The FlisKits Tiddlywink uses 1/16" balsa, but I would think that 1/32" would work as well.

Size blades in "Tiddlywink"
My 1st attempt I broke two of those blades. I was going to try 1/64th in plywood. Opinions?

Not sure if 1/32 would take the stress well. You could strengthen it, but if weight is the issue the strengthening would defeat that purpose.
1/64" ply, seems to me, would just be too darned flexible... jmho There are others here with far more experience in 1/8A HD, that's for sure!

1/8 A HD Blades
Hi Scott & Jim, appreciate feedback, So far, 1st flight with "tiddlywink" went well, except broke to of helo blades, so they r fragile! Thats why I was thinking of "ply." Another one of club members suggested 1/32 balsa, covered in "rice paper." I think the trick is going to be to try different blades and adjust for weight with what works.
Past Saturday met a little girl @ NAR Mid-Atlantic Open, in Mt Olive, NJ. She is going for records @ Naram this year in B division. Got an impressive flt of 37 seconds. So it is possible. My only record was 4 launches and 3 crashes in dual eggloft and streamer, with lots of "scrambled eggs." However, "Spaceman Spiff" performed flawslessly! Thanks again Jim for chute. U r welcome to use any of photos , if u wish. Glenn |

Like Jim I believe 1/64" Ply would just be way to flexible.
If your airfoiling the rotors starting with 1/16" balsa isn't a bad thickness. by the time you've tapered the trailing edge your average thickness well be around 1/32" anyway. On Most of the 1/8A HD models I've been flying of late the entire empty model tips at scales right around the 4gram mark, Both my own design Wonderwhirls and Jim's Tiddlewinks.

I would go with plastic when getting that thin. I use the Wal-Mart front license plates for a lot of stuff. You get a good size piece of plastic for $2...

Play it safe and go for 1x10 blades, probably out of 3/32" balsa so they're nice and stiff. Sure, you'll only get about 50 feet of boost, but great rotation on the way down .
