You found the Turnigy to be crap compared to the Hextronic? I thought it would probably be Hobbywing but don't know that. What was the problem? |

@john66, good one!!! How about we try hanging that off of a "Dillzio Motor Mount" ;D Hey Dill, I'm really starting to like the way that sounds!!! ;D This is the SBEC that I ordered from HK. www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=10313I hope I did not order something wrong? It seemed like a good buy and is a switching BEC. The amperage rating seemed to be good even if you take 20% off for overrating. 21 grams is on the high end of what I was looking for but I think it will be ok. I also placed another order from HobbyPartz.com Quantity Item 1 Alpha 480 (910kv) Brushless Motor www.hobbypartz.com/75m20-optima480-3010-910kv.html1 30A Electronic Brushless ESC Speed Controller [Volcano Series] www.hobbypartz.com/30a-electronic-brushless-esc-speed-controller--volcano-series-.html1 UBEC-5A-HV (High Voltage Ultimate BEC) www.hobbypartz.com/ubhvoulbe.htmlI think I have ordered enough equipment for a few different projects. :-) ginginho, I did order the "Dillzio Mount" off of eBay. Hey Dill, how do you like that? "Dillzio Mount", nice ring to it. :-) I just ordered the stick mount because it was cheap and I would like to see one up close. I will also take your advice and order some of the GWS props. I figure now that I have spent a little over $150.00 on 3 Brushless Motors 2 BEC's 1 ESC 1 Custom motor mount 1 Stick mount 1 Wattmeter A bunch of props and some small parts I'll be just about ready to start doing some testing and see how this all works together. I figure about 3 weeks to get all the parts and another couple of weeks of bench tests. Does anyone see any problem with anything that I have purchased so far? Anything that you would say "don't hook that up together"? Ok, I know that someone will comment about all the stuff I bought and ask why. My 10 year old is flying the HobbyZone Champ, secure.hobbyzone.com/HBZ4900.html and should be ready for the upgrade to my cub by the end of the summer. That gives me the excuse to buy another cub and do all the mods with a little experience on my side. Can anyone recommend a cheap brushed ESC that is available somewhere in the US to use with my stock setup while I'm waiting the next few weeks for my parts to arrive? I would really like to install my new AR6110e receiver and try out my flaps. I have not been able to find something in stock. |

The trouble with brushed ESC is none (I know of) have a BEC capable of handling 6 servos. Most can't handle 4 servos on 3S. You'll need a UBEC for that too. Here's one of your larger selections: www.bphobbies.com/view.asp?id=V573706Pay attention to the specs, especially the LVC and BEC. Most have a lousy LVC and low end BEC hinting strongly at their NiXX background. |

Dillzio, Hey, I will take you up on that offer for a pint. :-) is it true that you drink your beer warm down under? No, that absolutely is not true! That's the poms that drink 'warm' beer, but that's only because it's generally so cold over there anyway that they a) don't really need to refrigerate it and b) people don't really like drinking cold beer when it's cold outside anyway Catching up for a pint would be great though! DillzioDid you say you have added weight to your cowl in order to balance your Cub? I think if I'm reading the thread correctly that Ginginho is concerned that the 35-30C or the 35-36C will make the Cub to nose heavy. What a re your thoughts on this? Yes, I have to add about an ounce to my cowl for it to balance right, but I have a few overlapping pieces of profilm on the back of my fuselage as reinforcement that throws the weight off a bit. There's every likelihood that without that extra weight on the back of the plane, it would balance out OK. You found the Turnigy to be crap compared to the Hextronic? I thought it would probably be Hobbywing but don't know that. What was the problem? well, this is the review I wrote for it on hobbyking: "I'm not too impressed at all with this item and particularly, the blatantly false advertising HobbyKing are using on it. "an advanced switching DC-DC regulator which will supply a constant 5A" PIGS ARSE! I just hooked mine up to a light bulb that was running at 2.6 amps, and the voltage dropped down do 4.2 volts. Tried it with the BEC set to 6v and the voltage dropped to 3.4 volts! Good for 2 amps constant 3 amps max ONLY" All the reviews for the hextronic one are pretty good. @ifly: Yes, I do like the term "dillzio mount", I feel very special indeed :o) I just wish I remember if I heard about it from someone on the forum here, because if I did, I'm unduly steeling their thunder. If you want to quote other people's text, just push the 'quote' button in the box their text appears in. |

I'm pretty sure that mount had been highlighted on here well before you joined, therefore you are indeed a thunder stealer (which fits within the description you being the offspring of the list of criminal types John66 outlined!) ;D |

LMAO, touche! I'm pretty sure that mount had been highlighted on here well before you joined, therefore you are indeed a thunder stealer (which fits within the description you being the offspring of the list of criminal types John66 outlined!) ;D Hey, I only recommended the mount to people cos I thought it was good, I never claimed it was my own discovery, and I certainly never dubbed it 'the dillzio mount'. I'm quite happy for people to call it that if they want though  At least I still have the claim to fame of 'the blingiest cub on the forum' ;D Oh, and just to set the record straight, I live in Adelaide, which was settled by aristocrats, not convicts  |

