Hi everyone.
Does anyone have any experience of this combination please? Setup I'm trying to sort out is an OS 105 HZR with the centre glide bearing with the spektrum backplate sensor in a Gaui NX7 on the vbar nitro gov.
On the bench the vcontrol shows it's detecting the crank going past, but not consistently every time I turn it. The square goes on and off a bit randomly, but it's getting something. When the engine starts it seems like the backplate sensor 'sees' the crank go past about twice for every revolution, so shows it at normal flight rpm when it's clearly much slower than that. It feels like the governor leaves it at what feels like about 1000rpm headspeed or less, even though the telemetry shows 1860. It's all over the place though chasing it's tail trying to manage the headspeed.
I found an old thread on helifreak which mentions the centre glide bearing not playing nicely with the backplate sensor, but I only found one mention of it in the whole heli universe when this must be a relatively common pairing I'd have thought! I can imagine that big chunk of solid metal doing something to the magnetic fields around there though, so no surprise if it's having an effect I guess??
I'm going to fit an old align magnet sensor on it, so i'm pretty sure this will be a solution, but it'd be good to know if it's just me, or a known issue.
Cheers,
Ben
