In past -all electric ARF planes from great planes were crap -to heavey , under powered , The old Zero was a brick .I wont buy electtric from them today
I have had luck with Sportsman avaition
Model Tech is a roll of the dice on the plane and release
Global- I like the value , again depends on the plane
V-mar - P51 is a brick sled
World -P40 is total crap and shows what happens when a foreign company has no respect for US military history , they should have called this a Piss40
