    ​If I remember correctly, they're just a little short . . .

    The 2700 Amphibs are small as Griz said. They originally had electric motors and actuators. I think the motors were made by a company called Lunch or Bundy in New York. In the 1950s. Most that are still in service have had some sort of Wipline
    conversion for the gear motors. There are always a group of people trying to find parts for 2700s. There were also 2705s which had hydraulic gear motors. The landing gear on them is kinda like the 2790s.? Horrible... installation will reduce your legal gross weight. And they stink for getting out of the water. By the way, the 2700s are the same size as the wonderful Edo 2870 floats. They added all the gear and motors to ruin them. The Edo 2790s are just Edo 2960s with Amphibs gear added. In planes like my 180 with the gross weight increase, I need at least 2960s. The 2790, 2870, and 2700s limit the gross weight to a lower number.

    By the way, the great 2870s are 378 pounds installed weight on a Cessna 180. The 2700 and 2705s are around 560 to 580 pounds depending on electric or hydraulic.

    The set I'm looking at are still electric. I sure wasn't expecting stellar performance! just the convenience of having wheels. I've already got a set of 2960's mounted on the 180. wasn't going to get rid of those just yet.

    what about the gear system, other than the electric motors, are bad

    The 2700s were introduced in 1955.
    1. Hard to find parts
    2. Reduced buoyancy
    3. The rear gear wheels make drag due to their position.
    4. The nose wheel assemblies are known to be troublesome.

    There was a set for sale down in WA state a little while back.

    What year / model is your C-180 ?

    There was a set of EDO 2790s ( 2960s with amphib gear ) for sale someplace up here this summer. They have basically the same problems, with more flotation.

    There was also a set of WIP 3000 amphibs in Brainard Minn for sale. Expensive, but a very nice float for a C-180. I thought long and had about those but did not want to give up a seat space in weight.

    I should have said reduced payload above and not reduced gross weight. (at least on the older model C-180s) The EDO 2700s in the older model 180s still had a 2850 pound legal gross weight. They ( the amphib floats) just weigh a bunch more. I think that when you get up around the G model 180s, they list the 2790 EDOs as being the amphib float on the type cert.

    One big selling point of the 2700s and 2790s is that they are about the only affordable amphibs on the used market.

    My C-180 has a gross weight STC with the 185 tail.. So I have a 3190 pound gross weight. BUT if I installed EDO 2790 amphibs, I loose part of that legal gross eight increase, per the STC.

    Wow, I was just looking for what a set of 2870s weigh the other day. Kenmore doesn't seem to list it in any of the edo docs.
    And on that note, holy crap. Those are only 22lbs lighter than an amphib clamar float of the same size.

    I've got a plain, no mod 64 E model.... fixing to going on a little diet this winter. Its got a lot of tired bits that aren't needed so they are coming out.

    These are affordable, which is why I'm interested in them.

    The 2700s should work.. Or the 2790s. The 2790s use a what is basically a reversed Scott 3400 tail wheel as the nose wheel. I think I read someplace or another that you can use the Alaska Bush Wheel big fork or a Gar Aero fork on the 2790 Amphibs. That would give you a fat front tire and that would help a HUGE amount on gravel or grass. ( Amphibs being a paved runway deal most of the time.) The 2790s and the 2700s more complicated nose wheel assembly takes up shock, ( when all the parts are working) They were developed back when there a lot more chance of rough runways being used by your average pilot. The Wip and Aerocet front gear legs are stiff and like smooth pavement.
