Go for it! Nothing can beat a Bearhawk

Two questions if you don’t mind - How many hours do you think it’ll take start to finish for the bear hawk 5? 1000? How are you making the carbon fiber? Do you have a pressurized oven in your hanger lol?

@@ivanvujosevic289 I would say if you have built tube and fabric and are proficient with sheet metal, 1200 would be a minimum if you stick to the plans. I will probably have at least 2000 in this one. I use a combination of vacuum bagging and heaters when possible to make the carbon parts. I use west systems epoxy and heat is not necessarily required but Does help.

@@The-virg damn that’s a lot of time. I’ve been looking at this model 5, but really don’t want to work with fabric

@@ivanvujosevic289 honestly fabric is not that bad. It was probably one of my favorite parts but I have worked with it before. Building is all about learning new skills constantly. What I always tell people is if you are simply building to fly and have no desire to build it will be a long road. If you enjoy the building process or have specific purpose to build then build. otherwise just buy. We needed a specific plane for our mission agency, that is why I built but 2000+ hours in the shop is alot of time.

Greetings sir newton.

I have been debating pulling it off and duplicating it or pulling a mold. I'd hate to have to build another from scratch.

Dude, pull a mold, making that first part is the hard part. There are a lot of Bearhawk builders out there and the BH5 needs the CG help for sure. Once you have a mold then just make a second Part and narrow it to fit the BH4. Pull a mold off that and you're in business. I do recommend putting some foam core in the outer shell to damage isolate the inner and outer skins a bit.

Yeah you can do whatever you want when building. Several have but in large windows.

This could definitely be done on a 4 place but it would be much shorter and narrower. I did not make a cad drawing because I don’t have access to a cnc router to shape the foam mold. If you have access to a router that large it would make the process much easier.

Thank you Virgil. A longitudinal profile curve of yours would give me a starting point. I was hoping to convince my local surfboard shaper to CNC.😀

@@Launchie I actually started with a Naca airfoil and expanded it. I am about 15 inches at my deepest point.

@@The-virg any negative lift possibilities?

@@Launchie doubt it being that there is only air flowing on one side of the pod. The goal was to keep air attached along the entire length of the pod to reduce drag. I am gonna do some testing with airflow and smoke wands. If it needs it I may add some vortex generators to keep air flowing smoothly.

The pod contacts the frame at the attach tabs. 22 of them. It is isolated using rubber grommets at each of these locations.

@@The-virg Thanks, always wondered how to keep the steel away from the panels.

Follow on question. Have you considered using fiberglass as the first layer of the panels to provide the electrical isolation?
