The Tricopter 355 is the largest of the tricopter made by Armattan. The larger size helps with visibility in the distance and bigger popellers allow for a heavier payload.
The builds and DIY kits come with 2822/1800KV motors and 30 amps, simonk ESCs. The bare frame weighs 168 grams.
The ideal propeller size is 8 inch but it can also be fitted with 9 inch propellers. The servos that come with these models may vary. The servos are digital with metal gears as well as ball bearings and a minimum of 3.0Kg stall torque. This is plenty of torque for the most advanced acrobatics.
