A few pics of the foam Blazy Bee progress. Not sure if it is the same size but it is just like the one Richard flies. Fuse is nearly done and a bit of sanding left to do. I added a couple supports in the nose for the unexpected crunch and it didn't seem to add much weight. Not sure the size specs but I will post that next time. The next thing is shaping the wing and adding the wingtips. The material is all Dollar Store foam board with paper removed. Attachments:

Where "EXACTLY" did purchase the foam? ( which store) The stuff I have cannot be the right stuff as it has no 'paper' and will not roll easily to form the wing. the stuff I have is great for flat surfaces.

My Blazy Bee is more like the old timer Clancy Aviation Lazy Bee known for its amazing flight characteristics . this one has been redesigned by a club member .

I'll take the foam board! and will replace it as soon as I can locate a source. I want to finish off my Blazy bee that has been sitting idle for over two months in my workshop.

( which store) The stuff I have cannot be the right stuff as it has no 'paper' and will not roll easily to form the wing. the stuff I have is great for flat surfaces. I got the foam board with the paper removed so I cannot tell you exactly which store to get it at. I once had quite a bit of foam board that I gave away as I was working alot more with depron which was easily had......back then. Now I'm going to start hunting for some of this foam as it does build nice and in my opinion, doesn't get as much hanger rash like depron. Still have to be careful with it but it does hold up well. I'm going to start the wings tonight so I have to try rolling it to get the shape ? I'm definitely going to swear! Steve

Hey Richard, Is your wing 3mm or 6mm foam ? I recall it being thinner than the regular foam board. If I use a 3mm foam ( I have very little left) I think I can bend it easier. All my foam wings have been flat or curved made by cutting relief lines. Any advice on making the bends? Steve

The foam board Richard, Kevin B., and myself have been using for years is the 3/16" thick Adams Rediboard, which, with the paper removed, rolls beautifully and maintains it's shape indefinitely.
The trick is to start rolling it over a large diameter tube and gradually work your way down to smaller diameter tubes until you get the airfoil shape you want. Use a cardboard airfoil template to act as a gauge in determining the final curve of your wing section. The foam needs to be rolled beyond the final curve desired, as it springs back slightly when released.
Adams Rediboard used to be carried by Dollarama, but they switched back to Elmer's foamboard, which is far less desireable - the paper is much more difficult to remove.

Thanks Vic but Dollarama now only carries "Ucreate" foam board and it is completely useless for curved surfaces (I'll be bringing a sample tomorrow to our indoor flying). However it is great for straight flat surfaces. (no paper to remove). My problem is to find foam to make my main wing of my blazey bee. I have the body completely cut out and 90% assembled...just need that main wing formed and finish the electronic installation and I'll have another flyer.

I'd be happy to give you a sheet of Adams, but I won't be able to come to indoor tomorrow.
I haven't seen this Ucreate foam that you speak of. I'll have to check it out next time I'm by a Dollarama.

Don't worry Vic....Richard has offered me two sheets. My main objective now is to find a source of more foam, to pay back Richard and to build more planes.

A bit more progress. - Started the wing by making more foam ribs. I plan on making both the wings (Long and Short) and adding 2 more ribs on each to fit in the fuselage to prevent side movement. After I cut them out for the large wing, and after sanding I realized I probably don't really need them and certainly not 2. I went with one and will cut a keyway in the fuse to accept it. The more I think of it, the more rigid this wing is, the more likely it will break in an up-coming crash . - Added some carbon fiber from a kite on the leading edge to add strength and prevent the elastics from crushing the foam. I suspect I will have to add a small piece on the trailing edge for the same reason but probably just not the whole TE? - Never "rolled" a foam wing before except in a crash....(Ba - Dum - Tish) I used the advice from Richard, Kevin and Vic to start rolling on a large the medium then smaller tube to get the shape. By hand, I started with the large glass vase, then the medium Mac-Tac roll. I couldn't find a smaller tube but should have had one. It is very true that one should slightly over bend as the material will spring back. It turned okay and I was surprised how easy it is to bend and how far it could be bent without any heat as compared to depron. You realize the slight over bend also helps in proper glueing of the ribs on a wing that's not trying to "snap" back. - Next, sanded the wing ends flat and rolled the wing tips like the main wing. Kevin indicated that there is approximately a 10 degree tilt up on the tips so I sanded that bevel (That-Looks-About -Right-Method) and glued to either side of the main wing. I was not patient enough and handled the wing before they "set" and had to use some lightweight spackle to smooth the transition as both wingtips popped off with half dried glue. - This wing is almost done and will complete the smaller wing next. After that, tail feathers and electronics

And I did swear when the wing tips popped off. I should have tore them off and repaired properly

A bit more progress on the "Double B". Unfortunately I do not have any small servos left so I decided to get the painting done. I may have to tear some electronics out of another model to maiden on Sunday if the gym is open or wait till I get some. Either way the bulk of this small build is almost done. I went ahead and made a wing hold down that will use, when finished, one small screw near the rear of the wing instead of elastics. There is a "keyway" slot near the front that I have to duplicate at the trailing edge to keep it straight. Absolutely overkill here but tried something different. The front leading edge "saddle" was made by sandwiching some foam between 2 thin pieces of balsa then carving and sanding to fit the shape. It sits in snug but not too tight to remove for transport. I painted with the typical Blazy Bee design and added a small painted graphic from the Blazy Bee forum. I thought if my color choice was close to Richards it might be interesting to fly them at the same time to see what happens. lol . I used dollarstore masking tape for most of it because it has low tack however it was strong enough to pull a layer of foam off. I then used a tiny bit of heat to remove the remaining pieces and it did not mark the foam. Lesson learned. Added some white windows and a yellow motor mount with some black Sharpi marker for panel lines and outlined the graphic. The Sharpi helped in covering some paint bleed. Have to add some control horns on the tail feathers and install the push rods. Finish the wing hold down and I think I will add some wheels. Steve

Damn steve,
You're making my Blazy Bee look shameful.!! (not going to post any pics)
Mine is fully assembled and ready to maiden on Sunday if weather will allow

As you know, the camera always make them look better. I like this foam and I am learning more about it as I use it. It "works" a bit differently and is better in some ways than depron in my opinion. The problem now is to find out where to get it?? I hope we don't get the weather they are calling for on Sunday. Please post your pics. Steve

I hope it flys well. Its abit heavier than it should be. I'm going to add the wheels as my maidens don't always go as planned. Besides, I think it needs a bit more weight up front to balance . Steve
