As far as the Mezon ESC,

Here's what Hacker says:


Information from Hacker Motor Service
Dear customers, there are still failures and fires of Master MEZON 90, Mezon 90 lite
and Mezon 95 opto controllers when used in F3A models.
The reason is as follows: These controls are all too small for use in an F3A model!
Reason:
1. Mezon controllers are constructed differently than e.g. Master SPIN controller.
Only a few power transistors are used in the MEZON's (only 6 in the MEZON 90!),
which have to carry the entire current load.
With the SPIN 99, for example, many smaller MosFets are installed, which are distributed
over a larger area on the heat sink.
The heat dissipation is thus much better, the controller has better "taker qualities".
A MEZON 90 is therefore not comparable to a SPIN 99.
2. The phase currents are significantly higher under load than the indicated current in the controller.
A regulator should therefore always be designed 20% -30% stronger.
3. MEZON lite controllers also have a smaller, flatter, heat sink than normal MEZON controllers.
To make matters worse, that this smaller heat sink is also covered all around by the shrink tube of the regulator.
4. A reduction in the regulator opening in the transmitter brings no improvement, on the contrary, the controller gets even hotter in operation, since it has to tackle constantly and never fully through can. Deadly in the summer for the regulator.

Please inform your customers about these things when buying. Our recommendation for F3A use is either a Master MEZON 130 as a BEC controller, or at least a Master MEZON 115 Opto, better a MEZON 135 Opto in the optocoupler version. With these stronger controllers, the Lite version is conceivable, if not optimal.

With our F3A recommendations in the Hacker shop you will find no indication of the small Master MEZON controllers.

The argument for higher weight or additional costs certainly does not apply. When weight difference we speak of about 10 gramm, at the cost of a few euros. If a controller that is too small burns down, the damage is even more costly.
Thanks for your support. With your help we can certainly reduce new failures in the F3A scene.
