THE BUILD HAS BEGUN

After looking over all the drawings, I've decided to start on the float kit... Definitely will be the most difficult and time consuming part of the project, especially with the retractable gear, retractable water rudder and servo actuated brakes on the rear wheels to act as steering

Plans say 7lbs for the floats, 12lbs with gear, servos, air tanks, rudder, etc. A few places to shave some weight, but it'll be a couple ounces, not pounds. After seeing the drawings, and the size of this plane, strength will be important.

Pictures tomorrow AM - glue is currently drying

Re: Beaver Fever in Southern Ontario

Another great video of Beavers with some cool scenery:



Man, vimeo sure kicks utube's a$$...

I love these airplanes. Not sure why, just do. Gotta be on floats with a round engine on the front...

Re: Beaver Fever in Southern Ontario

Last night I cracked open the box and rolled out the plans... very cool design and really like the way the floats have nice beefy backbone I-beams!! I used to fly a ton of RC Float flying and have seen many floats break or weaken over time and the bending along the length of the float is huge, especially if there's a few poor landings.

Re: Beaver Fever in Southern Ontario

Really impressed with the wood in the float kit Very clear balsa and nice quality laser cutting. All the plywood is really straight.

Unfortunately I'm missing a few pieces of wood and right now only have enough to build 1 full float. I'll call National Balsa today and will have them send me the missing pieces. Here's what I'm missing.....

2nd pic - should be (2) of the large sheets of laser cut 1/16" ply (I only have one)
4th pic - should be (2) 3" x 1/4" x 36" laser cut balsa (I only have one)
4th pic - should be (2) 4" x 1/4" x 36" laser cut balsa (I only have one)
not shown - should be (4) big laser cut blocks of basswood (I only have two)

Re: Beaver Fever in Southern Ontario

Here's a few shots of the retracts for the floats. Very, very cool

Also shot a picture of the water rudder. It is connects to the retracts with a Nyrod so when the gear goes down the water rudder will go up

Re: Beaver Fever in Southern Ontario

Here was the start of the build

I got the main I-Beams fab'd up last night. Each pontoon requires (2) of these I_beams. Unfortunately the wood I'm missing is to fab up the second set of I-beams.

The thick areas in the I-beams have a basswood filler (not balsa) and this is where the retracts bolt to A very nice design.

Re: Beaver Fever in Southern Ontario

Hi Trev,
check out this site: firgelli.com.
they are a canadian company that makes electric retract servos.
maybe you can adapt them to the Sierra retracts to save some weight in the floats. The company is located in BC.
Larry has these actuators in his beau fighter.

Re: Beaver Fever in Southern Ontario

WOW! I can't believe I missed the unveiling of your beaver!
I see you already have it spread out and have the wood almost ready to go!
Sorry to hear that you came up short with your wood!

Too much soft wood is no good
Short wood is worse on a beaver
