Mkmkmk13,
That's funny because (although I haven't been flying much lately) the voodoo does the same thing to me. When I am unplugging the wires after flight I look like I have Parkinsons desease. Even the P5 is "peaceful" to fly when you look at the speed/size ratio.

Last Sunday all I wanted it 's go to bed after rough Saturday night
But I could not miss a great sunny Sunday and went to the field with my
beloved VooDoo.
It was a best treatment from hangover I have ever had

Guys got a voodoo on the way, had a dynamic 400 which was just not fast enough. At the moment I am going to put a mega 16/15/3 in it and see how it flies. What is the best setup (For speed) on this motor in terms of prop? How fast would that be?

Is 4s worth the extra effort over 3s? Look forward to hearing from you all soon.

This is my only plane that I would not fly with a hangover

LOL!! And you thought the 16/15/3 or 3w (if I am right) was too slow for you

The 2w20 kicks a$$ even harder!

No. Any deflection that stressed the materials that far would leave visible damage. The actual fatigue life of carbon/glass composite parts is very high - thousands of deflections at least.

Can you explain why competition f5d racers and hotliners can be bought when they are just one season old for a bargain?

When I purshased my f5d Nemesis I picked the plane up by Ruud Zandvliet himself (the manufacturor and designer) and he told me these planes are likely to break or flutter in the 2nd season due to the 60-70G turns when in competition. These competition planes are build to be lighter as stock version . A carbon wing/kevlar fuse does not live forever. This has nothing to do with fasion. The Voodoo appears to be fragile compared to an f5d plane and I would not buy any 2nd hand if I know the owner stresses the plane on a regular base.

For not competition planes I'd buy a new wing every 3 years if I fly it frequently.

An other thing is that even in a carbon wing there is balsa imbedded, even in the voodoo. The Balsa cannot handle the stresses forever which causes the wrinkles on top of the wing. This is a sign to sell the plane ASAP

Erik I really don't know what you are arguing about. My answer was to dessertracer who as worried that the stresses encountered while the model was being shipped to him would permanently damage the airframe due to fatigue. My answer was not to worry because the strains encountered were probably relatively minor (because there were no visible marks on the airframe from being squished), and the number of deflections in the delivery would be low. Just how many times can a delivery person mistreat a package?

I never said that flying a model for a season didn't affect it, maybe that could apply thousands of deflections (especially in turbulent windy conditions), and weaken the structure. However full size glass gliders have been flying for many decades, and I am not aware of any limitations routinely applied after X thousand of flying hours.

Neil.

The full size gliders may live long, but the aerobatic planes only last 200 flights.


grtz! Erik

Full size aerobats? Really? Can you provide some evidence of this?

Does anyone use outboard servos? (sorry, haven't taken the time to read the entire thread)

I was wanting to do that to save space in the fuse--looks like fitting a 4s could be feasible w/o fuse servos. (I'm not trying to set any kind of speed record, but with an outrunner kv of 3300 or so you can go back and forth between 3s and 4s)

Would HS45 HB's be sufficient in torque?
