Title: Tulsa Contests pull test
Post by: Bob Reeves on June 27, 2009, 05:59:36 PM
Hi

Just to get the word out.. Anyone coming to Tulsa is requested to know how much any airplane they will fly in competition weighs in ounces. If you don't know when you get here we will have a digital scale set up in the club house for your use.

It will be the pilots responsibility to know what his airplane weighs and be able to tell the pit boss when he asks for the pull test.

One suggestion is to write the weight on the underside of the wing tip with a Sharpie.. It will wipe right off any finish with alcohol and always be with the airplane.

Thanks..
Bob Reeves

You wanna test that Sharpie idea on an old clunker...I am 100% certain that it won't completely "wipe right off" any finish. It's hard to get completely off aluminum. It will always show an image on Nylon, Delrin, UHMW, and probably Teflon. I'm sure it would show on any sort of paint. The "dry erase" marking pens should be fine, but maybe not durable enough, and often somebody will pick up an El Marko and totally ruin that new scoreboard that was intended to use with "dry erase" markers.  HB~> Steve

Sharpie comes right off my urethane finishes just fine.  Use them often when trimming.

Bob, be sure to report how the pull test rig works out.

put a small piece of trnasparnt tape on the wing where you want to write the weight.  Then you can use the Sharpie to your hearts' content.

Not sure how many stunt ships are made from aluminum, Nylon etc. but a Sharpie it will come off most common finishes. The clear tape idea is a good one or if you have a good memory you don't need to write it down.

We are doing the final assembly on all three machiines, although we will probably only need one or two for next weekends Trathalon/Mirror Meet all 3 will be ready just in case..

 Masking tape anywhere.  Write on the tape with anything you want.  Waaaaaaaaaaaaaay  too easy. n~

We write on our combat planes covered with mylar all the time; weights, rpms ,tip up/down, anything we need to kick our memory
back in the shop. The wide sharpie comes completely off with a couple of drops of fuel.

When doing final finish, why not make the weight part of a number on the plane.  I don't think anyone is going to complain if the plane is lighter than stated.   My P-39 kept bouncing between 60 & 65 ounces.  Told them to write down 65.  DOC Holliday
