Lehner 1950/6 or Plettenberg BigMaxximum ?

[Serum]

1950/6 is too hot for 6S lipo imo. my wanderer/feigao 7XL preforms the same as a bigmaxximum, only being smoother (the wanderer is smoother) the schulze conrollers are quite harsh compared to the quark or the MGM. In your choice of the motor; it's wiser to take a lower KV rating. a 1950/8 or 9 would make more sence on 6S lipo.

I wouldn't take the bigmaxximum, i like the Lehners, and besides, with a lehner (2pole) you don't need a schulze controller. you can take a quark 125, MGM or BK. The bigmaxximums look good, but you don't want a BL setup, just for the looks, right!?

if you are looking for a mean and nimble racer, with incredible acceleration, you might even consider the 1930. it will spin up faster than a bigger/larger rotor. I currently have got a basic XL in one of my maxxes, (XL2400) and on 3S lipo, it weights 3.2 kg and it really jumps off when it comes to acceleration.

For lipo's you might consider getting the new formulation of the flightpowers. Daniel (dafni) has got them too. With the maxxamps lipo's he had nothing but trouble, and with these flightpowers, it's untamable.