Mine has a street lamp pole shaped dent on the leading edge of the left wing. I wish I had video of the flat spin that occurred when it hit. It was spinning at about 200 rpm and looked like it auto-rotated 15 feet to the ground. Only damage, other than the wing was a bent landing gear and the obligatory cracked cowl. |

@ Dillzio, John66 & Ginginho I never thought a thread could cause me to have tears running down my face  . I cant stop laughing!!!! ;D You guys are the best. A little comment about warm beer may start "World War 3". Testing: Thanks Dill, It seems to have worked! When I pressed the "Quote" it opened the message box and inserted the complete text. I could not find an easy way to just select a small portion. I had to delete the stuff I did not want and put the "quote" sign in front. Am I missing a shortcut? @ Flydiver, Thanks for the link, I will take a closer look tonight. One of our engineers has confirmed what I said about "Water Break-In". He can not see any benefit other that seating the brushes to the comm surface better. He questions the procedure because the term "break in" would mean doing this on a new motor. A new motor should have seated brushes from the factory. He questions the quality of a motor if such a procedure is needed. Of course he wanted me to add that we work on Elevator Motors and Generators!!! It would be very difficult to submerge a 3 Ton Otis 77 Gearless Hoist Motor in water, apply 260 Volts and run it: We simply seat our brushes using sandpaper. I am very interested in this and I think after all my mods are done I will experiment with one of the 2 Stock SC motors I have. Last night I found an online Hobby Shop I thought was very interesting. Take a look www.headsuprc.comThe web site is very simple and easy to use (one of the best I have found) and the information I found was fantastic (for my limited knowledge). I thought it was very interesting that when you click on any given motor (lets say the 35-30) it gives you all kinds of information and test data like thrust and Amps with different props ect. Under "Categories" INFORMATION PAGES, The explanations were very clear and easy to understand. I realize that you have an in depth knowledge of electric RC and this may be very basic stuff for you but for me it was like someone turned a light bulb on in a dark room. With the prop, thrust, and amp data I am sure that I will have variations because of battery packs and the motor manufactures as well as other factors. I compared the 35-30 and the 35-36 motor to the Turnigy and they were almost a match. It would be interesting to know who makes those motors. I ordered some props from them and already got an e-mail that they were shipped today. Prices also seem to be ok. Thanks for all the help: |

I forgot to add that they have flat rate $5.00 dollar shipping from Florida. Almost seems to good to be true  As a test I added over 100 dollars of motors,Esc's and all kind of stuff to the cart to see if the shipping stayed the same and YES!!! Still $5 flat rate. I hope I get the props ;D |

Jeff at HeadsUpRC is a great guy. Your reaction to his information on motors was the same as mine at that stage. His support is in a class by itself. His shipping charges are really nice. I wouldn't be terribly surprised if some of the HURC and Turnigy motors both came from here: sxicl3082.en.china.cn/I'm pretty sure some of Jeff's do, and mostly Turnigy doesn't make anything, it's just re-brands. Breaking in a $10 motor at the factory! HOOT! Quality assurance in China! double HOOT! Yes, you do a water break-in to seat the brushes. On something like the Cub motor it may be of little use. I read one thread where the author tried it on a 400 and compared it to one that got no break-in. No difference in performance. No long term study was done for reliability, difficult to do in RC as many (most?) motors meet their demise by catastrophe long before wearing out. On some of the higher performance brushed motors of not long ago it was a common practice. They did use softer brushes (replaceable) and those were not pre-shaped. You hardly ever see that stuff anymore. I have one in a 20 year old glider. It's a monster and cant' hold a candle to an outrunner 1/3 it's size. |

Glad to know you've heard of them and know someone down there. After I placed my order last night I shot off an e-mail to HURC letting them know I thought there site was fantastic. I wish all the sites would list props the way they do.( so easy ) Remember my question the other day about an explanation that could be understood by a 10 year old? This should be mandatory reading for anyone looking to upgrade to brushless or better yet for anyone new to ERC. www.headsuprc.com/servlet/the-template/faqindex/PageA 35-30C motor from HURC with Priority shipping $ 28.95 from HK $ 23.51 A 35-36C motor from HURC with priority Shipping $ 28.95 from HK $ 31.50 I'm kicking my self in the A....  Now I have to wait another 2 to 3 weeks to get my stuff from HK and I could have had it in 3 or 4 days for almost the exact same price!!!! You know the old saying "shoulda,coulda,woulda" ;D |

At least I still have the claim to fame of 'the blingiest gimpiest cub on the forum' ;D Corrected. ;D way to go Captain Killjoy, you've once again brought me back down to ground level from a state of optimism. Anyway, at least I didn't stuff up my cub due to something as stupid as reversing the eleva... or wait, nevermind.  Regarding the water-break in, I've tried it before and I thought it worked great: supercubclub.proboards.com/index.cgi?action=display&board=ts&thread=993&page=2#18542I think the best thing about it is all of the $hit that it cleans out of the motor - once you try it for yourself you'll see what I mean. The other good thing is that it allows you to break in the commutators without them arcing and burning up the brushes. |

Yeah Fly is correct, all those motors are made at the same factory, known as XYH amoungst other re-brand names. There is another factory for cheapo brushless which are known as Suppo, again in China somewhere.
