- Опубликовано: 3 июн 2024
- This is one of the most beautiful rc planes of this size I've encountered in Banggood, but it didn't go as planed, maybe it was some minor details I didn't notice but after few crashes, I decided that I spent too much time already and gave up.
This is a beautiful replica of a Savage Bobber ultralight.

This is not the only review of this model having the exact problems, manufacturer needs to to figure it out and fix it , what a shame it is a good looking model.
100% and it's too expensive for what it is in my opinion, which is a shame because it's a great looking plane!
You need to set the motor a little to write a little down so it doesn't roll to the left
@@grahambate3384probably a prop with less pitch too.
Bummer that she didn't fly well for you as well as many others, too! I saw one at a local field and asked to pick her up with the flight pack installed. Ultimately, what makes the full-scale Bobber fly so well is how LIGHT it is. This RC version is the heaviest flight ready 1 meter of it's kind we've ever seen. When you have a high wing loading, your wing is always going to be much closer to a critical angle of attack while struggling to keep itself flying. Any slight increase in back pressure/up elevator will lead to one or both of the wings reaching the critical angle of attack (stall), as you experienced. Bottom line, it seems the best plan of attack is to simply not pull the trigger on this plane, which is unfortunate because it definitely is a looker!
Looks to me like it's a wing washout issue. You need to twist the wings so the front tips are slightly down 1 - 2 degrees from the root. This prevent the outside of the wing from stalling before the inside if the wing.
Agreed. And then he still has to not stall the aircraft.
Washout helps with where the wing stalls first, sure, but ultimately this plane is abnormally heavy for its size. The wing loading is through the roof. Even washout won't help prevent it entirely from always flying around super close to a critical AOA due to a very highly loaded wing.
I flew mine too yesterday. Without problems.
Your CoG is so wrong.
Visually it looks like a 3S battery. In conjunction with a 20A regulator, I find that optimistic.
In addition, the battery is far too far behind. The result is tip stol.
Tip from me: 2S 1500mAh directly behind the motor in the shaft provided for it.
Video of my first flight is coming soon.
It’s easy to forget that flying ain’t easy! Everything has to be right to fly, but only one thing wrong to crash.
I had a kK Invader which I converted to rc powered flight. It was an ugly duckling, but slowly, with each tinker, it got better. One day I realized I finally had a great little aeroplane.
I know how you feel though, there are some aeroplanes to which we never get attached.
Looking forward to your next project.
Next one is autonomous plane using Ardupilot
Thank you so much for this video! It saved me a lot of money and heartache!
Please make a video on "How to build DIY Helicopter" in the same way you taught Foam board Rc Airplane which was amazing. Thanks a lot.
Yaaaaay! Another joyplane video. He needs to make more of his foam board designs please
More to come!
You just save me from a bad purchase, thanks mate
Hi! It reminds me a sbach 342 i've assembled a while ago for a friend, similar wingspan and same color combination and construction method (plywood, lot of steel -even a push-pull wire for the rudder- crazy ha?) didn't seem it to you too heavy? I would bet the wing loading is on the high side!
My father and I has same type of plane. Big body but short length. We found that CG should be more forward than typical plane. And it needs more speed to more run to take off. Landing these are always been tough imo.
This plane not stable, patricini bros also crash on maiden flight with this plane.
hm, did you use the same esc the second time?
if it's so bad, that it desoldered the wires, it might also not supply enough voltage to the BEC under power, making the reciever brown out or the servos move uncontrollably
I used another one
I built the same from 3D Plane print, flies quite well.... print new if crashed.
What is the guitar tune?
Wondering if the wings had a twist in one of them. Being wood and film covered, this could easily happen in building, or during shipping if exposed to wide temperature range.
During all the video incidents, the Savage Bobber was consistently bobbing to left, 100% of time.
If still have wings, you might try sighting down the leading and training edger from the root.
Another possibility is the motor/prop combination and torque having an effect (but less likely IMO).
I Love the look of this bush plane, but i don't have the flying experience to try build and fly, I can see this happening for sure if I did, this video helped me to see what can go wrong. Sorry for the accident and thanks for sharing.
I tried to build a piper cub plane a while ago, and because the wings were to much angelt up like a v it also stalled out the whole time. Than I made the wings flat and now it flies perfect, maybe this ist the problem.
I don't think I'll try again, I'll invest the time on a new long range autonomous plane.
I still haven't found a video of this Savage bobber model flying properly. Everyone has the same issues you're having(or had). It's time for the manufacturer to do something. Dancing Wing
@@TugIronChief ya, thats what im hearing...Its such a good looking plane, I think you can buy it without servos, esc, motor.
I am having the same roll to the left on take off. Very annoying.
if i see you have the rc commands set incorrectly
Wow. Sad. It looked so beautiful too. I wonder what was the problem? Well hopefully when you have time you will figure it out and get it flying. Thanks for sharing. Cheers.
Great
Can you tell me what propeller i should use on a 2700kv motor running on 2s battery please tell me 🙂
7”
@@Minusliquid16 7x what pls tell😥
I wonder You assembly parts F10 upside down. Then thrust line face wrong direction. In this case, we Japanese avoid trouble by using an asymmetrical key slot.
Wow never seen ESC wires in-Solder. She looks great, such a shame she had huge issues.
I agree, very strange stuff
I think your over control 😉
Pleased I’ve seen this, as I was tempted to buy one. Not now.
I reckon your wings are warped and you’re getting the effect of aileron turn. Also I agree with other comments about weight. For an open structure film covered model it’s surprisingly heavy. VMC Super Cub is a much better model (same span, lighter and forgiving to fly with oversized wheels).
