Hi,
A power cap, I did not know such an item exsisted. Reading that Ebay discription, it seems it stops low voltage shut down.
My problem is the the car and TX are fully charged, I put the car on the grid, walk to the rosterum, flick the stearing, and from time to time the strearing goes. Or, in a race on fully charged batterys I loose the RC for a split second or longer.
So basically, I don't think it's a voltage drop thing. But I know nothing of the power cap. If the power cap helps in keeping the link when the batterys are all fully charged then maybe it will stop my problem
It would be great if £4.50 will solve it. My daughter also has the same RC, so I can see what ever fix mine needs, is also going to have to be done on her's, even if that's a new £350 RC set

She loves her racing, so it will have to be done.
