I wanted to share a problem I had that could be very serious. Granted most of you would not be as stupid as I was. I had just finished an engine run after fine tuning the fuel servo mixture. My mind was distracted as I analyzed the data. I shut down and was going to exit the plane. I normally...

Received the kit today. Thanks to my neighbors who helped unload. Ready to get started. First impressions: What an amazing packing job! Those wing crates are hell for stout and there is approximately zero chance they are moving in route. Things were for the most part were labelled very...

I found this old spreadsheet that I had been searching for that was developed for Sport Aviation Magazine in 2003 by Neal Willford. It calculates oil cooler sizing, inlet and out cowl areas required based on user inputs including HP, TAS, Altitude, baffle vs plenum, inlet/outlet air ratio...

Wanted to share how I wasted time chasing a rabbit on my EFII fuel pump. Im sure many of you in your search for fuel boost pumps discovered amongst the available options, the EFII has the lowest pressure drop when its not running. I certainly did and that along with fact that it was working...

Do we have enough data out there on the the prototype and first kit built angle valve model 5’s to draw conclusions on the correct oil cooler size? What little data I have seen shows really good CHT’s but the two data points I saw showed 210 degree oil with 327 CHT and 217 degree oil with...

My name is Dennis Ramsey. I live in South Carolina. I have built a Lancair IV which I now have over 1200 hrs on and a Just Highlander which I had about 330 hrs on when I sold it to buy a bearhawk kit….not realizing the time delay in receiving the bearhawk kit…ooops. But the good news is I...
