Finally got to ride about 9 miles including 3 on our high speed cemetary test track and have a number of observations. Test conditions were 91F with 90% humidity. 42 volt very over the hill NiMh pack. 300 lbs of trike and rider.
1. The motor has less starup torque than the MY1018z, but comes on strong about 5 mph up to top speed of about 17 mph.
2. U need to be in the right gear to start, or motor makes growling noises.
3. Much quieter than MY1018z but does make slight howl on startup, which goes away at about 3-5 mph and never returns at high speed.
4. Freewheel is excellent which allows superb coast compared to 16" 409CL brushed.
5. CL Brushed is quietest of three.
6. This motor cries out for more power, which will happen soon (48volt 16 AH Ping will be ordered next week)
7. Can determine efficiency by recharge with Wattmeter later today, but:
a. Controller was warm not hot
b. Motor was warm but could keep my hand on it for >5 sec.
c. 30 amp fuse was hot??????
d. Battery was slightly warm.
All this after final 1/2 mile 8% hillclimb at end of ride!
Conclusion: About equal or slightly better than my trusty old P2A brushed from Solarbbq, at less cost, with much higher top speed in 20" wheel.
(Bretts P2A no longer availible)
Should be killer with 48 volts!
