Very nice Joel. Nice to see all balsa for a change. Hows it fly?

I was very pleased with the performance. Takes off faster than my friends puddle jumper, and has a great rate of climb. E-calc says around 1350 feet a minute. It has a glider airfoil so it has a very low sink rate.

No, It's my own design, but I hope to kit this plane a few others someday.

Way cool! Looks like you designed a fantastic plane. Man, I'm lookin', but I can't see the answer. How does the wing attach? Is the battery swap with a hatch in front of the wing? Kinda hard to tell.

The battery hatch is just above the numerals on the fuselage. The wing is held in place with the traditional method of pins in the leading edge and 2 nylon bolts. They match the wing color so they are hard to make out.

Joel,

Really nice lines: sleek hull and relatively high aspect ratio wing for a flying boat. I especially like the streamlined wing mount pylon, and very clever and strong battery tray.

Great job.

Very nice design. I have a PuddleMaster and I can see that your plane would be cleaner.

Why did you use transparent film on the top of the wing over the sponsons (floats) ?

The servos for the ailerons are located in the floats. The clear covering allows me to see if there is water in the float that might effect the servo.

Very clever use of the space and an "enlightened" way of checking for water intrusion. Excellent design feature.
