F21b floats

[FbksFlyer]

Hi everyone. I'm about to purchase a 1990 F21b and I'm wondering about float options. I'm assuming that PK or Baumann 1800s are the ones to watch for. How hard is rigging to find? Has anyone ever had or seen an F21b on floats? What were they?

Baumann 1500's would be the ticket, if you can find some. Aqua 1500's have been used a lot on 19 and F21's, PK's will also work. Call Eddie Peck at Peck Aero in Canada, He may be able to steer ypu in the right direction.

Thanks, someone else suggested those too. However the 21b is 1750 gross so I think 1800s might be the ticket. I was hoping to hear for sure; I'll get in touch with the folks you recommended. Thanks.

The baumann 1500 floats are approved for the f21-b They have over 1500 lb capasity per float not both together.

Far part 23.751
'Each float must have 80 percent in excess of the buoyancy required by that float to support its portion of the maximum weight of the seaplane in fresh water'

Re: F21b floats

Wow, that's government wording for sure! I understood the concept it describes but hadn't looked up the reg. As far as I know, if I were to use 1500s my gross weight would be limited to that, which would waste 250 pounds of useful load and make it harder to stay legal. I have seen an F-19 on 1800 floats, now I am wondering if the rigging would be identical. As far as Lance's link from above, notice that all of the airplanes listed are 1500 and below gross weight. The F21 is listed, but not the B model which got the GW increase.

Re: F21b floats

If I were you I would go with 1800 to make good use of your GW increase. My boss said the PK 1800's are approved for the T-Craft, but I guess i didnt realize there were different models of the F21. I think the rigging would be the same, I will have to do some more looking around to see about the models approved.

Thanks Levi. I'll be saving my money and watching for 1800s I think.

fbskFyer, Open this link...there was a set of PK 1800's for sale here in Ak about a month ago:

They said the setup was for a SuperCub...since the Cub is narrow and the Taylorcraft is wide, you should be able to cut the "overly-long"
struts down and make them fit your plane. Check out the link and talk to your mech. Dick

Thanks for the link Dick. I don't know how I missed that ad on alaskaslist since I've just about worn my computer out looking at the aircraft section on there! I'm looking into the rigging issue right now.

Re: F21b floats

For 1750 gross weight each float would need to have buoyancy of 80% which would equal 1400lbs per float. Baumann 1500's have 1536 lbs per float buoyancy an are STC'd on all F series Taylorcraft. I believe you may be correct on the 1500 lb gross limitation on the STC though. I'll check for you.
