I purchased the tower voyager as my second airplane and instead of mounting the engine inverted(friend had the same issue as described earlier) I mounted it rightside up and the airplane flew great. It performed very well and I was very happy with it until I put into the ground when I did not did not see that it was inverted. With an OS46 engine and a 11x7 prop it was a fast flyer and a good aerobatic airplane. Landings were fun and enjoyable, it was a good second plane. I belive that the airplane is onsale at this time for 104.99 and depending on if you purchase over 150 you could get 15 dollars off your order. Anyway it is a good second airplane.
