- เผยแพร่เมื่อ 7 ก.พ. 2021
- This is the maiden flight video of the Eachine Razor. I test both stabilization and return to home of the Eachine FC in this video. This is very simple flight controller with NO settings options other than radio calibration, board level, and battery voltage. No pots, no gains, no reversing.
Watch the video to see how things worked out!

Nice job John.
It's never nice to see something not work correctly, but is is nice to see how it should be handled.
Jim is going to enjoy it.
We hear about RTH flyaways all the time and I harp on it. I test RTH over and over and over and......
The key I think is to make a decision. I'll have a story for the Livestream Friday on this.
That looks like it was effortless. I can't wait to try mine. Great video John :)
This is a very easy going plane. Easy launch, easy land...everything was easy.
Hey my RC brother. Great to hear from you Sir. Thanks for sharing this great video with us Captain 🧑✈️. Man you are very good at what you do man. You have a Big Fan and a Big Supporter here dude. I’ve been watching and supporting your videos for a while. Keep up the good work. Thanks for all you do and please keep flying.
Very kind comments. Thank you for watching.
@@RCVideoReviews You are welcome my brother. Much love and respect my dude. Keep up the good work Sir. Thanks for all you do and please keep flying.
Looks like it's a happy flier 👍
Yup, cool like the other side of the pillow ;)
Very nice review. Looks like a keeper.
I agree, very nice little plane.
seems like a nice little fpv plane..thx john!.
It is a little cupcake of a plane. Very very easy to fly.
Another great video. I have an FrSky stabilizer I'm anxious to try now. Thx.
This was a gentle little plane to fly. Maybe the easiest I've ever flown.
Cool going to have to get one
I came away impressed with this plane. Very easy to assemble, docile flight characteristics, and it has some skill with stabilization. It's a solid combination.
I have this Eachine Razor and my tip is; every time before you take off calibrate the GPS (sticks under/ outwards) till the ailerons and 3 beeps give you the information the Eachine Razor has locked on to the GPS satellites. Do this every time even when you change out the battery off the plane!!!!. If you don't do this your in for a nasty surprise if you switch to return to home!!!. PS i know because it happened to me and there was not much left of the plane. I have bought a new one and because i calibrate the GPS every flight i haven't crashed the Eachine Razor again.
We all need one of these. To be happy!
Yes, this is a low-stress plane I think. Very easy to fly and very calming. It just kind of coasts with no drama at all.
Dang I missed it. Glad it went well!
@@permanentlygrounded7770 This wasn't a livestream, so technically you didn't miss it ;) Yes, this is a super easy going plane.
A bit closer would it be better, but nice clouds !!!!
Great review I agree with maybe no lock on GPS some do it right away some take a little more time great response on shutting off RTH and how easy it was to recover
Take Care John
I'm sure that was it because we were talking about the launch assist and after I plugged in I realized I had the GPS puck upside down on the bench. But since I had a helper, I just buttoned it up and had him chuck it. The first flight GPS locked and performed perfectly. Good lesson to catch on video.
Was anxious to see your results. I bought one of these and commented on your live build about the lousy stabilizer setup info and feeling like mine was going to fly away. My circumstances were a bit different than yours, I did a manual launch on the second flight and when I hit the RTH mode the plane continued away from me WAY out of my comfort zone. It was a gray day, and a small white plane starts disappearing pretty quick. I *hope* it was a GPS lock issue like you experienced, I haven't hand a chance to try it again. I did verify the flight controller LED's on the bench indicating all the modes were working correctly.
My first flight had RTH work fine. The second flight I didn't verify GPS lock and I know I powered it with the GPS puck upside down on the bench. RTH should be repeatedly tested until you are 100% comfortable with the results.
I ordered it last night, FPV version, I am beginner, I feel this might be too much for me... but I will give it a try, thanks for the review
@@jimsnodgrass8454 yeah I will be making my own liOn pack, where is the CG? BTW very much thank you for your videos, next time I order something will use your banggood links.. I have learnt a ton from your videos, especially the OPENTX ones, your editing and narration is extremely clear, precise and to the point
Just take it one step at a time. First: Fly the plane. Make sure it flies the way it should. Second: Test stab and RTH. Make sure they work the way they should. TEST TEST TEST. Finally: Add video. Make sure it works the way it should by having someone else go on goggles while you fly the plane. When you're satisfied the video works and all the prior steps work, then go on goggles.
