Spend some money and build a real model. 1.5oz? Really?? Talk about a butterfly effect.
There's nothing wrong with the light weight. My grandson and I build stick and tissue crates that weigh 10 to 20 grams and take E-Flite electronics.
The main thing is to make sure that CG is a little fore. These micro models are unforgiving to aft CG.
I don't agree 100% with the guys that said even a small warp could be a problem. My grandson and I do not build 100% true surfaces, hardly ever on our small crates, yet these are trimmed to fly true all the time.
To me, the biggest issue is CG
