Hello flyers,
I recently lost a model out of straight and level flight with medium speed.
I first thought I had a signal problem or did a mistake while flying level. But, I was lucky and got the spare parts of the totally destroyed model from my local hobby store for free (they had the parts and could not sell them anymore - thanks again). So I was able to do some testing with the stock setup that led to the crash.
I was able to confirm that when quickly moving several rudders (elevator and aileron only) the receiver, in this case an Spektrum AR7350, cuts off after about 25 seconds and fails to initialize again afterwards. Of course, I did check all servos for free movement and also checked the servo wires. Obviously the BEC rating is not good enough but I could not confirm that with telemetry (voltage stays around 5V), so it must be short spikes leading to the cutoff. I will confirm that with some more measurements.
When adding a capacitor or using an external BEC everything works normal as far as I could test this until now.
Therefore I contacted the Horizon Hobby support. First they were quite interested in the info but then declared that this could not happen to one of their receivers and also stated that this wouldn't be a warranty case (however, I did not ask for replacement) as I had bought the receiver from second-hand in their opinion (which is not the case).
Despite I am totally unhappy about how Horizon treats feedback of their customers, I do not want to blame them (I was quite happy with their products in the last year) but wanted to share my experience with that receiver and that extra actions should be taken when using such a receiver in stock model setups.
Best regards
