If you have the Saito then go for it! If you have not bought a motor, consider the 91FX or 108. The 108 provides killer vericle with 15X6 APC. The 91 will come in just under the 108 in power. Between 3 of us we have the CAP(friends), Staudacher(friends), and the Extra(mine), the Cap has the 108 the other to have OS 91's. Have not seen any of these that flew poorly yet! What ever you chose, you will not be disapointed. You might consider upgrading the hardware though.
