Default RE: Showtime Flutter

Hi Everyone,

I witnessed the events as described by kenandannie. Yes, I was there. The Showtime was only on it's 4th or 5th flight and was being flown very conservatively. I really would like to be there when the wings are inspected. I understand that they have been sent back to H-9.

I am a quality engineer and I did a search in Mike's Forum under 'Flutter'. I understand Mike's knowledge and point of view on flutter and using the correct servo set up, etc. But there was no flutter in this case, the wing simply came apart inside and began to flap severly exactly as BR289 and Spoiler described in their posts. I believe that BR289, Spoiler and Kenandannie have presented enough information to warrant a throrough review of the building process. It is time to take a look at the wing building location. Are there control numbers or production runs stamped in the wings? You need to find a clean point working backwards to the time the wings in question were built. This should have been standard practice after Spoiler brought up the problem in July, 2005. If I let product go down the building process (knowing the information I have been provided) without finding reviewing the building process and creating a clean point, would be gross negligence and I probably wouldn't have a job either.

Ken took his ST up afterwards and duplicated the same manuevers over and over - in fact he put the ST through a lot tougher testing and his stood up well and his plane has more flights on it.

I have been saving my hard earned money to purchase a ShowTime to fly this Spring. I believe it is a great airplane. I have read all of the reviews and feedback that I could find. No doublt about it - it is a great flying airplane. But now, I will not purchase one until I am certain that the wings are being built properly - I can't take the chance on spending that kind of money. I don't want to put all my expensive equipment in a plane that is prone to failure.

Since I am ready to purchase I will have to go with Quique's Yak. I have also heard great things about this plane.
