"Speed" tape?
At Reno, all the Formula One and Sport class racers had every single
non-aerodynamic gap covered with clear tape. Which got me to thinking, there are LOTS of non-aerodynamic gaps on my Pathfinder. The stuff looks like basic, clear packing tape. Anyone used this stuff? Is there any benefit at all, or is it one of those "over 200 mph" things, like the spoiler on my Mustang? -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

I had clear packing tape over it for a while until I could get it repaired. A very short while, as it turned out. Whatever they're using, it *isn't* clear packing tape.

It gets even more arcane than that. During a rebuild or major work, they'll
also tape up every opening and lightening hole INSIDE the aircraft as well. Air moving into the airplane will always find a way out, apparently, thereby causing drag. Since you can't close up every gap on the outside, they block up as many gaps inside thereby causing a dead end and no more drag.

Since gap taping is commonly done on gliders, I guess it is not just one of those "over 200 mph" things. I am not familar with the clear stuff though. Vaughn |

I believe you can access the IAC listserve archives from landings.com
A couple years ago this topic was discussed and discribed, including manufacturer and model number of the tape used.

Art Matteson of AMR&D uses tape for his gap seals. It's 3M Scotch #8672 one
inch wide polyurethane tape which you can buy for like $30 a roll. Of course for those of us with certified planes it would be "illegal" to put the stuff on without a 337 or STC. As far as I can tell it works about as well as aluminum gap seals it's just cheaper and easier to install. -Brian N33431 "john smith" wrote in message ...

I know it's illegal to put tape on control surfaces without an STC -- but what's the group-think on putting it on other aerodynamic problem areas? For example, on a gap between two clamshell halves of a wheel pant? Does putting speed tape on a non-structural member require an STC? -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

The high performance sailplanes use "turbulator tape" right on the wings.
Could also be used on powered aircraft. http://www.google.com/search?sourcei...urbulator+tape Karl "Jay Honeck" wrote in message newsZ%6d.84254$wV.12775@attbi_s54...

I used to fly gliders quite a bit and gap sealing cloth tape is commonly
used on the control surfaces. One day one of the club members landed in the Grob 2 place and practically kissed the ground when he got out. Part of the aileron gap sealing tape had started to peal up and it had such an adverse effect on the handling that the guy thought he was going to die. -- Regards, Mike http://mywebpage.netscape.com/amountainaero/fspic1.html "Jay Honeck" wrote in message news:5Uz6d.131331$MQ5.70054@attbi_s52...

The IA at Aircraft Mods & Repair told me that it does not require an STC. The part in question was the vertical stabilizer.
