I purchased this as a conversion part for my Xray M18T. The RC18B wing is of Solid build quality as is the Anderson Body post which was made up with a custom aluminium L bracket. EXCELLENT value for money plus such cheap international shipping makes this a convenient hop up for a car that now is so much more balanced at high speed. Money well spent. I purchase one white and one black for my two Xray M18T's and the Anderson body mounts to compete the set..
