Notes for safety： 1． This RC heli model is not a low motivity doll. It is with big force and high flying speed. Please try it under the guiding of somebody experienced. 2．Please fly under a safe condition. 3．After switch on the electricity, the heli might shake strongly or out of control when affected by electronic waves. Such as near the domestic electronic equipment, under a high pressure environment, or there is other remote controller using the same radio channel, or other unidentified wave. .So remember to keep a far and safe distance from these and people. Please be alert every minute and second. 4．The battery used here might cause a fire in case of short, dampness, bump, cracking and over loading. 5．This heli has a max rev. The max rev of the frame part is 3300rpm, and the max rev of main rotor, please look at the sign on the package. Please do not try to test it with the max rev. as in this situation the main rotor will be overloaded. 6． Please check and renew the main rotor frequently, as the stuff will be degraded and with less intensity after fierce and high speed movement. 7．Please electricize the battery according to the guide line related, so as to prevent any danger. 8． The players should be responsible for their own deed and responsible for the damage and injury happened during the operation process, if any. 9． The bearing would have cracks when the plan is crashed，You had better check it carefully or change it directly。 10．When the rotation became unusual, please change the bearing immediately。When you do your flying，please check it every 3 hours and change it every 9 hours。 11．The speed should not exceed 3200RPM and the weight of the blade should not over 20g。I mentioned those to avoid the fly off of the blade due to the damaged bearing. The high speed blade would have very strong destructive ability, please take care。

Power System： 1) The motor and the ESC need matching test. Please choose our motors and ESC. In the NORM condition, the highest speed of the main rotor of the SJM400
Pro is 2200~2600rpm; in the ST-1 condition, it is
2800~3200rpm. 2) Through gear decelerating structure, the motor can make the main rotor rotate. You can choose 10T, 12T, 14T motor copper gears (attached to the kit) to change the decelerating speed. ( SJM400 PRO ’s main rotor gear is 180T) V (battery voltage) × Kv (motor rev /v of)× the number of motor’s teeth÷180(main rotor gear) = the rev of the main rotor 3) Our ESC (25A / 30A, BEC3A) can be matched with .3s 11.1V and 4s 14.8V Li-battery. 4) Please use (3s) 11.1V, 1300~2000mAH, and over 12c Li-battery.
