  1. Too flat hold more vertical oriented at launch try closer 60 deg and need more spin speed at launch and even a bit faster throw too. Keep trying. Presently not enough energy at launch to complete a full circuit, so generally seems to run out of travel at or before half way round a closed circuit of flight. Faster spin helps turning round the path, and more vertical throw angle directs also into tighter path around circuit. We made cheap backyard boomerangs from three ply, by rasping the needed bevel edges on a cut shape of plywood. Real boomerangs are heavier fashioned from suitable root wood pieces. It takes practice, and it is hard to teach in pure text, it does need observation of flight pattern and adjusting hold, amount of spin and launch speed according to how the flight progresses. A good flight should arrive back at almost same speed as launch and generally good hand catch height. Airmail shape influences the ideal looping path, so result of pathvshape is dependant on boomerang shaping as much as throw though range of throw is largely from how fast the throw, tightness of curve by spin rate , peak height of path by the vertical angle at launch. You will observe changes to the flight as you vary the different factors. Current throw being rather flat tends to fly curving upwards, flight speed drops off as height gains, spin reduces and flight falls back to ground at mostly furthest distance. Going more vertical oriented makes the flight curve more around path, rather than gain height and cause less speed loss thereby curving more back towards launch point. Too vertical and path closes before launch point to even passing across infront of launch starting another circuit. Launch speed how long the flight persists, also limited as mentioned by the upwards curving by too flat launch. Lack of enough spin but fast can leave the path open with boomerangs going wide past and even behind launch point. I am sure will see these effects when varying all factors. Given lack of current flight control and accuracy of where the boomerang ends its flight. PLEASE be carefull about the little ones. That boomerang will hurt if it hits them. One thing if you get hit if you fail to catch it, you will likely know how to duck and cover the head, maybe get bruises. At school many times kids throwing commercial and home made ones, have leven ost teeth or even received bleeding cuts, especially the carved solid wood genuine ones. The 3 ply fashioned ones actually have far less mass, so getting hit less painful but also thereby lose momentum quicker making getting a return flight a lot harder.
