Re: KRnet> CG. Issue or no issue

Colin writes: "Build them right and light and build in the correct empty C of G position and there are no issues with the plane at all. Only issues you want to dream up." Larry responds: "Builders and fliers on the net would be better served if you would use your knowledge and expertise to edu

Re: KRnet> CG. Issue or no issue

Larry writes: "The simplest way to determine correct empty CG location would be to use a bit of reverse engineering. Build the airplane complete to the firewall and then determine the desired location of the engine that will give you the most aft CG location when considering arm and weight of

Re: KRnet> Load testing of the KR2S and variants

In November 1977 the New Zealand Civil Aviation Division (as it was known then) published a set of hand-written notes by one of their engineers (Mr H O Ewart) describing the load testing required to clear NZ examples of the KR aircraft for flight in this country. Interestingly, Hugh Ewart's fig

Re: KRnet> Landing and full back stick times.

Whilst I am in no position to comment on KR-2 handling qualities, the 'test pilot' data collection nerd that I am can't help using Colin's information to quantify his short field landing in Iceland, given that the wind was 'calm' so that's a nuisance variable that can be ignored. Touching down

Re: KRnet> Fuel price

"Don't forget that, for all intents and purposes (even though it is a "continent") Australia and New Zealand are islands and don't have a 'native' source of petroleum. Almost all raw materials for manufactured goods are shipped in... kind of like Hawaii... Different economic issues all around.

Re: KRnet> Max Fuel tank Capacities.

Some points of clarification. High Altitude Upset Larry notes as a definition of 'airplane' upset: An airplane upset is an undesired airplane state characterized by unintentional divergences from parameters normally experienced during operations. An airplane upset may involve pitch and/or bank

KRnet> Request for KR-1 Stalling Data

Greetings KR Enthusiasts I am in the process of restoring New Zealand's only KR-1 which was completed - as per the plans - in the late seventies and has sat in storage for some 20-plus years since last flying. Of note is the fact that this aeroplane had no static system, and the static inlets

Re: KRnet> Request for KR-1 Stalling Data

"This won't help you, as my KR1 buffets at 62 mph.(53 kts). Haven't taken it into full stall yet. That was with retracts down. Plane is pretty much to plans, tho heavy (785 lbs) as flown. " Hi Kevin On the contrary - the data that you present is extremely useful indeed - thank you! It is u

Re: KRnet> Request for KR-1 Stalling Data

"Will the authorities not allow you to test you aircraft to determine if it meets the requirements. It seems absurd that they disqualify your KR based on information from a totally different airplane and even yours with a non-calibrated and questionable ASI system not even knowing the temp and
