We took the ‪@fmsmodelRC‬ 8s 1500kv motor and 120 amp ESC combo and tossed them into the Eflite Viper 90mm RC plane. It's debatable as to whether this is truly an upgrade overall, as some aspects of the jet do suffer while others improve. You get more lowend thrust at the cost of higher end speed. This could also be a case of wind interference, but the model's tendency to stall easier is definitely a consequence of adding more weight to the wings. It can be a super upgrade for those of you who want the most power under any circumstance.

SMC Batteries

We're flying on SMC Batteries from www.smcracing.com and you should too. The LiHV packs are outstanding and you won't believe how well they perform until you try them for yourself.

5280 RC

Be sure to pick up a BlueFire or TrueFire afterburner for this jet. Larry's afterburners look amazing brighter than what you can get elsewhere, and cheaper too:
