Thoughts? Has anyone else gotten range like this? Any idea what the "SAW" filter does in laymen s terms? Plain basic English would be fine :) Is it a huge improvment? Is that was makes 55km possible for this guy? I'm amazed at the range when it's hard enough to keep a signal at a mile lol.... Thanks for any help!!!

no saw filter makes you go 55km, the quality of the instalation, how far things can be seperated and insulated makes other things work further

this vid your showing wasn't even on an aircraft was it? that means nothing

It means nothing? That was still 55km whether it's on a plane or not, that's amazing. So the "upgraded SAW" filter thing is the removing of the SAW filter?

if theres no motor or esc making RF, it'll go further than that, easily. I've seem planes fly over 100km one way with better reception.

Upgrading a saw filter is getting a higher performace component and solder swap it out

sorry, but what's the point of flying a distance of 55 km with a Multirotor.....??? With a Zephyr it's a different story.

At the speed of 50 km/H it takes you 1 hour to go there and another hour to come back....at average filght times of 8~15 min....

And to know that with a Helical/Skew Planar Wheel and a good antenna tracker I will get longer Video range than I have line of sight or enough juice in my LiPo's I don't have to walk 55 km :tennis:

I'm not sure where you got that "point" from as the point is the range of the signal being transmitted. What you put that transmitter on is another story. If you can fly 55km, you can probably do 10km behind trees too. It's not about going 55km, it's about having the best quality signal and not losing video feed. The better the feed, the better you'll fly because you can see. Long range things like wings and gliders need a setup like this even if your goal is 5km. Overbuilding, to a point, is better than losing your entire model and starting over.

I use this http://www.dpcav.com/xcart/Adjustable-Voltage-Regulator-1-35V-Step-Down.html for my 12V power bus and this for the filter http://www.dpcav.com/xcart/Power-Supply-Filter-L-C-Type.html and they work very, very well and make a noticeable difference. The voltage regulator is nice because you are always giving your video tranmitter maximum voltage versus a battery who's voltage dies as the capacity is drained. The L-C filter removes the wavy lines and noise from the dirty power and cleans it up some. I highly recomment a setup like this although I would get a differnt L-C filter than the one I listed because it was EXTREMELY hard to solder that close together.

I find it very hard to conceive that it will be possible to find a battery that will hold the multirotor running for long enough to cover that distance.
