SuperSkids put a lot of testing in their products.They will not sell anything that is junk.I have full confidence in their products.( I don't work for them.Just a happy customer)

Cool thanks for the feed back. I broke a rotor head last night and while fixing it I noticed that two of the links weren't sitting right. They were on a funny angel. After getting the new rotor head on and adjusted the links so they are now sitting straight up and down. I can't tell you what a difference this made to how she flies. Before it was harder than hell to controll and this is how it came from the factory. Now I'm lovin every minute of learing to fly my new heli. I posted an add to sell it but I think I'll be holding on to it a while longer. hahahaha

joeyhatch11 -> RE: Walkera #4 Fixed Pitch Helicopter Forum (8/18/2008 11:59:49 AM)
Does anyone know if they make a better rotor head and rotor head core for this heli? The rotor head core is what I break pretty often, I dont know how but I do. And the carbon fiber piece on the rotor head gets cracked to eaisly. What to do, what to do?

Hey all, just love this little bird. Just put together my second BL Belt Drive DF4 and I could not be happier flys almost by itself. Now I am going to sell my other DF4 its a Brushless setup also but no beltdrive tail setup just the motor also come with a DD tail setup many many ex. Tring to get picture to show . Some of the parts are new in packs. 2 different frames you can use, Superskids, Supersids tail boom everlasting,30amp ESC and more. So if you been thinking of going Brushless here your start. Heil is well tuned and flown only indoors. PM me if you want to no more.

Does anyone know where I can find a vendor with a supply of rotor heads? Every place I've checked is out of stock. The version I use looks like this: http://www.nitroplanes.com/hm-4-1-z-02.html Thanks, Marc

joeyhatch11 -> RE: Walkera #4 Fixed Pitch Helicopter Forum (8/21/2008 11:30:19 AM)
Will that rotor head work? What's with the long posts coming off it? Any benefits with this one over stock?

Fugitive_Bill -> RE: Walkera #4 Fixed Pitch Helicopter Forum (8/21/2008 4:53:02 PM)
Yeah, Whats the wierd posts on the head. No wonder you can't find any.

I'm not sure of the evolution of the part, but it's a rotor head and guide ring combined in one part. Maybe it is a newer (or older) version of the part than you have. I've always been able to get the part from many different vendors, but for some reason right now everyone is out of stock. Attached is photo of mine. Is there another part I can use instead? Marc

Thats the head for 4#1, I like this type over the others because they don't have the little balls that break off too easy....complete #4 head will fit as does HBFP (need to use HB servo ball links) but the ones Im using now are 4G1-B metal heads....don't make it any easier to fly but near bullet proof, balls don't break and bearings don't fly out. You will need everything from swash up but can use the same blades.

You will need everything from swash up but can use the same blades. I would like to do the metal upgrade. On "the other rc site", Brett at East Coast Hobbies showed the complete metal upgrade. He has it as a kit, but currently out of stock. In fact, every place I look shows out of stock on the metal parts too. I'm going to have to be extra careful as I only have one spare rotor head left in my parts bin. [:o] Marc

dodgemcopter -> RE: Walkera #4 Fixed Pitch Helicopter Forum (8/24/2008 9:20:37 AM)
Yeah thats where I got my last kit from, extremely helpful guy too. If your not fussed about gettin them shipped I can PM you two aussie supliers that show parts in stock but not in kits. As we had a break in our australian iceage today I got all my heli's and charged every lipo I had and went out into the carpark. The only missfortune I had was to see how high my HBFP could go, and beleive me the radio range is a lot shorter than you think.......went its own way, stayed airborne long enough for me to say "oh well", have a giggle and go for a walk in the general direction. It came down at great speed and hit a high volt overhead cable, blades and fly bar in a trillion bits all over the road and there lay the heli, batt hangin out and all. The 4G1 head.......not a scratch.....not a bend, do that with plastic[:D][:D] The only small issue I have had with them is the tiny screws that clamp the flybar, when you tighten them up and have a few tip overs the screws wear a groove in the carbon rod. Efter a while it won't grip the flybar, metal flybar next[;)][:D]

Well, I cracked open my piggy-bank and bought a Blade 400. I'm tracking it across the country from Florida to New Mexico. I'm actually surprised at how much my flight skills have improved in the last month. Hopefully I'll be able to continue learning with my new bird. I wonder if I'll miss that glitch that causes the tail to jerk 30 degrees uncommanded? Or if I'll need to apply the same amount of rudder to keep the yaw to a minimum when I apply full power? Or if I'll be able to surf the wind gusts with as much fun? I plan to keep the Walkera 4#1 around. I guess you never forget your first. [;)] Marc

