Hi Dennis,
Okay, there are two Neus I would consider as swaps for a 2826/10.
For a baseline, the AXI weighs 6.4 oz, has a Kv of 920 (I think) a winding resistance of 0.04 Ohms and a no-load current of 1.7 A.
The 1905/2Y weighs the same 6.4 oz. has a Kv of 1025, a winding resistance of 0.025 Ohms and a no-load current of 0.9A. It will be more efficient at both light load and heavy load, thought the slightly higher Kv means that the resistive losses will be only 20% less than the AXI rather than the 40% based on just the relative resistance values. The 2Y can also possibly be used on 3S X 4000 mAh batteries with a 12-6 if you are flying a ship just at or under 50 oz. on 65 feet or less.
The 1905/2.5Y weighs the same 6.4 oz, has a Kv of 865, a resistance of 0.035 Ohms, and a no-load current of 0.7A. This is slightly more efficient than the AXI all around, and would probably allow the use of slightly smaller 4S batteries like a 3200 mAh if you can find them at less weight than the Pro-Lite 400's.
If and only if you are talking about a sub 50 ouncer, then the slightly smaller Neu 1706/1.5Y will produce a 3S 4000 mAh setup that will weigh under 16 oz.
The motor is 5.6 oz, with a Kv of 1225, Resistance of 0.022 Ohms, and no-load current of 1.5A. Expect to actually use 3000 ~ 3300 mAh to fly a schedule with a 50+ ouncer. Don't try this with a 60 ounce ship.
TMI?
