Hi,

Just completing this ARF Corsair (I guess you could call it semi
scale). Anyone have any experience with this model? It's a .46 powered
approx 1/8 scale, wing span 1.5 m.

The first question I have is concerning the control throws, they
specify on hi rate:

Elevator 13mm up 16mm down
Rudder 44mm left and right
Ailerons 7mm up 10mm down?

I heard that it is better to have more up Aileron than down so which
is correct?

There is no right or down thrust built in to the model (as far as I
can see) or specified, Should I include any?

C of G is specified as 3 1/2 inches back from leading edge, would it
be more stable a little nose heavy?

Any other tips?

I'm fairly new to RC flying, a few hours flight time with a trainer
and an hour or two with various SPADS... How difficult do you think
this Corsair will be to handle ?

Thanks in advance,
Trevor.

Hi;
No expert here, but I'll take a shot...

Intuitively, I think it would require more force to lift a wing than to drop
one, so I would agree with the 7 up, 10 down spec.

If it's not specified, I wouldn't put any in. If the plane tends to pitch
to the left, you might put in some right thrust later. Maybe the bent wings
help it track straighter? On a low-wing model, I don't think you want any
down-thrust, but rather up-thrust, if anything.


Yes, though, I would make the first flights with the CG as close to the
specified location as possible, but moving the CG forward is generally safer
than moving it back.


Were the SPAD's some type of low-wing variety? What I did, in preparation
for flying my GeeBee the first time, was invest in a low-wing foam warbird,
with ailerons. I think it helped. High-wing models with dihedral tend to
self-correct; low-wing models pretty much stay in the bank where you put
them.

Taking off the first few times was pretty exciting! Ease the throttle on
(don't go full-blast all at once) and wait for the plane's speed to kind of
catch up with the prop as you advance the throttle. Use gentle rudder
inputs to correct, and I found it very helpful (essential, really) to keep
the elevator close to full-up to keep the tailwheel on the ground and
tracking straight, until I was pretty close to takeoff speed. Once it was
in the air, it was a blast! Dan.
