View Full Version : Range problems
02-14-2001, 02:13 PM
After getting my maxx back together with the new ESC and finally completing the splashproofing (went with Thorbobs' helmet cover and butyl for all the gaps around servos. For a little added protection(don't want to be down another 4 weeks), placed servos and receiver inside balloons. Ran last night. Ya, I was having fun again...until the truck got 3 driveways away. It stalled, as I held the trigger and walked towards it it would jump back and forth then one more step and it took off.
Any thoughts for my first steps in troubleshooting range problems. I figure right now I get about 200 feet and do not feel this up to where it should be.

Go for the obvious first. Make sure the batteries in the radio are fresh, the antenna is extended fully, electrical connectors are tight, the crystals are in tight and both battery packs in the E-Maxx are basically the same capacity and both are fully charged. We have had our E-Maxx at least 300 feet away with no problems. What materials are your splashproofing components made from? Is the receiver antenna still coming through to the outside of the truck?

are you still running the stock motors if so check your capasitors on the motors make sure they r not broken. did your rx wire get shorteded (bad crash, cat, rogue x-acto knife) if so that could also b a cause of this. hope u get it fixed
bash till its broke

Jmaxx - thanks, The batteries are all new. Had to replace them all when my speedo came back cuz one of the boys turned the transmitter on, didn't notice http://www.traxxas.com/ubb/redface.gif
I'll double check the connections but all seemed good. I didn't check the crystals, I'll start there. Splashproofing was taken in part from Thorbob. I'm using the bicycle helmet cover setup. For the Batt trays I sealed them off with 2way tape and some plastic from a headset package. The gaps around the servos and the tranny I filled with butyl (winshield sealant). I have also taken the extra precaution of placing the servos and receiver inside of balloons. Oh and last but in my opinion 2nd most important is I opened up all components and filled them top to bottom with Dielectric grease. No dust or dirt or water or anything is getting to those circuits again http://www.traxxas.com/ubb/biggrin.gif My neighbor calls it overkill, but he's not the one that was 4weeks with Maxx envy. http://www.traxxas.com/ubb/wink.gif
bigg_tex, yes everything is still stock. I haven't added the 3rd cap to my cans yet...didn't think that would cause loss of range though. Now that you mention it though, my antenna tube was looking rather limp. http://www.traxxas.com/ubb/smile.gif
Thanks to both of you, I'll give these a shot and see if I can't improve my distance.

About your limp antenna tube. Ha. I was in my hobby shop and bought some cable linkage tubing for air planes and used it for my antenna tube. It was cheap (.60) for a long piece wich I could get like three out of it. It fit perfectly and seemed to be super heavy duty. I think the last time I bought the a replacment at the race track it was like close to a doller for just the one. Traxxas may sell em cheaper,I dont know.

Oh by the way, I souldered a new antenna wire on my recivers' circut board and it came a little long. should I cut it or will it be ok to just put a longer antenna tube on it. I hadn't had a chance to run it since I souldered it. It wont mess anything up to run it long will it?

Don't know a ton about RC - just getting started. But what I do know about RF communications from my Avionics background is this... be very careful about just soldering on a new antenna wire. If you don't get it just right what you effectively end up doing with the solder is creating a base load effect in your antenna. As far as the length of the actual antenna goes...I've heard it can be to your advantage to have as much as possible extended skyward. I believe that is why the racers run theirs up the tube and then down the exterior.
