some interesting replies there , thank you guys . Three reasons for trying brushless ,
1, because i have never used brushless before
2, to get a bit more speed from the hull
3, to get more duration ,run time
#1 is simple #2 it seems that the hull/ motor design is at its optimum , and #3 still thinking about that.
So it looks like an equivilent motor to the recomended 540 which if i have got it right would be a 2,300/2,500 kv motor ,
running with the correct esc ,and possibly a larger prop . as for the duration if i was to use a 2c lipo pack of 2,500 ma would this be suficcient , this is where i fail as i dont realy know , and i don't realy want to spend / buy the wrong gear .
I have seen motors at £20. and £100 and then you still have to buy the esc battery and then the charger, if i don't know i could be waisting money, so what , from where and how much please.
