RADIAN PRO FLAP MODS

After the successful flights on Monday, Ray was concerned that the flap travel was too low to actually kill of the lift from the central portion of the wing.  As a result we actually increased the lift and contributed to the difficulty in landing.

So.  Today I removed the covers from the flap servos, shortened the pushrods, and shifted to the outer hole on the servo and the second from innermost hole in the control horn.

With some radio mods, the flaps now go to 90 deg. when fully deployed.  In the first part of the video it displays the travel as it came from the factory with max travel.  The second half shows the new travel.

Next flight will have to see the impact of the changes.

First flying day for 2012

Monday was spectacular.  This was my first flying outing for this year.  Went out with Ray Meyer.  Made several successful flights.  2 with RADIAN PRO, 2 with the ParkZone Corsair and a maiden flight with the Eflite Mini Ultra Stick. 

I got some lift for awhile with the Radian.  This was still some fo the first dozen flights for this bird.  We discovered that the flaps don't seem to go down far enough to kill off lift and as a result it slowed some, but didn't want to come down.

The wings are in the shop.  I hope to rework the pushrods and make the flaps go as close to 90 deg down as possible.  We'll see.