It arrived Friday evening. I got my first flight in just before the sun went down. The weather was crummy most of the weekend here but today cleared up so I got about 10 battery packs of flying in. Yeah, I'm a bit obsessed. [;)] I'm just getting used to all the power. I've moved over to another forum that has a more active Blade 400 group. But I'm not getting rid of my 4#1. Marc

I had gone from my Falcon 40 to a Belt CP and wasn't overly thrilled with it (although it is cheap and I guess you get what you pay for). I quickly upgraded and built a 3DX 450SE with a Spektrum DX6i. I'm thrilled with it (much more stable and responsive than the Belt) and love the DX6i as well. Bill

Fugitive_Bill -> RE: Walkera #4 Fixed Pitch Helicopter Forum (9/2/2008 3:51:05 PM)
How the heck did you go flying just before sun down and get ten packs of flying in? I thought lipo's could be charged at 1C max. You got 5 to 10 packs? Where's the Blade 400 forum at? I can't find any real exciting ones. A friend of mine just got got a Blade400, Another friend and I are thinking about getting one However, as for helis the #4,#36(using dx6i),#22 and CX 2(using dx6i) are enough for now.

I got the Blade 400 Friday evening and flew one battery pack. Then, I flew 2 battery packs on Saturday. Sunday weather was crummy and I didn't fly at all. Then on Monday, I flew 10 packs. I have 2 battery packs. I fly one while the other is charging. That went on throughout the day. I'm just hovering in the front yard so I do chores around the house while waiting for batteries to charge. The forum I found with an active Blade 400 group is helifreak. Marc

quote: ORIGINAL: bitzernohelp before you sell it try the 3 cell lipo i put it in mine and it is the difference between night and day 1/4 throttle is more than enough to make this puppy hum. the additional weight did not bother it. Quick question: I thought that 11.1V would kill the stock 3-in-1 receiver? Thanks, HansV.

quote: ORIGINAL: HansV Quick question: I thought that 11.1V would kill the stock 3-in-1 receiver? Thanks, HansV. Naa. There's a low drop out voltage regulator inside which can handle up to 15V. The MOSFETS which drive the main and tail can handle much more. The only thing you may do is blow the main motor MOSFET if it hit something at full throttle and stall the motor. I would recommend a fuse mod on the main motor. p.s. Been using a 11.1V lipo on my heli for many months now. -Dave

Fugitive_Bill -> RE: Walkera #4 Fixed Pitch Helicopter Forum (9/6/2008 3:55:22 PM)
I blew my main motor MOSFET. I had a spare 4n1 laying around, so I put the crystals in that, but the original was on 36mhz and the back up is meant to take 35mhz xtals. (I know doing this a bad thing) It works fine (even as far as range goes), but I have trouble getting it arm. When it finally does I can't get get trim lower enough to completely shut the motor(s) off. I've look in both the tx & rx and there is not 'sub trims' or mini pots to lower the throttle end point. Any ideas? I was thinking of removing ESC board from the 35mhz reciever and putting it in the 36mhz reciever or removing the dead mosfet and putting one in from the good board, but MAN I don't think I can solder that small without creating bridges, though could be the only solution I have on hand at the moment. HANS, If your worried about 11.1V lipo you could also just use a $7 1000mha 7.4v 2S Lipo, that's still going to kick the stock NiMh battery's butt. But I'd just go 3S feel the RPM! You can all LOL now. NO I was NOT using the fuse mod!! B!

setforvb -> RE: Walkera #4 Fixed Pitch Helicopter Forum (9/7/2008 4:20:46 AM)
Anybody have problems with their tail motor not keeping a constant speed when throttling it up? If I hold the heli and pin the tail rotor full speed, it will hit top speed, then drop to a slower rpm then back up to full speed then back down, etc... likes it fluctuating. I just installed a new tail motor too. I'm still a total rookie, any ideas?

HansV -> RE: Walkera #4 Fixed Pitch Helicopter Forum (9/7/2008 7:19:25 AM)
Fugitive_Bill, billmay: Thanks for the tips regarding the 11.1V. I have a 1500mAh from another heli laying around somewhere. I am already flying with the 7.4v 1000mAh and get 13-15 minutes of hover. I havn't flown much with it since it had bad vibration out of the box and I am trying to order a newer rotorhead (yes, blades are balanced). I am interested in the higher voltage since it severely lacks power which have caused me a lot of problems. Does anyone have the same problem with lack of power or do I have a bad motor? I have the same problem with the stock NiMH and LiPO. setforvb: Usually if the tail flucturates the gyro gain is set too high or something is binding. Have you checked that the tail rotor/pin/gear are proper connected and that the gear can spin the tail motor fairly easy when you turn the tail rotor? Maybe the motor is too tight on the gear. It could also be a bad gyro in the receiver. Try to turn the heli around the yaw asis while holding it and see if the gyro works. Doesn't have to be at full throttle. /Hans.
