Corona , Astro 4t , 5t ?
Going to get a Corona . Sites that sell brushless motors for them sell the 4 turn astro 020 . I already have a 5 turn 020 . How much difference between the 4t and the 5t performance wise ? Anyone care to hazard a guess ?

I think you'll find that the 4 turn has a Kv of 3,300 while for the 5 turn the Kv is 2,576 so at the least you'd need a different pinion to keep the headspeed in the 1,600..1,800 range (it's geared 11:1 with the 9 tooth pinion). However while the max current of the 4 turn is 35A, the max current for 5 turn is just 20A so you may have problems there trying to use it - best to contact Astoflight directly about this for advice!
