Flight report when it happens.



That Coaster bird turne our really sweet. Those other are wicked as well. Clear skies, and now wind when you fly.

Just remember that the 30lb Coaster engine was actually an F67 in today's terms.....It was called an F15 back then as it's average thrust was 15 lb/sec . The max or peak thrust was 35 lb/s so that's 156 N/s!!!!!! Also Coaster only made -0 an -4 for their F15 and F25 (F67/F111 in Netwons). They made -0 and -3 for their F11 (F49)

I can now report that a Coaster Dynasoar Centauri has flown successfully under RC control. Pics and video coming.

Boost was excellent on the E6 with minor roll input needed and the Centauri just about specked out in the partly cloudy sky.

Only issue was an excessively nose heavy condition on the first flight. This, combined with the small elevons of the original, made it hard to flair enough for a good landing. It was more of an arrival. Next fight will have the RX and battery moved aft and, likely, a bit of ballast added under the motor mount.

Once I get a couple more good flights with the original layout, I plan on removing the stock elevons and swapping them for ones with about .25 to .3" more cord.
