Remove and re-install the crystals on both the TX and the RX...

There have been numerous times that this clears up many of the issues surrounding both, as it seems that the contacts form a bit of a patina.

This may also be related to the problem you are seeing with the ESC, but I'm speculating...

Re: Rubbing.

This one is up to you.

Most inexpensive EDF's need a bit of work to make sure that rubbing does not occur.

A bit of sandpaper, while turning the fan blades, helps remove just enough plastic to prevent this from happening in flight.

Sport-Flyer magazine as well as Backyard Flyer magazine both had articles about preparing EDF's... including RTF ones.

You'll need to do this with most RTF and ARF edf's, the exceptions usually being the more expensive spread that come pre-dynamically balanced from the factory...



Re: Battery pack.

Out of curiosity have you put the pack on an intelligent charger/discharger to check it out?


In any event PM John here ( nitrostaff1 ) with the problem you are having... give him a few days to respond as he does not show up here every day.
