Yesterday while flying the Cherokee Six I was doing some pretty spirited climbs to altitude seeing as though I was solo, light on fuel and had 300 hosses saying "GIDDYUP!"
I saw 1,200+ fpm quite regularly and did feel slight discomfort in my ear canals. I always chew gum and yawn to equalize. I am used to this because I SCUBA dive as well.
I was wondering how well I will do with a 210 horsepower RV climbing out at better than 2,200 fpm?
You guys with flying RV's... how do you feel with rapid climbs? Any discomfort at all?

my 8 climbs at greater than 2,000 fpm. My airport is at 1,953 and it takes me about 3.5 minutes or so after lift off to hit 10,000. I don't really notice it but then I have never had trouble equalizing my inner ears. But I think your method will work just fine.

Thanks Dan!
I may be coming down with the cold is probably all, I suppose. That would explain the discomfort.
You got 180 Fuel Injected HP in yours, if I remember correctly?

Yup, Aero Sport Power IO360 180 hp with WW200RV constant speed prop. Bart claims 195 HP on the Dyno. And It sure performs like it!

John,
I think you answered your own question there.. I little congestion in the sinuses or a cold will cause a good deal of discomfort at times.
My RV-4 can climb out around 1,900 fpm if I want it to, and I never really notice any problems even without the chewing gum.
BUT, if I have a cold, or a sinus stuffiness, then it can be painfull to descend quickly.
I try to keep that in mind if I take someone for a ride who may have a slight cold or is a non-flyer.
