Its pretty much like the AW. I have a AW 50cc Ultimate with a DLE 55 running a 21x8 prop. To this day I have flowen the plane only 4 times. The reason is that the firewall keeps being pulled out! There is really NO WAY to get to it! On the last pull out I took and pulled it out and Hysuled the heck out of it!! I was ready to dump it!! I contact AW and the only thing Rosco said was "YOU ARE OVER POWERING IT". Now I bought this from TBM.... The GW 50cc Ultimate comes really with the same hardware....... Soometimes I wonder if its not the same factory...... Anyway, Yes, the GW Ultimate flies GREAT!! And the firewall doesn't come out!! This is my 2 cents worth.... I may catch some crap on this..But this was all done before I got GMP....
