REFLECTOR: Questions for those already flying

[Chuck Jensen]

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,
