Please note that my suggestions above are not based on all the facts that you know. You mentioned that it flew for a few feet ... you were there and if you feel it was coming out straight/level and not veering, then all is good laterally.
If that is the case, and it comes out nice, altitude and power should be your focus for your next game plan. I'm not an expert but we can teach ourselves if we treat crashes as a learning experience. Wish they would invent a black box for rc
Watch carefully what happens during takeoff. I've gone through a lot of glue learning what to watch for and there are pilots where I fly that can get near anything in the air ... first time. They blow me away
