Default RE: SkyMaster MB339 Build Thread

25mm flap is indeed a more lift producing as a drag increasing setting.

Combine the enlarged flapsetting with a few mm UP ailerons (crow brake). Don't overdo the aileron UP value as it greatly diminishes roll control. Find by testflying the elevator correction for this setting so You don't need to correct on final Yrself.

Activate the belly speedbrake, not too much of a work, the extra speedbrake panel is normally a part of the kit, maybe the previous owner still has it lying around. Or it might be ordered with Skymaster.

Indeed, testfly slower approach speeds, a system like the Eagle Tree which gives airspeed values can be of great help learning to fly slower. GPS speeds can only be used at wind-less days, as GPS gives groundspeed that varies with windspeed. As soon as You have been accustomed to the angle of the fuselage on final that gives a safe final speed, You can forget about telemetry.

Good Luck,
