As a rule of thumb, you will need glue and paint to complete the assembly and finishing of all model kits, which are purchased separately. In the eHobbies online store, each product has a “Required Components” tab where you will find a listing of additional items needed which are not included in the kit.
What rocket kits do you recommend for Cub Scouts based on a 30 minute assembly?
The Estes Alpha III Launch Set (part #EST1427) is a great set for scouts in a short time. It’s a starter set so it includes all of the launch supplies you need. For the other rockets, you can buy a Alpha III bulk pack (EST1751), which will provide savings by purchasing in bulk. In addition, you can purchase the recommended A8-3 bulk motors (EST1781) which includes engines, recovery wadding and igniters. Don’t forget that you will also need wood glue (ELG7000) and plastic cement (TES3516) to complete the model rocket.
