I ordered some Turnigy 2s 5000mah 20-30C packs for my sons electric quad and just for a laugh I thought ide strap one to the front of my 450 Sport with Scorpion -6 motor! I was pleasantly surprised to be able to do 3D with this setup! I did around 4 mins and only put about 1500mah back out of a safe 4000mah! The pack weighs 275g so is not exactly light but some of that is down to it being a hard case Li-po for RC car use. I reckon with a 4000mah standard 2s Li-po you'd be down to around 200g and 8-9 mins 3D flight!

60% of the time, it works every time!

I assume you're running about 2000rpm head speed on the 2s lipo and the 4400kV motor?

Not tachoed it but whatever headspeed you'd get from the 4400kv motor, 11T pinion, 2s, 100% throttle. 2300 ish?

I tried a 12T and it was better but not drastically.
