That's completely dependent on the volume of the space you're enclosing the TeleMini in.Also how large does the sampling hole in the airframe have to be for it to measure altitude accurately?
I'm enclosing it in the nose cone. I'll probably be using a V1 model and will sandwich the battery.What model do you have? The v1 model is 0.17 inches shorter than the v3 model. Also, do you plan to "sandwich" the battery with the board or lay them lengthwise beside one another?
