I spent a great deal of time looking at kits for my NAR Level 2 certification flight. I'd built a couple of LOC kit in that past and was very impressed with them, so after a friend recommend the I-ROC for my L2 attempt, I bought one. I will admit that I wasn't sure about the kit when I first opened box. The nose cone is one of the longest in the market for a 5.5 inch rocket, but everything I read said that it was super stable and capable of handling a J motor. Just before I built the fin can, I decided to purchased an LOC 5.3 inch baffle kit since I planned to use a chute release instead using dual deployment. Note: The baffle was just a personal preference, but the I-ROC is plenty stable without it. I've flown my I-ROC twice. The first was a test flight using an AT I500. The rocket flew perfectly straight. If you like a quick take off, the I-ROC really scoots on an I500. You can't blink when it comes off the pad, but the test flight gave me confidence the I-ROC could easily handle a J motor. Yesterday, I flew it on an AT J270 for my Level 2 certification flight. Launch and recovery were textbook perfect, and it was a great feeling watching the I-ROC take flight on the AT J270. I'm glad I chose the I-ROC for my L2 flight. You can't go wrong with this rocket kit.
I have built and flown two of these rockets and they fly straight, can handle landings well, the instructions are more than adequate and the vehicle looks good on the pad! I highly recommend this rocket kit! Also, a great rocket to build your level one experience!
Great kit instructions weren't the best but was great for my junior level 1 certification on an H550 1700ft
