pipemajor said it all, if your servos have a white red black wire, then you need to cut the tab off of the side of the plug, it is called a j-style plug i believe.. anyway, if you cut that off and remember that white is always your signal wire so it is always pointed to the top of the receiver or if your servos have orange red brown wire, you do not need to modify the plug at all, just remember the orange wire is the signal wire and always keep it on the top.

with that receiver, i suppose that you are taking some risk in putting it in a larger plane, but i have the park rx from spektrum and decided just about a week ago that i wanted to see how far i had control.. i flew a 43" wingspan foamie until i could not tell which way it was oriented and then i let it climb some more, when i cut the throttle, down it came and it had full control on the way down so i obviously never lost control.. so then i took it flat out away from me about 20' off the ground and got it to where it was hard to know which way it was facing and then brought it back... is it a risk? a slight one i would say. if you are flying at a club that is in the middle of a city, i wouldn't do it, but if your club is a few miles from population then i would have no problem in using that rx, just keep the arrow in sight well enough to know its orientation and you should have no trouble at all.. if you do lose it, spektrum's fail safe technology will kill the throttle and it will go down at a rate that shouldn't hurt anyone, and if your club is in the country, will only go down in trees or an open field, because you aren't going to lose signal right over the pits or anything, you will lose signal several hundred yards out from you, so if you do decide to range test it, do so in a direction that is away from any homes/people.. common sense, i know, but i don't think you will have any trouble using that receiver, as i use mine full range on my foamie and plan to use one on a spad i have with a .46 engine, just gonna keep it in kinda close popping balloons with it for combat practice...
