The electric = air-condition mounted on the rear bulkhead has a condensation drain that = goes overboard through a =BC=94 hose. Is this usually an issue? Does = this need a control valve or should is drain to an internal = tank?
 
When testing the = cabin pressure control valve on the ground but adjusting the panel = controller back and forth, the motor and gears move extremely slow. Is = this normal?
 
On the ES-P, are rubber boot necessary on the elevator = push rod that goes through the bushing in the rear bulkhead and the = aileron control rod from the stick that goes through the bushing into = the sealed box?
 
Any suggestions on where to put the 6 PSI pressure pop off = valve? The is very little room on the pressure control valve box under = the left rear seat.
 
Is there a good smoke source for finding leaks when hooked = up to the shop vac?
 
 
Thank = you,
