one of the very first flights. The covering kept the tail together enough to land. I rebuilt the stab with one size larger (thicker) balsa.

You may not have any trouble at all with the 120 size engine. But go easy on the throttle.

Default Did not use flting wires

I did not have flying wires on my plane. This would have prevented the problem. I would recommend flying wires if you go with a big engine.

Thanks. About your broken stab, did you have flying wires on it? It DOES seem flexible and flimsy.

Looks like way cool fun!!! I've been looking for something with big wingspan that is a fun fly. I'll be real interested in your flight reports. Thanks, and best of luck.
p.s. Has anybody put a gasser in one?

Hi All,
I'm very slowly building one of these too.
I have modified the horizontal stab with 1/16 I-beam type construction. Very rigid at minimal weight penalty.

http://www.geocities.com/crazyherb2k/horzstab3.jpg

Also, I'm building it for an RCS 1.4 GASSER.
The modifications were easy for the rear mounted carb of the 1.4.

I've also added 1 inch pink foam under canopy area for strength where I grab it the most.

Cheech your's looks great!!! Give us a flight report when you get it up!!!


High Flights!!

Default 80" Extra 330 profile plane from Aeroworks

The first of TWO of these that we're building was completed yesterday. The only issue to address before it's ready to fly is the CG. Aeroworks said it need to CG on the spar and that we could expect it to be NOSE heavy with a YS 120 on it. It came out a little tail heavy. By adding a hub to the engine crankshaft, moving the engine forward about an inch and moving the battery way forward in the wing root, it WILL CG without adding weight.

This plane is the full 80" one. The next one, done in a couple weeks, is clipped-wing at 74".

All up weight of the 80" one is 9 lbs, 14 oz.

Default clipped wing xtra

i cut my wing down to 62" and like it even more. the roll rate is to slow with the 80" wing. the plane was built at 80" to be imaa legal. if you really want to do the 3D stuff try the wing at 62" thats 3 ribs in from the tip's. also i fly mine with a saito 150, 16x8 apc and 30% heli and the os f plug. 2 sets of flying wires on the stab. what a *****in' slow rolling harrier it does. just some thoughts.

Default 62 INCHES!!

WOW!

That almost makes it worth keeping a ONE PIECE airframe!!

Think 62 inches will still work decent with a RCS 1.40 gasser swinging a 17x5 prop?

Cheech you get that thing off the ground yet?

High Flights!

Default 80" Extra 330 profile plane from Aeroworks

Just got the first of two of the Aeroworks planes flown today. All I can say is W-O-W! This thing does it all. The first plane finished was my friends. Mine finishes in a few days. This was a joint project to build two of these.

The YS 120's we are using seem PERFECT. Power is ridiculous. The plane hovers all day and can rocket vertically out of a tailsllide. We CG'ed this one about 1/2" aft of the spar. Again, WOW!

All up weight on this full wing 80" one is ten pounds . Mine is clipped to 74". I'll weigh it when done.

CRAZYHERB, I have tried many times to get to the URL you have a couple post up. Is the pictire available somewhere else? The stab & elevator could use beef and I wanna see what you have done.

Default 80" Extra 330 profile plane from Aeroworks

i have a friend in taft california who has one with a moki 1.8. he also tried the wing at 62" and raves about it now. the first one he built with the full span wing crashed when the wing broke. i flew his in phoenix last month while we were all there for the gold cup. i noticed little differences from mine to his. the rudder servo must be fast. i have hitec 945mg's on mine and have no trouble with authority on the control's. after all this xtra talk i think i'll go fly mine today. ttyl RR
