REFLECTOR: Questions for those already flying

[Alex]

I flew a long EZ for some time, used the speed brake twice-  and really just
to see how it affected landing- S-turns seemed to do the same thing, and
they certainly are more fun-  but then again I don't use the flaps on the
spam cans much either..... maybe I just like to land that way- I did hear
that folks say that the speed brake keeps the rocks out of the prop from the
nose wheel, so that could be an advantage- especially if you have the
fragile MT mounted back there.......

XLRG, no speed brake.  Advantage of no speed brake is simplicity, no
inadvertant deployment or failure to retract on TO or go-around.  Dropping
the gear will get rid of altitude promptly if power is chopped.  Besides,
using the speed brake to dissipate altitude and speed is an energy waste.
Preplanning can make good use of both to get there faster while using less
energy.  It's actually a pretty rare instance that ATC slam-dunks a person
such that the brake is needed.  Even then, "unable" works equally as well.
Speed brakes seem to be very much a personal preference.  The best value
I've heard of for the speed brake is it seems to cushion the nose area such
that at touch down, the nose doesn't "plop" onto the runway as sharply.

I have an RG, 

I have a speed brake, use it most landings.

I accidentally replied  about cabin heating to another posting on "oil
cooler issues",  I'll repeat it again.

I had a cold airplane in the winter.  Mainly due to two reasons. Inadequate
sealing of the nose gear  mechanism and using the nose oil cooler as the
cabin heater.  When its -20 outside, the nose oil cooler as a cabin heater
is trying to raise the temperature at least 100 degrees, 120/140 would be
better if the plane is cold to start with. It just can't do it. 

I have a internal oil heated cabin heater now that will recirculate the
cabin air which should be able to roast us alive.  Its not flown yet so
can't say if y design works well or not.

Hi,
 
A couple questions for those already flying...
 
If you didn't install a speedbrake, if you were to do it again would you
install it? 
 
If you did install a speedbrake, are you glad you did? Do you use it often?
 
I have heard that with RG's it is hard to heat the cabin at altitude and/or
winter. If you could do
it again, would you still cut the NACA for the oil cooler? I have heard
people using two coolers,
one near the engine to be used during the summer,  and another in the nose
that
is used as a heater during the winter. Any thoughts? 
 
Thanks,
