I'm starting LSA gear fab and had a question for guys with higher time Bearhawks. How are you handling lubrication of the gear mount bolts and have you noticed any play/wear developing in the gear leg bore or bolts?

I'm about to start the landing gear on my LSA and noticed there isn't any bushing incorporated into the attach points. Has anyone flying a higher time Bearhawk noticed any play developing in the landing gear attach points? If so where? I see posts on the cub forum regarding gear attach point...

I'm curious to hear what fellow builders are using for floorboards in their Bearhawks? The LSA plans show several different thicknesses of aluminum. I've seen plywood, carbon fiber, or aluminum used in cubs. I read in a forum that someone had used some small beads of silicone between the...

I just stumbled across this Corvair powered LSA over at Flycorvair.net https://flycorvair.net/2016/07/01/ho...ge-6250-miles/ Great to see another LSA being completed. If you click on the image it is viewable high res.

BTAZ Looking over the plans and booklet I'm assuming the thrust line is 0 degrees? The Patrol plans show a -1 deg thrust line on the three view title page, and the side fuselage layout. The LSA only shows fuselage center lines. I don't see anything directly specifying the thrust line.

This isn't Bearhawk related, but I stumbled on it this evening and had to share. This guy built a Nemesis NXT and put a twin turbo 720 on it. Very impressive. ​​ Maybe an engine option for the Expedition Chris In Marshfield ? Teaser video: https://youtu.be/MkBb9u_3qXk Engine run up...

I was reading through my plans and didn't see much detail on the horizontal stabilizer strut for the LSA. Someone asked about it a couple years back in the LSA forum, but it didn't seem like they found a clear answer. (...

Can the control torque tube (the tube that runs under the floor and holds the control sticks) be removed after fabric is in place? Looking over the plans and build photos it looks like you may need to install the torque tube before fabric?

I've always wondered about this... https://youtu.be/ftq8jTQ8ANE

It would be excellent to see some additional video of the LSA. Loading, startup, taxiing, takeoff, landings, etc. If anyone has the opportunity to take some video, and doesn't have the resources to edit or post the footage, I have some decent video editing software and experience uploading...

Does anyone know of a source for ground and threaded 1-1/4 axles with 16tpi? Aircraft Spruce sells 1-1/4 x 12tpi. Both the plans and Matco spec 16tpi.

I'm at the point of deciding which tail spring mount to fabricate on my LSA. Plans call for a tapered rod spring with a welded in mount. The design looks very clean, light, and low drag. That being said, the only spring/suspension option for that setup is the round spring. A standard leaf spring...

Does anyone know what type of fuel selector valve Bob used on the LSA? From the photos it looks like a 4 way selector valve you would find at a marine supply store.

Wayne Massey listed the wheel, brake, and tire setup he is using on the LSA (I believe Bob's prototype and Mark's use this same setup as well) in a previous thread: http://bearhawkforums.com/forum/bear...sa-kit-started) Matco 8" wheel and brake with a 21" tire. Matco lists this setup as weighing...

I called and talked to Continental regarding their current new O-200 offerings for the experimental market. Pricing is for stand alone new engines, and no core or core charge is required. The rep was very friendly, helpful, and willing to answer questions. Weights include accessories, no...

I can't find anything indicating the angle of station C-S. I see the bottom gear shock strut fitting is angled to 18 deg, and I'm assuming the C-S should match that. Looks like BTAZ matched the angle of the front door frame, which looks to be around 17.75 deg. Can anyone point to where this...

I needed a compact cart for a small wire feed, and TIG welder. Many of the ones I found placed a single bottle to the rear of the machine. This made the depth of the cart too long for my application, and I needed to hold two bottles. (argon and 72/25) This is the design I came up with. When...

I appreciate the ideas, experience, and resources that the Bearhawk community shares with each other. I will be posting my experience building the LSA in this thread, and hope fellow builders find it enjoyable and useful. The fuselage will be constructed using the Bearhawk tubing kit. Build...

Has any load testing been done on the LSA wing? I found the static load testing that was done in 2002 on the 4 place Bearhawk, but can't find anything on the Patrol or LSA.

(All dimensions are approximate and for rough comparison only) (See side view photo bellow - click on photo thumbnails at bottom for larger view) 6'4" 195lb pilot and 5'7" 130lb passenger shown. The LSA occupants are drawn in white with black outlines. The pilot in the LSA is situated in the...
