I've never found a "plastic" glue that would stick to whatever plastics Estes uses. It all fails and generally peels right off. JB Weld Plastic bonder was the best of them but even that didn't hold when pressure was applied and the bubbling was a deal breaker.
I've found that pretty much any medium CA will work better then the best plastic cement but I prefer epoxy. Scuff up the mating surfaces where you can, clean the surfaces then apply epoxy and clamp.
For thin areas, I've warmed epoxy to the point where it's almost water like then brushed it over the joints and let it soak in. Wipe away the excess with alcohol.
