Discussion Looking for Flying Aces Sportster plan . . .

planeman — Wed, 25 Nov 2009 02:40:10 GMT

I was working on assembling some scans someone sent me long ago of the "Flying Aces Sportster" when I realized I am missing a scan. As I don't recall who it was, I will have to rely on someone here to send me a complete set of scans of the plan so I can continue. If I can get them I will post the finished plan here on this site group for all to use.

Please sent the scans to this e-mail address: rufus.carswell@yahoo.com

Thanks!

..full of all that stuff you thought had gone forever..(and quite a lot that arguably should have, nostalgia excepted :D).

I've just done a complete makeover of the old Keil Kraft Halo, complete redesign, so I thought the 'plane pursuit' squad might be interested in what we still do.

There's a bit more here than is on the 'official' website at www.replikit.com. If you need help e-mail or PM me.

Discussion How can i apply dope?

qacermacer — Sun, 15 Nov 2009 09:13:08 GMT

The first plane i ever built was a Guillows Aeronica and lets just say it didn't fly at all. I later learnt that balsa free-flight kits need dope to apply the tissue properly and that they can sometimes be a bit heavy.

So can anyone tell me how to apply dope for my next project (a Guillows F6F Hellcat) how i can apply dope and any weight reducing techniques.
I think, because i'm not the most experienced builder, i didn't build the Aeronica very well at all so it didn't fly.

And one last thing-could anyone give me tips on getting all the pieces to fit because i found last time that alot of the pieces didn't fit together at all.

Discussion Free Flight Class Definitions?

Harri3 — Fri, 13 Nov 2009 20:02:39 GMT

Hi, I used to fly free flight rubber models while growing up and have been into RC planes for the past 20 years. I still build a few rubber models and visit this forum but am stumped as to how rubber powered free flight planes are categorized. I've tried the seach function without luck.

Can someone define these for me? (or point me to a website)

Peanut scale - (from the Peck-Polymers website I take it the max wingspan is 13")

Walnut scale - larger than peanut, but how much?

Pistachio scale - smaller than peanut?

Dime scale - ?

Embryo -

Jumbo scale -

Golden Age scale -

No Cal scale -

I'm sure there are more but these are what I can think of now.

Discussion Guillows Fokker D1 build

scigs30 — Tue, 10 Nov 2009 17:34:04 GMT

My Comet P-40 is almost done. I was at a class this week up north for work so I brought another kit with me. I was given a laser cut Guillows Fokker for my B-day. I am sure all of us remember trying to build one of these as a kid and ended up with a non flying brick. Well I can say this kit is far superior to the kit I had 30 years ago. The wood is still on the heavy side for a triplane, but still a lot better than the die crunched stuff. I took my rocky top jig with me and started building. I was inspired by Supercruisers Fokker restoration, so I wanted a little nostalgia. I will once again use Testors cement, since that was the glue I used before Elmers as a kid. I will also use the red tissue in the kit and all the parts. The only mods might be to beef up the landing gear and move the motor peg forward. I was able to build the fuselage in just one night. The parts fit perfect and by far the best Guillows kit I have built so far.

Discussion P-51D build

draganbt — Mon, 09 Nov 2009 18:33:31 GMT

Hi :)

Got my hands on some balsa(finally), and here goes my first balsa build. Decided to make it a Mustang since its my favourite :D Its an Earl Stahl P-51D Allan Hunt design, 20inch wing span. Started off with the tail, and cutting the wing parts. The tail is made from 1mm balsa (dough the plan said 1.5mm) but I only have 1mm and 3mm sheets. The tail ribs are from basswood to compromise for the loss of strength from using slim wood (not exactly sure if it will add the needed strength, but I'm giving it a try :D ) I'll keep you in track as I go along

Cheers,
Dragan

I found some really cheap gold and silver metallic tissue at my local grocery store.

Any ideas what the golden tissue could be used for?

Discussion Measuring Wingspan

Twisted Sheets — Fri, 06 Nov 2009 23:22:14 GMT

I am building what is supposed to be, an 8 inch wingspan FF glider. The three pieces of the wing are actually almost 9", but because of the angle they are supposed to be attached at (dihedral), it measures 8.5 inches, tip to tip.

If I want an even 8", do I angle up more on the tips, or cut off 1/4 of each center section of the wing, or shorten the tips.

Such a simple little plane. So many questions.

I am assuming that wingspan is measured from tip to tip?

