I don't quite know what you mean.

Are you saying that the plane lacks power or that the elevator does not work?

Could you please post the URL to the battery pack you "upgraded" to, and what charger you are using on it?


Even if you purchased a suitable battery there is a chance that the charger provided with the plane will not work with an aftermarket battery pack.

The balance charge ports on the chargers are not all compatible with each other, so you may not be seeing a charge on the battery.


Please answer the above questions so we can help.

Also the question was not about the plane being in the air or not, rather how the temperature rises during static tests.
