Hi guys. Well, I'm taking the jump to upgrade to brushless and do the aileron and flap mods. I've been reading up a bunch on here and have come up with the following shopping list:
TR35-30C-1100 - TR 35-30C 1100kv Brushless Outrunner
HKz30A - HobbyKing 30A BlueSeries Brushless ESC
Z22003S20C - ZIPPY Flightmax 2200mAh 3S1P 20C (x2)
HXT900 - HXT900 9g / 1.6kg / .12sec Micro Servo (x6)
MA0950 - Master Airscrew propeller 9x5 $4.18 (x2)
TR-Wattmeter - Turnigy Watt Meter and power Analyzer
I already have a DX6i and a AR6110e receiver
A couple of questions. I see a lot of people using the Turnigy ESC but they were backorderd and the HobbyKing ESC looked good and had a 3a BEC with it. Also, it says is programmable from a controller, so I won't need a card; correct there?
Also, I got the AR6110e with the transmitter, is that receiver good enough for the SC?
Finally, I am planning to cover the airplane as well. I wanted to use Econokote like NeCubFlyer's videos, however I want to do an L-4 (military version) and of course Econokote doesn't have olive drab. Has anyone tried Ultracote? I see that the ParkLite is not recommended for foam but how about the standard?
Thanks so much for all of the help, can't wait to update my progress!

You can program them all from the controller, it's just a pain in the arse. The programming cards are pretty cheap from hobbyking, I think it's worth getting one just to save yourself the hassle. The motor you're getting is great, i have the same one in my cub. How are you mounting it? They sell great mounts for those motors on ebay, from customrcparts I think, but the mount costs as much as the motor. I covered my cub in profilm, which is apparently exactly the same as ultracoat (I think it's sold under different names in different countries). It worked great. Also, I have my doubts that that ESC can run 6 servos, and if it could, it would get really hot in the process. Better add one of these to your cart: www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=3735Also, regarding the servos, if you don't mind waiting for more to come in stock you should get these servos instead: www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=10344I'd pick the Corona brand over hextronik any day of the week. Oh, and final word of advice, the batteries you're getting are perfect, my favorites for the cub, but I'd get 3 if I were you, sometimes two batteries just isn't enough. |

Thanks for the tips. I think I'm going to get that mount. Looks pricey but probably worth the price. Yeah, Ultracote is the same as ProFilm, should do the job for me and give me the look I want. I'll also add that UBEC. Will any programmer card work for the ESC or are they brand specific?
Thanks for the help, I appreciate it!

Also, I got the AR6110e with the transmitter, is that receiver good enough for the SC? Yes that'll be fine unless you want to fly beyond your eyesight. |

That setup should be able to handle a larger prop, I suspect. I run a 3 bladed 9x5 on my 20A, PowerUp400 setup www.headsuprc.com/servlet/the-1548/GWS-9050x3-Standard-Rotation/DetailI would get a 3 bladed MAS 9x5 to go with the prop you are ordering. You could probably up the 2 bladed prop to a 10 inch, or get more pitch with a 9x6 or 9x7.5. The standard cub comes with a 9x6 prop. |

This is great guys, thanks so much. What do you recommend for a charger? Should I get a different ESC?