Discussion Dope over foam (any and all types)

BillHones — Thu, 05 Nov 2009 20:54:34 GMT

hello! so i have a question. has anyone every tried to put either butyrate or nitrate dope over foam? any type of foam... i have an alula slope glider coming and im thinking of trying to cover it with jap tissue or silk span. im no chemist nor do i have any foam to play with... er test ;)

Discussion Electric Free Flight?

skyline223 — Thu, 05 Nov 2009 02:42:07 GMT

How would you go about doing an electric free flight model? Not RC, but simply substituting an electric motor for rubber bands. Of course this has been done, but I simply want to know what setup you guys are using.

Discussion Garter Knight Build

Snorks — Sun, 01 Nov 2009 17:59:17 GMT

Finally I have the time for a build! I've had the plans for the garter Knight some time - from X-List. I built the vertical stab today, after laminating the outline last night.It still needs some final sanding. Prop blade also needs some finishing sanding.
Will domestic tissue from the grocery store be OK to cover with? I think it's jap tissue(ish) -it has a shiny side, which I believe should should face inward when covering.
Plan is full of errors, which I don't think is from the copy machine. the base rib for the stab on plan for example is 1/8" shorter than the side profile. The prop block is also shown much longer than the actual size.

cheers

Discussion Prop Speed

Twisted Sheets — Sat, 31 Oct 2009 21:42:59 GMT

On a Pennyplane for instance, why does the prop spin so slowly and the plane just floats along.

Is there some kind of "speed limiter" that the prop is attached to? or is it just the rubber and a bearing, and speed determined by the amount of winds and the shape of the prop?

Thanks.

Discussion What to do with these....

Hemikiller — Fri, 30 Oct 2009 12:53:17 GMT

Looking for a little advice here, I'm helping a friend liquidate his father's modeling estate. Since I'm mainly R/C, I really know very little about free flight stuff. He has at least a dozen various ships, ranging from small 16" w/s balsa gliders, 48"~60" built up jobs and at least three gas free flight in the same size range. All of these are nicely crafted and in excellent condition.

What would the best venue be to offer these for sale?

Discussion Guillows Aeronca

scigs30 — Fri, 30 Oct 2009 05:54:22 GMT

Well I am building a Guillows Aeronca straight out of the box. This kit has ok wood as far as weight is concerned but it is die crunched. I am going to build this kit with everything in the box except I will be using a Guillows 6 inch prop and tan rubber. Since the wood is crushed and porous I am using Testors Cement instead of white Elmers.

Discussion Single bladed folder

Snorks — Thu, 29 Oct 2009 19:23:30 GMT

I'm carving my first single bladed folder for a "Garter Knight" ( AM plan D809 to you). I'm quietly confident so far with the carving of the prop, I'm just wondering how thick it should be? at present it's about 4 or 5mm. It's a 15.8" diam & 26" pitch. It's only going to be a sport model for my own pleasure. Does a thicker flat bottom section cause less drag than a thinner undercambered blade. I think Applehoney once stated that a flat bottomed section was fine.
Question is... is 5mm too thick for the 8 inch blade. I've never seen one in the flesh & all the plastic props I've seen are quite thin all the way through the section.
will post a pic just now, also wondering if it has enough twist?
I've followed the plan faithfully.
Just tried to take a pic... but it's almost impossible to capture accurately- because the viewer doesnt know where angle of the root of the blade is in relation to the angle at the tip. I have a pitch gauge shown on the plan.

cheers
Simon

Discussion Prop thoughts...

Gluehand — Wed, 28 Oct 2009 14:59:38 GMT

I beleive we all admit that a folded prop induce less drag than a non folding one, so let us omit this factor right from start...

The question:
On a rubber model: Does a frewheeling prop generate more drag or less, than a non rotating one...?

Undisputable, an autogyro falls faster should the rotor stop rotating, but still most rubber models have a freewheeling prop setup....:confused:...so, could anyone please bring some light into this...?

I know, a rubber prop has much higher pitch than an autogyro rotor....but that doesn't give the whole answer....

Discussion plans

draganbt — Tue, 27 Oct 2009 15:55:18 GMT

Hallo

Been thinking about building a bigger glider now, and I want it to be a free flight glider, but I have no plans... maybe someone can email me a plan for a glider similar to the ones on the picture(don't know for sure if they are FF, but the size and general looks is the idea). A free flight glider plans with no RC whatsoever... maybe a timer, but that doesn't make any difference

Cheers,
Dragan :D
