i made some floats from bubble tea straws. (1/2" diameter drinking straws)
they looked nice and to scale. the vapor floated in my sink and was able to take off and land from pavement. Tried a take off on water and did a nose forward and ended upside down in the water. I think the gear holding the floats spread and then the front dove into the water. After 20 seconds i was able to recover the submersed plane. A few minutes of blowing it off with my mouth and the hairdryer and I was flying again. I then tried building some floats out of pipe insulation. they didn;t look pretty and I didn;t dare try a water take off again. I thought I'd let a seaplane expert figure it out before trying again. Maybe I'll try the straws as skiis in the winter.

Try in shallow water.. IE: only deep enough that if it noses in, the prop spinner gets wet and hits bottom.. much like a glide test, there's a safer way to test a float vapor :P

Do you have some .025" carbon fiber rod? You can repair broken landing gear or pretty much anything on the vapor. Use a small piece of carbon rod and make a splint. Then wrap unwaxed dental floss around the broken area. It doesn't take much, just a few wraps. Then soak it in CA. This is a very strong repair and light too. I have fixed my gearbox in two places, my main wing in two places, my new tail dragger is attached like this, my landing gear is attached like this. I can post pictures if you want me to.

Wow Ched, that would be a great post with a couple of quick pictures. I guess I'm off to get some carbon rod. Thanks so much for the help.

That looks really good. What did you use to paint it? Sharpies?

I forgot to take pictures of how the GloPaint worked. Company delivered quickly so put green on one side and red on the other then installed UV leds. First roughend the outside of the leds to make them more diffuse. They do work better now, but the glo paint is a bust. If I zap it w/a camera flash it glows quite well but doesn't last too long, maybe 10 minutes before the green is too weak for good in-flight viewing. W/ the led illumination, it doesn't really glow much at all, looks like it did before I painted it up. Need to find a better led and research the light frequency that stimulates emmision best (sounds sexy?).

What a drag! The UV LEDs aren't really UV then? I thought it would glo like crazy.

Hey Ched!

Lots of good tips there on Vapor weight reduction. I removed the battery tray earlier and just that small weight difference was quite noticeable in performance.

Have you missed the prop spinner in terms of crash survivability? Or perhaps you never crash!

If you get a chance, I'd appreciate a photo of what you did to the wing ribs/braces/whatever you did. I'd hate to trash my perfectly good Vapor cutting away the wrong place or cutting too deep! Plus you have some flying experience post-modification to know that what you cut off that did or did not matter after all.

Thanks!
Jim

I cut half the wing braces away .25 grams. I replaced the wire tail dragger with a carbon fiber one, saved .1 grams. I replaced the wire wrap that holds the battery wires to the fuse. I used unwaxed dental floss, saved maybe .03 grams there. I made new landing gear that saved me .1 grams, not worth the trouble but mine broke anyway. I can use a 50mah havoc heli battery that saved me another .85 grams! The easy ones are the prop spinner, battery tray, wing ribs, and that is about a gram.

I think I crash more than anyone. I have broke two props, broke my gearbox in two places,and broke the end off the prop shaft. Would the rubber spinner save me some damage? I don't know, probably some of it, but I don't care. I won't put it back on. I'm at work now. I can post pictures later of all the weight reducing mods.

Wrap the broken area in unwaxed dental floss. Then soak it with CA. (super glue). I think I will start a vapor repair thread since I broke mine in about 10 places now.

I believe that mylar balloons will seal somewhere in the 200-210 degree range. I've used a sealing iron on old mylar balloons and been able to make a good seal with it.

Robster talked me into cutting part of the wing ribs out. I have not missed them but it was scary cutting them out, knowing I couldn't put them back. His post is on this page with pictures. http://www.rcgroups.com/forums/showt...=888584&page=3
