Hi! I have an easy glider with permax 400 6V, and I want to change it for brushless ... but whitch one ? I'm beginner (with poor english :)) so problem is even bigger :/ and choice is huge. I'll be very gratefull for any suggestion. Only what i know is - that if I put new motor with gearbox I will not have to change anything with the "nose"(?). I would like to achieve good climbing (?)angle 45-60 degrees should be perfect I reckon. Thanks for Your time and help. Robert
