Good quality

Good buy

easy build and good quality

I do not see nc-50. I have bt-50. Will nc-55 fit bt-50?

I've built rockets since I was 13, finally got my dad with no experience building out the SST Sonic Boom 30" with me at his age of 88 at the same time to get him into rocketry with me at his age. He's a prior Engineer at Georgia Tech and pilot with Pan Am so he understands aerodynamic principles. I bought the SST and finished it out like a Pan Am Concorde plane, and we're going to launch them together in a few weeks. This rocket the Explorer is the last one I built before I bought the SST and enjoyed building for its complexity of the side exhausts and I'm giving it to my dad as one of his Xmas gifts for his next build. Both are expert kits but my dads already caught on well and building out his first one well; certainly, this one too!

Great build for a rocket bridging class 1 model rockets and class 2 high power rocketry. Flew great on the F15-6 with only a slight shake of the tail feathers as it got up to speed. I had to replace the two flat head machine screws in order to penetrate, thread, and grip the pre drilled holes better until the epoxy cures. The fin decals exceed the fin size so I skipped them. I’m looking forward to launching with an H motor next.

Makes using D&E engines easy in small 29 mm powered rockets.

Bought the AltiTrak to give as a gift. I can't really say what it does or what it is for but it was one of several things circled in an Estes Catalog so from what I do know about other things I've bought from the catalog it is probably one of the best, if not the best. The recipient is a 74 year old by the way so he researches all of his rocket stuff quite thoroughly. Wouldn't circle just anything. The AltiTrak was well packaged. Arrived in good time. And is now wrapped for Xmas. My friend will love it.

Excellent, simple, tool. Must have for advancing model building accuracy

Came in handy

Free catalog is great just by ordering a product

Engine adapters are sturdy plastic and work great for smaller fields or windy days when you don't want to use the bigger engine or for the economical option by going with the smaller engine

Fast shipping, packaged well. Engine adapters are great for different size engines depending on the wind or size field.

Great!
