Your Kadet MKII and Beaver are awesome. What did you use to mount your floats to your plane? In the photo of the MKII it looks like they are air foil shaped. I'm building a 96" Beaver and am a bit lost as to what to use. I did meet a guy at a float fly that used aluminum air foil shaped struts with carbon fiber rods inside the struts for strength. Also, tell me more about your pink foam floats. I've made jigs to cut 27", 34", and 42" foam floats then I sheet with 1/16 balsa. They are tapered sides and vee bottom. They look alot like the Great Planes floats when done.

PS flynfish is my brother.

It was mounted inside last month, I relocated it to rear when I took the floats off and flew up in miami. it balances better with it there with floats off, but it scares me. The inside mounts are in place and pushrod is on shelf, and I think it would be a good idea to move it before it gets sprayed on!

Status: offline 		Thanks Jeff - Last Post!! Sounds like the end!!! Notice the retractable water rudders! Don't forget to retract them before take-off - they rip out pretty easily on rough water! using "Spider Wire" fishing line through Stainless Steel pulleys from model ship to control them as per full scale aircraft at the St. Catharines airport. A retract servo hidden under the cockpit cabin floor does the job. VEry effective

Status: offline 		It's hard to beat flying off water. Our club hosts 3-4 float flys a year and we have a ball. Most of our members have seaplanes and several live on lakes so we fly off water a lot. I have two seaplanes that are flight worthy now. An Ace R/C Seamaster 120....84" span with a G-38, and a Thundertiger Seamaster 40. Both are great fliers. I have a Pondside on the building boards. It is a 48" electric designed for an 05 and 7-8 cells (I chose an Astro 05 w/8 cells). It's distributed by Hobby Hanger and looks like a Seamaster without the T-tail. I hope to have it finished before New Years Day so I can fly it at our clubs Frost Fly (seaplanes fly great off the snow!!!). I also have a Northstar still in the box that I hope to finish this winter.

Sorry guys this might be a long one!

Have a look at my photo gallery I loaded a quick little drawing on the float system in to it. My self I can not take credit for the system as it was taught to me by Ted Russell many moons ago. It is important to use the pink or blue extruded foam as the white bead foam is not dense enough to support the loads, besides the white bead foam sucks up water like a spong. On the Kadet 3/8" x .049wall thickness seamless 6061-T6 alum. tubing was used.(bought at Marinex a local welding shop that builds alum. boats) Insert a 1/8" x 1/8" spacer strip in side the tube then press the tube flat(I use a hydraulic press a work but a vise should also work). The spacer will limit the amount you can press and when removed will leave a slot for the mounting bracket to slip in to.For your 96" beaver just up size the tubing and maybe the mounting plate thickness, If you want to get carried away you can make an airfoiled shape mold to press the tubing between.(or Sea Commander sells structural tubing). The floats are ether cut on a band saw or hot wired, Epoxy glass the bottom(6oz.glass) and let dry oven night, add triangle stock to the inside bottom front of the float as a spray rail when dry sand to shape. Glass top(4oz.glass) of float. Fill and finish float top but do not paint yet. Mark location for mounting plate slots, cut away glass at slot location and melt the slot with a soldering iron. to glue the mounting plates in mix up a batch of slow cure epoxy and micro balloons (I use West systems epoxy) to the consistency of tooth paste, fill mounting plate holes with mixture, insert side plate then vertical locking plate. Whip off excess epoxy with alcohol (I should have mentioned earlier, make and dry fit mounting plates,spreader bars and support struts before gluing in plates) I usually install the plates with the spreader bars then block and align the floats to dry over night.
I hope that this is helpful to you in this system the foam cores are not sheeted with balsa or ply before glassing and are strong enough to have survived a 100+mph OOPS. with only strut damage.

Cheers : Doug

ps:For larger float increass mounting plates and or tie vertical plates together or as one for a strong back.

Thanks for the info. It's exactly what I need to help finish my Beaver. What an age we live in when we can share info at such great distances. Keep 'em flying......Seaplane

Status: offline 		What is it about float planes that make them so darn cool looking? Seriously, I could look at pictures of our float planes all day!

I have been into RC stuff for nearly 20 years (2/3 of my life) and have just recently (past 5 months) gotten into planes. My first was an electric Kavan Wingo on floats (Hobby-Lobby) that I learned to fly at my parents' lake house. I quickly moved up to a Hobbico Airvista with GP 40 floats and OS46FX. I sold that to my brother and bought a SIG Rascal 40 and put a set of GP 40 floats on it with a 46FX (never got it to fly right ;-(. Then I turned an electric Scorpio ThreeDee 400 into a glow float plane with the Wingo foam floats (perfect match). I am getting ready to build a SIG Somethin' Extra on a set of GP floats. And, after seeing all of the photos, I am going to have to add a Cub to my list in the near future.

There is nothing quite like walking down the back yard and onto the dock with floater in hand. The neighbors love it! I enjoy flying at the field, but the water makes for an entirely different experience.

Status: offline 		I love float flying too. My first attempt was my own design foam floats on a Sig Kadet MKII. They were too tall and too thin so they sunk in the water a little too much. Attempt no. 2 - Wider floats not as tall. Those worked great! Then I put a set of Goldberg Superfloats on my plans built Cloud Dancer 60. That worked great too. In the air in 50 feet on only a plain bearing 60. Then I built a Hangar Designs Sea Cruiser II. That is a blast. It flys a lot like the stik type planes. That is my only float plane now. I sold my boat, so it only gets several uses a year.
