Mine was self-modding. I lost the upper half in the tall grass at the last launch, so for yuks I just replaced it all with a nosecone. Now I have what my daugter refers to as a "rick reck" aka the mini recker. It's about 3 feet tall, and sims out at 2240 feet on E9's (800 on C11s!).
Consider adding rail buttons if your club has a rail. That's a very tall rocket that can easily flop around on the pad on a windy day if you have up there on the stock lugs. I used 3 rail buttons--one at the aft end, one about halfway up the booster tube, & a third one at the bottom of the payload airframe.
With a big, open field, consider putting a trio of E9s instead of D12s... Hold 'em in there with some masking tape & let 'er rip!
well that is interesting, Jim just starts mumbling to him self and otherwise not a lot has been done here I sit wondering to myself gee if I was to build a booster???? how high would it go? how do I attach the booster? since the motor mounts are in a position as to prevent the typical attachment? can I put the booster on the outside of the body tube? with three d12-0 would its wieght require a recovery system? or would it survive the tumble? well I think the only way to truly know is to build and see?
okay thank you jim I didn't think about the problems with the cluster stage until you said it. well maybe I'll chad stage it just for fun? not that the rocket needs anything but why be normal? it can be real boreing sometimes. . I like the upscale idea but without the proper cirt in my pocket well I better just leave that alone and return to the table with a different idea tomarrow (whipped but not beeten)
