    Hi All' I plan on reducing the load on the tie down by adding about 80 lbs in the baggage compartment. I also was thinking of 40 lbs on either side of the vertical stabilizer. Thoughts?

    I use bags of water softener salt to weight the tail and other things. The plastic 40# bags are tough, and convenient. Find the brand with built in handles. Use some care to make sure they don't slide off when the angle changes, and of course make sure they pick up the structure of the stab. You'll be fine. They belt in to the seats pretty well too when you do gross weight testing. We would duct tape several together to make them body-size. Then, make REALLY sure it's well secured so that Sal doesn't slump forward on the controls... --Dave On Sun, Mar 15, 2015 at 7:23 AM, Craig Rufi <craigr60@gmail.com> wrote: > Hi All' > I plan on reducing the load on the tie down by adding about 80 lbs in the > baggage compartment.

    My intuition tells me that this unit resides in the same squishy area as IFR navigation equipment for EAB aircraft, and my guess is that if you put one of these in your EAB aircraft, that there will be no squealing from the powers that be. After all we are not exactly (for the most part) flying high performance turbine equipment. Modern GPS - even in my I-Pad updates way faster than the FAA's antiquated mode C - transponder system. Kudos to these guys for getting this on the shelf for us to meet the 2020 deadline. :D -------- See you OSH '15 Q/B - flying 5 yrs.

    I would skip it on the stabilizer. Too much chance of bending thin skins an d it would be easier for it to fall off and lose that weight. Just throw it in the baggage area and you'll be fine.

    Subject: Re: Has Low cost ADS-B arrived?
    There are GPS performance specs as to accuracy as to location, heading and ground speed, frequency of update, etc. Your Ipad is very unlikely to meet those specs. Most decent WAAS GPS modules today receive at least 12 satellites simultaneously, apply WAAS correction, and output updates 5 times per second. No relationship to radar and transponders which update once per 6 seconds at best. The guts of a GPS that does the above cost under $50 in quantity. Apple chose a different route, using cell phone towers and a cheap non-WAAS GPS to derive position. I don't know if they improved the GPS as newer models came out. They still use cell phone tower locations to massage the location, something the FAA would not accept.

The newer models (I believe iPad 2 was the first) all use WAAS GPS chipsets and do not require cell towers for assistance. -Dj -- Dj Merrill - N1JOV - EAA Chapter 87 Sportsman 2+2 Builder #7118 N421DJ - http://deej.net/sportsman/ Glastar Flyer N866RH - http://deej.net/glastar/

    Thanks Dave, When you say,"pick up the structure of the stabilizer" I'm taking that to mean close to the vertical stabilizer, and balanced on both sides. There the ribs are closer together and a stronger surface for the bags to rest on. My pool also needs a little more salt too:-)) On Sun, Mar 15, 2015 at 7:57 AM, David Saylor <saylor.dave@gmail.com> wrote: > I use bags of water softener salt to weight the tail and other things. > The plastic 40# bags are tough, and convenient.

    Kind of. I mean make sure you have contact with the spars and as many ribs as possible.

    Subject: Re: How to lift the nose wheel without an engine hoist
    Be very careful with bags of salt. They are typically abused in their delivery to retail store shelves, and frequently have small tears that let salt out. Extremely corrosive to your aircraft. It doesn't take but a bit of powder out of one of those bags. And they are heavy enough it doesn't take much abrasion to put a small, barely noticeable hole in a bag. I've seen corrosion in car trunks and pickup beds from that. I agree with Tim, either put it all in baggage compartment, or put some plywood or similar on stabilizer to spread load and prevent damage there. Sand bags or collapsible water jugs are preferable.

After all we are not exactly (for the most part) flying high performance turbine equipment. Modern GPS - even in my I-Pad updates way faster than the FAA's antiquated mode C - transponder system. Kudos to these guys for getting this on the shelf for us to meet the 2020 deadline. :D You'll get no argument from me that the specs are way too stringent. But remember the FAA doesn't care about us - they do care about an airliner hitting us. So IMHO there will be no relaxation on the specs.(IF they did relax them, now, the companies that already are in the market with TSO'd boxes would cry foul - and they'd have a point). And btw, there's nothing "squishy" about IFR navigation equipment. Your operating limitations require you to follow the same 91.205 rules as the normally certified aircraft. I applaud Navworks for trying to bring the cost down, and in fact this is a very competitive price even without a position source. But I won't believe "ready for 2020" until I see someone say in writing that the built in gps meets 91.227. -------- Bob Turner RV-10 QB Read this topic online here: http://forums.matronics.com/viewtopic.php?p=439419#439419

    That is a good question and I don't know the answer. I know that the goal is "no slop" and that you are limited to a maximum of three washers. It seems possible that the more pre-load, the more the donuts compress over time, but I'm not sure. I would bet that compression memory is a combination of both time and pressure with a little pressure over a long time having the same effect as high pressure for short bursts. It also seems to me that the act of compression itself is what absorbs energy and therefore a higher pre-compression could mean less potential energy absorption capability in the system. I have heard that they are expensive to replace.

    I just installed a set this week. So far I am happy. They aren't Rosen's but they aren't Rosen's price either. -------- Myron Nelson Mesa, AZ Flew May 10 2014 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=439425#439425
