Walkera 38# CH46 RC Helicopter. Modifications and tips

[Yayakills]

Hey man cool video.

um incase you dont already know, that helicopter is actually an indoor helicopter.

double roaters on both ends (4 in total) means that its highly subject to be affected by wind.

check out the 9100 double horse helicopter, its a single roater(sp), outdoor helicopter.

[onavianva]

something similar happened to me where one of the screws holding the rotor came off while taking off. instead of ordering new parts online and waiting a week for them i went to home depot and bought a magnet (about 14 inches long) and swept my whole living room carpet and found it! 8)

[tommcg46]

Hi Mike,well i can hover and do some basic flying,had to replace some part's also i replaced the square rod's that hold the wheel's on with aluminum tubing,worked out nice.Hope your doing alright Mike and take care.Tom

[tommcg46]

Hi Mike,well i can hover nicely but trying to go forward is quite the challenge.I've done your mods but it still hard to go forward,the only thing i know right now is this heli does not like any wind whatsoever.I'll keep you updated Mike. Tom

[tommcg46]

I'm hovering Mike but i went through about a gazillion blades,BUT I'M HOVERING. Tom

[tommcg46]

Nice vid Mike,very helpful.I.m new to heli's and this is my first heli,great choice

[mikesndbs]

@tommcg46 Your first one! you are making a brave start, be sure to check out the other guide/tip videos for this heli on my channel I have updated a fair amount with significant changes! one being you only want one swash plate to move a lot not both.

Thanks for the comment, just go easy with the controls, there will be a tiny delay to the inputs you make and make sure there is no wind at all

[peterthegreen357]

Americans also call it "duck tape".

[surdez52]

i need to take the body off but there are two steel round pens below the rotors that go threw the body with rubber grumets. is there a way to pull the pens out so the body will come up and out

[mikesndbs]

Oh you mean pins, these are fiber and simply pull out of the body. Make sure not to crush them as I think you will find they are fiber.

You will see I replaced mine with tooth picks

[surdez52]

how do i get the body pens out to take off the body, with out hurting the body, i need to change the front landing skid

[mikesndbs]

Sorry I don't know what you mean?

[surdez52]

front wheel broke how can u replace it

[mikesndbs]

Leaver it out with a flat blade screw driver and when you get the new one, file its clip down a bit so its not such a tight fit.

[Pompiesdorp]

I have a chopper like this one. This thing has given me a headache since I bought it. Just hope that this video will help me get rid of all these problems. Would like to finely fly this chopper.

[mikesndbs]

Hi, do keep at it and see my updated video!

[victorianbulldog]

HI there I am very interested in buying one of these helis. I am in the uk. where can I buy one from and what should I expect to pay? kind regards.

[victorianbulldog]

Dont worry about answering my question now. I soughted it myself! after some exstensive searching to get it for the right price!! Ive also figured out the correct setting to make this helicopter fly correctly.

[selby1011]

received mine 2 days ago,nice kit and i gave it a good checking over.The grub screws on the main rotor shaft were loose just as you found so i checked put thread lock on all the main locking screws,i also found that it does tend to fly backwards,so i altered the the front push rods so there was more travell on the front head which cured the problem.

[RailMon]

A great looking model that can be persuaded to fly reasonably well. So continuing from my last suggestions, the blades are ridiculously week and break at the slightest touch. Fitting 'AIREY HARDEN' blades is a good option. These blades are far more flexible and minor damage can be repaired more readily with 'LOCTITE' super glue. They cost the same as the flimsy stock blades. Land at the first signs of a low battery because 2.4Ghz receivers 'brown out' (switch off) if the voltage drops to low.

[RailMon]

I agree with your mods and comments, well done. One or 2 more you might find usefull. The battery tray is extremely weak, as is most of this model. I reinforced the tray with very thin ally sheet, but I also moved the tray 20mm forward and fixed it from the underside rather than the top. This of coarse improved the C of G and forward flight. Bending the top blade holders up slightly reduces blade strikes and fitting a 200mm lightweight wood dowel cross the rear legs stops model faling -over.

[nicocrux]

hey I just tried to take off the flybar and the screw got stripped (or whatever the term is for when the screw head is torn up) This prevents me from taking off the body and making adjustments. Any tips?

[mikesndbs]

If the screw is stripped as you say I thin k you will need a new one sadly

[rolex0071]

excellent 5 star video - rolex

[Jummy134]

Nice video!!!Very helpful!I own one of those too...I wonder if you could send me a message explaining what can i do with the mix screw on the receiver.!!!I don't know what it does...and i can't setup either! Thank you !!!Bye :)

[RailMon]

Best advice is not to mess with the receiver settings unless you know what your doing. It is very unlikely to have any beneficial results, honest.

[matthewking1997]

the modifacations made a diference to mine cheers

[matthewking1997]

5 star brilliant

[rolex0071]

Excellent video and top tops 5 stars to you. I had a 38 but sold it on because it had no forward movment. I fly the esky big lama 500 but have now order the new yellow 400D walkera with its 495mm blades, 650mm boom and canopy, big battery 11.1 1500mhz, and tail motor that works. if its good i will sell my lama and move on to this.

[mikesndbs]

Thanks very much :-) I have since done an update video an the performance now is far better. Please check it out and see what you think?

Mike

[NightFlyyer]

Very nicely done. I will have to make those mods. I can relate to the outtakes. The slightest wind and/or no way to slide in grass or on rugs knocks them over easily. Thanks for this and 5 stars.

[mikesndbs]

Hey thanks! I don't know how you find the time to respond to comments but I am very pleased you did! your videos are great and you are one heck of a good pilot

[klutch3]

any luck painting the fuselage?? anyone?? my RC shop had it for 2 weeks with no luck.

[mikesndbs]

Painting! why not just buy another colour one?

[klutch3]

because none of them are even close to accurate to the platform. i flew these in the US Marine Corps and would like to have it pained in the flat gray scheme with original markings. thanks anyway.

[VetteWay2Fast]

Great informative Vid! Am looking into purchasing this Heli, so this info might come in handy. Thanks

[mikesndbs]

Most kind of you!

Test yours when you get it, maybe it won't need adjusting. Then maybe start with moving the fore and aft bell cranks initially to get more control if required.

[ChappersSP]

Just make sure the sevro adjustment is set to its full travel, this increases the amount of travel even further of the swashplate, no need to mess about moving links!

[mikesndbs]

Hi, OK everyone has their own way to do things.

I did not want to increase the 'extent' pot as this would give too much side to side and can cause horrible rocking. But whatever works I guess :-)

[erh7771]

How do you set the servo to full travel?

Thx

[mikesndbs]

You can do it by adjusting the pots, BUT they are very hard to get back to where you started! big servo movements can cause rocking flight. I personally say leave them as they are. You want gentle moves with this heli!

[VoxRail]

Great footage mate! 5*...Rich!

[vetterman008]

Why not make a weight adjustment to the front of the heli? Same result less work. :-)

[mikesndbs]

The only good way to do this is to move the battery holder forward a little.

Adding more weight just would not be the answer as this heli is rather heavy as it is!

But the point is also that the controls are very weak so need to be improved for better flying and giving you a chance to avoid crashes from slight wind etc.

[seth364]

Sorry no clue on what you meant by get on

[mikesndbs]

How you get on with your heli

[seth364]

Hey, loved the video and im halfway done with the entire process thanks and good luck.

[mikesndbs]

Oh good luck, maybe post a video of how you get on!

[RCSuperPowers]

Oh very good!

[mikesndbs]

Thanks Dave! liked your crash save motor mount one too
