Hey guys,
I followed the manual for the steering link that states to have a 1mm gap. Using a Hitec 7950 and spektrum dx6r and close to center as possible, i have to use lots of subtrim (150 points) . Is this normal? Or should i lengthen the link( tried and it gots a 5mm gap? Also, when i set my endpoints is like a 10% difference and one side with less doesnt seem to turn as well as the other. Any help will be appreciated.

It isn't good to have so much sub-trim with this radio. I think your endpoints will get closer when you minimize the sup-trim

I had this problem too on my SCT410. Same radio but with a Spektrum servo. I had to lengthen it as well. Not 5mm but quite a bit. Doesn't seem to be a problem.

Ill try to that out, what do you think is excessive in terms of subtrim in points?

Yes, i was bit surprised as well. It did end up being 150 pts of subtrim to the left even after zeroing everything and trying to center the servo horn

I think part of my problem was the 23t spline on the Spektrum servo. Moving the servo horn one tooth either way was well past center. I wouldn't think with the 25t spline on your servo, there would be as much of a problem.

When was having the issue, I spoke to Spektrum and they said try to have no more than 50-60. Even that seems excessive to me. Also, when in the higher numbers of sub-trim the DX6R radio does strange things. They have fixed it with an update, but IMO it is still worth fine tuning to get the sub-trim low double digits or less if possible.

Same as the hitec 7950 servo, im using the Tekno servo horn which is a 24T and it seems to be off by a tooth

site won't let me upload file- not from phone, laptop or from Photobucket. But there is about a 2.5-3mm gap between the rod ends on the link from the servo to the steering linkage.
I wil try again later, maybe the site will stop being cranky.

I had some problems with my tires ballooning last race. I'm curious if it's just a matter of going up in my diff oils or some other solution. I'm currently running the stock et48.3 setup with a Tekin 2000kv motor. I see a lot of other people running the same setup. Thanks for any help.
