RE: Recommendations for an E heli
I second getting the T-Rex but if you wanted something a little cheaper then the Heli-Max MX400 is a great heli. There is nothing wrong with the quality but its only $140. Of course you need a radio, four servos, brushless motor/speed control, and a gyro. It uses 3s1p 2100 li-po batteries so your 2500 should fit. Its not as 3D capable as the T-Rex but from what I heard its a little easier to fly because the blade grips are a little loose (but you can also fix that).
