Right up front I want to say I like RoadRunner's 29mm SU motors.

There is a good variety of impulses, they light the first time every time (in my limited experience), their delays are accurate, I have experienced no CATOs, they come with a real two lead igniter, I almost always support the smaller manufacturers (Keeps the big boys honest) and Bob is a grand guy. We have exchanged a few emails and he seems quite nice. As a matter of fact, a couple of years back he sent us batch of free motors including F35's, F60's and G80's. You can't get much better than free motors!
So, my question is, what is your opinion of RoadRunner motors?
This is why I ask...
Last year at Southern Thunder I launched my King Kraken on an F60. In comparison to other motors in that class and propellant type the RR's just didn't seem to catch the attention of the onlookers. I thought it was great cause' I got her back in one piece. (Any launch you get your rocket back in one piece is a good launch) But even Trudy mentioned that the launch wasn't as dramatic as other F & G motors. I am guessing she means smoke, noise and flame.
As a comparison, here is my King Kraken lifting off on a Road Runner G80-4 at Saturday's MSRS launch in Memphis TN.
The youngsters loved it! Most had never seen any motor over a C and were awestruck by the spectacle.
The KK's second flight that day was on a G64-4
The kids and a few adults were much more enthusiastic about the G64.
Now I know the G64 is Whitelightening propellant and puts off a lot of smoke, but the motor has a deeper, more throaty roar that, in combination with the thick white smoke, seems to command more attention.
Am I imagining this?
