currently I'm building the greatplanes extra 300S .40
I'm having troubles understanding the manual when it comes down to
measurements. (not used working with "inches"....
1", 5",...3/4"...etc is not a problem. (I have a conversion chart)

Which off-the-shelf electronic pressure sensor component (part number) would
be used to measure altitude of a baloon starting its journey from sea level
(0 meter) to 15000 feet (4,572 meter) ?
(I assume the pressure sensor outputs analog signal and which will be

Hello!  I am a modeler of 40+ years mostly CL but I dabble in sport RC
and FF.  Most of my planes are my own designs because I dont like
flying the same ARF that everyone else owns.  Usually they have foam
wings that I cut myself.  If any of that is of interest to you drop me

I am struggling with a problem.  I have a Tower Hobbies .61 engine mounted
inverted in a Great Planes J3 Cub (12x7 prop) and I can't stop it from dying
in the air.  Damn thing runs on the ground without a problem. It will run

  I found a 40 size trainer kit the other day, buried in the closet,
and will probably build it this winter.  I'm looking for suggestions as
to what I might want to add to it, delete, etc.  I have an 8 channel
Futaba TX/RX, so there is room for more servos if needed, and I can

I'm restoring an old model plane given to me by my dad some thirty
years ago - maybe longer! Anyway the CA hinges were shot, and I just
cut through them along the hinge line. I was able to re-slot where the

does any body have all the views for a red white sunburst pattered Cub?? as

everybody know of the new line of ARF aircraft that we now offer. Some

I am setting up a Hyperion ESC for Li-Po and the default setting for the low
voltage cut-off is 2.8volts for use with a 3S pack.  I thought the usual Low
Volts limit was 1 volt per cell...i.e. a LVCO of 3volts.  I can't change the
settings of the Hyperion without their Emeter.

Some people have mentioned to me that this plane would help me practice
aerobatics.  I just dont have the time/energy to haul my stuff to my club's
field daily.  I really want to work on 4 point rolls  and rolling circles.
Do you think this plane, brushless powered might make a ...

I know I had a formula written down somewhere (probably in 8th grade
about 1953) to calculate how much castor to add to a given volume of
fuel, with a given amount of lube already in it, to raise it to another
level (%by volume).

I'm completing a Sukhoi 31 ARF and didn't like the dowel type pushrods
supplied for use with the rudder and elevator(they were too large and
rubbed inside the fuse) so I bought a set of Sullivan "Gold-n-rod" to
use.

 I just saw the  H9 p51 pts  and would like to know if anyone has
one?
they are supposed to be somekind of a trainer i'm curious..
 thanks.
