REFLECTOR: Ailerons and the dash five - Watch out!

Hi,

I am building the SEFG, so this is not an issue to me, but if you check the
August Velocity news:
 http://www.velocityaircraft.com/Velocity%20Online/VelocityonlineAugust.html

You will find the details of the -5 Aileron bell-cranks there.

Steve.

Terry-

  Don't feel too bad.  John and I had our wings on the fuselage and
completely rigged and back off before we discovered that the ailerons rigged
backwards.  We had to re-install the wings and re-drill the aileron torque
tubes.  Scott Swing told us (after we notified him) that he was going to
have the manual updated and would send out a KPC notice.  I have been double
checking that he did that yet, obviously not.  Sorry you got trapped by the
same thing, glad not as far as us.

Dear all,

This note is only for those building an XL dash five.  

Since flight controls are a major component, I think it is worth reporting
to everyone immediately.  

For the rest of you so you can follow along, in the dash five model the keel
drops in height about 8 inches just aft of the front seats so as to
accommodate that back bench seating arrangement.  The keel assembly
instructions for the regular XL are in Chapter 6.  We -5 owners have those
pages and we also have a set of Chapter 6A pages that are specific to the
dash five.  

Look at the figure 6-12 on the regular XL manual, then look at figure
6a-6 in the dash five pages.  You can see that the torque-tube-to-bellcrank
positioning is reversed 180 degrees.  The reason is the aileron torque tube
in the keel of the -5 sits just above
the floor.     

Now go to Chapter 10 on control systems and you will find no dash-five
pages.  If you follow those Chapter 10 instructions as written your roll
controls surfaces will be rigged in reverse of what you want.  Further the
suggested fire wall drill points for the aileron control cable is off, and
the cable supplied in the kit is too short.

I am guessing Scott B, who did know of this when we called down there, is
working on a revision. I am working on cabo'ing in a needless hole drilled
into my spar web and fire wall, and somewhat upset at this discovery to say
the least. 

Thanks,
Terry

An inexpensive electric heater that is shaped about like a shoe box.
Really, just a very big hair dryer only the fan is larger and turns slower.
You can find them at Wal-Mart for about $20.

Thanks everyone.  What is a milk box heater?

I heat my plane when the temps fall below a 20-30f range.

I use two cheapo electric milk box heaters. One hangs on the prop and blows
hot air onto the engine from the cowl exhaust port. I cover the cowl with a
insulated blanket to help keep the heat in. The other goes in the cabin. I
think its just as important to heat the gyros, switches and levers, I also
like to be warm when I taxi and take off. My wife really likes it. I heat
the inside up to 85-90 degrees. The engine usually shows about 60 degrees if
the outside is down to 0.

two $20 heaters and an old blanket is a cheap way to go and works like a

charm.
