Ugh...groan....
There are WAY too many bad puns in this thread.

FSI always reccommended ridiculously large motors for all their kits.
There is no such thing as a model rocket that should fly on anything from an A to F motor. with hope of a recoverable F flight or a decent A flight.

Fly this one on an over-rated FSI E5-6 (most were under 20n-sec and not even a full-D) and kiss it goodbye. a real E such as an Aerotech E15 would send it into orbit.

My take is most birds have about a 3-letter range with the occasional 4. This goes from MMaxx size to L3. If it flies (and recovers) well on a given motor, going up more than two impulse classes is usually going to put it in orbit.

Default Big Rockets require Big Motors

Just finished building "interchangeable" fins for my 51" rocket about a month ago. Not happy when it got stuck on the pad using 3- "C's." In about week I'll be recieving my "E30-4." We'll see if it goes into orbit.

Using only 3 C's on any 51" rocket is asking for trouble if it is anything over a BT-60 (just big enough for a 3x18mm cluster) in diameter. Anything this big is begging for at LEAST a full 40n-sec E if not an F.
3 Estes C6's don't even add up to 30 n-sec of total impulse.

Hi: "Thrust vs Newtons vs wt," r all guides. The first 3 times I launched it, went up without a hitch! The problems arise when only 2 engines ignite or, as in this case, launch rod was dirty. Now I know not to rely on range officer, to clean rods b 4 each launch.
Thanks 4 the concern.

This week has been good - custom parts made by the Sandman arrived a few days ago, and now these:



They are absolutely first rate, with very nice decals!!

Mine were waiting for me when I came home from the skating rink. It made an otherwise bleak day a lot more tolerable. The only thing that kept me from making serious progress on one was a lack of the correct shade of green for the cone and tube fins. (That's a problem I'll rectify tomorrow.) I'm pretty sure I'll have one ready to fly for the next Quark launch weekend on the 23rd and 24th.
Now I can't wait to see what this month brings.

Is that what the Viking I's decals really looked like? I always thought that those illustrations from the 1971 FSI catalog were more "artistic" than "documentary."

Mine came in the mail today, too. The "VIKING" part of the decal seems a bit large for the BT, but that's not really a complaint. The parts are first rate - I think I'm going to have to bump this up to the front of the build list .
