    Greetings Bearhawkers! Just a quick check-in to say everything is going well with BH5 biuld. The biuld is getting a little western now! Been some crazy weather around some parts. Hope you all are doing well. Cheers

      That doesn't look like a Lycoming!
      All joking aside, the auto conversions intrigue me. Did you go with an Autopsru or Robinson V8 drive? The installed weight I have seen for the LS3 is a roughly 100-150lb more than the 0-540 but I am wondering if it would affect the CG in a good way. I have read several reports of the 4-place running out of CG well before running out of gross weight and having more weight on the nose would help with that. Out of curiosity, have you run the numbers on the BH5 yet?
      I have thought a 300-320HP turbo-normalized V6 may hit the sweet spot between power and installed weight but there really is not much on the market that fits in the category. I will likely have plenty of time to think about it while building and perhaps that niche will get filled in the meantime.

      Keep up the posts! I have really appreciated the information you have shared!

        Nev, I have never came across any information on the B wings c/g. Your flight testing information is greatly appreciated.
        I am using a 10.5 aft leading-edge as aerodynamic center of lift in my calculations. Moving away from the recommended engine installation is a major deal. I simply would not suggest it to anyone who is not certain of their understanding & ability to be safe & successful.

        Nev, I really like you. In your videos it is easy to tell that you are a seasoned professional who imho is qualified to instruct.
        You may find it interesting to know the BH5 fuselage is 15" longer then the BH4. Firewall to tail post is 204" in the BH5 design. As well the prototype is flying around with counter weights in single pilot operations.
        Where some people see problems I see opportunities my friend!

        Bill, We definitely could use a different engine other than an LS3. 100% However! The LS3 is the single most modifiable engine because of all the amazing aftermarket support GMC promotes. As far as the posting goes you may noticed that my posting frequency has dropped off. I don't want to be responsible for any craziness. The facts of the situation is not everyone should be building their own airplane. Hopefully this doesn't apply to me! Lol

      I’m really hoping that the Corsair power ls3 conversion is a success and well proven when I start my build in about 5 years. I love the LS3 and am rooting for anyone that is brave enough to try the conversion!

            Happy new year Bearhawkers. Been rounding up all different firewall forward parts. For simplicity I ordered a 84" 4 blade electric inflight magnum IVO propeller. Control surfaces are well underway. Enjoying every minute of this project. I included a picture of the starter being weighed. It's lighter than a skyteck starter.

                Greetings, Sharing is caring. With everything we are all experiencing because of things going on in our communities. Our projects are a healthy distraction from it all! :-) There was talk about adding skin stiffeners to the B wing in response to the EAA photo of oil canning. This is how I applied the various solutions to my wings. Attached are photos of my stiffeners before skinning. 0.025 x 1.75 double staggered rows of 426AD3 rivets.

                  Greetings fellow aviators, I'm enjoying everyone's post on the various threads in our community. Thank you for taking the time. So today is my day to post. The engineering on the firewall forward is basically complete to the point it can be completed to in the concept of pen to paper. I have been satisfying my busy hands with assembly of the flaps. Today I'm fitting and drilling gussets to the 0.032 spar. Flaps lol more work then you would think, imho I took some pictures for anyone who could use the visual version of the story. Cheers
