hi, the razzle is a great flier we had a saito 91 in ours and it flew fine but it needed more so we now run it with a 91fx with unbelievable oomph a14x6 will take it to the moon. don't forget these planes are soft because they are built so light. i read some where that these new super light fun fliers are built for flight and not for crashing.
do strengthen the tail!!
we also modified our wings and she now harriers and rolls much better.l
