Bearhawk Patrol N357MB

[joehmason]

My father, Mike, and I received our Bearhawk Patrol QB kit in September 2018. I was confident it would be airborne in 18-24 months. After a humbling four years and four months, on January 16^th, 2023, N357MB took flight with Dad at the controls. The first flight was successfully uneventful, just as we hoped it would be. I took the second flight on January 20^th. It was also uneventful, but after two hours in the sky there was a laundry list of items to fix and troubleshoot. We have slowly been working out all of these issues and we are very close to having everything addressed.

Being focused on engine break-in we have not done much flight testing (stalls, slow flight, maneuvers, etc.) For the little bit that we have done, the performance has met or exceeded all expectations. We have experienced 200’ take-offs, 1800 FPM climbs, 150+ true air speeds, and sub 40mph stalls. With our field elevation at 4150’ MSL, these numbers are better than we could hope for. The Hobbs reads 26.3 hours as of today and we are waiting on better weather to finish our testing.

We are thankful for this forum and everyone in it who betters the Bearhawk community. Both my dad and I have been lurkers, only contributing occasionally, but we have learned from people who post regularly.

Congratulations! Nice looking aircraft. And don't feel bad about the four years...I've been at it WAY longer and have yet to fly.

[Sir Newton]

Impressive numbers on 200hp

Great looking airplane, makes me pine for my patrol kit even more, what issues have you had? anything we need to be on the lookout for? please contribute more.

Congratulations! Awesome job.

She looks great. A professional build. I have thought about polished wings for a bit of weight savings...and looks.

[joehmason]

Thank you everyone for the kind words.

We like the polished wings a lot. Dad has owned a polished Luscombe for 50 years, and this seemed to fit right in.

RickG - Regarding what we experienced during the test flights, I am working on a more detailed write up of our experiences, but here is a short list:

1. Tailwheel chain clips bending open and coming loose during taxi
2. Fuel cap venting
3. Small oil leak at front of engine
4. Airspeed indicator malfunction
5. Dynon always showing a headwind
6. Tailwheel shimmy
7. Rudder trim
8. Heavy wing
9. Stalls not breaking straight forward
10. Static port issues

None of these issues were detrimental to the safety of our flights. They are very typical items to find on test flights. We have addressed most of them, but are still dealing with a few of them. I will post the detailed write up at a later date. My hope is that that other builders can learn from our experiences.

[*]Dynon always showing a headwind

Sometimes, it seems that is reality...

[JimParker256]

I know exactly what you mean about "always a headwind..." I took a trip to the Salt Lake City area in Utah (from Dallas) to pick up an airplane a few years ago. On the flight west, we fought 15-20 knot headwinds the whole way. We were there for two days (doing some transition training before the cross-country home), then flew home. Man, I was looking forward to those 15-20 knot tailwinds... Alas - what I got was 35-45 knot headwinds the entire way home - which REALLY sucks when you're flying an airplane with a cruise speed of 105 mph... Needless to say, the flight home took a while!
