AFAIK it was single-channel with 3 *cascaded* (Bonner Varicomp) escapements, as mentioned in the plan.UStik - 08/01/2017
Please find attached photos of my recently completed & flown Phil Kraft Bi Fli built from your OZ plan 823 [more pics 003-005]. When I first saw the Bi Fli in an old magazine found at our local hobby shop I was hooked on the design. Must have read over the article a dozen times. Quite some time later I found the plan on your site, downloaded, printed it off & started construction right away. I made a few changes to the construction of the nose area to suit modern motor mounts & fuel tanks. I also intended to use servos instead of three escapements! The engine used is an OS 15FP with 8-5 prop - which worked out well - not over powered but enough to allow takeoff's from our grass field. This model has a terrific flat stable glide. The fuselage is covered with silk span & dope, wings & tail with Solartex. After the colored dope was applied the entire model was then sprayed with automotive two part clear in order to fuel proof. This summer I will fly it with my 2.4Ghz converted Kraft Reeds transmitter for nostalgia sake (and a step up in technology from rubber driven escapements).

Notes
* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
Scaling
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
