sorry,im terrible at explaining
You can do it that way, but aditionally also use a drink straw below the wing to also stiffen that part. Since the straw can easily bend back upon landing all you have to do is straigthen it bevor launch.

The turnstyle recommended by Loco is great, but you must be aware that having the tx antenna horizontal also means to have a null to the left and right of your position. This might form a problem with FPV as you are not always fully aware how the plane is positioned in relation to your location.

In your back is no problem. The null is to the left and right of you if your tx antenna is horizontal (asuming paralell to your tx as it most likely would have to be based on how RL is constructed). I attached a little "hack" kind of a drawing to ilustrate what I mean.

I just ordered a RangeLink with two receivers too. From what I understand, the advanced binding reseeds the frequency hopping table. All units ship with a standard frequency hopping table and advanced binding re-initializes the table with new unique random values. The reason to do this is so that you can fly with a friend who also has a RangeLink and they won't bother each other.

Sid, correct me if I'm wrong.

Hi guys Ive got 2 Z2, One of them I get 20 meters on micro range test and the other I only get about 10 meters.

The one that I only get 10 meters on, How far range would that be?

Is anyone using RL with a Turnigy 9X thats powered by 2 X 18650 li-ion batteries? Any issues with usage around the low end of the recommended 7-13VDC input voltage?

I use it with a 9x, but I use one of those dedicated tx 3s lipos available at HK and other places to power it... No problems whatsoever as obvioiusely the voltage there never drops that low.

Ditto... using Turnigy 9x with dedicated 3s 2650mAh Tx battery pack. No issues with low voltage.

I just received my RangeLink system with TX and two receivers.

Last night I got the TX attached to my old Hitec Eclipse and it works great. Installed an RX in my EasyStar and it was plug and play and all works well on the bench. RSSI works perfect with Skylark Tiny OSD.

I did notice that the RangeLink TX does interfere with my cheap Sunsky 1280 MHz video RX. This is a documented issue with any UHF system. I guess it's time to by two Lawmate video receivers.

Next is to range test and then maiden!

Shipping was fast and Sid delivered as advertised. It looks to be a very nice product.

I'll report back after my first flight.
