This morning was perfectly calm so I took the 4#3B outside for a couple flights. Lots of fun! More room means more speed.

But I've got to watch the distance I let it get away from me. It doesn't take long for the little heli to become a dot and loose orientation.

AtomicFlyer, nice flying! It sounds like your stove is a heli magnet lol.. A small trick that I learned very fast is to immediately remove the throttle before impact. This will save your blades and other parts. Going fast is a lot more fun than hovering around and it looks like you have plenty of space to do that.

I noticed that your gyro makes the same fun as mine when going left. I havn't really figured out a solution for that but it makes CCW turns look less smooth than CW.

I don't have this mod as it's purpose is to reduce the responsiveness of the heli by adding weights to the flybar. I guess your question is where to place these weights. The rule is the further out they are the slower the heli will react so you can experiment to find the right set-up for you. Make sure that they are place at the same distance from the center to avoid vibrations and bad flight charateristics.

Hello fellow 4#3B fans!

I've been lurking hear about a month since I got my heli, and I'm a very happy boy, uh man. A bunch of firemen at my station purchased these beauties to fly during down time. I probably fly the most because I have an empty garage at home as well to mess around in. I have no prior helicopter experience, and the first couple days were challenging to say the least. But after a solid month I've got my tail in/out/sides down pat, and can square and circle CW. Need to start practicing CCW! The 4G3 looks so tempting, but I think I need to master my basics first. What should I start practicing on the 4#3B? Was thinking figure 8s then maybe attempting that move where you side fly in a circle with the nose/tail in? Is that about the pinnacle of 4 channel flight, or is there more? I try to get to 3-6 flights in a day. My wife doesn't seem too thrilled.

WowHobbies Main Brushless Upgrade

HansV, this is for you, since I noticed you asked about it a few days ago

First of all, to be honest, it's a challenging upgrade, but through trial and error, I think I can shave an hour or two off your upgrade time if you have any questions. The only parts you need are the Fegaio 12x22, screws, the steve channel conveter, the ebay esc, and a wow rudder blade.(it's larger than the stock) Do not waste your money on the extended boom or the pinions. The pinions don't fit properly and slide off the shaft. Use your original pinions. You'll need to drill out the center to make it fit on the fegaio. I used a micro phillips and slowly carved through. It doesn't have to be perfect, the gears allow for a little play and offcenteredness. Also don't order the extended boom, it's way to long for the tail wires anyway, and the wow rudder blade gives really good tail authority. Unfortunately, Wow won't refund on mods, even though it's their fault. However, I'm still buying from them because the prices are good, and this guy has a good turnaround time. Also seems to be one of the only all in one shops for the brushless mod.

So any way, the frame needs slight scraping to allow the motor to fit. Nothing major. The soldering is probably the hardest part, but Wow has a diagram that's pretty self explanatory. The canopy is a little crowded now, but I managed to squeeze everything in. Also put a switch to separately power up the ESC. This allows you to program it with your Walkera 2.4 transmitter. I only changed the throttle curve and range of the throttle to allow the throttle stick to remain in the center when hovering instead of the upper half. I'll try to put some pics up later.

CONS:
Challenging yet rewarding install
NO refund for unneeded items from wow
No torque on really low end.(only consequence being that I can't flip my 4#3B upright anymore when it's lying on it's side)
May need to buy 2 ESCs as my buddy did. (again, no Wow refund)
Tight Canopy
Battery pack needs to sit back further a bit now
Pricey, around $60-$70 shipped

PROS:
LONG MOTOR LIFE!!!
Runs slightly cooler
Perhaps slightly longer run time
Brushless is cool

Don't think I'll attempt the iffy brushless tail conversion for awhile, although Wow did just get a high speed Steve converter. No useful diagrams up yet on the sight though. Well, that's about it, any questions? he he

Anyone know who sells the cool kickstand in this video? The little stock one is one of my main gripes with the 4#3B. Also that metal piece on the rotor head looks like it would prevent that small linkage to the flybar from always popping off.

Hey Kronium. Thanks for the advice on the brushless. I think that I will give it a try since I just blew another motor. Does it mean that you don't have to solder on circuit board?

If you are done doing circles the next challanging thing is doing them backwards. That is pretty hard. Doing nose-in circles is pretty easy and looks awsome. Love that one. If you do them really fast it looks like a nose-in funnel with the tail high and the nose really low. Havn't comleted the tail-in yet, but is still practicing. Really funny

Flying with the tail first is the hardest thing I can think of in the living room. I guess if you go outside it could do a loop, roll and stall turn. The only problem is that you need space and hight and it is a very small heli so it is easy to loose orientation.

