First Time using the Data Logger (and a question about the antenna)

[Vahn]

I have a new JR XP9303 radio with the JR921 with one remote receiver in a 50cc Airwild Extra 260. I don't own a data logger, but a pilot at the field let me borrow his today.

My "A" antenna looks like it losing shielding. Where it is mounted in the plane, I am always accidentally bumping it when putting on my wings. I am considering sending it in.

Unfortunately, I could not get a picture of the "damage" with my camera. The camera can't get in close enough with the lenses I have. Their is a small part of the "crack" in the shielding where I believe I am looking at the actual antenna.

Here were the results of the data logger (with this "cracK") in the shielding.

A: 34
B: 02
Left reciever: 76.
Frames: 11

No holds and 5.0 volts (which is expected because the Smart-Fly Power Expander sends 5.0 to the reciever and 6.0 to the servos).

I believe the above numbers are good or even excellent based on my understand of the data logger, however I thought I would it toss it up here and get some input from those of you with more experience withe data logger.

Today, as a way to protect the antenna, I decided to put some glow fuel tubing around the base of the antennas. I've seen other people do this but I've never done it myself.

The tubing has a dab of hot glue to keep it on. The hot glue is not on the antenna itself, just the side of the receiver and the tiny support structures at the base of antenna.

I've attached a picture showing the installation.

Post summary:

1. I believe the above data logging numbers are "good" or even "excellent". Correct?
2. Do you see any problems with home made "antenna" supports.

Thank you for your time,

1) The numbers are pretty good yes. I ususally get < 10 on antennas and 0 to 3 frame losses in an 8 minute 3d/pattern flight, but our field is rather isolated from housing. But SOMETIMES the numbers really jump up I've seen over 100 on one antenna and 30 frame losses. But never enountered any loss of control and NEVER seen a single hold. With lots of other 2.4 TXs in the area they may go much higher than that and still not be a problem.

2) Supports look fine. But I noticed that you could mount your satelite in a slightly better position. Mount it so the antennaes are vertical, that way you have one antenna on all thrtee orthagonal axis. The way you have it mounted now the satelite and one of the antennaes on the main unit are both parallel so you are not getting as much diversity as you could. (The actual effect of moving it may not be measurable in the long run but why not get as much diversity as possible?)

I ended up sending in that particular receiver. The cracking in the shielding was getting worse. Thanks for the advise.

I will move around the satellite a bit and see what happens with the logger.
