mate bought rtf pz corsair in oct '08. dx5e, ar500, good entry level warbird. in its life so far it has ventured no further than that fuse. i purchased a dx5e tx/rx package in oct '09. my rx has seen 3 birds and a losi micro rock crawler, which i learned the hardway about current and killed an esc and a battery pack by running 2x13 kg mg standard servos through esc(1.5 amp). it currently resides in an st model elec. fox glider. not a glitch. only problem i have had is low voltage tx and micro stuff, mainly ar6400. which figures because the bricks only run at 4.2 volts max single cell lipo and need stronger single strength (from 1 green light left and below on tx... be warned, i've dropped at this capacity and less! no red light and.....thmp).
apart form micro, no complaints. back to my mate......and no real issues until end of april '10...recently infact, at vic park adelaide. had real trouble binding his tx to rx, had to bind his to tx to my rx and my tx to his rx then his tx to his rx for it to bind?!?!?!?!?!?!? wtf! should have sniffed something there............but like trusting lambs to commercial slaughter..... we flew.
now, couple of minutes in corsair locks in a direction, cant remember off top of head, from 20m, 3 death spirals, about 4-5 seconds of no signal and 1.5m off the ground......signal. my mate landed promptly then soiled
. i continued to fly on same system through same areas unaffected.
back home, we thoroughly tested power sources and tx/rx combos to this conclusion....
both our dx5e transmitters worked well with my receiver, on/off at tx = <2sec for first 3 switches in a row.
my tx with his rx= intermitent, 30% within 2 sec, 70% between 2 and 5 seconds.
his setup up to 10 plus seconds!! i guess you can get away with that at 1000ft, not.
so we decide to test our lhs and spektrum customer support. we hand it in and they send it off. went in the other day and happened to get on the subject and reported that testing found a perfectly sound receiver.
now i know i haven't had problems....but after what i had witnessed.........makes me nervous about upgrading within spektrum.
if it wasn't for their micro series of rx/esc/servo bricks i probably wouldn't have gone spektrum.
but still, it's been solid for me
