Dale,
That is the same motor that I have in my Conquest. On a 6s system with a APC 13x10 i
t is turning 10,778 on the ground at nearly 1,600 watts. I am ok with the speed of my C4e as it feels graceful and smooth to me. It fits my style and the Conquest IV was designed for the YS long stroke and a slower flight speed.
The 8s solution is interesting to get a plane closer to a YS short stroke performace. I bet it fits the style of the EU1A perfectly.
I'd be curious how many amps you are pulling. I'm pulling 68 amps max. I get 8 plus minutes flight time and I'm using about 80% of the 5000 mAh battery capacity. No problem for the Advanced pattern but would be challenged to fly masters. How much flight time are you getting if you take the battery to 20%?
Your EU-1A is about the same all-up weight as my C4e. I'd be happier with a less than 9 lbs airplane, but is still great. I suspect that a ground-up designed pattern plane designed for E-Power could be build and flown at 8 1/2 lbs which would be great. (Super Chipmunk 120s)
I can't wait to see your plane in person. I hope that you and Jon and make it to the next Classic Pattern contest.
