Yesterday I went to do a pre-check before I took the Tower trainer up for a flight and the tx box would not power up.
This is not the first time this has happened. This is the radio equipment from Alpha One (RIP). The first time it happened it went out after the first charge. The tx box from Alpha Two did the same thing after the initial charge. They claim it is because of bad fuses but they don't know why it is still doing it.
I tried to get them to send me fuses so I can make the repair myself and not lose 2 weeks of flying time but they refused. I told them I am getting sick of paying for shipping on this matter and they said they would send a pre-paid label. (there's another week.).

I would like to know what you guy's think I should do to rectify this. I have concerns of this thing going to hell while I am in the air so I don't want to void any warranty by going ahead and trying to fix the thing on my own. But if it always goes out the way it has been(when I turn on the box) I would think it would be OK to risk voiding the warranty.( Confused)
Also I have alway's used only the original charging equipment when charging these things and I also sent back the charger last time and it checked fine. So I don't think that is the problem.

Suggestions?
