I am confusing myself again, sorry guys. So if i were to use an AS3X RX via the control board, the AS3X would be on the canards as well then?

If you drop the use of the Air Brake, i guess we could use a 6 channel RX?

[BenOzzy94]

It probably will do. The elevator and aileron out put from the RX will be fed I to the box and the box will just mix the canards to the elevons. So it'll probably all work as one fluid motion

[Evan D]

How are you seeing that a 4ch will do? Pg 10 of the manual says the blue box (MCBX) will do the mixing. The site says a minimum of 7. We don't know yet if this will have a new version of the MCB or the old MCBE. But none of the MCB's have mixing in them other than a retract sequencer.

So we need the normal 6...
throttle
Elevon
Elevon
Rudder
retracts
air brake

If the MCBe does the mixing why do we need 7? If not we have two canard servos doing pitch and roll so we need two channels, ?

Oh and reverse.... So 7 and the MCBe does the mixing.

[MAVFLIGHT75]

Looks really good...

MotionRC can you confirm if this is roughly 1/11 scale? If so, I will definitely get

in span 0.094

1/10.64?

So never bothering with the Gripen and only having a 64mm Rafale, working canards are a new thing to me.

I will be looking to use a Spektrum 8360T, how do i mix everything in and ensure the AS3X is working as needed?

If you go with the 8360T, you won't run out of channels. As far as I can tell from reading the manuals for the plane and for the ESC, the canards are mixed via the board. It seems the airbrake and reverse are separate leads that must be plugged into the empty channels on the RX, if so desired. Here's what connections you will need on the RX ................................
Throttle, aileron, elevator, rudder, gear, airbrake, reverse.
What needs to be seen and experimented with is the possibility of combining the airbrake with the reverse on the same channel. IE, flip the switch for reverse and the motor reverses and the airbrake goes up. However, this may be undesirable. Eg. On the Eflite SU-30, FMS SU27, the dorsal airbrake is said to provide flight stability during the landing approach, so it's best to have it on a separate channel so it can be used prior to touchdown. Personally, I would not link the two (airbrake and reverse). So, if you decide to go with a Spektrum AS3X 6-ch RX, then you will have to eliminate one or the other.
If you have some experience with Spektrum smart RXs, you may ask ........................... "But reverse on Eflite planes don't need a unused port on the RX because the smart ESC doesn't have a separate lead to activate reverse, so why do I need another channel?" Well, that answer is hidden in the part about the "smart" ESC/smart RX. On Spektrum's low channel RXs, they still use a higher channel for reverse, typically ch-7 but that signal goes through a feedback signal on the throttle lead. It still uses ch-7 but there's just no port for it. Even their 4-ch smart RXs monitor and send signals thru channels 7 to 9. Those signals feed back via channel 1 (NOT SBus). If you use an 8 channel smart RX for reverse on a smart ESC, the channel you use for reverse (ch-7) cannot be occupied because it's an actual physical port. The HobbyWing reverse uses an actual lead. It can be considered a "dumb" ESC vs the Spektrum "smart" ones.
Insofar as using a gyro, be it a stand alone or a smart AS3X RX, that gyro acts via the leads going out of the RX or the gyro (stand alone gyros install immediately after the RX). Thus, any gyro controls go through those leads before the "board". The board does all the mixing and it is likely that if the elevons are gyro affected, the canards will also be affected in both AIL and ELE control.

PS. Don't let the part in the ESC manual for this plane confuse you. It says something about 0-50% does this and 50-100% does that. Just make sure you put it on a switch that goes from -100 to +100 (Spektrum) when you throw the switch. The other stuff about % is mostly for those using non-Spektrum where the actual numbers are different. They just want you to know that forward is the first 1/2 of the switch's throw and reverse is the second 1/2 of the switch's throw.

PPS. The Gripen may not be a good example as its canards are not mixed in a "board". I don't know about the 64mm Rafale. However, my 80mm Rafale does do canard mixing via a board but only for elevator response.

FYI, pre-order for this plane just opened at RCC, however, the shipping will be a killer, especially for US customers who get free shipping from Motion. However, you could get it by end of January. For me (Canada), the final price will be very close (using USPS).

[MeyerVW]

Sweet. I have been after one of these Eurofighters for a long time. Bad timing as I am moving but I will preorder one. I then have all the rc aircraft I need and time to start saving for a real ultralight. Thanks for the new release.

[DODGEBOY71]

I guess this one is not thrust vectoring like the last two?

[Evan D]

No. Totally new aircraft and no TV.

[Nyuhasz]

Any idea how the 2x 4S 6000mAh Admiral batteries are to fit in the battery compartment for the 8S High Performance setup? Battery Compartment => L=180 W=70 H=55 ----- 4S batt => L=160 W=46 H=40. The 6S +2S setup looks doable, but only with 5000mAh batteries aka limited flight time.

