Hi-ya Captin na had a look at me JR2610 and it has full stick but I did buy it 2nd hand so maybe the dude who had it before me had removed the stops,did not know that JR had reduced throttle stick so looks like I will have to get used to it never know maybe it will work out better I use a sanwa RD6000 on my zoom 400 and that has reduced throttle movment and I love it but the raptor is a different beast all together think it will be a right handfull as I am still learning get's the old heart rate goin though

would anyone know if there are any stops that can be removed or is it best left well alone

It is quite possible to remove the thow limit stops and recalibrate the tx. I don't know that I would do it but I think it can be done. (at your own risk of course

)

C Chaos,

It is only is the US that you have restrictions. Elsewhere if the Jr Tx has a 3+1 dig trim ( ie Analog trim on throttle ) then and only then will you find stick limiters. This is because you cannot change the stick mode. Any other full dig trim system will be user stick mode changeable and therefore will not have limiters fitted.

All because US flyers think they need analog throttle trim. Oh well. I've always preferred digital throttle trim myself.

AFAIK you can't just recalibrate it. Contact Helgar and ask them if they can recalibrate it post removal.

This thread is the reason I think you can recalibrate the sticks after removing the limit devices. http://www.rcgroups.com/forums/showthread.php?t=609802
Unless you see a method for doing in the thread you may have to figure it out on your own. This thread just gets you to that point. As mentioned on almost every post, you do this at your own risk.

Hello everyone,
I may or may not be able to switch trims as well and may have to live with radio with half swapped setup. so I have now decided to wait till MODE-1 stocks arrive.

Thanks for your inputs,
Ranna

I just got my DX7 new and have noticed my grey antenna wires are exposed with the copper wire where it comes out of the case. Should I be worried?

duceduc - I doubt it will impair performance but I also don't think it should be exposed.

duceduc ,

I agree that they probably should not be exposed ....

If it concerns you, get some ELECTRONIC GRADE silicone adhesive and put a little dab at the offending site....

PS-- Hard to tell from the picture but if your receiver is "hard mounted", I would consider remounting it with some vibration absorbing material....

If the antenna wire is soldered to the board immediately inside the plastic case, that would explain the bare wire. That also identifies a flexing/weak point on the antenna wire in the event of too much bending back and forth. A design modification can fix this.

I popped the case and shrunk a couple small layers of shrink tube (one layer a little longer than the other layer) on the wires where they exit the case and popped the case back together on 'em so now the wires are held protected and flex instead of bend at the case exits.

Nice idea! I worry that the whiskers will get flexed around, wear, and break at some point. Any tricks to popping the case? With what?

Thanks,
Tom

Sorry - I actually didn't need to use any tool at all - I simply flexed the case off the tabs that hold it together by pushing the lower section one way and the upper section the other way and lifting the upper section up around the tabs - Pretty slick and easy as long as you don't tweak it too hard and break it -

One layer of shrink tube is probably enough - Two layers on mine is squished pretty tight between the case.
