I made this to my Xray X12 to make it as inline as possible except for battery position plus I hate using tape to fasten the battery.
So I milled my own chassis with three new additional braces to fix the battery. Two on the sides and one right over the top center of the pack. The top brace unscrews from the bottom to release the battery. I used 10mm aluscrews so no need to loosen them complacently. Underneath the top brace I used high density foam with a double sided tape fixing it. It all works like a charm and mu chassis weighs 15grams less than stock. despite more parts!
Then I used a Sanwa SRG-HR servo in between the front wheels. The Tekin RS and Rx fits inline the center of the car now. Got a 45/55 weight ration front to back. Loving it
Very cool. I like the looks of it.
