Oh, I know they stretch. I said I'm not too worried, not that I'm not worried at all...and that's why it goes on the preflight list. -- Jay Maynard, K5ZC http://www.conmicro.com http://jmaynard.livejournal.com http://www.tronguy.net Fairmont, MN (FRM) (Yes, that's me!)

With the new 650 design could a chute be installed? Seems you would have to mount it up against the canopy, (doesn't seem very practical or attractive) or move it farther back on the turtle deck ( seems weight and balance would be an issue). I tend to think the chute is a bit of overkill as I trust the design but just considering the options. Mike

Yes, it does shift the CG back a bit, but it also protects the BRS from getting fouled with other personal baggage. One of the only other issues I'm wondering about is access for maintenance, but I'm sure they figured it out. When I get specific installation info from AMD, I'll try to post it here. Hopefully others will do the same.

From: "leinad" Roger, I see absolutely nothing wrong with what she has written. It falls in line exactly with what I was taught 10 years ago when in the ground schooling phase of pilot training. Avgas has always been made using stricter standards than mogas. I'm not in favor of requiring the gas i put in my car to be made with the same high (and costly) standards used in the production of aviation fuel. I think it's a good idea that these companies from time to time reminder pilots that if they choose to use mogas, they should no the risks.

It's time to pick a side and take 5 minutes to email. Our lives as people are good because someone didn't just say ok. Some took the time to make change and made it better for all of us. If we choose to sit on the sideline and just go along then we deserve what we get. I would implore all to take a minute and email these two people and any other fuel administrator in other companies. I will post on as many aviation websites as possible and I would you all to pick a side and stand up to be heard and maybe, just maybe we might effect change. I for one don't want to roll over.

Each includes a complete descriptive of the electronic ignition, fuel systems, cooling, mechanicals, installation variations and performance. Special articles on radiators installation and sizing, evaluating engine performance, re-drives, planetary, geared and belted are described for large and small engines. Considerably strong outlines on the EA81 and the EJ22 Subaru are provided to also compare them with air-cooled TC engines. Both are described as used with belted or direct drive props for 100 to 130 hp. The 3^rd Volume's illustrations drawings and photos are 1000-word quality, well worth the price for someone considering an alternative engine. The automotive- conversion can save you a whole lot on initial purchase, fuel and general maintenance. For those who would ask, its $42.00, ordered thru www.ContactMagazine.com or by phone at 1-559-584-3306.

When laying up fiberglass the instructions I've seen talk about using a paint brush to apply the resin. Does this mean I need one paint brush (to throw away) per layer of glass? I've seen instructions from one source that used only 3 layers of glass for the mold and 2 for the parts. Another used 14 layers for the mold and didn't say how many for the parts. For stabilizer tips does someone have a recommendation?

Assumed you've paste waxed the mold several times and buffed it. A brush is used to wet the mold with activated resin, then lay the pre-trimmed cloth in the mold, wet the cloth with more resin, apply the second layer of cloth and wet the inside until the cloth until both layers are wet. Stipple the bubbles from the cloth at each layer and allow only 20-minutes to get all this done. To save the brush, keep a jar of acetone handy to clean it and wipe it with a bunch of paper towels. Don't do this without throw-away latex gloves. I'm assuming your using a polyester resin , so do use a respirator.

From: "Roger Lee" Hi Dan, Most pilots are educated to the problems with 91 octane and ethanol. Many Mfgs. recommend that you use 91 over the 100LL because lead is more damaging to engines. I believe the EPA has a ruling that 100LL suppliers have to have a new fuel by 2010 because of the lead you breath and exhaust. ground based fuel has been in aviation use since the Wright Brother's flew. It is a huge part of the aviation community today. there are 280 aircraft at my field and over half can use 91 and they signed a petition saying so. There is a new fuel being tested. There is a new no lead 100 fuel being tested. -------- Roger Lee Tucson, Az.
