I replaced much of the heavy balsa with contest balsa. A also cut away a lot of balsa from the inside of the frames. The very heavy Guillows canopy was replaced with one made from sheets of thin acetate. The model is simply covered in domestic tissue that had been previously chalked with pastel chalk to make the colors more opaque. There is no other finish. I didn't use dope as this would have added a lot of weight.
Because of these videos, i have studied the 5 guillows kits my grandpa and i made and realized he needs perfection and put 2 glue bottles on each plane. So ive went out bought a spitfire and am building it myself i sanded down the part sheets and am leaving about 1/4 of stringers out, and cuting of excess balsa from large parts. Any tips? Did you dope the tissue? And will hot glue be light enough?
You are the right track in trying to lighten up the balsa. You can also reduce the width of the tail piece frame (on the inside) as well as the trailing edges of the wing. It would also help to replace the wood in the tail and rear fuselage with contest balsa. Any hard and heavy balsa pieces can also be replaced with contest balsa. You don't need to dope the tissue. It can be applied using a UHU glue stick. Hot glue is much too heavy. Use small amounts of carpenter glue.
You can get rubber at hobby shops that have freeflight supplies. Here are some: Peck Polymers, Shorty's Basement, Great Hobbies. If you do a google search of "Sig Tan sport rubber" you can probably find some more stores.
There are a few tricks to get it to fly like this. First is to keep it lignt. I trimmed away alot of excess wood, especially in the tail. I also replaced some heavy wood with contest balsa. For the prop, I used a larger (7") Peck Polymer prop, which is more efficient and turns slower. I also used Tan Super Sport rubber (you can get this from Peck-Polymers) that was lubricated with Armor All (car vinyl cleaner). I stretched the rubber as I wound it and put in about 800 turns.
Wow...that's awesome! I'm currently building the DHC-1 Chipmunk myself and I am amazed at how well you have yours trimmed for flight. How did you get the rubber band motor to keep going that long? Did you modify the prop bearing so the propeller can't turn quite so fast, thus conserving the energy in the rubber band? What's your secret? Great job!
great! just a little bit close up forlanding would looked even better!! I´ve made some chipmunks in penaut sizebut foam fiselage to simulate alluminium, stick and tisue I used just for wings, you can see thismodel in one of my visds, congrats again!
Beautiful flight! Did you change the fuselage and wing construction? How did you finish it? Non-tauting dope? Thanks

Haven't heard of rubber thread. For rubber power, I don't think you can get much better than FAI Tan II rubber with a silicon based lubricant.

have you heard of the rubber thread... my instructions says this works better for the model
