Knots 2U gap seals
I am thinking of fitting K2U gap seals on my Archer.
Are they worth the cost ? Thanks for all input Jim |

I got about 100fpm better climb rate on my Six and better control at low speeds. It no longer quits flying in the flare. I didn't really notice any speed gain, which means any speed gain was less than 2 or 3 knots. I installed the flap, aileron and stabilator gap seals. For me, I was mainly interested in improving the climb, and I am happy with the results. |

Although my opinion is second hand, since the flap, aileron and stabilator gap seals were already on my Pathfinder when I bought it. However, the guy who installed them reported the same results. BTW: If you're looking for extra speed, nothing (on a fixed-gear Cherokee) beats the "Fancy Pants" mod. -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" |

wrote: I am thinking of fitting K2U gap seals on my Archer. Are they worth the cost ? Aside from low-speed handling, there might be some small fuel efficiency gain. If you fly the same RPM setting, you fly any faster, but you might use less fuel. -- Bob Noel Looking for a sig the lawyers will hate |

No... (IMHO)
Mattisons' Gap seals do the same, fraction of the price, and don't freeze. Dave On Sat, 03 Feb 2007 17:30:15 GMT, "JAMES VOYTEK" wrote: I am thinking of fitting K2U gap seals on my Archer. Are they worth the cost ? Thanks for all input Jim |

Mattisons' Gap seals do the same, fraction of the price, and don't
freeze. That's a good option. Art Mattson's gap seals are just plain-old 3M tape, and (from what I've heard) they work great. And, when they eventually wear out and you have to reinstall them, you just buy another roll of tape.

Knots 2U gap seals
Hi Jay!
Yeh, I asked him about that... (how long they would last) Two possibilities.. Kept outside? probably 10 years... Hangared, ? - " how old are you?" "..59 ". - he said "I should not worry about it"... He sells enough (replacement) tape for the 3 surfaces for 60 bucks... The tape is almost invisible.. NOBODY notices it until I point it out to them. And that is on new pure white Imron...... On dark colours, it's gone... Seriously tho.... a local 140 here has the K2U seals. They work fine. They took off and climbed..and the ailerons "froze". He was afraid to try breaking them free in case they stuck again at some position other than neutral. He "ruddered" it back to a safe landing, winds were calm. If it had been X-wind or gusty? He said the did not want to think about that... Dave - On 3 Feb 2007 19:54:19 -0800, "Jay Honeck" wrote: Mattisons' Gap seals do the same, fraction of the price, and don't freeze.

Wrenches? What are the rules on this one? It ain't "mounted" and it surely is not permanent. It modifies nothing. Mike |
