Just got my EX1 UR to replace my Futaba 2PL. I'm experiencing some glitching with the new transmitter I never experienced before. Is the 2PL a better AM transmitter or do I have a problem with the EX1 UR? The only variable is the transmitters. I'm using the same crystal and same batteries. Would appreciate any help.

Just realized the AM module says its for the EX-10 Helios. Is this compatible with the EX1UR? I know this sounds like a dumb question but the module actually worked. It glitched at about 18' away from the transmitter other than that it worked great. Did I do some damage to the transmitter by using the wrong module?

After many years of racing, I aquired a EX-1 UR Tx. The radio previously I used for mini-z applications was an old Mars EX-1. The Mars was given to me by my good friend Mike Swauger many years ago when he raced electric on-road. The Mars was different in that he had a KO Propo larger grip for the handle and the spring tension on the steering wheel had more tension. After many years of using this for my mini-z cars, I got use to the higher spring tension on the Mars. My question is: How do I accomplish the same spring tension for my EX-1 UR radio ? Is there a spring tension adjustment or do I have to change out the spring to a stiffer version ? Thanks for your help.

Ok so after reading a bunch of posts I found out the EX-10 AM module is compatible with the EX1UR .... supposedly. So why does it glitch when my Futaba 2PL does not. Should I do the ADJVOL? Is there a problem with my antenna? I tried tightening and it just spins in both directions. Is this normal? Any input would be appreciated.

Pulled apart the UR today and found out that the I had to change out the spring. I went to Frys electronics and found some stiff silver lever springs. Changed them out and the UR is dialed to my liking.

Hello,

For years now I also have dealt with glitching with my AM and AD cars with the EX-10 Helios. Especially with my AD-Band, which should have less glitching and better signal reception because it is FM.....

Well, I recently bought a used EX-1UR to test out, and one day I put in the AD-Band module and tried my AD-MA010 that has ALWAYS glitched like crazy for me no matter what I tried... Guess what? It performed excellent. Much better than the Helios ever did. Now, I know that my Helios' first antenna it came with was faulty- It broke after a while unbeknownst to me and I was using it with a broken antenna for a long time I think. I replaced the Antenna, same OEM Black-matte antenna ($22 antenna, sheesh....) - BUT! With the EX10, Still the glitching is there with my AD car. I haven't run AM in a long time so I don't know how the glitching is with AM.

But this is aggravating to say the least. Hair-pulling aggravating actually that I have a $200+ Tx that I can't use reliably. Now I use the EX1-UR mostly but sometimes I use the Helios for 2.4 ASF, since that doesn't require the use of the Helios' built-in antenna. But IMO, the Helios' antenna is the culprit in why the AD and AM reception are always poor. Man, even my old KT-2 out-performed my Helios with the AM-module...

If you are set on using AM maybe you could contact KO. I am thinking about doing this actually now that I have found out that the Helios may be faulty, or the antenna at least might be.

But you are not alone Eman!! Let me know how you make out. Oh, and the antenna on the Helios should tighten the same as any bolt on a screw should, Right-Hand thread. It tightens down on mine. Yours sounds like it won't even tighten down, so yes, it seems there is a problem with your antenna. I would also try fully-extending your antenna and collapsing it again, and repeat this several times to check for bad links in the antenna. My old antenna had a few bad links and it slipped by my notice for years.

Exclamation 03 board to 02 chassis swap

I just put an 03 board into an 02 chassis. Did some wire switching. All works well. BUT one question i have is...........
You (KO) recomend the steering balance and travel at 70 max for 2.4 cars. All my cars are set-up in these perameters. With this 03 to 02 swap, for steering travel, i must set it at 100 or alittle more to get enough steering. Steering balence is 60-70 like it should be. Car works fine. Is this higher st. travel considered normal because of the 03 to 02 ? Or is there something i missed in the switch over?


THANKS

lfisminiz... i remember reading it somewhere that setting it too high might strip your servo gears... hope this helps...

Make sure you do this correctly because 100 L/R with 90 on D/R is too much...

Herman, thanks. This i know but this is an 02 with 03 board. The servo is the 02 servo. So its not like turning up the 03 settings.

felix2010...
sad to hear about your trouble with your helios... why not have it sent in for a diagnosis at least?

or try out your modules on a different helios to find out if its not the module that's the culprit... hope you get it fixed....

Felix: I received the correct module today and all is good. At least its as good as my 2PL as far as range. Overall its a better transmitter than the 2PL but, I wonder how stands up to the 3PK. The EX1 UR feels top heavy and I'm not sure how to set it down. I won't stand it up for fear of tipping and laying it on its back means it lying on the module. Guess I need the kick stand. For me buying the transmitter is a step toward 2.4ghz. Ordered my 2.4ghz module Saturday. Now I need to decide on a car. I might upgrade one of my MA's or maybe buy a LM. I'm disappointed know one from KO respond to my questions.

My 2 cents, I noticed end point set to 70 for the 03 did not allow full steering on my 03's so I slowly increased it just the end point until I heard the steering straining with left or right turn then I backed it one or two down or until the straining sound disapears. All this time my dual rate is set to 100% and my steering balance is set to 70. At this point I will set up the balance if i find left and right steering are not equal while doing this i never go over 70 on the balance. If after that I need to reduce or increase the steering high point I may, but again listening to the steering strain of either left or right and then backing it up until I dont hear it on both left and right turn.

I know this is a bit wordy, but I hope that helps
