It depends on how much you end up weighing. Lee Robbins has been fling one for over 20 years now on a type 4.

Alright, thanks. It's hard to tell what the consensus does as I think I've read about some builders adding 4" or so to the stabilizer, and reducing elevator area to reduce pitch sensitivity (even on the -2S). > > - How well does the tri-gear KR-2S handle grass > > strips?

I had asked before KR-netters opinion about to use them on KR, but it seems no body know about. Generally the Quickie and Dragonfly owners who have installed them reporting not only fixing bugs/rain contamination fixing but as well lowering the stall speed.

I've seen some paint damage on spam cans out here due to flying in severe rain. I haven't flown my KR out here, but haven't heard from local EAA ers not to fly in the rain generally. Their was a canard aircraft which had some rain issues and I think I heard some similar comments from a Long-EZ pilot who had some canard fix. I'm open to hearing from netters on this, but haven't been "warned" off of flying when the wing gets wet. I think this is one of those "laminar flow" type concerns and at the moment, I don't even recall if the KR airflow RAF-46 (I think) was a laminar flow airfoil. It's older so I would bet it is not laminar flow... but I'm a hose head, and often wrong. -- Ross -> each time it drizzles i don't fly i cant find any information on the -> effects > of lite rain other then higher stick pressers with the Kr. it seams that > most wood propped airplanes don't fly anyway do to damage with or > without > urethane edge is what i understand. i just like to know if IM caught in a shower > will it do damage to the aircraft i always wipe it down if it gets wet or > washing i also avoid the hinge points (controls) mac. > > > > > > > > > n1055a flying > flymaca711689@aol.com _______________________________________________ > see KRnet list details at http://www.krnet.org/instructions.html -- ___________________________________________________ Check out the latest SMS services @ http://www.operamail.com, which allows you to send SMS through your mailbox.
