E-flite mSR

E-flite mSR helicopter

After some months of not doing any flying I got the E-flite mSR helicopter out the cupboard and switched it on.

The transmitter showed 6.0V and so plugged the helicopter battery in and we were away. This is a great indoor helicopter that is challenging enough to keep the senses on edge – well for me anyway. The only issue was the helicopter started flashing after about a minute of flight and drifted to the floor with a loss of power. Hmmm, plugged the battery in to recharge and had another go….same thing, 1 minute of flight and then low power. Oh well, have another battery, this one must be dead.

The other battery was fine, lasting around 5 minutes (although I didn’t time it). So marked the cell as ok so as to know which one to use.

One nagging problem, that cell should not have failed as it really has not seen more than around 40 charges and I’ careful to let them cool before placing them back on charge after a flight. So, I plugged it back in the charger and tried again. This time leaving it in the charger well after the charging light had gone out. This time a much longer flight, so back on charge again (after letting it cool down) and appears to be back to normal.

All I can say is if a lithium ion cell appears to die after being left for sometime, cycle it and see if it comes back to life. Be careful and follow the manufacturers directions for discharge and charge but you may, just may find some life left in it.

The original review of the E-flite mSR is on the glue-it.com aircraft gallery pages.
