Independent tests prove lack of frequency hopping with XPS

[Kiwi]

Whooooooooooo,

Look at that, 2,4 Ghz and 35 Mhz running side by side. Now that has to be so solid its not funny.

That is some seriously well thought out stuff there, with the dual 2.4 and the redundant 35 (could be 72 as well) your really running three Rx's.

Phew, that is way cool technology right there.

Prof,

You seem to have some very good access to the information your posting and I wonder if this stuff is available on the street yet.

Those diagrams really show some key details that would otherwise be unknown. In the FASST receiver for example it appears the the two antenna system is switched. Does it switch to the strongest signal or does it switch constantly.

You have to admit either way that the competition is heating up and that only means good things. If the manufacturers can crack the FUTABA G3 data strings then there is no stopping them transmitting at 2048.

Its getting interesting. Take for an example the 12 channel Rx with true dual FHSS. If that Rx is priced lower than $400 it is in the game with the dual Rx users. However if it is similarly priced to the current 14 channel unit its a killer unit.

The thing I really get all warm and fuzzy over is the bi directional telemetry that some of these new FHSS systems can incorporate.

Rather than than the new guys meeting the playing field level I think they are raising the bar and that only means goodies for us end users.

Yee Haaaa

FASST selects an antenna during the time the preamble section of a data frame is received. See

Kiwi, as Frank posted the antenna is switched.

Some user in a german forum ("schaumwaffel" was his nick i guess and i guess it was rc-network.de) meassured the switching.

But I cant find the post.

ACT publishes a lot what the know about the outher manufacturers.

ACT has 35MHz receivers which are able to talk als Futaba and JR PCM formats.

The 2.4GHz stuff is not to get right now. No user posts about it anywhere.

I found a link to a lot of the product they make in an Italian web site.

Seems they really make a line of very top quality stuff and your right, the 2.4 Ghz equipment is not listed yet.

I will keep a watchful eye on the web site to see when they are hopeful of a release date but the stuff looks good.

I got in another good flight today (I know, NOT xps..... with fasst) at the Pensacola Naval Air Station, home of the Blue Angels! We were invited to come over and do demo flights!!!! Lots of fun!!!!

Nice videos

[Woketman]

Jon, why didn't you use XPS for those flights???

[jonkoppisch]

Thanks! I hate how bad youtube makes the videos look.. Let's see if these are better??


..... MMMMMMMMMMMmmmmm I don't know

Watch that FASST heat, we'd all hate to see you lose a plane on FASST

[jonkoppisch]

I'm watching the heat.... No worries!!!

Here's a vid of my 37.5% yak from today also. I'm using spektrum in it!!!!

I had my first lockout with FASST yesterday. Could have been a real disaster, but luckily nobody was hurt.

Flying in eastern Washington, and temps were in the mid 90's. About 4.5 inutes into a normal 8 minute flite with my E-Flite Electric Diamante, made a low pass, and just as I kicked the throtle and turned right to go around again, totally lost control, and the plane went banannas. It hung up rollled into the pits. The Landing gear absorbed most of the impact, and when they sheared, one of them cut a gash in a Carden Canopy. (Thats gonna cost me)

Have had not a problem here in Western Washington for close to 4 months, but temps are in the 70's or lower. First time flying in high heat and low humidity. Plane has about 50 flights on it. After it was all done, and thngs cooled down, everything works fine.

Futaba really needs to get a handle on this. It's got me really scared.

[50%plane]

Is that the Fat Albert behind the museum?

Looks like a fun event! I wish I could have been there.

Which fasst receier is this? I use the 7 channel in my bocat and have flown that in 114 degree (in the shade) heat without a problem. I don't leave the plane in the sun tho.
