Huge upgrade.

This is a big rocket šŸš€. Canā€™t wait to see it launch/fly. 29mm engines are new to me, very excited. The reason I gave it 4 stars- no stickers were included with this kit. Come on Estes, throw in a sheet of stickers.

Classic Pro Series II 3" Rocket - I'm a Fan!

It's good to see yet another PSII builder's kit back. This one is a good strong bird, with sturdy, well-fitting components. It goes together very well. I recommend adding a length of kevlar cord between the body and the elastic to help avoid nose kick-back damage. Also, use plenty of epoxy fillets between the fins and body, inside and out if you're going to fly with composites. Your Leviathan will be built to last. Otherwise, this PSII kit great as is. I've built two Leviathans, one decorated like a Patriot M104 (fins clipped and nose weight added), and one decorated in white and black like the old classic North Coast Falcon X000 series (modified to just 3 fins). Fly the Leviathon with the F15-4 and it's like watching a really majestic Big Bertha! Moreover, being so sturdy, this bird zips along well on about any motor you can fit in it. Just be sure you have an appropriate delay. Rail guides (or buttons) and a Chute-Release are advised with bigger motors to help you get it back!
