Thanks again
We have a guy at our field flying a stock setup and he uses a 3 cell 3200 and it does 70mph or so. not great vertical, but ok. His set-up is probably 350-400 watts
With the TP 2100 3S 18C he is getting 250 watts. Like I said the DF flies but that is it.
He is going to buy a ThunderPower 3S 2500 25C V2 ( I think these are the specs )
or a FlighPower EVO 3S 25 2500 25C . 2500's to keep the weight down .
According to motocalc the EVO will give us 135 W / lb out . Nothing balastic but should fly nice
This will tell us if the origional pack was poor.
If all else fails I will buy it off him for my F27C Striker
