The plane was built by Lenny Keer, who is very knowlegible and uses lots of Neu motors. eCalc showing 45 amps and 500+ watts if I picked the right motor from the list. There’s about a jillion Neu motors listed! The watts are on the high side for this motor. The plan is probably not to go full bore the whole 30 seconds? Think I have a GM 15x8 in the box that I could run initially and see what the Castle reports for amps & watts.<div class=""><br class=""></div><div class="">CT</div><div class=""><br class=""></div><div class=""><br class=""><div><div class="">On Apr 17, 2020, at 7:57 PM, CURTIS SUTER via MT-ALES <<a href="mailto:mt-ales@lists.webworks.net" class="">mt-ales@lists.webworks.net</a>> wrote:</div><br class="Apple-interchange-newline"><div class="">

Looks awesome!
<div class=""> Seems like a huge prop for a 4s setup.</div>
<div class="">What’s the amp draw? I estimate 200m in 14 seconds.</div>

<div dir="ltr" class=""> Today I assembled the used Ultima 2 Super Strong that I bought used from John Hsu in Colorado. I wanted to check its weight and CG. Looks like it’ll be right at 56 ounces ready to fly, with acceptable CG. John furnished 3 sticks of ballast
at 5 ounces each. Adding ballast will shift CG forward a little. John had used a 4S power setup, so I followed suit with some 4S 850ma Venom Drone batteries. It has a Neu 1105 geared motor and a 16x10 GM prop mounted. My first venture into 4S power in
a glider. eCalc estimates climb rate of just under 14 m/s. Yikes!!!
