400 foot range test? Is your TX antenna extended or collapsed? Is the RX antenna off the ground?

To give you a perspective: I range test mine with my TX antenna removed. I did a range test where the Corona would lock out at 200 feet with the plane on a table 3 feet in the air. That RX regularly does 2 miles.

At the risk of being a pain; I have a box of coronas 35, 72,40 mhz that i bought to select from to get a reasonable range. One day one or other looked good, the next day the same one was dangerous, and on different planes. They are totally un reliable for FPV.
It is not worth losing( or crashing) the fpv stuff economising on radio control. Buy Dragon Link or other long range so at least you can forget about one risk. You may want a bit more range one day, anyway.
I lost a plane and hundreds of $'s of equipment using a corona, because I lost rc signal.

My range test method is to put my transmitter standing vertical with the antenna fully extended in a second story window of my house, then walk around my neighborhood carrying the plane and watching the red light on the receiver. Because I have the half wave extension on, half of the antenna is horizontal along the fuselage, and half is hanging vertical off the tail.

I just ordered a new Corona last night, and I'm thinking maybe the half wave extension is more trouble than it's worth. I think I'll try it with the stock length for a little while first.

And foufly, I'm planning on getting one of those new ChainLinkDare UHF systems for Christmas, since that's the first one I've seen that looks even remotely affordable. I would love to have a more reliable RC control link that I didn't have to worry about all the time. After that one crash due to RC lockout, I am totally spooked by 72mhz.

I know somewhere I saw a link to a site for locating transmission towers in your area, but I can't find it again. Does anyone know? -- thanks, JOHN

Hi guys, I have a noob question.

I have a system from ReadyMadeRC ready to go. I also have an Easystar ready to go with the exception of one thing; the ESC and battery need to connect.

I am just days away from my first flight - this is so exciting!

The ESC is the brushless Easystar's, but for some strange reason it has no clips on it... So my quuestio is, where can I find the clips to solder onto the ESC? (to connect to the battery)

Here is a link. http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXPVF5

Connectors can be found almost anywhere. Just match up with what's on the battery.

Deans connectors are popular, widely available and easy to solder (noob solderer here, only been doing it for six months it's not hard). The main disadvantage I have found with them is that they can be difficult to disconnect.

Right but you cannot use Deans connectors on the ESC to the motor, can you? There are three wires on the motor.

Ok but there is some sort of outer covering that's not included. I'm not really an expert at soldering so this is a bit of a challenge for me...

I think the 'outer covering' you are referring to is shrink wrap - its insulation (to prevent shorts) and it shrinks in size when heated. You can get it at any electronics store or most hardware stores.

Do search on Youtube for soldering tips there are some tutorials. Its no magic after you see it.
