RE: Question regarding compatibility

Servos and Receivers you may mix to your heart's content, as long as the connectors fit the socket. Connector polarity needs to be correct, but as long as the RX is less than 10 years old, you can't...

The limitation of prop size is related to the MOTOR / ESC combination, and the amperage they can handle.
Amperage is the Voltage divided by the Resistance (I = E/R). That means, if you have the...

RE: LiPo swollen or just the packaging?

I've got 3 3S-2500 cells that have been like that since the day I bought them, and that was over 2 years ago. They charge, hold a charge and give me great flight times, every time.

RE: Should a LiPo swell after being discharged to near zero Volts?

Swolen cells are often caused by draining a LiPo to nearly no volts. Doing so ruins the battery. [:o]

RE: Rubbing Alcohol

Isopropyl Alcohol should be available at your local pharmacy or possibly a grocery store. It's the stuff the doctor swabs your arm with before giving an injection or drawing blood. In 80% or better...

We use carbon tubes and ferrules all the time in stunt kites, up to 13mm diameter. Contact GWTW-kites and ask Steve or Chris about the specific diameter of tube you need, and tell them you'll need...

RE: crystal failer

Yep, it happens, but only rarely.  I've had crystals survive horrendous crashes without a glitch, and had one fail between using it one day and it being dead the next.  Maybe that's why they cost...

RE: Help required to find a profile foam plan

We use Sketchup from Google to generate the profile plans for our PhlatPrinters. You could output your file to a regular "ink" printer, but we don't have to.

RE: What works best for cutting out parts?

I'd use a PhlatPrinter with a 1/16" or 1/32" router bit. Draw the airfoil, generate the PhlatCode, shove in a sheet of balsa and 2 minutes later, you're gluing stuff together.
Of course, that's...

That 2S battery will give you 7.4 volts. :(
