    Baumann Floats for Taylorcraft

    Hi everyone...

    Iíve been looking to get floats for my BCS12D-4-85 for a while. Found some Baumann 1420s and the rigging is unknown, but is suspected to be from a Tcraft. Does anyone have any pics of the front mounts or dimensions of the struts? Even some Baumann front mounts for other planes might help narrow it down. Also, would anyone know where I could find the drawings and assembly/parts diagram for them?

    Thanks!

    The picture two post up of the red and cream t-craft is me how cool. N43336 has an 0200 in it and those floats are Baumann 1420. I took them off and installed the 1500 amphibious floats but never got them certified. I probably would still own the plane if I had kept the 1420’s. You won’t find a better floatplane for the money than a tcraft on those floats. I actually in the end had edo1320’s back on it when I sold it. Night and day difference at gross weight.

    I did a DER approval for an F21 with the Bayman. 1500 amphibious floats. Feedback from the owner was positive.

    DGA those amphibious floats where mine that I sold to someone in Illinois who then sold them to the guy you worked with. I should have tried to find a DER and done it. However the floats were worth more than the plane! Only thing in aviation I made money selling was those floats.

    Yep, I got those floats on. Been to the end of N. America twice with them. Putting them on for the season in a couple of weeks. 95mph on floats and off the water in 10 sec. Thanks again Dave.

    I tried calling the new STC holder, Basler Turbo Conversions, even though I’ve read they will be no help. No answer and I can’t leave a message. I also talked to Joe Birkemeyer hoping he may still have something to do with the STC. He doesn’t, and said it’s probably no use to go the Basler route. He was great to chat with though. He said the 1420s have different rigging than the 1500s, so that is good to know. I’d hoped he would still have copies of the drawings and installation manuals, but he doesn’t. Funny thing, he gave me a number for a Dan Gervae as he might have some more info, but the number didn’t work, so then I hop back on this thread and who do I see posted above!

    Anyway, it’s looking like the STC is a no go (thanks Basler!), so the only option would be a field approval and I’d imagine I need at least some kind of technical info. If someone has the drawings and install manual that would be appreciated. Heck, even a copy of a 337 that didn’t use the STC would be great. I’d like to pursue the floats, but not if I’m going to get buried in bureaucracy.

    You will not get anything from Basler unless you want to buy the whole product line for $500,000. I know from experience. There should be a copy of the STC from some one on here. I may have one for 1500s but not 1420s. I will look and send you the dimensions and pics this weekend.

    Thanks Dan, that’ll sure help in the IDing of the rigging. The front mount bracket looks the same, so that’s good. My buddy should be going to measure them this weekend, so I’ll pass him your pics.

    Oh crap. Glad you said that. Joe Birkemeyer said the rigging for 1420s and 1500s is different.

    Some of this may help especially the float deck angle. Remember the Taylorcraft wing incidence is +3.8* over fuselage C/L. The 3.5* mentioned may be for a PA-11 which has Piper's ~+2* (IIRC).

    Don't let those floats get away. Baumann made some nice floats and they are no longer being built. Their value will hold. You can figure out how to install them later.

    I’ve got drawings and paperwork including STC. If I remember correctly, the STC covers 1500 and 1420’s. If you end up short paperwork let me know and I’ll dig mine out- it’s at my IA’s house.

    Another rough estimate of strut length...blow up the pics and scale each length to the known strut width. Dan's #13 pics are good. If all else fails I can find a local and measure.

    The drawings would be awesome. I’m talking to my IA back home, and he says that without the drawings, there is not much we can do.

    Ok. Give me a couple of days. I’ve been able to make full size copies at the FedEx store, so hopefully I can still do it.

    Dan,
    When I did the approval for the 1500 amphibious for Jim, we used the same rigging as the 1500 straight floats. Jim should have the drawings for the 1500s.

    The rigging for the 1500 straights and amphib was the same. I should have drawings for both but they are plan and side views and BOM but no rigging dimensions.

    If you look closely when Baumann removed the 1420’s from my plane and installed the 1500A you can see the rigging back to the rudder is different. I sold the 1420’s to the mechanic who bought my precious t-craft I can look up the old n number tomorrow and you can track down the current owner or try the owner of N43336 and see if the still have the drawings and stc

    I would definitely be best for you to find that Tcraft with the 1400’s Joe B had to completely recertifications the Tcraft when they made the 1500’s (he used my plane to do it ). I can help you in any way I can as far as relevant similarities go...my plane is right outside my door if you need other pictures.

    I'm confused about the differences between the 1420 and 1500's. Can someone explain? Why were two models produced?

    Thanks Dan. As of now, purchasing them is on hold until I can find drawings and/or an installation manual. So any leads for 1420 drawings or other info would be much appreciated.

    Gary, best I can tell is the 1500s are a foot shorter and slightly fatter because there were some complaints about the float tails dragging on takeoff. Also according to Joe Birkemeyer, the rigging was lengthened to raise the plane and help with wing clearance a bit and the angle was changed because they floated at a different angle. My guess is they also had to change them a bit when they were designing the amphib 1500s.

    So basically they built three floats...the 1420's originally followed by the 1500's and amphibs? I talked by phone with Bud but not Joe years ago. It was confusing even then about the evolution and changes to dimensions/fittings. I guess today prints and paperwork would be important to do the installation. I'd rather have the longer float after walking back on the three sets of EDO 1320's I've owned and watching them sink. There's a need for monitoring aft CG when loaded or submarining the bows when light at forward CG on the similar EDO's.

    My IA is going to look at the drawings this afternoon and see if they cover the 1420’s as well as the 1500’s. I actually sent a set of drawings to a shop on Lake Hood 2 summers ago that was putting a PA-11 on 1500’s. Can’t remember the name but they’re right down close to where Ketchum’s used to be. Anyway, I’ll let you know later today.

    Sorry EdH, my IA just called and said the STC covers 1420’s and 1500’s, but it calls out for separate drawings. The one I have is for 1500’s.

    Ehh,

    I found the STC and it covers 1420 and 1500s. I have drawings for 1500s so it would require a title block change. If you do buy those floats, I can send you dimensions for the bottom belly panel. I just made a new one.

    Mark and Jim, I appreciate y’all looking for me, too bad I didn’t find a set of 1500s. Someone has to have the 1420 drawings and install manuals, seems like those are the key for me right now.

    With that knowledge, you can contact the FAA controlling office of the STC. Their address in on the STC. Look it up on FAA.gov. They will be able to supply you with the information and drawings which you need. They may have you get permission from the STC holder for them to release the information to you. You may have to go to your local FSDO to view the information and may possibly be required to order the information through your local FSDO. If you are nice to them they may even let you make copies on their copier machine. Have your IA contact his PMI. That is one of the duties of the PMIs to assist the IA.

    No one here has mentioned the STC number. It should only take a couple of minutes to find the controlling office once the STC # is known.
