I cut the radio tray to half and fixed it, now there is space for motor. I will remove the radiobox and plant motor there. Those LiPo packs are Zippy 5000mAh 11.1v 20C packs, and charger is GT-Power A8 ( same as Bantam BC8 ) .
Looks like I take MGM 16018 because MMM is not coming out on a time. I removed radiobox of and I am now using hydraulic heat shrinkable tube to wirings ;D .
