Just can't live with that.
Run at 60 hz and get rid of prop vibrations. The quad guys have many more advanced solutions such as gels and things to dampen the vibrations.

I have 2 GoPro so I should be able to do it I'll try to do so tomorrow.

Yeah there's still some ice here and there on lakes, this would probably be doable but for a maiden flight I prefer not to do it... I'll do it when the plane is dialed in properly and no ice to sink the plane lol.

Good luck with the maiden. Hopefully all your lakes are free of ice at this point. Tough winter for your part of the country.

THe cam does have it's own battery which is good for recording about 45min.

Here we go for the GoPro on the CL-415:





With the CG as per manual, the pack must be place like such:



To give an idea how far back the pack is (not bad IMO)

It is not vibration that I find disgusting about videos shot with the GoPro,
but the wide-angle lens-induced apparent bending of the horizon. Except for that, the video quality is exceptional.

Well the bending horizon is bad in 720p but in 1080p is more then acceptable. You can always replace the lens by the way

Very good! I did not know that. Is the normal lens supplied with the camera, when bought, or is it something to be procured later? Or could the camera be bought with a normal lens only?
(A look at your first video, where your appliances are leaning over, is what I am talking about).

Unfortunately this is not supplied or can be buy with it. This is more of a ''hack'' then anything, I'll find the link and post it.

Look for Tarro's post. The lens is a Sunex DSL355A-650-F2.8

Did not perform the ''hack'' since I'm ok with how the GoPro performs but at least I know there is an option ''out there''

I'm a quad guy. We damp down vibration by doing both a static balance on the blades and then a dynamic attached to the motor.

The flight controller board on the Quad reports acceleration via a graph. So, you can run up 1 motor at a time while watching the X, Y and Z graphs for total ACC (or vibration).

You then work the prop around the motor at 45 degree increments looking for the least overall vibration.

If you had a mikrokopter flight board, you could do a test setup for each motor.

Also, since we hang our cameras, it is easier to damp vibration. The last thing we do is have the camera 'floating' in something like a cut up pool noodle.

hpiguy,
Doubt it, but you can e-mail em and they'll get back to you. Only problem I see with this foamy is that it probably cannot handle much choppy water. KMP use to sell a fiberglass CL-215, 80" ws, glow or electric. Should have picked one up. Nitroplanes sells a CL-415, 80" too, but it's been on backorder forever and a day.

This is a different model, with a 40.1 inch wingspan, while the Guan'Li that we have gotten from Hobbyking spans 54 inches.
