I just joined Team Corally this weekend with a Red Kagama. I immediately started voiding the warranty by popping out the receiver for a RadioMaster ER5Ci bound to my MT12. I also swapped the dual XT90 setup for a single XT60 and added the voltage sense wire. Have a couple of CNHL 6S 6200mAH batteries that just barely fit the tray. While I was at it I also put in three short straps and on long one on the battery tray and two vent holes in the tires. Only had a short test run to make sure everything works like it should. This should burn on the grassy area next to the house. Imagine I'm going to run out of space fast running flat out. Much bigger, heavier and faster than the 1/10 Amp DB/MT 2S it is replacing. This will be fun once I find a better place to run it.
