Think Saturn V




Three times the amount of the smaller package.

My guess is that is a typo and is supposed to be an E30T (Blue Thunder propellant) whereas an E30W (White Lightning propellant) is a different propellant formulation.

Notice that Estes is selecting the easier to light formulations, with Blue Thunder being notoriously easy to light.

This is going to be interesting to see how Estes markets the MPR/composite motors, especially in their new catalog.

The other one being the Sonic Igniter info card stating "For use with D - G Composite Model Rocket Igniters!"

So that isn't the rumored Sheryl Crow Mega Super Recovery Wadding, only one square per flight!

Yes, of course, but what I was referring to is the current E30-4,7 is a Blue Thunder. I was wondering if the 'W' wasn't a mis-type, or if the '30' should've been '20' (I flew my Maxi-Brute Pershing on an E20-4W a couple of months ago).

------------------

Many moon ago, there was a guy in the old "MASER" section in Atlanta that modded his Centuri Saturn V for FSI F100 motors (which we all know now was really more like an E40). Great flights, all the time.

Get dimensions on that 24mm casing. If it is longer than a D (like E9 length), then you could make an E30 with W propellant. Or there could be a new variation of W.

We'll find out when it's time.

I hadn't considered that Roy, but you might be right about that being an E20 instead of the E30. That would make sense because AT (AFAIK) was using the E20 to break into the LHS market and E20s are a more modest, entry-level AP motor.

Greg

Remember the G80FWL? Maybe that's the 'W'??????

It was a Typo. It should be E30-4,7 T
