Oh dear! I found the wingspan somewhere in this thread and my plane came out about 10% smaller than intended. Well, as usual I did the cutting before the checking, so I'd better build it anyway.

It's just under 32" WS. I want to use it outside on calm days so perhaps the higher wingloading isn't even too bad. Proportions seem to be OK.

If and when it flies I'll let you people know about it .

Hi Petyr,

just printed out the A4 tiled version and it comes out spot on to 35" span and 30" length for me. The sheets are to be lined up edge to edge which means a little of the plan will need to be hand drawn where missing from the print margins. I will eventually figure out how to add some indexing marks and give them some overlap. Just make sure Adobe is set to A4 and not Letter as it sometimes does and select print with no scaleing and all should be well.

Tim is right. The wing span is 35", and the fuse is 30" long.

Yes, a CDRom motor will be fine for this plane.

There are few pics of it in my blog. Scroll down a lil.

Tnx for the replies. I'll finish the plane anyhow, it looks to good to throw in the bin. I'll check Adobe printing or try using a plotter at work to print full size on one sheet: Cuts the cost of cellotape as well .

I'm looking into mounting the motor now. I didn't see too wel how you people do it. My CD motors are stick mounted (CF or Al) and I don't really know where to glue the stick. I'll study the pics a little more. I'm really new to this, sorry when I'm asking the obvious .

Don' be sorry, bro. If you don't ask, you'll never find the answer.

Check this post by fwilly and see how easy it is to mount that lil motor.

Tnx agn. Good pics, no further questions (fer now, that is.....). Talking about obvious...

In the mean time I assembled the best part of what's to do. No paint. Did stiffen the wing by laying a strip of .1 mm prepreg on either side of the wing with a bit of tape over it. Not too much weight I think and the wing is very stiff in bending now. No CF at the TE and 1 mm CF at the LE.

Torsional stiffness could be better so I'll need a bit of wire I guess. If it'll fly as well as it goes together I'll be very happy .

I wouldn't worry about that, bro.

The first version didn't have CF on the TE, and I didn't like the results. But with the smaller wing span, it may work.

Only one problem now I have printed it out, I will have to build it as I don't like to waste paper As I already have a 3mm F3P underway I think I will build with 6mm for outdoor use and a 2505 Microdan 2S600

The CF prepregs weigh next to nothing and stiffen the wing nicely. I had them lyng around, so couldn't resist trying.

@ Tim

I intend to use my plane outdoors as well. 6 mm will get you one sturdy plane.
I found a smaller CD motor (just under 20gr) and might try this one. Will see if I have the right magnets for such a small bell.....

Oops double post.......

Plane assembled and hinged, no RC, no LG weighs 40 gr exact. Not too bad. Might get it flying at 125 - 130 g, no LG.

Hi Petyr,

sounds like you should be flying soon I live right beside the coast so our average winds are a bit more than most. I found that much under 200g and I cant fly them outside very often. My current workhorse is a 320g Whirlwind that does get a lot of flying.

The 2505 motor is 32g (including mount). But as I have a few projects already under construction it might be a month or so before I start.

Have fun

Tim

As I write this down we have winds in the order of 7Bft , 130 g might be a bit light in these condx......

Time to go slope soaring or find a good bar

Slow builder here.
Everything assembled, motor came out at 19 grams something. Whole plane weighs 94 gr ex batt ex ESC. I hope to finish at around 130gr, which should be ok I guess.

I do like sloping but I'll opt for the bar in 7 Bft . In the north we had up to 10 Bft, with some flooding.....

Finish the plane and wait for no wind days.
