cd rom gws pico

if your ips motor craps out on your gws pico stik, try this conversion. everything is stock from the gws plane except the use of a cc10 and a homemade cd rom motor. 12neos nsnsns... 18(?)t, wye. prop is the gws 8043. weight without motor is 4.6oz. battery is either a kokam 2 cell 340mah or thunderpower 2 cell 730mah. with the kokam, flights up to 14min are common. it's never been flown indoors but i'm pretty sure it can. thrust to weight ratio is alittle above 1. landings are very easy. this is actually a plane i fly around when flags are wagging every with way. of course most of the flying in wind conditions is hovering.

Matt: It seems the different foams are a regional thing. In most cases, it's pretty expensive to ship foam overseas, or even cross-county, since the package size is so large. You should be able to find Depron somewhere in UK. Also, you guys have the wallpaper-backing board there which sounds good as well.

Here in the US, the common use for the fan fold foam is backing for aluminum or vinyl siding for houses. Not sure what they use there? Also, there are some similar foams used for a padding for hardwood or other flooring.

Finally, many guys have had to resort to slicing thicker foam boards into 1/8" or so slices using a hot wire rig. It's not too tough to do, I've tried it, and caught on pretty quick.

The real key is to figure out what the best locally available building material is, and then adopt a system for it's optimization in model size. For example, if your local foam is denser, chances are it's stronger, and can be sliced thinner... Or can span greater lengths without any bracing...

Did you guys ever do gravity slicing .... OFB showed me how ....put the foam block on the table , place the wire from the bow on top of the foam the distance from the edge that you want the thickness to be... ,letting the bow hang directly beneath .... turn on the juice ... wire cuts straight down .....pretty cool and so easy (for a change...)

That is the way I cut my blocks out. Works great doesn't it?

I'd have to have an awful deep bow to slice say a 10" wide sheet, though. May have to try it with some smaller (Bit-Size) stuff. My big bow is an old fiberglass kid's toy bow from long ago, restrung with wire. It's only about 10" deep at the center.

Jerbear has been slicing FF into 3rds for the wings and tails for out Bit-Size stuff. Works real well. I gave it a try the other day, and it's pretty easy once you get the hang of it. I just strung a wire and spring across an old shelf board, about 24" wide, and propped the wire up on a couple popsycle sticks and slid the sheet through the hot wire... Viola!

I use my wing cutting rig to cut sheets. It is a similar setup to the feather cut that is available commercially. In my rig the bow is pulled through by gravity rather than pushing or pulling the foam. I use steel rod (or music wire) as a template for the bow string to ride on. Works pretty well, it's quick and easy and they all come out alike.

Ahhh, what a nice day for flying! 2-3" of fresh, slushy snow, and no detectable wind

Flew 30-45 minutes on a 2s520 pack, stopping to do some trimming here and there. Most flying was below 1/2 throttle, hitting more for the tight turns, staying in the street in front of the house... And an occaisional loop or 3!

Realize, I'm down a prop size on this IPS... 9047RS on an IPS-A. Still, 1/2 throttle will still climb as well as my original stock LiteStik did on the 'specified' pack.

I did make a MAJOR CHANGE, which will be reflected on the updated plans. I added a shim to the front of the wing, to increase the incidence. I used 1 thickness of fan fold, skinned, so ~1/8", and it made the slow speed handling even better. If trimmed to fly level at 1/2 throttle, it climbs at full throttle, but not so bad it balloons...

I'll work on updating the plans in the next day or so, but it's not a big deal, since the wing is rubber banded on, a shim works fine.

I'm just extreemely pleased with the gentle flying and slow speed control of this one. Sure it'd be nice if it resmbled a 'real' plane, but it's closer than an IFO

Pouring down rain. Again.

Haven't had decent flying weather for 2 weeks. Time to buy a Blade Runner I guess.

Hang in there... We've had so much rain (after the 20" of snow melted, and before the current 2-3" of fresh snow) this week, that we had a 'Water Boil' Warning... Our local water supply got flooded, along with many homes and businesses. Now it'll all freeze, and talk about a nightmare!
