Vbar Evo Gen 2 question

Hello,

How do I tell if an evo is Gen 2 and has the new sensor? What is the serial number where they changed?

Dave

Have the sensors actually been changed on the EVO units or are the ones being shipped post S/N 27001270 just modified with the hot glue gun fudge at the factory. The post on the Mikado site infers that, but dealers are saying the new units have new sensors....What is actually going on with these?

Hi David,

another short breakdown:

Units up to serial no. 27001270 require the hot-glue fix _if_ issues arise. See here.
They were manufactured/sold this way only until the end of May 2023.

Units from serial no. 27001270 were manufactured with the hot-glue fix already done.

Later (smooth transition, no exact serial no. available), units were manufactured with a different sensor which is not better or worse in flight performance than the one before, but which does no longer react adversely to particular frequencies (discourse see here).
Units with this sensors have been sold exclusively since October 2023 already.

So a simple set of if-thens can be:
. if < 27001270 check and glue if required—with that I mean, if it works without issues, there's no need for a quick fix.
. if < 27001270 and if there's the need to replace the housing, you can still apply the fix while you're at it.

. if > 27001270 nothing to worry, either they use cast sensors from the factory, or the later sensor version.
. if > 27001270 you want to or have to replace a case, you'll see if it's already glued—then carefully pry off the glue and re-glue with plenty of hot-liquid glue, make sure it really engulfs the sensors, put back together hot.

. if you want to know more about your unit > 27001270, feel free to ask or e-mail to service (at) mikado-heli (dot) de.

The hot-glue fix is perceived as a shirt-sleeved (I have heard worse ...) solution by 'Experts', but it's a technically perfectly sound and usual approach, to cast electronics, to engulf them with 'something' (in this case hot-glue, which some perceive as craft glue, cheap, not worthy), to protect them from 'something'.
The intended and achieved effect is to make the sensors deaf (in a true sense, we are talking audible frequencies carried over over the air) to certain frequencies. You could also use silicone glue (same effect, but has a less cheapish reputation, maybe just because it has a big word in it), and not as simple to apply (quite runny), or you could use resin (e.g. Epoxy), which is also less simple to apply, and which is more or less permanent and makes a simple replacement of the case cumbersome if not impossible.

Kind regards
