Here are the minutes of the 2008-02-12 meeting.
* Tom opened.
* Indoor plans. Salt Palace won't work.
* Promoting sport.
* New meeting place in the works, parking stinks @ Spring Meadows. Under discussion: Taylorsville city hall (police dep't). Salt Lake City/County complex like the Silent Flyers (IMSF)? Just parking issues here, really.
* Don't bypass the combination lock on the yellow gate. Horse owner got locked out and Tom had to drive out to unlock our lock. We do that too many more times, we lose the field.
* Close the green gate behind you due to livestock.
* Web site calendar partially updated.
* February fun fly is RPRCC.
* March event: Climb & Glide. Last year Scott won with a Jett .46. 30 seconds climb, then shut off.
* Steve Wilson picked up two 58-watt solar systems; we're still in need of marine batteries to be charged by the system, and a bench and power panels. This will be really nice when it's finished! Volunteers to provide marine batteries already, we just need to plan the structure and power layouts and set up a workday.
* Pat from Some Dude's spoke. It's easy to buy stuff online, but Pat is trying to grow the local business. Monthly special for club members only, cash or checks only, many drop-ship options.
* Marv built the T-28 electric, but charging the battery didn't seem to work. The replacement one wasn't much better, on spool-up the speed control melted because the motor fried. Took it back another time, local dealer helped him out. Learned a bit about electronics, and learned a bit about hobby shops: Marv bought it from Some Dudes, and he treated them right.
--BREAK--
* Wade showed us how to lay up fibreglass. Wade uses epoxy resin, but use a scale to three places in order to make sure your ratios are correct. Guesstimating won't work. PTM&W epoxy works nicely. Wade can get you the numbers. The main reason to lay up fiberglass is if you are going to produce a lot of a particular part, not necessarily for detail or weight.
-- First you carve your part out of pink foam. Get the finish perfect, because your fiberglass part will exactly mirror the finish of this part. Prime the part and dd release agent (wax, like car wax but no silicone, then water-based release agent).
-- Next you lay up fiberglass over and over on the part. Mix about 2 ounces or so at a time.
-- To make the mold, what you use is some high temperature tooling resin. You're going to put it into your hot box, so you need it to withstand the heat.
-- 8-10 layers of epoxy can form the mold. 12-20 minutes pot time. Brush the epoxy on first to cool it, then lay your glass on.
-- Drill holes after laying it up to make sure your alignment will work.
-- Wax/PBA the inside of the mold.
-- fiberglass options: 2, 4, 6, 8 ounce. West systems carries 6 ounces. Graphite, carbon, kevlar, whatever.
-- 3/4 ounce cloth is nice for basic airplane finish with little weight. 8 ounce cloth + 8 ounces of resin is a pound to your airplane, so weight matters.
-- Dissolving the foam out is a really painful method that leaves lots of crap.
-- Use 2 ounce on the outside layer, and a 4 or a 6 behind it for bulk.
-- Layup: Just lay it inside half the mold. Use something slender to pry it off. A little Mylar works well..
-- Normally you don't take half out at a time. You lay up the two halves, then seal them together, then pry the part out. Just lay down some resin inside the mold, then tap in the 2 oz then 4 oz on top of it.
-- Wait for it to partially cure, then cut off the extra stuff. Don't wait for it to cure fully, or you're using a Dremel tool to cut it off!
-- Lay a little bit of resin between the two parts, then lay a little 1" piece of fiberglass to join the sides. You can also mix some cake-frosting consistency stuff (Kavosil) looks like powdered sugar, microballoons will also work, and then just lay them together for really thin parts.
It's not an easy thing to do, but if you have the interest, Wade will be glad to help you out.
* Warbird event & Fun Fly in August, Wade & Pat willing to CD it. We need more advertising, more time for sponsors, etc. Need to get commitment from SLC regarding the modelport still being available. Tom will call on the City Council to make sure it's available in August. Salt Lake City attorney, Paul Burke, is a good resource. Lehi possible as an alternate, has two fields now. Get it into the AMA magazine, getting it sanctioned this year. Doug's a CD, and will work on getting expo and electric fly-in sanctioned. You're welcome to meet with Pat & Wade at the store to volunteer to help in planning.
* Ron Mendehl is a good contact for going fast! Matt asked about running pylon, and the general consensus was to either run in a different salt pan, or use spare time and chat with other flyers to make sure running pylon is OK at the time with them. Hard hats required for competition, recommended for practice.
* Are our interests being preserved in regards to the modelport? Someone needs to do a FOIA on the contract and stand up for setting up a new field.
* Old dump possible site? Maybe smell funny. Way on the west.
* We may want to form a committee to represent our interests. Matt volunteered for the field committee. Steve Wilson volunteered. Doug is glad to help. Ron Christiansen did some great legwork, according to Evan.
* Doug showed off his biplane. E-Flite Pitts 12. E-Flite 25 for power, 40A switching ESC. All laser-cut, nicely built.
Doug Dorton won the show-and-tell prize, Matt Barnson won the GWST6 airplane.
