I was the one that asked for the 10/12s sticks... made a post about it earlier, but its hidden somewhere...
Here it is again:
The packs i mean would be like 10 and 12S sticks, ranging from 3000/3300 4000, 4400/4500 and 5000/5300. Those are the most common packs for Mikado logo's, the Trex 600PRO, (and other 600 sizes that are becoming much more popular on HV setups), and popular 700 size electric helicopters like the Trex 700, Synergy E6/7 Series, the New Goblin series, and even helicopters like Henseleit's.
Im sure they will be a wanted item.
A splitpack is better than a 12s yes, because that way, people dont have to buy a 10+ cell charger.. since there is already an alu plate on top of the cells, you could extend that plate to protect the whole stick and give it strength.
If you need someone to test them.... shoot me a PM.
