Change your servo location and end this.
Did it too.
Looks ugly but prefer it!!!
Need to figure out a better receiver location...don't like the aerial going around the whole car!!
I also removed most of the plastic of the trays. Drilled on bottom, sides, no top covers...easier to change battery and keeps everything cool.
Have you ever finished a 30min final and opened the trays right away...you will be suppriced of the heat in there. Not only was it thermalling the futaba receivers, it can cook those batteries and shorten there life...thus people having problems with batteries...this happenes to all 1/8 cars not only on the serpent.
