Experimentation for sure !!! What's interesting is how the performance of many of the midrange (say, 40 to 60) electric motors can be altered by the battery and the ESC. A .46 or a .61 has been benchmarked over the years and standardized for performance.

While electrics have been around for 30 years, all the NEW electrics, ESCs, and batteries have yet to be 'benchmarked' to everyones satisfaction ... vis a vis, so many changes in just a few short years.

I'm sure you will like the 500 watts on the Avistar ... i've reconfirmed the 5 pound flying weight (glo standard, but a target for electric) ... it should be quite peppy ... and very aerobatic !!! Make sure your ESC will deliver the 500 by multiplying the Amps X Volts !!! E.G., my Jeti 40 and 4S2P would deliver a 40 x 4 x 3.7 = 592 watts MAXIMUM ... good for take off of the 6.5 pound NexSTAR and more than enough for 423 watt normal flight. By now, i think you already know that ... just wanted to make sure you didn't forget ... ... now, as long as i don't rip the wings off during take off ... ...


PPS (several days later) ... i seem to have forgot you have a whattmeter ... ooops ... mea culpa ...