Looks like it's a Dancing wings kit, they do a balsa kit self build, the cabin is exactly the same, the fuse is carbon tubes rather than the 3d printing in this one the self build looks a better option this kit was not factory made well
Bamooo nuevo video
Thats the first time I see a model that crashes right out of the box LOL
Yes, there's always a first time.
The angle of the motor must be right point down and to the right
oye esta muy interesante ese avioncito !! creo que comprare uno jeje un saludo desde megacontroltv !!!
oo ahi vi que se te estrelló al aterrizar!! :O creo que fue un viento cruzado .. es pequeño así que hay que volar con "0" viento o mínimo viento
Me han dicho que la batería que use era muy grande, yo recomendaría entonces una de 1000 mah 3S para ahorrar peso.
@@Joyplanes claro es probable .. mm est video tiene version en español? para escuchar tu relato bien jeje mi English is no good jajaja
I think the left wing has the wrong direction washout. It looks truly gorgeous so it’s a shame it flies so bad.
Why you use such a big battery? We officially suggest to fly it @2S 1300-1500mAh.

Looked to me like you had a stabilized receiver in wind rejection mode that was causing the problem (it was rolling the plane the wrong way).
I don't use stabilazed receivers, I normally fly manually.
Thanks for the warning. Like the looks of the plane but not the way it flys.
Initial crash I felt like the thurst angle issue.
after a long time
Yes, very busy working on a new job to pay the bills.
@@Joyplanes ok
Can you help me. beacause I didnt have enough money to make rc planes and rc stuff. can you help me?. I am from sri lanka. sri lankan people didnt do this hobby.
Have seen the same crash in other videos too. The designers should go back to the drawing board. Seeing the spec it is too heavy for it's size.
History of UAV would be nice.
A explanation video?
@@Joyplanes something like that.
A video about first RC aircraft Maybe.
Por esa pasta, me lo hago yo y aun me sobra....Tiene demasiada CA. en mi opinion. Saludos.
👌👌👍🌸
Yo so I read some comments and haven't seen anyone mention this yet. Why didn't you use the flaps? The flaps are what make the Bush plane what it is. They should have been down when you were taking off they create more lift and you will have a lower stall speed. Also you should not have been trying to taxi in that tall ass grass. You didn't even give this model a chance. That was definitely operator error.
It is because flaps are an add on, not a crutch, and the plane should fly perfect without them. The flap equipped planes I had (such as the excellent bush flyer Multiplex Fun Cub and a number of gliders) are harder to fly with flaps out, but they fly slower which is the point. From watching this and other videos the plane simply seems to fly really bad. This type of plane; high wing, semisymmetric profile, should be really easy, yo! :)
I think I know what's wrong. The tail is too short.
Not for beginners, and it needs lot's of improvements, and also good quality servos, motor, and ESC. Those recommended 3.7 g Servos, what a joke ! Also, the wings on mine are removable, the tailwheel is a separate assembly not just attached to the rudder.
The control horns, far too small and weak, I use bigger ones.
And all my electrics are nicely run thru black shrink tubing; I removed that silly tube which was inside the tail section messing up the whole looks.
Inside the "Cockpit" I'll add a floor and covers for the receiver, and only after first flights, an instrument panel, seats and a pilot.
Then, the motor will be mounted with proper pull downwards and to the right, and I'll check a few other videos about the correct C.G. before the maiden flight. I think, 4 c.m. as in the manual, is wrong and makes it tail heavy and uncontrollable leading to stall right after take-off.
As for the wing loading, I measured and calculated : each wing has 7.7 square decimeter, X 2 = 15.4, my plane weighs 670 g incl. a 3 s 1'300 mAh so I have 43.5g / square decimeter which is fairly low. (some of my planes have over 80) By the way when calculating wing loading, only measure the wings, NOT the part over the fuselage which provides no lift at all.
I spent many hours on it so I expect it to fly fairly nice.
Take-Off with half flaps of course and on a short cut grassy runway, in a few days. But only if everything is double-checked 100 % as usual.
Better to spend the nice electronics on a better airplane
So beautiful, so expensive and so flawed, a real shame.
As a rule of thumb don't buy kits with electronics included. They're basically useless.
change the engine thrust angles....
Did you mount motor a little to the right and a little down? Don't think so. Rookie mistake.
So your thrust angle was wrong which is why it banks to the left. Watch some videos on thrust angle before flying your next plane. It will save you money and frustration.
Gave you a thumbs up. Getting ready to order and was contemplating the included electronic kit, or just the air frame. Thank you for your review.
at :35, is THAT where a servo goes --- at the Tail.?!?!?!?? if so, WRONG !!!!!! the (MASS of the) piece of Large diameter tubing in the tail boom, NEEDS TO GO !!! googletranslate
Oye cuando vas a subir videos en tu otra cuenta
The plane looks great but it flies like ....
Some planes are not well constructed and life is to short to deal with these. It looks interesting but if it can’t fly good you better look elsewhere.
Looks like bad rudder
That is the problem of using materials of such poor quality and the lack of finish and more detail of it.
I’ve seen this plane being reviewed elsewhere and they had the same stalling problem it’s not a good flyer at all I wouldn’t recommend this plan at all there are far more stable better flying planes out there
Pretty much flys like all the cheap savage bobber kits I have seen, ...LIKE CRAP
too many strokes and wrong direction of strokes
Common problem or problems , under powered and out of balance wing structure. Poorly designed model equals poor preformance
Mine flew the same,over priced rubbish.
This plane does not fly right out of the box. Do not buy.
This aircraft is a bad buy has tending to turn left , don't buy
