E-flite Viper 70mm EDF Battery, Radio, SAFE Select Setup Hints & Tips

[@ajgerbair]

Finally, thank you for explaining perfectly well how to set up safe. Having gone from Dx6i prehistoric (dsm2) via Futaba (good radio, no doubt) to a brand new Dx9 black edition (yeah baby), I found it hard to get it from the manual. I am an user and you managed it to explain to a dummy like me, so thanks! Keep up the good work Horizon!

[@random_g-man9754]

Thanks. Was working with a DX8 and couldn’t figure out why safe select wasn’t working. But this video helped sort it out.

[@gmax876]

I do like the idea of safe bound to the landing gear.

[@rgeller56]

Got everything working except for I can't get the safe select switch to activate Dx8

[@BobK-NH]

Thanks for the great instructional video, Jason. As an owner of a DX6e, it was very pertinent. Not sure I’m quite ready to graduate to an EDF yet, but this warbird. with SAFE SELECT is the way to go!

[@MclF01]

soz mate its not a warbird .you shouldn't rely on safe if you want to move to the next step

[@BobK-NH]

MclF01 Yes stand corrected not a warbird. But I can’t afford replacing $250 planes while learning to fly them so Safe Select can save the plane and let me fly another day.

[@MclF01]

safe is ok but you shouldn't rely on it.and that will not give you the conderfance to fly $250 for you but close to $500 aud for me .. my advise if ur learning don't buy expensive ones

[@brianchambers1515]

It's videos like this that make you guys top notch thank you for sharing

[@spanzer6179]

When you were setting the flaps movement number 0 position was a 100, position 2 was -65. Why was position 1 Positive 45? Wouldn't that be flap moving up?

[@leerenslear1064]

servos are at zero degrees with power on and no input-----full travel up or down is either 100 positive or 100 negative----set up called for reversing flap setting...so with plane level , flaps are 100% positive using a maintained 3 position switch , in position 0. flaps up ....... using switch in 1 position the number suggested is 45 positive--- you could pick any setting you like 45+ or 45- just depends on how far you wish your takeoff flaps to travel...the farther you head to a negative number,the farther the flaps will descend down....or a higher positive number,say55 will raise them higher for less flap travel.... landing flaps call for numbers to go past 0 into a negative value,their recommendation was neg.65...you could go full down position which would be negative 100......and because you are using a switch it maintains its position and stays at your switch position settings....hope this helps.....

[@edward24dupont]

Thank you, you just answered a question I was going to ask you. I noticed a little up elevator on throttling up. Thank you for explaining that.

[@HarryBunnGRVOTV]

You keep banging on about ec3 & ec5 connectors and adapters. The advice you should give is to solder on your own connector to match your batteries! Having multiple connections is just more points of failure.

[@MclF01]

or have options like FMS gives you .i like how they say we recommend this lipo but u need to cut some foam to make it fit and it will make it abit nose heavy ..??? im laughing alot when i heard that ...well i recommend you fire the person who approved that . anyway its the FMS viper just repainted eflight electrics i just think its to cheap for eflite to have that cheap retracts....turn safe off

[@scottfirman]

Not everyone has a soldering gun. It is easier to order a connector than soldering on thicker wires. I mysrlf use a butane torch. It gets much hotter and works faster on a connector and has less chance of damage because it works so much faster.

[@jriley1974]

The point is that the EC5 connector better handles the higher current than the EC3. Also, the supplied esc has the EC5.

[@RCSafari]

I like the safe - and I like the price point! Nice entry level Jet - I'll take 2 please!

[@GBLynden]

RC Safari Did you end up getting one? :) I did and I love it!

[@contrains1264]

My safe won't go to flaps switch?

[@jimmy90113]

Safe select is reversed for me, when the flaps are up safe select is on, down off. I've tried reversing the gears. Are there any fixes for this?

[@src2920]

Hi Jimmy, Same issue here. Could you solve it?

[@gpaje]

Yes, you will need to install a servo reverser on the 5 channel and then plug in the servo leads to that.

[@rogersnow1036]

How to set up a safe switch on the nx8. I have safe all the time. I tried pushing both sticks in and down. And flip switch 5 times. But it still has safe all the time

[@miguelmartin1157]

I have eflite viper 70. and station DX6. the station brings an Aux2 that I have enabled but it does not move in channels. I have enabled a switch to the auxiliary2 to connect and disconnect the stabilization, and although I follow the steps of joining the Stick to the center and moving the assigned switch 5 times, the stabilization is not interrupted. What should I do?

