Lock-out On My Delta-G V2

Dear all, I just came across a problem with lock-outs while flying. First of all, lock-outs happen when you fly in an area with something running on your radio's channel (ex. wifi routers). In my case, I like to fly on 2.4ghz. The only problem with this is that wifi routers also run on 2.4ghz. There were also around 60 dorms next to where I was flying, each of which had a router. My reciever was trying to listen to my transmitter, but the wifi convergements from the bunks were also screaming at the reciever. While exploring the air, I found some definate wifi spots, none of which really effected my flying for more than a second. But soon enough, I found the biggest wifi spot in the area. I had no control over the aircraft, for it was stuck in a roll falling toward the ground. I was never able to recover, and it hit the ground hard. Luckily enough, the magic of EPP foam kicked in, and my combat wing was unscathed. For all you people who fly on 2.4ghz, please make sure you are in an area that does not have rediculous wifi spots, or else your plane could possibly crash. My friend Tomoki wrecked his beautiful motor glider from the same problem, at the same place, flying the same frequency. Remember, if your plane locks out, than land immediately. It's annoying to lose a plane from a lock-out. As always, happy flying!

Thanks,

Giles Beebe

What transmitter/receiver combo were you using?

I was using a Dx6i with an orange rx R410. The R410 is made to be light, so it doesn't have any satellites. I think with a receiver with satellites would fair much better, but many people fly with skimpy receivers like this. Also my friend's plane suffered the same problem with a nice spectrum reciever.

GB-air, It isn't the fact it is a skimpy receiver. It is that the Orange rx R410 uses DSM2, DSM2 Picks 2 fixed 2.4GHz Channels when you turn the radio on and jumps between them. In a heavy populated 2.4GHz area this can be bad. (http://en.wikipedia.org/wiki/Radio-controlled_helicopter#Spread_spectrum) The DSMX protocol is much better it uses a FHSS protocol (Frequency-hopping spread spectrum) it basically changes channels several times a second to minimize the possibility of a lock out.(http://www.spektrumrc.com/Technology/DSMX.aspx) (http://en.wikipedia.org/wiki/Frequency-hopping_spread_spectrum) I personally own a few Orange RX DSM2 receivers. I don't have any issues at the park I fly at. But at my Flying field a have had nothing but problems with them. (lost 2 aircraft due to lockout at the field) Once I switched to a DSMX receiver I have had no issues.
As for your comment about Satellite receiver antenna. There is no reason to put them on a FliteTest Full foam board aircraft. There is really nothing in these aircraft to cause radio dead zones which is what a satellite receiver antenna is meant to help with. Aircraft with a lot of carbon fiber or big motors are really the only place they need to be used.
