RE: Fibreglassing over Balsa

Which PU product seems to be the popular one to use?

Most use Minwax Polycryilc.

Is the surface of a WBPU as hard and tough as a surface done using epoxy?

No it is not as hard as...

RE: The Scratch Plane featured in Fly Rc

Thought you Scratch fans would like to see the latest edition, the Micro Scratch. Made from a single sheet of 1/32" balsa and powered by a Park Zone system taken from a crashed Park Zone Cessna. 15"...

RE: The Scratch Plane featured in Fly Rc

Yes, a short kit will be available very soon from 3DX Hobbies. I'm cleaning up the cut sheet files now. Basically, have to put some part numbers on the pieces so it's easier to figure out what is...

RE: The Scratch Plane featured in Fly Rc

The motor is A BP U3520-6, a Turnigy 80 AMP ESC, and a 4S2P - 4400 MA battery all turning an APC 12x8E prop. I'm also using a separate 5 amp BEC. System puts out between 650 and 675 watts.

RE: The Scratch Plane featured in Fly Rc

Yeah, I changed the structure on this one because of the size as I wanted to keep it light. Here's some pic's before I covered it.

RE: The Scratch Plane featured in Fly Rc

For you Scratch fans, I built a Super Scratch. 60 inch span, 650 watts of power. Flies just as great as the original.

RE: 1/64 ply substitute

Ditto on Dsegal's recommendation. I have generally stopped using ply doublers on the fuse of my electrics and now use balsa. Electrics run with minimal vibration and the balsa doublers have worked...

RE: Probllem with airplane roling without cause

How heavy is it? Sounds like it may be stalling. A heavy plane will have to fly at a greater angle of attack to generate the necessary lift and if you pull back too hard on the stick it can stall...

RE: The Scratch Plane featured in Fly Rc

I sure the air frame can handle the power.  My main concern would be the weight.

RE: Airfoilz RCU Extra 260

If you are really a hard core 3D flyer then you might notice the speed difference. Otherwise, they should work fine.

RE: Airfoilz RCU Extra 260

You could try it. Just check the amps. Should have lots of power, but top speed would be lower than with the 11x7 though. Depends on the flight characteristics you like. I like a little more top...

RE: Airfoilz RCU Extra 260

Your Rimfire 35-30 should work fine. I would try an 11x7 prop with at least an 1800 mah 3S pack. I've flown the Extra with over 350 watts.

RE: How does carbon fiber veil and dope add strength to balsa?

It adds a thin rigid skin to the balsa that helps reduce the deformation under load. The control line guys use it all the time particularly on their stunt planes. Make a great base for finishing as...

RE: Build Thread: Airfoilz Full Fuse Yak 54

I have been using an AXI 2808/24 with an APC 11x5.5 E Prop cut down to 10.5 inches dia, a Turnigy 35 ESC and Zippy 3S 2200 pack on the original RC Group prototype. Great performance with that combo....

RE: Rib Spacing Question

I'd go with the foam core wing. I'm building a smaller version and that's what I did. Very rigid and pretty light. Mine is in primer, getting ready for color.

RE: Paint Question

<I understand that latex paint is heavier than epoxy. Is this true? >

Generally, a latex finish is lighter.
