Arrma announced this morning that they will be doing a running update to the MEGA line similar to how the 6s line receives updates (V2,V3, etc.). The same basic form remains for the familiar chassis but numerous small changes and upgrades have found their way onto the platform.
The most important upgrade for anyone who owns a V1 is going to be the new diffs and slipper assembly. The diffs are now taken directly from the 4s line and have steel inputs instead of the V1’s plastic pieces. The new slipper features a castellated and the motor mount now features a sliding adjustment. Accessing the power module is now easier thanks to a larger pull tab molded into the mount. The V1 could be a chore removing the power module as the tab was rather small, making this a welcome change. The entire drivetrain spins on rubber sealed ball bearings for efficient power transfer and longer service intervals.
Supporting the upgraded drivetrain is a new, stronger chassis with revised steering. The chassis now features retained hinge pin plates and increased strength in crucial areas to prevent excessive flex and possible breakage. The side dirt guards are slightly taller to keep debris out of the chassis tub while the steering has been updated to allow debris to escape before fouling the linkage. The new servo horn is a 23t spline unit with a built in servo saver and is attached to a new Spektrum SPMS650 servo. The new servo has 20% more torque than the ADS-5 it replaces (84oz-in or 6kg/cm) and appears to have plastic gears. The 12t 550 motor returns as does the waterproof MEGA waterproof esc which now has an IC3 connector attached. The 7-cell 3300mAh NiMH battery (up from 2400mAh in the V1) is a hump style pack and gets retained by velcro straps inside the spacious battery tray. A basic wall charger is included for out of the box convenience.
Two new graphics options are offered for the V2 MEGA: a Red and Black as well as a Blue and White variant. Updated, stronger bumpers flank the chassis while the dBoots Fortress tires are now vented (the wheels are sealed, though).
Rounding out the list of changes are a new transmitter and receiver combo. Gone are the days of the Tactic radio and in its place is a new Spektrum SLT3 3-channel transmitter and SLR300 waterproof 2.4gHz receiver. The SLT protocol is faster than the outgoing radio system for quicker response to inputs and a more controlled driving experience. Steering and throttle feel are improved compared to the Tactic and the Spektrum also improves the ergonomics of the grip and wheel locations. A 50% and 75% throttle option is available at the transmitter for beginner drivers and a two-position switch for the third channel is located within easy reach of the trigger.