I was just looking at that ESC, and I don't think it is card programmable. I recon you should get a different one, if you have the spare cash. This one is a good pick: www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=2164 but they're hardly ever in stock. Otherwise get one of these, this is the one I got for my setup: cgi.ebay.com.au/New-Hobbywing-30A-BL-ESC-Trex-250-450-RC-Helicopter-/170501899761?pt=Radio_Control_Parts_Accessories&hash=item27b2b485f1 Both are practically identical, both programmable by the same card: www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=2169 If you want a fully-functional basic charger, you can't go past the turnigy accucel-6: www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=7028.jpg) They're in stock at the moment, so move quick. Otherwise you can search ebay for "b6 charger" and a whole bunch of them will come up, this is the one I got: cgi.ebay.com.au/Pol-max-B6-Balance-charger-battery-7-4-11-1-lipo-akku-/150519191922?pt=AU_Toys_Hobbies_Radio_Controlled_Vehicles&hash=item230ba49972 Whatever charger you get, you will also need a power adaptor for it (unless you want to power it from a car battery). You will not find a cheaper power adaptor than this one: cgi.ebay.com.au/AC-100W-Universal-Laptop-Notebook-Power-Adapter-Charger-/250499538029?pt=Laptop_Adapters_Chargers&hash=item3a52ef9c6d It's the same one I've got, and I can't fault it. Mine has been running for months without rest. If you're interested in being able to charge all your batteries at the same time, you should check out my thread on making a parallel charging array: supercubclub.proboards.com/index.cgi?action=gotopost&board=batt&thread=2542&post=17264Regarding your choice of prop, I can tell you that the Master Airscrew (MAS) 9x6 draws 18A, and the MAS 9x7 draws 20A. I'm currently flying with a MAS 9x5, but I haven't checked how much power it draws on my wattmeter yet. |

Would the power adapter that comes with the DX6i work for the charger?

Would the power adapter that comes with the DX6i work for the charger? No. You need minimum of 12-18v and at LEAST 5A, 6-7A are better. Download the instructions for stick programming an ESC. You'll buy the programming card. If you are going to put 6 servos in it, you NEED a UBEC or a higher end ESC with switchmode BEC of at least 3A. |

I see that the ParkLite is not recommended for foam but how about the standard? Thanks so much for all of the help, can't wait to update my progress! Hi Husker, The Turnigy motor is good and I have flown this one in my cub. But I would recommend something different. Heads Up RC also has a 35-30 1100kv and it has a current rating of 25 amps. The Turnigy from HK has a 15amp rating. This is a huge difference and what I like about the motors Jeff offers at HURC is he has done all the work for you. Follow this link: www.headsuprc.com/servlet/the-1427/3530-dsh-11-Outrunner-Brushless-Electric/DetailYou have the prop data and you already have an idea of what to expect with the different props. Depending on how you test and the battery you use you will get slightly different readings but I can tell you that they are almost right on the money. HURC 35-30c $23.95 HK 35-30c. $18.20 IMHO the extra 10amps is well worth it. Also, After you pay for shipping they end up being within pennies of each other. If you go with the HK motor you will have to prop your setup not to exceed the 15amps and you will be way under the thrust that you can get with the other motor propped for 22 or 23 amps. The HK ESC has a switch mode BEC. That's good. IMHO I use external BEC's because I like the idea of being able to control my plane in the event the ESC decides it time to go on vacation. Other that that, I have no experience with the HK ESC's. HURC does have the emax series and also the ez series. The Ez 30 amp ESC is $16.00 bucks. If you decide to go with an external BEC( I highly recommend that) then your looking at around $30.00 for both products. Choosing the ESC / BEC is the hardest and most critical decision on the plane. If you have the time to do some in depth research I'm confident that you may reconsider your choice and if your budget allows, change this part of your setup. The servos are good and I also have them in my Cub. They were out of stock for months and I ordered these for another build from HURC. www.headsuprc.com/servlet/the-1410/SERVO--dsh---9g/DetailThey are $4.95 and the ones from HK $2.69 This is the power analyzer I purchased: www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=10786It works great and I have no complaints. All in all I think your setup is ok except for the motor. Like I said above the Turnigy motor is fine but I like the higher amp rating of the 35-30 from HURC. Something else to consider is the flat rate shipping from HURC. If you buy that motor and say pay a few dollars extra for the servos, you can start your build in 4 days. For $2:00 flat rate you'll have your stuff in 4 days( sometimes in 3) for $5.00 flat rate you get it in 3 days( sometimes 2). Ifly |

The stock motor and prop on 3S is a 13A setup. You don't gain a whole lot with 15A.
A caution - the cheap servos (SG-90, HXT900, and WAY worse the Turnigy 9gm) have almost 2x the amp draw on the BEC. They are decent in terms of FUNCTION, and overall seem reliable but when you start throwing a bunch of them in a plane converted over to Spectrum you are asking for trouble without a UBEC. Can you say Brown Out?

