Re: Partial motors in low ceiling scrubbing

I replied to this old post by Mark yesterday, but it doesn't seemed to have shown up. So here it goes again ....

I do partial motor testing for scrubbable ceilings by observing when the model descends to the proportionate height. For example, say I'm in a 40-foot scrubbable gym and using 1/4 motor for testing, and the intended full motor flight is in the same 40-foot scrubbable ceiling. For the 1/4 motor flight, I time it until it descends 1/4 of the way from the ceiling, in this case, when the model descends 10 feet to a height of 30 feet.

I did this with my F1L in Colorado Springs, which is a 37' auditorium with a smooth scrubbable ceiling. For 1/4 motor tests, I timed the flight until the model drops about 9' from the ceiling. The 1/4 motor tests were about 3 minutes, and my full flight was just over 12 minutes.

Hope this helps.
