My vote is for a 1509 w/the kv depending on set up. I have a 1509 3300kv running in my crt.5 on 3s and it is perfect
1. MBX-6 T8 1900KV, RX8 ON 4S
2. MBX-5T 1520, MMM ON 5S
3. MBX-5 ONROAD CONVERSION 1515, MMM ON 5S
4. MRX-3 ON ROAD CONVERSION 1512, MMM ON 6S
5. TEN T 2650 T8, MMP ON 3S
is the differance between the 1409 and 1509, other than size, torque? am i correct in thinking the 1509 has more torque?
1400 shares the same rotor as the 1500 series but has a diameter that is just over 36mm. power output would be marginal ,you won't notice the difference
