Laser Models Laser Arrow Delta Wing


Has anyone converted this? I'm framing it up now. Great laser cut kit. I'm using a geared 1409 2Y.

Actually, if this was spring and not fall I'd go glow on this also. But I have the motor already. It should do ok with 12 cells and a 10*10. Around 125 watts per lb.

If I get one I'd be glad to post it. Don't have a camera myself. But a few folks at the club do.

BTW, how was the build on the outlaw. The Arrow is amazing. It's like a 3d jigsaw

Its not too bad, its definatly different though. Lots and lots of sanding too. The arrow will be much easier and faster Im sure. are you using the way they have you set it up with a elevator servo and ailerons seperate so you can use a 4 channel radio? Ill prob just set mine up with elevons.

Not sure. Probably elevons. And yup, it is a quick build. Framing it will be just a few hours. Probably take me another few hours to decide on battery and motor installation. I'm thinking 2 to 1 on a 1409 2y , 12 cells and a 10*10 or so prop. That'l be 90 mph pitch speed and 63 ozs of thrust. The amazing thing is the wing loading should still be around 11 oz per sq ft or so.

I'd like to know how it does, I have a framed arrow hanging up. It has a wide glow engine selection, so a 45/3 should do great. I have a few other delta's though so I am thinking of converting mine to a stand off scale KFIR or RAFALE jet.

Well I finally got around to building mine, Had it done in about 2 days as it just fell together. I went with a Jett .50 angine turning a 9x7 prop at 18000 rpm The estimated speed using Spectrogram program from the sound file is around 145mph or so


Did you ever finish yours? got any video of it?

No, I never did get around to finishing it. It's number 2 in the Q right now. But that's likly to change at any time. But I really should get it done. It's all framed up. And I've started to install the servos. My hobby budget is all used up for now though. I do have a FX 40 looking for a home. Better than letting it gather dust.

Now to look at that video.

Very nice vid... thanks. Gotta love those high speed flybys

Its a very stable plane, when it is set in one of those fly-by's I can let go of the sticks and it keeps on tracking straight.

Name it, I've crashed it

Cue. That is a great video! Did you end up using just elevons and did you need to split the elevator to do it?

Also is the manufactures advertised 3.3 lbs weight the AUW with a glow engine? If so what do you think the weight of just the built and covered kit?

Sorry, Last question. I see that the airfoil is fully symetrical. Would you say that it is a thin, medium or thick airfoil? Want to plug it into ECalc for some tinkering.

Thanks guys,

Bill

Yes I just used elevons, the instructions have info on doing it both ways, no need for 2 extra servos though with elevons.
I used Futaba 9202 coreless servos in it also.
I just weighed it, 58oz with an empty fuel tank. I would say the airfoil is a medium one, its pretty draggy but with all that power up front you cant tell
