Got a little work done this week on both the Belyayev DB-LK plans and on the Martin P5M Mercator plans.

Looks like the Mercator will have a 72" wingspan with Power 15 motors or similar clones and twin 64mm ducted fan units on three cells, with each side sharing on 3 cell 3000-3300 battery. The fans will only get run a little during a typical flight.. Brakes will be active on the ESCs so that I can stop the props and do a fan powered flyby... Will have some mixing so that I can run the props and fans together with a switch on, or props alone for normal flying, or fans alone as well. Looks like a 7 channel model: with the three normal flight controls, throttle, electronic retracts, flaps and EDF units. Lots of servos: 6 in the wing for ailerons and flaps, two elevator servos, one rudder servo, three E-tracts and possibly two more servos to actuate the retractable inlet for the fan units, assuming I go that route instead of leaving it open all the time.
