How do you know that for a fact? Because that is not my experience. And sure, someone can be unlucky, and have a faulty rx that can't handle lipo, but I know a lot who do use unregulated lipo in their 451 rx without any issues.

That was is the "correct" reasoning, because I still cannot see why I should set Dual Rate before EPA.

The reason to set D/R before EPA is so it can be used as originally intended (by the manufacturer, the end-user, etc.). The D/R sets the general sort of kinda overall amount of steering. It is intended to alter the steering throw/amount in relation to how much the wheel is turned. It's intended so that increasing D/R from any setting increases the overall steering servo travel equally for both directions. The opposite is of course true for decreasng D/R.

None of the above is true of EPA. If EPA is set before D/R, how can one increase their steering without binding & damaging the servos, because the EPA was set to the point just before the servos start to strain. Therefore any increase in D/R will result in servo strain & perhaps damage as well.

I can't really see why or how you could set the EPA before D/R unless you are not using D/R as intended by the manufacturer & as D/R has been used for many years, as a general sort of kinda overall amount of steering control. It really comes down to how you use it & if you use it as intended. It's not the most exact control there is, hence why it has such a meaningless name - what exactly is the duel referring to?

Regarding unregulated LiPo, I did mention that it might be ok for a while but eventually it will damage a 451(R) & that someone posted in this forum in the past week or so that they fried their 451/451R (can't remember which) by using it with an unregulated 2s LiPo. Both the 451 & 451R are specced for no greater than 6.0V. From the 451R instruction manual: "WARNING This receiver is NOT equipped with BEC circuitry. DO NOT use a receiver battery any greater than 6.0 volts to power the receiver. Use only a 4.8 volt to 6.0 volt receiver battery, an ESC with a BEC circuit that lowers the voltage to the receiver, or a voltage regulator that lowers the voltage to the receiver." Capitalisation & bold text as is, not my editing.

So for sure, it is possible to use a 2s LiPo but it definitely isn't advised & would 100% definitely not be covered under warranty when it eventually does fail. But how long it might take until it fails is anyone's guess.

I did that for my MT-4, I chose a glossy one. No problems at all. Actually, the screen is even better with the screen protector.

I guess we have to agree on disagreeing how to use it. I can't see how any of what you write goes against my way of doing this. Whether you set your EPA at D/R 62% or 100%, you can still fry your servos by turning up your D/R.

They started out writing that about 6v, but they have changed it. The first link is the Airtronics version of the 451, and the second one is the 451R.

Please notice this:

Not if your endpoints are set correctly.

I don't have my equipment by my side to check, but how is that? If you set your EPA at D/R 62% and then bump up your D/R 100%, then your EPAs aren't right anymore. Or how does it work? Because it might be here I get it wrong (unless it works like I think it does).

Go back and read my post on page 79. Now there are exceptions to everything and yes, even throw left to right can change when adjusting dual rates. There are givens to everything. But if your servo placement and horn placement and steering rod length and all that are setup correctly, then your endpoints will be the same left to right when setting that up. If that's the case, more likely than not, then when you are adjusting dualrates, it will be even left to right no matter what dualrate you set it to. However, if your left end point is 79 and your right endpoint is 88 when you are at 100% dualrate (at max steering throw without binding the servo), then yes, you need to slightly adjust endpoints when changing dualrate down from 100% to say.... 80%. But when you do readjust your endpoints, you should adjust the side that steers more to steer less. This way, when you turn your dualrate back to 100%, you won't bind the servo on that side.

I can see both your guys points. The important thing is to try and setup your servo placement, horn placement/angle, and rod length so that there is even EPA left and right. You'll see guys at the track setting up epa so that their cars make an even size circle turning left and right. This is a good thing to check on as well.

There is a lot involved, but for basics... I prefer the way I discussed on page 79. Once you understand the concepts, then you can alter things here and there. Blah blah blah... haha :lol:

Hey guys

I have had a STUPID moment and i have snapped the wire Antenna off one of my RX451's is there anywhere in Europe where i can order this from , i can only find them at Airtronics and i cannot order from there as they only ship to USA and Canada:(:(

You try the LRP Europe website? I think they do Sanwa stuff.

Dunno about buying the aerial wire in Europe, but I have seen the 451 aerial wire on the websites for some shops in Japan. I think that perhaps RCMushroom or RCMart or one of those big Hong Kong shops also have the aerial in their stock list.

Hope that helps.

Try here? Shoot them an email maybe? http://www.lrp.cc/en/products/sanwa/

We seem to agree actually. I usually set my EPA with D/R at 100, so when I dial down my steering with D/R, my EPAs still work. The thing I don't get, and what they are trying to "teach me", is to set D/R first and then EPA. Because as I see it, if I set my EPAs with D/R at 62% (fictional number) and then afterwards bump up my D/R, I can bind my servos.

What is the difference between setting my EPA with D/R at 100 and setting them with D/R at less? Of course I do have to turn down my EPA more, with D/R at 100, as I need to remove more steering throw to lose the binding. But other than that, I can't see the big difference, that invalidates "my" way of doing it. I don't say that the other way is wrong, and I'm not trying to convince people to use my way.

It's Dual, not Duel. Dual refers to two. Two in this case meaning Left and Right. There-fore, it adjusts both Left and Right by equal amounts. Hence the name Dual-Rate.

I see what you are saying. I think I'm getting mixed up on who's side who's is on? Who's on first? http://www.youtube.com/watch?v=sShMA85pv8M

Hey guys, I need a little help. I just picked up a M11 and am having some trouble.

I am running a Tekin RS and when I go to pair up with the ESC (you know, hold the two buttons, full throttle, neutral, full brake) and in neutral the tires are moving forward pretty good, applying what should be brakes is actually throttle and the throttle is brakes. Ive gone through the book, but am having a little trouble getting use to all the features of this radio. Can someone give me a hand?
