David,

I have both the Ultra Stick 40 and the Ultra Stick 60. I have an OS 50SX on the 40 and a YS 91 on the 60. I would highly recommend the 60 as your next plane but you really need to put a 4 stroke on it for the most fun. It floats in at walking speed but has unlimited vertical. IMO it is easier to fly than a 40 size trainer. I set my radio up for flaperons and it will crawl in for a landing.

One piece of advice, put in another 30-40 hours of flying with the trainer before you move on to another plane. Make your mistakes with a lesser plane.

Sticks are an excellent choice for a 2nd plane.

Just my 2 pennies.