[@deppi]

Can you set up so flaps and retracts are same channel ? So safe can still be assigned on a seperate channel??

[@HorizonHobbyProducts]

No, because the flaps will go up when the gear go down and vice versa (which is the opposite of what you would want). If you only have a 6-channel transmitter, your only option is to combine flaps and SAFE as shown in this video. This is why we recommend 7-8+ channel transmitters for most of our models now.

[@maskog]

Hello Jason, I’m not sure if you actually do look at this comments but if you do, I want to say many thanks for explaining how to setup this viper 70 so well. I have a question for you, any idea why my viper 70 after I rebuild it from a crash, will now take off and immediately roll over even with safe mode on. Any suggestion is welcome. Thanks again for all your very detail description you have made and I’ve seen them all. You rock.

[@steven198130]

when u bind the plane with safe select its automatically in safe mode but if u wanna turn it off u to assign a switch is that what ur saying

[@Chayseangus]

what happens if you dont use the flap switch wound it not work?

[@contrains1264]

Why can't you use the other switches for safe select

[@HorizonHobbyProducts]

If you have a 7+ channel transmitter you can assign SAFE Select to a separate channel (from 7-9) and switch! You only need to combine it with the flap channel/switch if you have a 6-channel transmitter.

[@TangyLlama]

Is it possible to just have safe on at all times without using a switch on your transmitter. I have a dx6e so that’s why

[@TitaniumRaceTeam]

Hi I was just wondering I have t-50 black eagle I am trying to set up on dx7 if you be able to help me I really appreciate thank you

[@dougrymer4490]

I just bought the viper and a new NX8. The manual for transmitter setup does not include the NX series. What are the setup preferences for the NX transmitters?

[@cG-es8mb]

Why did you have to reverse flaps?

[@65Max]

Does the Viper receiver respond to Forward Programming? Probably not since I didn't see that menu option after binding SAFE. However, installing an AR630 will add a 7th Aux2 Channel on binding and activate Forward Programming.

[@HorizonHobbyProducts]

The original BNF Basic version of the Viper 70mm (EFL7750) included an AR636 receiver that was NOT forward programming compatible. The current BNF Basic version (EFL77500) includes an AR631 receiver that IS forward programming compatible: www.horizonhobby.com/product/viper-70mm-edf-jet-bnf-basic-with-as3x-and-safe-select-1100mm/EFL77500.html

[@jamesbottazzi7199]

I have freewing f 16 edf should I do that aileron

[@src2920]

Hi, I was trying to the same thing with my AT-6 but SAFE was ON when gear up or FLAPs up. However, this works for Viper. Why so?

[@husaberg12]

I only have the old dx6i right now,can I not assign safe to a switch and just bind it with safe always on🙂

[@1stMarine]

Great video Jason, well done :-)

[@aurelioarenas6293]

Cannot have the same results on the P51. By reversing flaps my D switch works in reverse, meaning switch down flaps up and vice versa, to fix that I have to set up flaps to negative, on top of that Safe in on with flaps up. Don't understand why having tha same radio but different plane things don't work. Any suggestions?

[@HorizonHobbyProducts]

After you reverse the channel for flaps again, change the values in the Flap System menu to get the flaps to go the other way for a given switch position. For example, you can change 100 to -100 (or -100 to 100) so the flaps are up instead of down (or down instead of up) with the D switch in the same position. After you do this SAFE Select should be on when the flaps are down instead of up :)

[@theo52ful]

hello from Belgium. Great your videos! I have a question for you... I have a Spectrum DX6 NGénération and a viper edf e flite 90 mm in bnf. I would like to use a switch for safe select .could you give me the procedure to follow? thank you very much, Thierry...I tried as it says on the manual, but the plane still remains in as3x mode of in safe select !

[@HorizonHobbyProducts]

Hello Thierry! As explained in this video for the 70mm model, if you only have a 6-channel transmitter you will need to combine the SAFE Select function with the flap channel/function. You need at least at 7-channel transmitter to have SAFE Select on a separate channel/switch (because you need to use channel 5 for the retracts and channel 6 for the flaps).

[@thierrylecomte4711]

@@HorizonHobbyProducts 👍thank you very match

[@theo52ful]

@@HorizonHobbyProducts Hello friends. I understood your explanations on this subject, but the problem encountered is different.when I have assigned the safe to switch D, the opposite effect occurs; flaps out is the as3x and flaps returned it's the safe activated. What can I do in this case?. Thank you again for your kindness friend

[@merv888]

Can I assign safe to half flaps instead of full flaps?

[@DanielvsBabylon]

Can I use my DXS?

