The maximum voltage for a standard alkaline dry cell battery is 1.6-1.65V.. so thats 6.6V max for four. Pretty close to the 7V you would get from a 5s MiHh but it's still conceivable (though...

It wasnt the Rx i was thinking about, it was the voltage rating of the servos. For standard (non-HV) servos maximum voltage is usually 6V, your battery will have been supplying 7V.. this could...

That's something I've never seen on my own models or anyone elses. I don't doubt that you experienced it but take my word that it's not a common problem.

Funny, because i've got digitals in almost all my models and i don't have any trouble at all. They are all running either 6v or 8v for the HV types. I'd never buy anything else unless it was a cheap...

Yeah but you don't want to go much less then half square (i.e. pitch about half of diameter) otherwise you don't have enough speed for higher energy 3D stunts. 3D flying isn't all about hanging on...

The Torque 4016T-500 will handle a 16x7 prop, you should have plenty of performance with that prop fitted. The slightly higher Kv of the Torque motor compared to the recommended eFlite motor will...

Discharge power on the Accucel along with most other 50W chargers is a laughable 5W. That means that if discharging a fully charged 4s Lipo (about 16V) then the discharge current is calculated at...