I just got my Razor delivered. A complete noob to RC flight. What's the deal with the camera that came with it? What do I need to add to actually see or record the video?
👍👍 for Johnny
Johnny's 'da man.
7:05... I would do the test again with GPS Lock.. At this point all we know for sure is the RTH works when you do not use Auto Launch.. Looks like a nice stable flyer.
I'm confident the reason is because it didn't have a lock. When I set this one up, I had the puck upside down on the bench and didn't think much of it. In any event, the plane is broken down and in a box on the way to the next owner.
Hey just picked one up and after assembling my elevator is pointing up a few degrees. Curious if you would recommend setting and offset in the mixer, sub trimming in output, or some how change it hardware wise in neutral position
It's always better to start with your surfaces centered mechanically. You can use radio options, but you usually give something up like resolution or travel. If you can center it with the servos on and centered, do that.
what helmet/hat cam are u using john?.video looks pretty good.
That's just a GoPro Hero 5 Black.
Did you fly it with Li-Ion battery? I found that it draws way more than 5 A on a full throttle - which causes battery internal controller to trigger overcurrent protection... Or - no BMC, no problem?
My LION packs don't have protection circuits. My Samsung 25R cells are rated to 20a. Plus, I gave this away.
Hi John. Great review (as always). I wonder if you could help me with one thing. I have a spare ZOHD Kopilot lite around (3 in use already) I wonder if it could be used for an ICE plane (either Nitro or Petrol) The plane is standard 4 channel AETR. I am bit worried about throttle operating by Kopilot...
Thanks a million !!
I don't see why not. I'm not familiar with the intricacies of throttle trim for ICE planes, so you'll want to verify that operation, but as far as I know, the Kopilot never moved throttle below 50% in RTH mode during my testing. I don't see why it wouldn't work.
@@RCVideoReviews I was thinking about it for a while and I can see 2 possible options.
1: have the pwm channel 3 disconnected from the KP and have the servo connected directly to the RX.
2 use it with KP and let it control the throttle, but it might be tricky do the trims for the throttle so it operates just between the minimum open carburettor and full open.
Hi, on your live build video you encountered difficulty configuring the flight controller can you explain how you overcame this problem. Thanks from stormy, freezing U.K.
Somebody's not joining (or watching later) the weekly PilotJam... :o I reversed the elevator servo and it calibrated perfectly. th-cam.com/video/bvTtQBbj5V4/w-d-xo.html
@@RCVideoReviews I found it thanks, your right I should have found it but exhausted watching your excellent snippets on the Radiomaster 😂 Pretty lame excuse I know👍
@@michaelwheatland4565 Thanks for watching. Once I flipped the elevator it worked flawlessly.
the PNP version comes with GPS and FC?
Yes...
RE that flying too far away before turning at auto launch. I believe it was working correctly. You can't spin up the motor in Stabilize or RTH without the GPS locked. (Though I'd give it a few extra seconds to crank the tally up a bit from the usual minimum 6/7 ;-) )
What catches many folks out is the behaviour of Kopilot (it seems this is a variation of the original unit) near the ground. At auto launch (or on RTH) if the plane is under 35m above the height the barometer senses at boot up, Kopilot sets the plane to fly out straight and level at a steady climb until it reaches 35m and only then does it start to turn for home, continues to climb up to 70m, returns and circles home. Lots of "It just flew away!" :( "But then it came back!" :)
Seems a pretty good plane but with our propensity to stuff things into the landscape, lighties like the Volante/Eachine V761 minis and pushers or wings like my AR Mini seem more suitable for us geriatrics. :D
The GPS wasn't locked. On the launch it headed South, on the subsequent attempt it headed East. On the first flight it turned West at the flight line. It definitely did not have a lock.
@@RCVideoReviews Fair enough John. You wouldn't consider doing a comparison of the behaviour of the flight controller in this and the ZOHD Kopilot would you?
@@theoztreecrasher2647 I've already torn this plane down for shipment to the new owner. They're almost identical in operation though. The biggest difference is the Eachine unit has no adjustments. Literally.
@@RCVideoReviews Thanks for the reply. I suppose we could ask Andrew Newton. He seems to have liked and kept his. And no accent either! 😜😊
I like the plane. One of our subs lost his so I’m trying to help him out by replacing it for him.
ide be happy if you could send me some green grass and warm weather like that
It's just now getting warm. It was freezing this AM. It got all the day down to 56°!
@@RCVideoReviews lol come on that's summer temps here lol