Regarding the link, I am not sure I want to go with this upgrade. The heli is all over the place or maybe it is just a really new pilot. I don't really have issues with the linkage since they usually only pop off after a crash and you just pop them back on when you get the heli (unless you use your creative method lol).

/Hans.

HansV, the conversion needs needs three solder points on the led side of the receiver board. Two opposite the red/black power leads, and one on a chip that outputs the throttle signal. The original Main motor plug on the receiver is actually unused. If you can consistently solder tail motor wires, I think this is doable. Tinning you soldering tip as well as both solder points will really help.

Thanks for the backward tip. That totally eluded me for some reason! Hopefully I can get the tornado down first, then I'll try everything backwards. Happy flying!

Yeah, my gyro causes st.st.st.stutter going CCW. Not sure why.

Sometimes I can pull off nice CCW coordinated circles. But the CW circles always look better!

AtomicFlyer, is there an actual gyro in the receiver board?

So curious, how many flights can you guys get out of a tail boom? I found a guy from ebay that sells aluminum booms. He cutom cuts to your spec. I found that they last much longer than the carbon booms. They are kinda pliable, but you just bend them right back into shape after a crash. I probably average one boom change for every tail motor change. 75 flights maybe?

I believe the disks go between the sides of the blade and the blade holder. You screw through the disk. I've found that the MIA upgrades are unnecessary. I didn't see much difference when flying. The frame upgrade looks promising, but I hate the fact that you have to glue it all together.

Glad to see that I am not the only one that has that experience.

Kronium, yes there is a tail gyro in the receiver board. I actually holds the tail quite nice but can not be adjusted.

I only broke one after a very hard tail landing. It fractured but I pushed it in and kept flying and is a long, long time ago. Actually I havn't really broken anything lately except for a bend rotor head due to a hard wind gust outside. Blew it sideways into a brick wall pretty hard. Stole another one from my spare heli, but now I am pretty much grounded due to no more main motors. Parts will arrive monday next week so it is going to be a long weekend.

HansV, must be nice having heli experience! I've gone through about 5 booms already. he he. At least the purchasing of parts is slowly diminishing with consistent stick time.

btw, did you decide to go through with the brushless upgrade?

Anybody have a servo that twitches? You know like how you pull down the right stick and release it and the servo twitches then stops? My Aileron servo does this with no input. I'm thinking it must be the receiver because it's supplying some kind of power during the twitching. Or could it be a bad servo. Doesn't really affect flight, as when you give it aileron input, the twitching stops. Thanks!

Hi Kronium, I usually crash to the side and not on the tail, so that probably explains why I dont use a lot of tail booms. Main reason for crashes are usually that I try or practice something new and when I feel that I am about to loose it I throttle completely down immediately. That is usually the best idea when inside flying over a hard wood floor. Outside I will give full throttle and try to gain hight. I don't really have hughe talent for flying but stick time is the key. Also I found that when I am calm and not aggressive it is easier and will hover on a spot and fly where I want it with almost no stick input. Aggressve is a lot of fun and it really goes fast but it usually ends up sideways on the floor

I used an hour or two last night reading about the upgrade. Did you also install brushless for the tail motor? I will order one or two sets this weekend. Did you convert to the 4#3 main gear and which size main motor gear do you use?

/Hans.

It is the servo. It happens after a bad crash and the servo will kind of jitter until you move the stick or apply a little force on the servo arm. Unfortuantely that is one of the more expensive parts, but you can fly around with it until you get a replacement. I saw that a lot of the 4#3 but have actually never experienced it on the 4#3B since it uses slightly bigger servos. Had one that got completely stocked and another one that suddently got stocked during flight. The latter one caused a lot of fun. It is really hard to land it without being able to use the aleron.

Hans, re-read my first post about the conversion if you can. Don't get the pinions on Wow, they don't fit. If you cut them and make them fit, they will spin down off the end after a few seconds. I may try to glue it on and see. For now, just drill or carve out the stock motor pinion. It doesn't have to be pretty. Didn't do the tail. Right now it seems that you need two cell batteries that cost more. The have a new converter/esc in one on Wows site called the flea. Not sure if it will work with one cell batteries. I'll let you know when I get more info and they post a diagram on how to convert. It's pretty tight with main, I don't know where I'd fit everything with the tail as well. I'll head that way in a month or so, maybe with a MIA frame. I keep you posted

As for the servo, I managed to rebalance the helicopter. It seems that if it's trimmed a little out of that twitching range, it's fine. weird. But I'll expect it's ultimate demise soon. Do you really think it's the servo? I'll probably order just in case. are the pair of servos interchangable? either aileron or elevator? Thanks

servos are interchangeable. maybe there's a bad wire connection or some kind of electronic interference? wiggle the servo wire carefully and see for yourself.