Can you say Brown Out? I currently have 4 E-Flite S75's in mine. I need to replace one aileron servo due to a stripped gear (from landing in a rough field) and am probably adding flaps. So I will need to buy 2 total @ $12..95 each I was seriously considering buying 2 TP SG90's from HeadsUpRC for $4.95 each. If you highly recommend I stay with the E-Flite servos, I will. Or, at 5 servo's are you going to say UBEC for certain? |

Can't help a lot with what to buy, just know that some are higher draw than others. I use the HXT900 all the time. I just limit it to 3 or put in a UBEC.
There unfortunately isn't a lot of data on servo power requirements. There is a mess of opinions on servos but with the huge range of use patterns and actual knowledge it make it hard to sort out.
There is a fair bit of data on ESC requirements. Read them. Figure on most ESC the BEC is rated for 2S. At 3S their specs are even worse. The majority will recommend you go to a UBEC once you hit 4 servos or more.
Since you probably should put in a UBEC anyway then those could be used.
Hitec HS-55 is kind of the 'standard' for servos. There are lots of folks that absolutely swear by them. Some swear at them. The cost 3-5x more than the HXT900 and probably have weaker gears. They are more electrically efficient.
A few years back the HS-81MG was kind of THE standard for tough metal gear park fliers. In actuality they are a pretty lame servo with funky POTs.
I got some Bluebirds for use in a slope Weasel-$15. Stripped out the first crash. I have some HXT900 in another sloper that have taken dozens and dozens of crashes and many were way worse. Still on the same gears. Go figure. I thought I was stepping up. Found out I could get metal gears so ordered those. $25 later I ended up with 1 good servo as the other one turned out to not only be stripped but the motor was bad. But the folks in the Weasel thread (long and extensive) love them.
I do comb through the groups (pretty obvious, eh?) looking for info. I offer the following quotes I cut and saved as others opinion, not mine, since I have limited personal experience:
[I have more then 14 Eflite 75's, after 6 of them stripped; I have given the rest away. Bad slop was also an issue....
Just a word to the wise though, stay completely away from E-Flite S-75 and Spektrum S-75 servos! I have some Spektrum servos I haven't tried yet, but the E-flites are basically the same ones with a different label and the ones I have are terrible.
futaba s3110s are great, way quicker, smaller, and WAYYYY more torque than an HS-55.
Moved on to Futaba S3110s. Same price range, much more torque, a little faster and a little smaller than HS-55s and GWS Naros. Have yet to have a stripped gear problem or any problem with them. Great micro-servo at competitive prices... I love 'em! They were my micro-servo of choice until Futaba discontinued them this year. Now they sell the S3114 in its place. Same size, speed and torque, but good at 6v where the S3110 was only rated for 4.8v. They also dropped the price! My new servo of choice, but I've yet to (need to) buy any
The Futaba S3110 is faster than the HS-55 and has bit more torque; it's also a bit smaller. The only things I don't like about the S3110 are the short wires and its control horns are flimsy compared to the HS-55. Otherwise, the S3110 is a good servo from my experience.]
Seems a number of folks don't like those 75's much.
BTW, do not mix brands on ailerons, flaps, and other symmetrical type servos. You get poor results, sometimes bordering one the bizarre.

Hi Husker, The Turnigy motor is good and I have flown this one in my cub. But I would recommend something different. Heads Up RC also has a 35-30 1100kv and it has a current rating of 25 amps. The Turnigy from HK has a 15amp rating. I know it says those Turnigy motors are only rated to 15 amps, but that's wrong, like most of the data that Hobbyking has on their products. On drivecalc the limit for that motor is listed as 27 amps, and when I run mine at 20amps the motor doesn't even get warm. One of the reviews is from a guy that says "Used this to replace the expensive rimfire outrunner on my gp reactor. Works perfectly, not even getting hot (barely warm) on a 12x6E while pulling 30 amps." Motors only really loose efficiency when they're turning power into heat instead of thrust. If the motor isn't getting warm it's a good indication that you're still within the efficient power range. |
