The Rapture will be a good first kit to build.
There is plenty to learn about kit building and you want something that you can complete without getting too frustrated with it.
The Rapture will be plenty of challenge for a first timer but you will be able to do it and have something to be proud of when you are finished.
By all accounts this is also an excellent flying plane that is fun and can improve your flying skills.
While you are doing this you will have more time to see a greater selection of 3d planes so you will be better informed on what to get and the power requirements for it to perform the way you want it to.
