Saturn V - E motor?

Post by Dave Falkne » Sat, 26 Dec 1998 04:00:00


The E15 with a 3 second delay would be perfect. I'd get some. I'm still
flying an old Estes 2001 Saturn on E15-4s, but they are just a bit too
long. And no, the Saturn won't shred on an E motor. Mine was one of the
last ones made that had an Estes E motor mount and orange spacer to use
D motors. Of course, I never trusted an Estes E in this model!

> are we sure that 3 seconds is the right time for a Saturn V on an E15?

Yeah, Roy -- from my experience with these models (and this motor), that
3 seconds is as close as one could get (in whole second increments).
The flight we did down at Kennedy in '94 used a -4 that I 'trimmed' to
(what I estimate as about) 2.8 to 2.9 seconds and it was absolutely
perfect timing.  This was a beefed up Estes kit (with some 'payload': 10
commemorative documents, two patches and a sheet of Apollo 11 stamps -
about 2 ounces, total).  With the additional thrust of those 4 mini A3-2
outboard motors, this should about counteract that 'commemorative
payload' -- such that a near-stock SatV and a single E15 would work out
about the same.

Nearly a decade of 'Challenger Commemorations' (that we do here) also
seems to confirm 3 seconds is far more accurate than 4.  These flights
are rather 'plain jane' (no payload) and the timing still seems the
same. (Sure, a Saturn for Challenger doesn't exactly 'fit' -- but I just
haven't found time to do a 1/100 Shuttle (and modify the
pad/launcher/tower) -- :)  One day.  One day.  "Pad A" for 'Saturn
configuration' -- "Pad B" for Shuttle -- that's the plan.)

It's somewhat an inertial thing here -- lighter models slow down quicker
- so the 'weight thing' (over a few ounces) seems to cancel out any
differences.  A 20 ounce Saturn coasts about the same as a 16 (or 14)
ounce one.

YMMV - but mine didn't.

It'll take at least several months to get them certified, yes? 8)
