    Note from Mark

    Greetings to everyone. It has been a few months since Virgil took over the kit company. I wanted to express my thanks and appreciation to the many kit customers and scratch builders who turned into good friends. For me, the biggest benefit of 23 years in the airplane kit business has been the...

    new carb heat box control

    A couple days ago the first plane flew with the new carb heat box Bob designed. He saw that as the airspeed went up it tended to move the flapper and the control cable out and have carb heat come on. For a control cable for the new carb heat box - use a ratcheting control cable or the...

    Fuel injection induction system parts for Model 5

    Wanted to let everyone know that these induction parts for injected engines for the Model 5 are now available. A cone shaped K & N filter is used. This system is flying on two Model 5's, and working well. The alternate air function seems to work fine, and at high airspeeds it seems to give...

    four place Bearhawks coming to OSH

    I thought I had arranged for a nicely finished four place BH to be displayed in our booth at OSH. However, the owner can not come this year it turns out. If you are planning to attend in your four place BH and would be willing to allow us to display your plane in our booth - please get in...

    The newest kits include new items that had previously not been included with the kits. We call these kits (4 place & Model 5) the Advanced QB kits. One of these items is the 3/8" tubing for the fuel lines & 1/4" tube for brakes. Since I do not have a plane here to take measurements - I...

    new carb heat box

    Here are some pics of it. I really need someone to trial fit this before we make a bunch of them. We need to make sure it fits within the carb heat box "cover" aluminum part we have been sending with the kits.

    new carb heat box

    Today Bob received the latest carb heat box from the kit factory. He is 100% happy with it. However, it is not too smart to just make these without someone actually trying it on an engine AND seeing how the carb heat box fits the cowling. Bob THINKS it will be fine. But we need someone to...

    December 2022 factory visit

    Good evening everyone. I thought I would give a brief report on my recent visit to the kit factory. One main objective was to show the guys how to install the boot cowl sheet metal. We want builders to just pull out the sheet metal parts and have them 100% trimmed to fit and can be cleco'd...

    gas cap discussion looking at filler neck I.D.

    We (the forum) have spent a bit of time looking at gas cap issues. One variable that could be affecting everyone's experiences is the ID of the filler neck. I assumed (incorrectly) that the ID of the 2"x.125 wall tubing would be very close to the 1.750 spec. I thought it would vary a few...

    Choices for OSH get together

    You guys please help me decide between two options for a get together at OSH this year. Option number one - after hours at the booth everyone can come by for an hour or so. Maybe 5:30 - 6:30 on Tuesday evening. The EAA does not allow food or drink at things like this unless they arrange it...

    Trim system parts in hor stabs

    Over the years we have seen some cases where the trim "arms" in the hor stabs get play in them where they are bolted to the 1/2" x .035 tube that runs inboard through the hor stabs to the trim horns in the fuselage tail. The plans show that arm welded to the 1/2" tube, but we have always sent...

    Angle valve cylinder Lycoming 540 baffling

    Just wanted to let you Model 5 builders know we are working on a baffling kit for the angle valve 540's or 580's. A friend has a CNC router and he is almost done setting up the .dwg files to cut the patterns supplied by Collin. My friend is extremely qualified to make a good baffling kit as he...

    Model 5 excess lead weight in elevators

    The factory has been putting too much lead in the elevators of the Model 5 kits. Those of you with kits will need to drill some out. Somewhere around 1/2 lb. But you need to balance your elevators properly and determine how much lead needs to come out. What happened was a stupid mistake on...

    new shoulder harness tabs welded in

    On the latest batch of kits we started welding in tabs for a shoulder harness for a 4 point harness. As well as the across the shoulder harness tab that has always been there. So now builders will have a choice without doing any welding. Mark

    LSA do Brasil

    My distributor in Brazil, Alex Henriques de Barros, has recently finished and flown his BH LSA. He is very happy with how it flies and is working out a few bugs. He has a Bob Barrows O200 like mine and the same Catto 76 x 44 prop as well. Will report more info as he gets some time on it. Mark

    O-360 Angle Valve 200hp Cooling

    Here is a pic of what I did on my (now Jared's) O540 powered BH. It has always done a good job cooling the oil. It does have a 3" scat tube but the baffling is quite well sealed and the "plenum" in front of the oil cooler makes sure the air spreads out and makes use of the entire face of the...
