I should have probably titled this post Sacrilege, as it is likely the response some of you might have. But I felt important to document what I did and why I did it.
In my view, Bearhawks are the perfect plane for my mission. Its design will get in and out of incredible short strips even with heavy loads, but whats unusual is that it is also fast and relatively efficient in the STOL world.
I built my 5 to be a family camper. I have no intentions of doing STOL competitions nor push my luck landing on sandbars. I had a great STOL plane in a JUST Highlander before the Bearhawk but it was slow and only had two seats. My daughters decided to surprise me in their late 30’s with three grandchildren. I wanted to take them airplane camping and so the JUST was sold and Bearhawk 5 kit bought. From day one I have not yielded to my big tire preaching airpark neighbors(none of which have big tires) because while I like a challenge, I wont take risks with the grandkids on board. Small tires provides a constraint for my male hormones that naturally would lead me to gross episodes of stupidity. I love watching Steve Henry land his Just on a 60 ft mountain top or his infamous dead stick takeoff from a mountain top. I will live vicariously through him.
So thats why small tires (7’s) and I also want to do long distant camping runs and want to take my wife to Alaska without having to stop in Canada. The Bearhawks speed and range are therefore important. I was Bearhawk camping on a short grass strip with a C180 driver who started talking wheel pant benefits. My big tire preaching neighbor witnessed it and said oh brother, I see a foam order coming. I did not want to disappoint him so I bought some foam and took pictures of RV wheel pants and was off forming my own carbon fiber wheel pants. After the requisite endless sanding and filling (Photos available upon request), I was done and ready for flight testing.
Its soooo difficult to get apples to apples data comparisons but what I can say is the fastest my Bearhawk got at 75% in initial flight testing was 168 MPH true at a fuel burn of 16.4GPH. With the wheel pants I was able to get that same speed LOP at 13.3 Gph. When I lay the new test flights over past flight data I see 7-10 MPH increase but I would have to say the average is closer to 8. When I did the math to take new flights to 75% power the result came back at 7.5 MPH increase so seems close to the same answer. I did not optimize efficiency at all but did test as high as 10500 which gave me 158MPH at 11.8 GPH. I also did descend at 800FPM which produced 185MPH true so I could see if anything excited the wheel pants….but they just seemed pretty bored with the whole thing.
It takes about 5 minutes to remove the wheel pants and through them in the luggage if I feel they might get damaged in a particular intended landing spot,
So basically I got almost a 20% range improvement with a little sweat equity and maybe $500 in materials.Side note. You will see that my oil temp is not a fan of 2500 rpm but its well within Lycoming spec. CHT’s are fine.
