Newb: It's a bummer for sure having to rebuild again, but you don't want to quit flying all together while putting together a kit. Finding time to build a kit it difficult. My brother put together a tough kit in a week's time, and he worked on it from 6am to 9pm every day that week. Yep, he had LOTS of hours in on it. So, if you break that down to after work and weekends (and don't forget to make family time), you're looking at weeks to months to build a kit. You want to be grounded that entire time? I'm gonna gues no. So rebuild the trainer first, then start the kit. It'll give you some insight experience you will need to build the kit and your stick fingers won't get rusty either!
