throttle exponential for off road

does anyone adjust their throttle expo for off road, i was considering tinkering with this adjustment for my 2wd short course truck.

SRG-BR servos with 451R reciever

Hello, I own an Airtronics M11X and I also have the RX451R reciever with the SRG-BR servos, till now I was using a 2cell lipo battery with a regulator but it blew up, I have heard of people using Li-Fe-Po batteries rated at 6.6 volts. Can I safely use that battery on my servos?

Does anybody make a screen protector for the M11X?

Why would you need that when the package already comes with the plastic screen protector?

Just extra protection to keep the dust off of it. I wonder If I can just buy a sheet of screen protector stuff and cut it to size.

Sweet, I just won an auction on a screen protector for an Ipad. $0.99 with free shipping. I figure it can't hurt.

regular m11 help

the centering/return spring snapped on my m11 yesterday. does anyone know if I can buy a new one?

Anyone converting from MT-4 to MX11? And why?

Actually, I shared my experience in the earlier part of the thread. Changed to M11X from the MT-4 was due to the speed and accuracy. The throttle response is much smoother and precise in the M11X compared to the MT-4. Despite the RX451R was binded in the NOR mode with the M11X and SHR mode in the MT-4, the throttle response is still better with the M11X. But no significant difference in steering response. The test was done before I sold the MT-4 and got myself an additional RX-451R receiver for my the other car.

The MT-4 is indeed a very decent controller for the basher and casual competitor, but if you're dead serious about RC, you will settle on nothing but the best i.e. the M11X. Those who insist that the MT-4 is as precise as the M11X is living in self denial.:lol:

I found this awesome screen protector on ebay a while back when I had an M11 & I thought I'd give it a try. Didn't actually have the M11 for very long so I used this protector on my M11x. Very satisfied with it, even comes with a handy micro-fibre cleaning/polishing cloth that works really well. Super easy to apply & seems thick enough that it should provide good protection for years. Only $9, bargain!

Just reading through the last few pages about Dual Rate vs EPA. First, set Dual Rate to 100%. Then adjust your EPA down just to where the steering servo does not bind left and right (Usually 70% left and right, for example). Now you can leave your EPA alone. You don't have to mess with EPA ever again unless if you move your arms forward or back or shorten or lengthen steering rods, etc., etc.. That now means 100% Dual Rate equals 100% steering throw without binding. If your car over steers, use your thumb knob to turn down your Dual Rate to 90%. Now you have 90% steering throw to the left and right. See if this corrects your over-steering problem. If not, try going down to 80% Dual Rate (which equals 80% steering left and right). If not, do a setup change on the car. It's pretty normal for people to setup their car with 90% steering throw (90% Dual Rate). Then they can go to 100% steering throw (100% Dual Rate) if they need a tad more steering, or dial it down (Via the thumb knob) to 80% steering throw (80% Dual Rate) if they need a tad less steering. This is the proper way to setup the cars Dual Rate and EPA. Of course, if you accidentally turn up your Dual Rate to 125%, you are going to bind up your servo.

A lot of people also have a panic button programed on their radios. They setup the car normally. Dual Rate 100% then EPA adjustment. They then turn down the Dual Rate to say.... 40% and setup the car from there. This means the steering will only have 40%. The wheel turns less, but this also means less binding in the turns. However, if they wreck, the car may not be able to turn around because the car only has 40% steering. They push the panic button which gives them 100% Dual Rate (100% Steering Throw). This lets them temporarily turn the car around at 100% steering until they release the button. And blah blah blah...

Hope this helps settle the confusion/debate.

What is this "thumb knob" you're talking about?

Nevermind, I found it. My fat thumb barely fits up in there though, haha.

Hi everyone
What should the screen look like when you have set up and

Sorry if this sounds silly (its my first top end radio)

There is an oft repeated saying "There are no bad questions, just bad answers". Well, that's not entirely true coz if someone asks 'I wonder, is today the day I will be able to dive into the molten lava in this volcano, swim 2 laps & live to tell the tale?' Clearly that is a stupid, moronic & bad question. But if someone is truly interested in learning about whatever it they're asking, then there can be no bad questions.

Anyhoo, in answer to yours, it's purely down to personal preference AFAIK. I have it set to the 'opening' screen, the one where the 'Sanwa M11' (why not M11x I have no idea, always been unhappy about that) logo & battery voltage & hours in use are displayed. I guess it depends on what info one wants to have available at a glance or if there are any settings which need to be changed often that would decide what screen people have showing while racing. I'm guessing most people would simply have it set on whatever was the last menu item they played around with.

Not sure if you're referring to 451 or 451R but I know for a fact that the 451 might be able to 'handle it' for a little while when used with a 2s LiPo but use that LiPo for long enough & it will eventually damage the Rx. I think the 451R is the same but not 100% sure. Someone even posted here just recently about their Rx getting fried coz they had been using an unregulated 2s LiPo.

New M11X drift spec. Notice the price lower left? Thats about $950!!!!!!

Cool, but why does it cost SO much?? Besides the colour of some bits being sorta brownish, what's the actual changes to performace of the radio? Apart from the way it looks, how is the M11x drift spec altered from a regular M11x?

Surprising how often people make this mistake. The end-points must be set on the racing surface because when on a stand, obviously there is no added friction from tire contact & therefor 100% steering will no longer be possible as the servo has added load & will not turn the wheels as far as when on the stand.

I agree 100% with the way you go about setting up your steering but I don't agree with some of your reasoning & the way you came to your conclusions. But the conclusions themselves, spot on. :nod:
E.G. Don't believe everything you read in the manual coz at times it is both misleading & misrepresenting regarding what the menu items actually do. Consider the following from p.25, regarding servo speed adjustment: "The POINT setting locates the actual point in the servo travel that you want to slow the servo's movement." No it doesn't! It sets the point in the servo travel where one wants the servo speed setting to actually be disengaged or not apply anymore. Well, that's for steering only (geez!). For brake servo speed point setting, it locates the actual point in the servo travel that the servo speed setting actually takes effect/starts working! That is the exact opposite of how it works for steering, yet the definitions are identical - CRAZY! Not to mention the fact they are both 100% incorrect anyway.

There are more like this in the manual but I'm sure you get my point. Also, even though I agree 100% that D/R should be set before EPA, your reasoning that D/R is higher in the menu structure is strange because both are higher/before the sub-trim setting & of course, sub-trim always has to be set before any other steering settings to make sure that the servo horn is as close to perfectly perpendicular with the servo as possible - or for throttle on 1/8th nitro, that the servo horn is as close to inline with the servo as possible.

Thank-you aaron 125 does your battery indicator flash all the time ??
(love the swim in the volcano)
Also found more makes sense the more you use it.

Will the 451-r work with savox servos on nor setting
