get a set of hitec 5475 digitals. You'll be glad you did. They are approx. 34.99 ea and work very well in small 3d applications
i can kit out that plane with perfectly good 3003's for the total cost of one of your Hi-tecs. a 46 won't be pulling them apart. for just over 2 Hi-tecs you can kit it out with 3010's
afford the best you can doesn't always make sence, sometimes it's just over kill
