I am sure you will continue to hear this and I also know you don't want to listen to it, but please start flying with a trainer type airplane.
You have invested a lot of time in that Zero kit and it is just not the right plane to learn on.
Buy yourself an ARF trainer, since you have been building this kit it will be very easy for you to glue it together, use your LA 40 engine and radio gear that you are buying for the Zero and start learning to fly. Once you have mastered the trainer just take the engine and radio gear out of it and bolt it in the Zero.
Most of the ARF trainers are pretty similar and they all work pretty good.
The Tower trainer is cheap $69.99 easy to order another inexpensive option is the World Models high wing Sky Raider, it was $78 out the door at the local hobby shop. Either of these planes will get the job of training done in fine fashion.
