RE: 30 minutes flight time from my Super Sportster EP!
Ok, yer right, you did say you used the nitro 9x8 on the Lipos. My bad. But look, if the plane would go straight up with the APC 9x8, couldn't you have throttled back? Have you figured out how much current you had to be drawing at WOT to knock a 4.5 Amp battery down to BEC cutoff in 6 minutes? Oh well, that's over with now.
I know what you mean about the having all the extra hardware on hand . I have two of the SSEP stock power systems as well as the T-600 setup and the S-600 motor. I was thinking of a profile twin for the SSEP systems. Maybe a SPAD P-38? Wonder if there's one on SPADs R us.
