That is an interesting thought. I had initially conceptualized this model as all horizontally laminated, but then the idea eluded me when looking at the side profile. It could be done though. Will have to play with SketchUp and see what could be.

I'm very interested in seeing what you come up with!

I maidened my Stingray this afternoon and it went well. I am using a 2208-12 motor and a 900 two cell battery and it had good power. I didn't trim it any at all; it was just windy enough that I could never actually go straight and level long enough to figure what it was doing, but it flew well and landed just fine. 'Uncle Paul' had already left so he didn't get to see it fly but some of the guys he has made planes (yours) for watched and liked it. Can't wait to try it on a calm day!

Don,
The 2208-12 is a fab motor. It likes a 7x6 on 2s and a 7x5 on 3s is really powerful.

Just dial down the throws a little more and she will tame down, and that the CG is not aft.

Post a finished pic of your plane please.

I flew the S'ray in much less wind today and it did great. A few clicks of 'up' and she was doing fine. I am under ten ounces even with all that paint but I had to fly on half throttle and above. This plane is cryin' for a three cell battery! I couldn't find another 7x6 last nite so I put on an 8x3.8 and it felt ok. Yep, I need to get a few small 3s batteries!

Nicely done Don!

Once you get back to the 6" pitch on the prop you will need less throttle, significantly less.

I like the look of this plane alot. Would it suit an advancing beginner?

I have pretty much mastered my bixler and looking for something smaller and slightly more agile (without being twitchy) with good gliding capabilities and something that can be flown in light / medium wind.

Thanks

This could be a good second plane, but maybe third would be better. It flies great with no bad habits and is very controlable in some wind, but it does not have any dihedral so it needs attention.

Don't strip your Bixler; save it as a backup plane and buy all new gear for this new plane. You could buy one of Ken's kits, purchase the gear online, and still get out for about $60 or so and a few evenings of fun at the workbench.

My easiest plane to fly is a Parkzone Trojan T28. It is the plane I don't mind letting other pilots, even newbies, take the controls on. Dihedral seems to be the key to 'easy' or not. (usually)

I have mine trimmed to fly hands off, but you do need to know what to do if you get into trouble. It is easy to fly once set up, and on low rates shes a pussy cat, but crank the rates and go 3s, and you'll have your hands full.

Thanks Don,

I am a reasonably fast learner (was doing loops and rolls with the Bixler on its maiden, which was my first time flying) so i think it might be manageable. The only thing that worries me at the moment is my radio. It is the HK6DF which doesn't have dual rates or expo. I am waiting on a Turnigy 9X but in the meantime i guess i'll just have to go with minimum throws, smooth thumbs and hope for the best.

The bixler is getting a motor upgrade so i hope to be able to use the old motor for this next bird. I also have a spare 20A esc and some HXT900's which look like they'll suit the stingray.

I'd be interested in getting a kit but postage to Australia might be a killer.

Thanks Ken, sounds good. I really do need a proper radio huh

Could you PM me a price fr a kit shipped to 4127 QLD Australia.

Thanks, Oh and great job on all the help, plans and build threads you've done and contributed to. I hope to get some of your birds in the sky soon.

Ken, have you had a chance to work up a VLF fuse for this yet? I still think it might be cool to conceal the gear.

Not yet. Working on getting the Blu-Baby 33 Classic and Trike along with the Tucano plans published.

Bob's Flaming StingRay

My buddy Bob B. showed and flew his finished StingRay at the indoor facility this Tuesday. He did a cool black and red flame motif.

Looks Good Bob,

I flew mine yesterday and it did great; until I tried inverted and it tried to dive to the ground. It seemed like it didn't have enough 'up' (down) to keep straight and level. Does that mean it is nose heavy? I do have a quarter ounce of nose weight just to be sure it isn't tail heavy. It really is a fun plane on two cell and I'm gonna try 3 cell soon.

Don,
It does sound a bit nose heavy. It should balance on the center of the battery pocket, which is 3-1/8" from the front of the firewall.
