as far as performnce there is not one plane that will rival the Hobby lobby offerings. GWS is great due to cost but its a toy and flys like a toy. Go to the GWS wesite and you will see this plane fly in Japan and you can see how under powered it looks in the video.
I have the GWS tigher moth and the a10 both are good planes.The tiger moth is better and the A10 is way underpowered and very very pitch sencitive .

Megatech are toys ! Same deal the mags review these kist like there a god send but early post siad there were always radio problems with the no name radio in these planes.

Alpha/Hobby lobby is the most experienced company in electric,They were doing electric before it was popular. I have three of there scorpio kits and the performance will rival gas on a simple geared 300 on 6 cells.
The new alpha kits can be seem flying on there web-the down side is they are all thin highly detailed foam and this is unforgiving in a high speed crash.
