Hi Mike,

Where did you find it for $700? I am assuming we are talking about the ADS600-EXP. On the Navworx site the unit itself is $1149.00. Then you have to add at a minimum the TransMonSPE option unless you already happen to have one of the few new transponders that will interface with the ADS-B unit. With that, the GPS and UAT antennas the setup prices out at more than $1500.

I have been watching this for a while as I have one experimental and one certificated plane to equip. It looks like I will be doing something different for each as the experimental may have lower cost options. I am waiting for a couple more years to see what happens. I am curious to see if Google and others will follow through on their claims of bringing a less expensive stand alone option to market.

That is the winner at $700.  Uses your existing (old) transponder, weighs a pound.  Looks like you need to install a GPS antenna and a transponder type antenna.   It outputs a wifi signal to your tablet to display the traffic.  I use an Android tablet with AVARE software.  AVARE is free Android software for navigation, flight planning, has airport facility directories, IFR charts...  Really, it's free but most people make a donation to the developers.  

Now will it drop in price as we approach 2020?  I'm going to hold out a bit.  Thanks Jerry for the info.

Thanks to you Guys,

I knew you had some ADS-B answers!

I am old school and have a mounted Garmin 296 (can switch to a 796 if necessary) both of which I think are WAAS capable. Sam Kittle suggested I call Garmin and discuss the possibilities with them. I will let you all know what they say.

P.S. I uploaded an interesting pix of N46JP ( to photos) after arriving back in the Bay Area last Sunday evening. Take a look. It's a little different perspective and might be suitable for desktop background if some one was so inclined. The dream is still alive! Don't tell Bruce though, he may want to sell that tin can and get back in  glass.

Jay, 

I work at 3M with the qualification of Arospace adhesives to different OEMs. One of the main points on the qualification of a new adhesive is the mechanicals (in different temperatures if necessary), if you have a Technical Data Sheet of the original adhesive I can search for a compatible adhesive. I want believe that one of the main factors will be overlap shear for fiberglass bonding.

Re: Recommended Epoxy System?

One error listed the Tg (delinking temp) of EZ Poxy as being 155 degrees. That is the ultimate Tg, not the initial Tg which is less than 40 degrees above the temperature at which the epoxy cured. Post curing raises the Tg faster than time, which takes months of exposure to elevated temps. That is why white paint is used. It only raises the underlying epoxy 10 degrees in sunlight.

Also, check out Seattle Avionics, they have ADSB in/out for $1499 and you get Fly-Q for a year for free. I’ve been using Seattle Avionics products for many years and I have almost no complaints ( was not real thrilled with their SkyPad II). Fly-Q has bee a great product, and like Foreflight, they are always upgrading the APP.

Larry,

 

Post cures need to be controlled events. It is very difficult to follow a post cure schedule and keep the whole structure even temperature. That is why I use Aeropoxy and get a Tg over 150F. No need to post cure and take a chance of ruining your structure.

 

Your method will leave the structure with areas that the Tg increased and areas where it did not increase. Maybe if you build a giant rotating fixture and spin it the sun can heat the whole thing.

Re: Recommended Epoxy System?

Brad Walker
 

Every epoxy has a glass transition temperature (Tg) range that varies. If you want your epoxy to be at the top of that range then you will need to do some post curing. But, the top of the range can not be extended just because you did a post cure per se. The epoxies used in most amateur built aircraft have a "low" Tg, i.e. something in the range of 60C-80C range.

If you want/need a higher Tg then you probably need to go to a different epoxy that is more specialized. Here are some epoxies from Huntsman Chemical that I've been looking at.

http://www.huntsman.com/advanced_materials/Media%20Library/global/files/US%20Composites%20Selector%20Guide%20for%20Wet%20Lay%20Up_RTM_Infusion_Filament%20Winding_Pultrusion_Araldite_RenLam_Aradur.pdf

And if you want to know a good explanation of Tg then this PDF should help.

Re: Recommended Epoxy System?

One Sky Dog
 

Jay,
Like Rob says definite limit. Room temp systems are all over the map depending what they are formulated for. Epoxy designed for boats and wood is mostly to encapsulate the wood and keep moisture out to prevent rot. Happens it is pretty good glue for wood too.

Formulations like Ez-Poxy (basically renamed Saf-T-Poxy) and Aeropoxy are designed for aerospace and airplanes and have higher Tg's but 190 something F is all you will get. I think Aeropoxy will be over 155 F with a 7 day 75 F cure.

Like Rob say's.

Regards,

Charlie

Re: Recommended Epoxy System?

kingdws@...
 

Its diminishing returns. The most is gained by the first tempering, and there is a slight amount gained for every heat cycle. Eventually the crystali e structure is aligned almost entirely. So in other words you might get 98% on the first, then an additional 0.6 on the next. And 0.1 and less each one after.
