Stupid question...

I just looked at the cost of a 24mm RC case. It's about $90 - twice the price of a "normal" 24mm RMS case. Is there any way to use a reload for the RC case in the non-RC case? I've got a top closure that was ruined by blow-by. It could easily be converted to a plugged closure.
 
Not without making the motor into something uncertified. You could do it, but until AT says that's an approved use (plugging the forward closure of a normal 24mm RMS case) then you'd be outside the safety codes.

As I said in the other post, you can try rocketarium which lists them at $57 or try bay area rocketry which said he'd do something under $60...

Yeah, it's pricey no doubt but well worth it in my view:

I agree it is a pricey case. There is a good reason, though. The 24mm RMS RC case is machined from one slug of aluminum, with the end closure machined in place. Far more work than a normal case and separate end closure.

One reason it is done this way is to keep it very light for use in s8e type RC rocket gliders.
 
Tom, I used to believe that the RC case was lighter, but in fact it is exactly the same weight as the normal case with closures. However you don't have the weight of the delay element in the load but it's really a few grams different, and it is shorter, I thought for competition they actually use the single use E-6 since it is lighter..

For S8 at the WSMC, we use a single use motor because the FAI rules don't allow for reloads. The motors are E4-P rather than E6's, but close enough that we can practice with the E6 loads.

Don't physically plug it, just leave out powder.

The RC reloads don't have an ejection charge. The endcap needs to be plugged because otherwise 1) the engine would continuously vent, reducing chamber pressure and performance, and 2) what it would be venting is *fire*, usually not a good thing for the inside of the body tube.

Hmmm. I was told it was lighter. Interesting.

I know it is not typically used in competition, but it is typically used in practice sessions for S8E due to the lower cost per flight.
 
That kit looks familiar:) It's nice to see it in action.....
