actually the smart idea would be to run gbb on when the temperature would be most stable, usually at night or early or later hours of the evening. I had 40-50fps swing between 20-25C plus direct sunlight on a kwa mp7, so less direct sun on you and stable air temps would help those huge power swings needing constant hop adjustments.
The other option is to run gbb indoors where temperatures are more controlled.
I futz with V2s, V3s and V6s. I could be wrong... but probably, most likely not, as far as I know.
