I did a Range Check today before the first flight test of my Euro Sport. Radio is a 10X with synth module and a Scan Select R2000 reciever. Revelution Whip antenna. Range with the Antenna off was only about 60 feet. In other airplanes I could walk over 120 feet and never lose range. Does this seem short? The manal says install antenna but NOT to extend it. I always have heard that on the TX for the range check you should remove the Antenna?

Any help here is greatly appreciated..

Thanks, Dennis

P.S. no flight was made today!

Dennis,

60 feet is too short for a 10X with the antenna removed. We use 66 paces as our day-to-day check. That's about 180 feet. You've got some issue there. Do you have another JR receiver you can swap out? I would try that if you do to see what's up. If not, you can take the RX that's in the Euro out and put it on a box or something so its off the ground and check it with just a battery and a single servo. If you still get only 60', you've got a problem with the receiver, most likely. If it range checks OK that way, then put it back in the Euro in the installed location, but only connect that one servo and battery again. If that's OK, connect the installed battery pack in the plane and check again. Then connect one of the servos in the plane and check, etc. That should lead you to what the problem is...

Dennis.. Bob's suggestions are very good and will help you find the source of your problem.

You didn't tell us if this range check was Powered Up or Baseline, you should do both! A normal Baseline for that radio should be around 300 feet +- 10% (ant. removed) double that with the antenna mounted and adjusted to 7 inches in length 600 feet!

Powered Up range check should be Hold / fail-safe free no more than 10 - (15% max) shorter distance than your Baseline! Bottom-line in my opinion no less than (225 feet min) Powered Up ant. removed.
