KR> Ercoup flying

I owned my ercoupe for quite a number of years and put hundreds of hours in it. The limited elevator was but apart of it. The controls were another very big part of it. Also there were no springs between them. There was a mixing bellcrank under the baggage bag. It was all hard connected with rod

I'm a propane tech here on my island, and we use soapy water in a spray bottle to detect any gas leaks in the plumbing. Low pressures are a few inches of water here, so this is a very sensitive leak-detector and localizer. Peter You could alternatively pressurize the tank with nitrogen and t

Your main challenge on a KR is stall speed. If you don't build it very light, I do not think you will be able to meet this requirement. Remember this is "clean" stall, no flaps. Dan Heath > On Jan 31, 2014, at 11:35 AM, Dj Merrill wrote: > >> On 01/31/2014 02:21 AM, Mike T wrote: >> These tw

I've never flown one, but the 'coupe had spring-mediated control linkage between the rudder and ailerons which provided automatic control coordination. This worked very well to prevent the cross-control stall problem, but made crabbing into a cross wind and slipping more difficult...not impossib

There are pros and cons to both flying high and low. The bottom line is I have had several engine failures at lower altitudes and have not had bad outcomes with any of them. It is truly a matter of skill and preference as I enjoy seeing the scenery below me as well as the clouds once in awhile when

Gents Use a balloon attached to one of the inlets/outlets of you tank. Temporarily seal the other inlets/outlets. Use one of other inlets/outlets to blow up the balloon so that it is about half inflated (on average 5 to 6inches diameter). Leave it sit for a couple of days. As the tempera

Roger, We'll congrats! Even if I'm late on posting this it is good to see another KR up in the air. I had pretty good success with the Revflow in my Revmaster 2100D from the beginning. Just had to do a few adjustments on the needle to get it from being too rich. Not sure why some folks have n

I can't argue with the logic of building the wings separately and then attaching to the fuselage. 707s were done this way and they may still be building that way. On Jan 31, 2014 1:22 AM, "Mike T" wrote: > I'm still trying to decide whether to build a KR-2 or a Thatcher CX4, a > recent single-se
