Hugo, my quad (ht-fpv) has the vTx at the rear of the frame. Since there is no landing gear I have my antenna pointed up, but would prefer if it was down. I had an idea but not sure if it would be durable / feasible. What do you think?
My crude drawing is of the antenna with an extension and a right angle with enough length to allow it to bend upwards a few cm upon landing. Of course low flights might be an issue, or branches etc. Not sure how to handle that but had to start somewhere, ping pong ball?
