I'd guess that it isn't the foam used, it is the components and engineering.

The way this thread died, I'd guess the guys ran out of patience. Reading between the lines, I think I'll go get a Multiplex Mentor. If you are looking for a good first plane that flies on floats, I've had good luck with the Hobbyzone Super Cub. The floats work, and they're only another $25.00.

I maidened mine yesterday. I loved flying it, very docile and a relaxing plane to fly. Plenty of power, I ditched the 3 blade prop for a 2 blade can't remember exactly what size. The main wheel covers suck they rotate very easy, but no big deal. I don't intend to fly off water and I don't have a set of floats for it, but off of land I thought it was a great plane.

I got mine from TOPRC in Auckland NZ http://www.toprcmodel.co.nz/
They sold out of the first shipment in less than a week but will have more in July
They sold for $99 NZ
It flies very well - would make a great second plane or first if you take it easy

That makes me wonder if the designer moved the floats so far forward in order to try and effect balance without adding a ton of ballast. I was encouraged enough with the excellent flight characteristics of this to go ahead and work out the issues with the floats. My guess is that I'l need to cut the step straight across, mount them about 2" rearward and hide significant lead in the tips. I'll post my results. In the meantime, I'll probably use this thing as a winter beater plane because it flies so nice.
My instructions call for the CG to be 78-84 mm behind the leading edge. When I tried to fly the plane it was obvious that the plane was very tail heavy and almost impossible to handle. I had a minor crash, just broke off one of the float tabs and the prop. My lucky day.

Can anyone verify the 64mm CG? I know that I have to move it forward just would like to know what others are doing.

You have already found out the supplied prop adapter is junk. The prop shaft can be cut to the proper length with a dremel and cut-off wheel.

The floats are designed wrong. They don't work as they should. The step is in the wrong spot. Too far forward. Don't use them without modification. Read the whole thread and you will see how Brent and I both had bad experiences with them. I've gotten around to starting work on the floats. Below is the before and after shot on the step extension. I'll use them for flying off snow for the winter, but water trials will have to wait for May.
Mike,

Did you finally made some tests with the new designe of your floats ?

399Dan - "Did you finally made some tests with the new designe of your floats?"

I have just finished installing the water rudder servo on the bottom of the fuse with Spiderwire pull-pull cables threaded through model ship rigging points. This should keep the water rudder servo high and dry. I'll be giving it a test from the water next weekend in northern Maine.

BTW I never had any documentation on this plane, so I arrived at the 64mm from leading edge from careful measurement and calculations. It is neutral in pitch upright and inverted at this point. You might even like it farther forward. I'm not suprised that Edomodel would come up with such an outrageously bad recommendation, as they got so many other things dead wrong.

Thanks for the confirmation on the 64mm.

I fixed my floats and found the plywood block that the rudder attachés to was falling off. It appears they used some kind of contact cement to glue all the wood to the foam. While testing a 2 bladed prop the motor mount came loose from the fuse, collapsed, and came apart. The prop hit me in the arm and it took me over an hr to find the motor in the far corner of the garage. No stitches required but I do have an ugly spot on my forearm.

Have it rebuilt now and will move my CG. Hope to try it again next week.

Anybody know who carries this C-185 in the US? I have not had good luck with overseas shipping of aircraft kits, parts yes, but complete aircraft, no.

Thanks

I didn't have a problem from China with RC CASTLE on this one.

But I think banana hobby or nitro planes has it.

With the floats on it looks like I need 2oz of weight near the front of the floats to get the 64mm CG. Does this sound about right? With the floats on the plane seems to hang close to level and stable over a fairly large area.

Sounds about right.

I had balanced mine with some lead in the nose to get to 64mm CG while on wheels. I installed the floats and had to put one ounce on the tip of each to maintain the balance.

With all the extra weight I'm thinking of propping up from the 11 x 5.5e to a 12 x 6e for extra power. Will report back after this weekend's test flight off water.
