I recently acquired a bunch of old school R/C stuff from an old builder and flyer. In the stuff I found 2-3 of these and I'm really not sure what they are or their function. Do you guys have any ideas?

Can you tell me what this is?

LM339N voltage comparitor
H9345 lists as a stepper motor control chip
Can't read the others but I would expect it to be something on the lines of a gear sequencer or an ESC for brushed motor. The number of plugs makes me think its a gear control, possibly the old Kraft electric retracts controller.
*****************
Found the old Kraft retracts... won't be that. This board is too large.FF gliders and rubber power since 1966, CL 1970-1990, RC since 1975.
current planes from 1/2 oz to 22 lbs
