Generally, when you go above Mid power, using 29mm, you do not put a motor block in your motor tube. Many of the reload motors come with a motor block, or thrust ring, built into the motor casing itself. Yes their are many lengths of 29 mm motor, with the longest, non-hybrid, being the 29-360. The shortest 29mm I am aware of is the Aerotech reloadable 29 40-120 case, for E thru G power. If there is a local club, try to attend one of their launches, and lurk around and ask questions. Most of the hobbies people are very friendly. That is how I learned about High Power. You might try going to www.flyrockets.com .You can look around at their motor simulations, then go th some of their vendors links to find information for the motors. Happy hunting, and if you have more questions, be sure to ask, as some one here has the answers.
