Probably could use a 6cl if flying at gross weight out of the Backcountry. Unless you have plenty of room, and/or very low density altitude like you find in Alaska most of the year, a four place 180hp is not going to cut it for true STOL over obstacles.
@@josesbox9555 Lycoming Thunderbolt has a 215 HP version now ... Install that and a 4 into one equal length exhaust header which would bump it to about 222 HP .. use Oratex pre colored covering ( big weight saving ) earth x lithium battery ( 10 lb saving ) , light weight whirlwind ground adjustable prop and with you flying alone you would have a lightweight back country rocket ..... that could seat 4 also
Great! Not really a fair comparrison though, obviously the patrol will have a better power to weight ratio. I would like to see it compared to the 4 place witht the O540.
Thanks for the great video thanks for telling us some honest weights on those planes. These are some of the only videos that actually have honest numbers. Comparing the numbers to my Bushmaster with the same engine.
Two amazing airplanes. Just a question of your mission profile. Thanks for the side-by-side, and huge thanks to Bob Barrows for bringing these fantastic designs to market.
Great comparison. Two different seating configurations with the same engine, same day, simultaneous conditions. They are remarkably similar when solo. But of course the four seater is going to struggle off that gravel bar with a full load, probably needs an O-540 for gross weight true Backcountry STOL operations? Otherwise it probably accelerates like a 172/180hp with four adults? i.e. = Meh.
Thanks for the comparison. Just wondering why the all out airspeed is so slow compared to the advertised 160mph from Bearhawk with that engine. Can't be just the 26" bushwheels? I bought the plans years ago, and love Bobs concept and talents. My S-21 pales by comparison, although slightly faster at 133mph TAS.
Are you based in Seldovia now? I spent a lot of time there years ago. one of my favorite places in Alaska. Always loved flying around there. I enjoy your vids.
Great comparisons. I have a Bearhawk 4-place. Do you know if I can purchase the flap handle modification or contact the person who fabricated it? It is really difficult to operate as is. Thanks.
wery interesting all things considered the jury returns for the bearhawk 4 , he can sleep in his, if the bears bother you too much patrol guy having to sleep outside i am sure he would let bunk for the night, is that a B bearhawk ( Note biased I have plans for the B version 4 place) must watch the video again, same engine different props whilst not an exhaustive scientific video still very interesting you would think that the patrol would totally trash the 4 place however yes but only marginally, then you stare at all the real estate Lebensraum you have with the 4 place. :)
Hi, thanks for all the video’s regarding Bearhawk aircraft. I have a question, will the 26 Goodyear tyres you use work on the four place. The four place have a 2700 lbs takeoff weight. I will not go to all those serious places where you need 31’s though I would not mind 29 heavy thread ABW. Too much money for cool. My other option is the 900x6x10 ply they use on the DC3 for the tailwheel. Your advice will be much appreciated
Take the tires off and slide them in...you'll see them stuffed in back on most of our vids. Takes about 60 seconds to load them up once both tires are off.
The glide at idle is not a comparison criteria due to drastic differences in constant speed props ... In other words it is not valid other than showing what a great brake the prop is ....
I think your best glide should be reduced 5-10 mph. Something not adding up on that comparison. A heavier airplane with the same wing should not out glide yours….
The Bearhawk is a flying brick sh#@house compared to other aircraft. It's so robust and yet manages to suffer no apparent performance penalty as a result. It's impressive.
Cant build a Maule nor buy a certified Bearhawk .. and by clone you mean the angle valve injected 540 bearhawk blowing the Maule away in performance and looking completely different I suppose clone it is
Jamal Ahmed Depending on your english reading ability, and if you are planning to get a pilots licence in the USA. I can point you to all of the training materials you will ever need to pass the FAA written exam. All the study documents required for that test are available on the FAA website for free. Airplane flying handbook: www.faa.gov/regulations_policies/handbooks_manuals/aviation/airplane_handbook/media/airplane_flying_handbook.pdf And the Airman Certification Standards that you will have to train for can be found here: www.faa.gov/training_testing/testing/acs/media/private_airplane_acs_change_1.pdf In addition to the FAR/AIM (Regulations manual). You will need to study parts 61 and part 91. www.faraim.org/faa/far/index.html Plus read the entire AIM (aronoutical information Manual) at least three times. www.faraim.org/faa/aim/index.html It includes all the weather minimums. (Plus a few hidden gems of info that if you read them it might help you get a 100% score on the written exam!). Like how close is a near-miss considered for general aviation = 50 feet. That's the one question I got wrong on the entire test... said 500' instead, wrong. Lol. You can find FAR/AIM for free line at many different places like those links above or at www.gleim.com/aviation/faraim/ The only book ever written that tells you exactly how to actually fly the airplane, and not just a bunch of rules and regulations is this one. It's a MUST READ. (though it's written in old-fashioned English it's hard to read even for a native English). Nobody has written a better book on flying then STICK and RUDDER. books.google.com/books/about/Stick_and_Rudder_an_Explanation_of_the_A.html?id=Km3WAAAAMAAJ Other great books once you have mastered the basics, and have maybe 20 hours of flying experience or already have your private or sport pilots license I recommend: Aerodynamic for naval aviators is the masters thesis on piloting, aerodynamics, energy. www.faa.gov/regulations_policies/handbooks_manuals/aviation/media/00-80T-80.pdf&sa=U&ved=2ahUKEwiZ4cKYvMnrAhUBWqwKHQZCDzsQFjAAegQIBxAB&usg=AOvVaw223QV0b_t3qnxyaT5Yq6qp And a little know gem full of piloting wisdom and philosophy: The Thinking Pilots Flight Manual, Vol 1&2. books.google.com/books?id=QS-atgAACAAJ&source=gbs_book_other_versions This is the ENTIRE list of study material and extracurricular books you will EVER need as a sport or private pilot. And most professional pilots have not read all of these books, which is a shame. They really are the best. And I've read over 100+ aviation and flying books.
Maule has been very aggressive with its pricing. At the airplanes introduction, a VFR version went for $79,995. Today, and average-equipped MXT-7-180 with a constant-speed prop and average equipment goes for a little over $145,000. get building do your own thing non certified however no fare paying passengers or commercial work but save pots of cash the EAA way. heard a brand new cessna 172 is 400k these days
Not really fair comparing a 4 place with single pilot vs a 2 place with single pilot. Of course the 4 place will have better performance and itvwill stall slower since it has a wing sized to carry much more. . A true comparison would be both airplanes at max takeoff weight. This comparison is quite meaningless.
i not understand why some waste lot money bearhawk kit 72K$ plus engine, because lot cheapen can buy used cessna 170 and save 50% cheapen money cessna not need do anythink but kit plane go lot hours build all , go lot more money buy kit plane and work hours build it, but used cessna not need more than go fly.
