I have been looking arround and found some (japanese?) 3d planes that flys with the OS15LA but I´m not sure about an apropiate prop for 3d´n with that engine
look here http://www20.tok2.com/home/rc/

PD: My version of the plane is now ready to cover, VERY quick construction

Kewl, you have any pics? Did you get the dxf file for it? I'm gettin the file plotted to plans. As for prop, i dunno. Myself I'm going to put a 25bb engine on it.

Hi guys,

I'm also very interested in this plane. According to the sites I found they are using 9 x 4 or 10 x 4 APC props. I'm not sure though if these are the slowfly or electric props but a friend of mine will try out the normal 9 x 4 APC prop on his Lazybee to see if the os15 engine can handle it.

Kamlooper,
I've been trying to get my hands on the dxf file. Where did you get it? Could I bother you for a copy? I would really appreciate it. Thanks in advance.

This looks really neat. Pen-knife gone Japanese.

Got to have one - I have spent an hour in altavista translation services but can't find the plan!!

Where is it? I want to start today!

Funny how I started a thread about this plane months ago but no one responded..now everyone is interested in it. I dont have the link for the file but if you private message me your email address I can send it to you. File is too big to post here (even zipped). You cant get to the file link through the altavista translater, it messes it up somehow. You just gotta hit every link w/o translation. Also there some video of the plane flying, the person(s) flying it seem to need more practise, theyre all over the place

Guys,

Just in case any of you have Realflight G2, I have modified a copy of the Extra 300 profile with the dimensions for the Fun 15 plane. I would appreciate it if anyone would try it out and let me know if the dimensions are correct?

Thanks.

Might as well post the plans for everyone so that Kamlooper doesnt get flooded with emails.

Fun 15 DXF File

Have at it

Thanks MIL,

I tried opening the file using TurboCad and I've attached what I got. Is this correct? Looks like there are some missing parts. What CAD program did you use to open this file?

Thanks.

Thats what i got too, i used Autocad 2000.

DO NOT EVER use the APC E or slowflyer props on any sort of gas engine. They were not engineered to take the resonance from a glow engine.

Could someone tell me how to print the plans with deltacad? I need step by step instructions.......i'm cad illiterate..hehe.Im using a regular hp printer.

thanks

Paul,

So that means they were using normal APC props?

kamlooper,

Why don't you try Turbocad? They have a free version that you could download. And it will allow you to print full size plans into several pages.

Anyway, I decided to get some 9x4 and 10x4 APC props to test on my os15fp. According to one of the sites i visited, the 10x4 would produce 1.1kg of thrust and the 9x4 would produce 900grams thrust.

I'm flying a Quickie Bipe with an O.S. .15FP. I use an APC 8x4 prop and my buddy who built it and one for himself flies his with an OS .15FP and an 8x5 APC prop. The planes are quick with plenty of power and fly beautifully. My buddy has even take his off from grass.

Hi,
Master Airsrew 9x4 works great on a .15fp for a funfly use.
and don't break like the APC.
It's on a plane with no landing gear.
Total weight is 950 g ,possible to hover when the wind
stay home,but out of hover can be tricky.
Great combo.
Phil

Thanks for the interest,
Erwinf:
Tell us about thrust and also response when you finish your tests with the props.
I will try to post pics as soon as I put my hands in a camera

OK I got turbocad, now what....lol. I cant even print the ribs.

kamlooper,

I'm in the process of separating the plan into several files so that it will be easier to print them. I'll attach the files here once I'm finished.

For starters, I've attached a Turbocad file with the rib. Just open the file and goto page setup and it will show you a preview then click on print.

Hope this helps.

erwinf, thanks for your efforts. But the rib file wont open in turbocad.

Hmm... what version of Turbocad are you using? I'm using ver 6.5.

turbocad learning

kamlooper,

There's our problem. You're using an older version of turbocad. It seems that IMSI doesn't offer v6.5 for download anymore. Let me know if you can receive a 7.5mb attachment via email and I'll send you a copy of ver 6.5.

Just in case you want to stick with ver 4, I'm attaching a copy of the ribs which I edited with ver 4.

Hope this helps.

Thanks erwinf, that worked. At least I can get the ribs cut.

DanielZ, can you tell me what balsa sizes you used for building the fun 15? I assume 1/16 for the ribs, and 1/8 for fuse sides? 1/4 sticks for tail, stringers and 3/16 for spars......tho' i am just guessing.

kamlooper,

If you haven't started yet, the fuse sides are 1/32" with 1/8" stringers but you can use 1/16" for the sides if you want to strengthen it a bit. The ribs are also from 1/32" but again 1/16" can be used. The spars and tail are from 3/16".

Remember that the all up weight should be less that 1kg. 900g or less is recommended otherwise you won't be able to hover this plane.

I'm still working on the updated plans with descriptions of the parts in english. I'll post it here in dxf format once I finish it.

What is the wing span of the Fun 15? I just downloaded the plans and I want to know what to scale the plans to.
