Anyone have a B14, B8 or C9 they want to sell me?
The MPC C9 motor never went into production.

Two 13/18 adaptators have been built. Because of the couplers between stages and the way they stack I had to build them special for each stage.

Should be able to launch all three stages at the next club launch, assuming I can find some A10T-0 motors.

They look workable. Is the middle section of each adapter necessary? What do they weigh?

Hope you get a great flight!

The extra length helps with the friction fit that is needed to keep the adapter in place.

I finallllly got some A10-0Ts. So this is going up on Saturday,, assuming the winds are reasonable. C6-0 -> A10-0T -> A3-4T.

Every possible thing on this rocket is friction fit, which is nerve wracking, but we'll see if my skills are up to the challenge.

Just make sure the staging couplers are not too tight, and you'll be fine.
See post #15 in this thread from some guy named John Boren.
Good luck!

Don’t see if this was already verified but from the Microsonde font, I’m guessing 1978.

Produced from 1970-1978.
Instructions say if you want to order engines directly from MPC, it's 3 for $1.25. Catalog price for the kit was$3.
Good times.
EDIT: Of course minimum wage was something like \$1.60/hr.

The couplers are loose enough that I'm using small pieces of tape on the exterior body to hold the stages together until separation.

Not flown today due to 10-12 mph winds gusting to 15.

I want to fly this thing, but mama didn't raise no fool.
