Not sure if this belongs here or in Mid-Power...
I have not flown anything bigger than a D yet, but I recently picked up a Super Big Bertha and a Big Daddy, both of which I had since learned are good candidates for E power - so I thought I'd give it a shot.
The only hobby shop around here that I know of that carries anything bigger than a D only has E9-8's. I didn't get them because 8 seconds just seemed like a bit too long of a delay. So, I'll be buying my engines online - but which ones? Would each rocket need a different size and/or delay, or are there any that would work in both? What about reloadables?
By the way - the Bertha is done except for the paint, and when I dry-fitted a D into it (with a 1-inch spacer), it started to jam up about halfway in. After I got it back out, I saw that the obstruction is a bump that seems to be in the general area of the top of the engine clip which I bent back to leave room for the longer E. Has anybody ever seen this before? I didn't force the engine past that bump for fear of getting it stuck. I think I'll use a longer E-size clip (rather than bending a D-size clip) for the Big Daddy.
One more thing - I read somewhere on the forum that E's give off enough heat during ejection that the rocket may only survive 3 or 4 flights before burning through. So is it necessary to coat the inside of the motor mount with epoxy or otherwise make an attempt at fireproofing? I think I might want to fly them both more than 4 times. Thanks...
