No offence ment JohnVH, but I have to agree with RoNeRiC 100%, GWS receivers ARE CRAP!!!!!! I have had one and only one, and the glithcing and interference it picked up caused my foamie to go down twice. Bought a 555, has been a perfect plane ever since. I just take the cover off if your worried about weight. The tiny bit of extra weight and cost far far outweight the cost and time to rebuild your plane IMHO. I personally just could not bring myself to buy another GWS receiver or recommend one to somebody. Hope you see my point where i'm coming from and no offence ment.
