I’ve had a bit of bad luck with the receivers that I have purchased this year, so I would be interested to see what success rate other people are having. Possibly I need to buy some better quality receivers, or was it just bad luck?
Of the 5 receivers purchased, 3 where either DOA or failed the pre-flight test.
1. Hitec Optima 7. Used successfully for about 2 hours. The rx has never been crashed. Then one day I did the preflight checks and the servo response was delayed/jerky and occasionally went into failsafe. Hasn’t worked properly since.
2. Hitec Optima 7. No problems except that the servos jump quite a bit at power up (3A SBEC, not using SPC)
3. Corona 4ch 35MHz single conv crystal based. Works well and very cheap. So I decided to buy another…
4. Corona 4ch 35MHz single conv crystal based. Very poor range (~1m with tx antenna extended)
5. Corona 4ch 35MHz single conv crystal based. Thought receiver 4 above was unlucky, so bought this one . Jerky/delayed servo operation (particularly ch4 ). Unusable.
Anyway, I would be very interested to hear what rx failure rates other people are having (excluding interference, crystal, power supply, or crash damage issues). The poll questions are not scientifically constructed, but might be interesting anyway.
