The best floats for 1976 C-180
Author Last Post
the edo - 2870  Faster take off and great performance .
 
Do not do Edo 2960's as you will regret it. The back length of the floats dig into the water on takeoff.

Well, I kind of like my original Edo 2870s. The work fine for me. I’m kind of partial to them actually. Call me nostalgic.

This is an old thread but nothing has changed.

Most people can't spend big money and get nothing but novelty in return.

I have seen Cap 3000-E which are 3300's haul 1575 lbs  with a stock 0470-S mid 70's Skywagon.

Do the math doesn't count for SHi$ when you can't get off the water with Edo's.

And Caps are faster and look better.About 2003 there was heavy waves against the Oshkosh Sea base.

Special permission was given to depart inside the bay by being towed back in the creek.

We watched most float planes depart and non lifted off before the cut except a 180 with Cap 300 floats.

This rig held 6 5 gals of gas and 4  aboard + gear. By going to the step with no flaps,then 10 degrees until

47 MPH was reached, then 40 degree flaps lifted this off at the gap.

All the 185's, and some with one or 2 aboard banged against the waves for a ling time after the gap.

I have a photo I posted on here at that time of this Wagon departing just before lifting off inside the bay.

Allot of good posts were lost with good mechanical articles before this was ruined.

happy day, lew

My cap 3000D's weigh 422.5 pounds installed.

My weight & balance lists 378 lbs for Edo 2870 floats.

Anyone out there know the real weights for Aerocet 3500L's, CAP 3000's, Edo 2870's or Wipline 3000's? Are they all around 420 to 450 lbs? Thanks. Crash
 
You don't actually gain 300lbs. GW when the floats are on. The GW is just increased to compensate for the weight of the floats because they produce enough lift to negate any weight penalty they would incur, keeping you from losing 300lbs. of usable load.
 
My POH for our 1960 180C also reflects a higher permitted gross weight on floats. Nature of the beast. We like our Aerocet 3500Ls just fine.
 
I have a '57 C-180 that was on CAP 3000's when I purchased it (I chose to buy it on wheels only). The GW for this model C-180 on wheels is 2650 lbs. I noticed on the weight and balance sheet that the GW is listed at 2950 lbs when on floats (CAP 3000's) and 2650 lbs when on wheels or skis. The panel is even placarded with this weight. Is this correct?

Do you gain an additional 300 lbs in GW when CAP 3000's are installed on an early model C-180?

It doesn't have ART tips on it so this is not where it is coming from either.

Thanks.

Hey MikeV, the cap 3000-E is 422 installed.
What are the 2870's ? Another item , Cap is in limbo again for parts availability. So privately , they work OK for me,
If I were a commercial operator, I might wonder about that..

Mike,
Will there be an article in Pilot Getaways on float flying in the future? I really enjoyed the ski article that was in the last issue. Az folks don't get to think about ski's much!
 
Lew,

You won't find any arguement that the CAP floats are nice floats. My ONLY complaint about them is that they are heavy compared to 2870's.

Otherwise, they perform well, they get out of the water really well, they handle rough water very well, and so forth.

But, they are a lot heavier than 2870's.

Mike V
 
Look at the lines of these Cap 3000's...3300's actually.
If I bought a plane with ugly floats, They would be for sale in a minute and I'd put these on...allot for the money.
You heard of short landing contests, If there was one for hauling loads, I would show up with this little sister 180.
I dont know if one model does everything, it would be nice to have flat tops-hatches-or dream of amphibs..

Yes, but all this says is that all models of 180 are approved on Aerocet floats. It doesnt say that the Kenmore gross weight stc is approved on all models of 180, and I don't believe it is.

In addition, if the aircraft doesnt have the big vertical fin, I don't believe the Kenmore upgross stc applies either.

Check out the Kenmore stc. It used to apply only to late model (H and up, as I recall) airplanes, and only airplanes with the 185 style vertical fin.

That was as of a number of years ago, so things may have changed.

I would still have trouble finding fault with a good set of 2870's, combined with a decent fairly light airframe.

I e-mailed Aerocet asking if they had an STC based on Kenmore's and Matt Sigfrinius e-mailed the following back. "Absolutely, we have piggy-back STC for the Kenmore up gross kit. 3190 would be your max takeoff weight. I could send you a copy of the information if it would help." I asked him to please send a copy of their information and he faxed a copy of Aerocet's STC # SA00137SE for type certificate # 5A6, for Cessna Models 180A-180H, 180J and 180K on Aerocet Model 3500 or 3500L floats dated January 24, 1995 and January 22, 2001. This STC with Kenmore's gross weight STC allows the operation up to 3190 lbs. on Aerocet 3500 and 3500L floats.
I didn’t know that the earlier model 180s were included in the Kenmore STC but they are listed in Aerocet’s STC.
www.Aerocet.com is their site.

This came with cap 3000's. The skins are flat, they look good, and are not the slower floats around...
The steering at taxi is not great , but I heard there are stronger springs made for cap floats..

I'd concur with everything Randy K noted reference the 2870's. They really are the best floats for a 180. The CAP 3000's are also great floats, and perform really well, but they are significantly heavier than a set of 2870's, so you'll give up some useful load. I wouldn't discount them, though, if the price was right.

I'm not a big fan of 2960's, though they perform well if you learn how. They also require a ventral fin on most late 180 installations, I believe. This fin isn't a really big one, but lots of folks just don't like ventral fins at all, for some good reasons.

As noted, if you can pull the cash for the Aerocets, they are truly the Cadillac of floats in this class now. They perform well, they hold up well, and they are big. That said, they are substantially heavier than a set of 2870's. They are also substantially slower through the air, due to their size. They are big.

Do the math, and you may find that even with the Kenmore gw stc, if you put a great big set of floats on the plane, you will not have gained much in the way of useful load.

Take a look at Aerocets STC. It is possible that their STC allows installation of their floats with a higher GW if the Kenmore STC is installed. STC's piggy-back on other STC's all the time.
