Just how much flap reflex are we supposed to have in our planes? I'm an owner, and didn't build it, so I have no way of finding out other than asking the experts out here. When my flaps are reflexed fully, I have about one inch between the fairing on the fuselage to the flap; in other words, the flaps rises above the fairing by that much on the inboard side.

 

Oh... And Greyhawk... I saw your speed for the EAA race - nice! We'd have fun racing together... My best Reno lap speed was 237 mph on a measly, stock O-360... Not even an IO!

Scotty,

 

First, let me point out that the EAA Race posted data about my engine is Kraaaap!  I fly behind a slightly adjusted IO 320. Period. 

 

Second, If your fuselage is a actual 320/360 device, the faired in position is -7 degrees of reflex.  Much more or less will slow you down per reported experimentation by the cross country guys (Hi Speed Larry, Speed Demon, Doughboy and Grayhawk).  Note:  Scotty, I will add you to our interchange list where it is up to you to separate the taunts and lies from truths and bigger lies.  You have got to try a long distance run (rather than constantly in a turn) to allow yourself time to consider the benefit/drag of certain "mods."

 

So.....

 

1. You are losing speed because of drag induced by the poor flap/body interface.

 

2. You have caused the plane to pitch excessively up because of the higher than designed flap position.

 

3. There is increased drag because instead of unloading the tail it is actively fighting nose up pitch at max power.

 

4. Egads man!  There is hidden power in an injected engine.  I/O engines have a better chance at balancing the HP delivered by each cylinder.

 

Perhaps we could meet at some secret undisclosed location about halfway between us to discuss, um... things.
