I think the reviews below are the answer:
[Uses a lot of heat off the Iron to shrink.
Needs a lot of heat in the iron to work it,...Cardboard tube (although free) is very heavy and increases the cost of postage a lot.]
Foam needs a colder shrink to work like Econocote.

Another make which may be available to Dilz locally is called Profilm (from Germany). That's what I used on mine. |

is this the same as Chinakote (China Monokote)? Or is it different in some way shape or form?

There is some stuff at my LHS for $25 a roll, I can't remember the name, but it specifies that it has a low application temperature, I think it said between 60 and 120 degrees. There is another one there, I can't remember if it was ultracoat or profilm, that was $45 a roll. I'll check out the brand of the $25 a roll stuff when I'm there next. I still have the problem though that I wanted yellow and black, so I need two rolls which will be $50 - I can almost get myself a second hand DX5e for that much!
I think to go the more economical way, I'll coat the whole plane in yellow, and then just get some nice black tape for the bits I want to be black... I'm going to have to keep my color scheme a secret for now (so none of you bastards try to copy it!), but when it's done I'll be sure to show it off with lots of pics ;D

OK, just to stop the viscous rumors and endless sea of emails, I'll give you all a preview of the underside of my wing... As you can see, I probably won't be loosing site of this one quite so easily  . Attachments:

I just went down to my LHS to check out what they had. They carry two main lines of covering film. Solarfilm, at $27 for a 1.27x.7m roll, and Toughlon, at about the same price for a 2mx.9m roll. The toughlon seems to be much more rigid and stronger than the solarfilm, and it says on the toughlon packaging that it's application temp is between 58-121C, and it's weight is .27oz/sq. ft. I compared that to the specs of Econokote, NECubFlyer's favorite, and the weight is the same, and the application temperature is actually LOWER. It seems that this Toughlon stuff could be worth buying. I found a review on Toughlon here: www.rcuniverse.com/forum/m_2767655/anchors_3232072/mpage_1/key_/anchor/tm.htm#Do any of you guys have experience with either product? While I was there, I also checked out their carbon-fiber rods for a wing spar, they had 6/5mm and 5/3mm, listed sizes are inside and outside diameters. Despite the 5mm rod having thicker walls, the 6mm rod actually had less bend across it's length. The only solid carbon fiber they had was really thin stuff for pushrods. I was hoping to use a relatively thin spar so that I can keep a little of the dihedral by putting the spar in the top of the wing, and having it almost flush with the surface in the middle of the wing, and embedded deeper in the wing toward the tips. Since they didn't have any solid 3 or 4mm carbon there for me to test how flexy that was, I don't know how it would even compare to the larger hollow stuff. If I could find a smaller diameter solid carbon rod that were as strong or stronger than the 6/5mm stuff I saw today I'd go with that. Perhaps I should check out a different hobbyshop? I'm not interested in buying the rods online, as shipping is too expensive. |

I just made a diagram to illustrate how I need to imbed the carbon spar into the wing. See in the above diagram of a stock wing dihedral, that a straight carbon spar is going to poke out the bottom of the wing. By reducing the dihedral angle to about 1/3 (bottom diagram) , you can fit a straight carbon spar into the wing. This should hopefully be just right for it to be able to roll with ailerons, and still have some of the self-righting characteristics we know and love about our supercubs. Attachments:

You got way too much time on your hands Dill... :-)

I used monokote. 12usd a roll. It looked pretty good although my color scheme was horrendous. I ended up painting it all yellow and applying the OG red hz decals. It looked pretty good. Until, of course, I re-maidened her with a stripped servo. She flew high! And in circles! All the way to the ground!  The monokote came loose a little over the wing probably due to the angle in the wing. Where it came loose the paint also flaked. Doesn't look horrible though. I need to find some time to get her back in the air. I just spent all my money on a dx6i and phoenix flight sim. Soon I am buying a pz T-28 or a P-51 bl and an mcx s300. Somewhere in there I need to spend about $30 to get my cubby back in the air. Good luck with your build Dill! BTW, the all black with yellow stripes looks sick! I'm glad you could pull yourself out of that flood of emails wondering about your color scheme. Sorry for MY bit of obsessive emailing asking about when the unveiling was going to be. The fan club was really anxious for any bit of information I could find though! ;D I dig the black and gold though. Go Steelers! |

I hope the fanclub appreciates that I didn't get to respond to all the emails personally due to their shear volume. I want them all to know that I am deeply humbled by their dedication and support, and that it is greatly appreciated. I do not know or care whom the Steelers are, but I should clarify that it will be Cub Yellow, not Gold, which is about 2/3 bright yellow to 1/2 gold.... at least that's the plan. I'm still wondering if I should go black film with yellow tape or yellow film with black tape. I'm planning sort of a two tone, with black on the bottom and yellow on top. If I use black tape, I can reinforce the underside of the plane where it will get all scratched up with tape that can be easily replaced. OTOH, if I use yellow tape, I can get the highly-reflective yellow safety tape for increased night visibility. Any thoughts / opinions on what would be the better option? GO STEELERS! |

My cub doesnt right itself but i prefer it that way now as it goes where i want it to go (most of the time!) I flew mine fpv @ the weekend for the 1st time, scary! as my video link isnt great! You got way too much time on your hands Dill... :-) Looks good thou - but i prefer no dihedral. Yeah, plenty of free time alright.
