When the glass is half full instead of half empty:
From: Allard van Wallene
A remark from a known F1C flyer:
Flappers and folders have less drag than conventional C ships. At 5 seconds the speed of a flapper/folder is much higher than that of a conventional ship. The acceleration and speed in the first 2 seconds is almost identical.
Cutting away the last 1 second from a faster model will cut away more altitude.
So the penalty for a flapper/folder going from 5 to 4 seconds is much higher than the altitude loss for a conventional ship.
Conclusion: the new rule will result in a reduced altitude difference between flapper/folders and conventional F1C’s. Wasn’t this what most F1C flyers wanted or am I missing something?

Allard
F1C Test - in reply to Ross
All, I have flown a Babenko folder on 4 seconds, it doesn't get as high. Surprize! Artem's RDT which I use will not work until the model is in glide mode. A separate or new system is required to shut off engine at will. To do so say at 3 seconds for a model off pattern creates an unguided missile due to the momentum. This does not solve anything.
Best,
Ed Carroll

Yes. I've just picked up the re-run.
I wasn't sure of what to do or how to handle. Urlan thanks for making comment.
On that sad front we lost Mick Howick only just a week or so back.

See the note below from Alan Abriss and me regarding the Hatschek
International Challenge. I am informed that Alan will be performing CD

Jama Danier from Canada is likely to attend and there is a good chance we
will have back with us a familiar W&O flyer Marion Whitney. I hope to see
many of you there. Andrew

F1B Winders for sale

Hi Roger.
I have 2 F1B winders that I would like to sell. One is an Andriukov, well
used, but still in very good shape. The other is from Yuri Blazhevych, and
is like new. Both have good working torque meters, and a 5 to 1 winding
ratio. Neither have a counter. I would like $250 each. I can be contacted
at This email address is being protected from spambots. You need JavaScript enabled to view it.. Thanks, George Batiuk
