RE: Hirobo Cap 232 15 size ARF balancing?
Yes, that was another issue. Its a common design for small planes and most of the time it works ok if done properly. The wire they give you is too weak. I got some piano wire (hobby shop or some hardware stores) the next gauge larger and used the original as a template. The piano wire is much stiffer wire. Make sure you predrill the elevator before sticking the prongs in and once everything is test fitted (make sure you test fit) I use a drop of medium ca to strengthen the hole and then slide the wire in. I always use an exacto and cut away a guide shaft on the elevator halves so that the wire can recess in and not cause a gap when you hinge them. You will always get a little offset at full deflection since the servo horn will be pushing up on one side but remember you are dealing with a small plane and this won't 3D anyway so you'll want to keep your throws modest. Best prop for this plane on my 15 LA was the master airscrew combat props which are 8x3 and blue in color.