Thanks

You have the measurements right there, so the "idea" is in print. Looks like some foam carving will be needed for those batteries. I'll go with the 6000mah, 6s and 6000mah, 2s HRBs like I do in my other 8s jets. I'll also use twin 6000mah, 4s HV Coddars, which are very small and compact.

[Pete914]

So stoked on this plane! So much innovation: reverse thrust! Spring loaded cheaters! Full armament!! Gear door retraction option for grass ops! Airbrake??!!!! DUDE!

I pulled the trigger on the 6s b/c I have a lot of 6s packs. I like long flight times though...should I have gone 8s? I have a few 7s 5000 packs that I thought might get me better flight times but lightweight goes a long way with these foam planes. I wonder if the 6s motor could handle 7s maxxed out at 80% throttle?

I love that the B-2 is so efficient. That jet is a game changer....

GOOD WORK MOTIONRC AND FREEWING! KEEP THEM COMING!!!!!

[Evan D]

A lot of that innovation has been around quite a long time. Just on other FW planes spring loaded cheaters came out on their F-104 (bought my first one 8/16), Armament full set with the F-16 (bought mine 2/15), gear door retraction the way it is here has been on all planes with the MCBe controller, came out in about 2018, but others had it earlier like on the FMS P-51, Airbrake(s) well the F-104 has them but so do others. Reverse is now becoming common and a lot of us have been saying it's about time FW gets ESCs to do it, especially since they use HW ESCs.

But it's the package and this plane has the package. B-2, that is innovation, as you say a game changer. But then so are the Gripen and MiG-29 with not only TV but optional as an add on TV! So were the 90mm TV'ed Eurofighter and F/A-18E way way back then (As eRC in very early 2010) and the 80mm planes when they came out, the 8S ones when they came out, The F-104 was crazy innovative. Yeah, Free Wing is the leader.

This is why FW and Motion keep me as a customer. Awesome planes, awesome support, awesome service.

About 6, 7 or 8S. The 6S fan is new and not a known item. It's a smaller diameter, higher kV than other motors used in 12b 90mm fans. A motor with more mass and or lower kV may tolerate an additional cell or even two. Have to wait and see on this one. Of course, you need to be cautious of ESC and/ or BEC max voltages but if Tom is right and this has the 120HV that's not an issue. Really if you do want more power a more efficient fan or a matched system for higher voltage is the better way to go. I also got the 6S as it's specs say it should be a good match. If not, I have a couple JF/HET set ups I could choose from, a 1500 and a 1680, and since it appears to already have an 8S ESC it would be an easy swap.

Run a 6S motor on 7S at max 80% throttle is asking for trouble. First I bet it would be hard to not give it 100 unless you did a mix or limited it in your transmitter and then "what if" Also an ESC works easiest at zero and full throttle. The FETs work much harder at high partial throttle. Not to say the HW can't handle that but use caution with this thinking.

[Pete914]

I probably should have gone 8s. I wonder if I can change the pre-order.
I hear you a lot of these things have already been done but then you stated the point I was making: this incorporates all of them into one Jet. Also, any of the stuff from 2010 era was just so much less reliable IMO. Cheaper foam, cheaper electronics, etc.
The quality has really come a long way.
It wasn't uncommon to have to immediately replace stuff just to get the jet in the air.
Now, we have awesome customer support and planes that legit feel like they are developed by people that fly them and want to fly the snot out of them.
B-2 is a good example of this "level up" mentality on design and delivery

I'm not saying anything is perfect, but we are in a much better place now than in 2012

[Evan D]

Pretty sure they will ask you to cancel and reorder. Ask Tom, on here, he's one of the owners of Motion. Caution too as between us and Motion EU there are some versions sold out already.

I could be wrong but I've always had to cancel an order and then reorder what I wanted, you must have done what I have done in the past and get so excited and push that magic buy button and then start thinking about it afterwards, I don't preorder anymore, I just can't take it knowing I paid for something and have to wait a couple of months to get it..........

[Tomling31]

Really pleased to see the Typhoon is coming back, Does anyone know if this will be produced in ARTF- Plus? I'd rather go 8s in this like other models but I use HRB 6000 packs. Flying off grass without trailing link suspension may not be a good plan with the extra weight. A nice Schubeler 6s motor set up could be the best option, lighter but with decent thrust and efficiency. Can't wait to get one of these in the air.

[Evan D]

Kit +, 6S and 8S…

I'm not understanding why the brand of battery you use would dictate the desire for the ARF+ vs the 8s PNP. For what it would cost you to buy the EDF and ESC to put into an ARF, you would save so much money just getting the 8s PNP. Or am I missing something? The "extra weight" will only be from the battery weight of 8s, which may only be 300g to 400g. And since HRBs (which I plan to use) are lighter batteries to begin with, the added weight may be even less. Also note that the retracts/struts on this plane is more beefy than those that came on the original versions of the Eurofighter. Nevertheless, trailing link mains might be a better option for some pilots and I'm sure they can be adapted to this plane without too much work.
