E-Max 8

This is my personal E-Max.
The frame was designed and cut in 2009 and the E-Max Prototype still flies today with the same frame and electronics.
This is the helicopter used for Yorkshire Model Heli Tuning & Lessons.

Several refinements have been made to the production version including:
• Slimmer battery clamps to allow the sleek Raptor Titan X50 canopy to fit
• The motor has been raised a further 25mm improving the CG
• 25mm thicker area between the motor and main gear frame cutout
• A base plate has been added to stiffen the already very rigid frame
• The battery panels have been enlarged to completely cover the batteries