[@JoeSmoe1]

wait, doesn't the DX6e have a flight mode switch? separate from the other 6 channels and throttle cut, so safe can be assigned?

[@JoeSmoe1]

@Jason Moreau ty man

[@joshuagriffin5144]

When your not using flaps u can u safe

[@rogerw65]

Viper is bound in safe select mode to the DX6 but only works in ASX mode. What is wrong? Do I need to reprogram the AR636 receiver?

[@rogerw65]

Problem solved

[@lw216316]

So to activate AS3X do you blip the throttle like we have to do on some other models ?

[@mrparamedico25]

Can you do the same and does it work for the spektrumDX8 too?

[@toby1444]

Is the best location for the RX antenna under the timber battery frame? what do you recommend?

[@mgislao7]

Ok, question. If you are using the 7 or 8th channel from a DX8 for SAFE, is the included 6 channel adequate or do I need to replace with a 8 ch receiver? Thanks!

[@svenmontag2576]

Hallo und Grüße aus Deutschland Wird das mit dem Fahrwerk unten und Safe On bald möglich sein ? Das wäre für mich die beste Lösung, da bei starkem Wind Flaps nicht wirklich hilfreich sind ! (DX6 Steuerung) MFG Sven.

[@irwinwka]

Jason, great video. I’ve watched it numerous times and have my 70mm viper set up with safe on flaps.. I think I know the answer to my question. I have a 90 mm viper and am doing the same thing, safe on flaps. Should be the same. Right?

[@grninerc]

I am certainly quite interested in checking one of these out, I would agree with RC Hobbyist Extreme when choosing a higher C rating lipo for a EDF. 40 or 50C would be more ideal. 30C would Puff quickly and I would not recommend it.

[@billshepard2908]

Are XT60 connectors suitable for use on this jet?

[@GBLynden]

Bill Shepard Hi Bill! They are not.

[@billshepard2908]

Thanks buddy! Got the new Viper and have 6s 4000's 60C on the way with EC5 Connectors !@@GBLynden

[@joshuagriffin5144]

Yes of course they are

[@eugene876]

Please got new jumper T18. Came with no instructions. My first transmitter. Can't get wheels down or flaps up viper jet 70 mm BNF \Safe Selleck

[@mohammadarman7577]

Sir I want to become rc plane having 2kg weight I will use edf 70mm- 6s motor then tell me which is suitable battery for this rc plane mAh??? C??? For flight time 10-15min Please reply me sir I request you

[@nevTk-oe9ud]

Has this receiver have telemetry ?

[@scottfirman]

If it is the same as mine, yes.

[@nevTk-oe9ud]

which one you have m8?

[@rctanksmasher563]

Is it possible to fly it with an DXe?

[@JasonHunts2772]

Yeah it is but you can’t use the landing gear or flaps don’t give it a shot I already have a it’s not good

[@bperfect1057]

Very nice

[@mako2350]

I havent flown RC airplanes in 2 decades, I used to fly pattern ships and pylon racers. Now I fly RC Helo's have a Blade 230S, But this plane looks REALLY cool and has better flight chars than normal Jets I have seen. I only have a DX6 radio. SO will have to debate on the radio upgrade, I do however like the flaps tied to the Safe Select... so good call for 6 chan radio owners... I may buy own, my only hang up is that I am NOT a fan of foam planes.... So I don't know.

[@Duderocks5539]

Can you by chance install a panic button on a DX6E or another transmitter and use it with this? I don’t the need SAFE features as I am already experienced ,but I would like to have the panic button just in case.

[@GBLynden]

Duderocks5539 SAFE is basically a panic button on a switch.

[@keithrobinson870]

I would mix safe to the landing gear so it's on for take off and landing even if I don't use the flaps

[@random_g-man9754]

Can I hand launch this?

[@GBLynden]

Whizzpop RC I wouldn't, it does have a lot of power though 😀

[@CalebT_RC]

Could you guys do a Ka-8 sailplane please

[@serratoanthony]

Is this a good first plane?

[@tonysilveira30]

I'd buy this if it to a 5000mah battery cause I have a bunch of those. Also I wouldn't recommend your eflite batteries the c rating is to low for an edf. Those 3200 30c will puff quick

[@jamesbottazzi7199]

Need help

[@scottfirman]

Time to stop including the Dx6i on newer planes. I wouldnt even buy a 6 channel transmitter any more. The DX 9 seems to be the best bang for the buck. Everyone that has a DX 6 usually finds out quickly they wish they had bought the DX 9. I did .

[@billshepard2908]

Great cost saving advice sir.
