Model Forum / Radio Controlled / Water Models / October 2008My turn
I was just reading on OSE about rx power and a lightbulb went off! I never gave it a thought but in my group of rc boats, if i use the servos for turning, the propulsion suffers. I use a 9 volt flat battery but of lately, i use 4 AA good batteries that i check for voltage each time out and get over 6 volts, which is good. Now i wonder if certain servos require more juice than others. I read on servo box, 4.8/6.0v which gives faster action at 6v but now i ? the propulsion letdown when i start turning the boat and use rx separate power supply. Oh yes, THANKS! have a good day!  SignatureDLM digital servos draw MUCH more amperage than standard analog servos. > I was just reading on OSE about rx power and a lightbulb went off!

Jim, thanks for the reply. I'm retiring from forums cause i get banned due to being real honest and do not give out bad info which others think is bad info and they complain i one thing leads to another and etc. I wish you luck! Thanks for having me. SignatureDLM yep, problem with the forums is everyone is an expert. Unfortunately, the one who speaks the loudest and gives the most advice is normally the most clueless of all. Those of us with real knowledge just remain silent so as not to be bashed. So many of the forums have turned into dumbies training idiots. > Jim, thanks for the reply.

Thanks for having me. True, to a point. As a "newbie", I've spent some time lurking. It doesn't take long to figure out who the knowledgeable people are. I hope you will shrug off the bashing and continue to share your experience. When you live in a small town, forums can be your only source of good information.

Thanks for having me. Ok, i talked to Andy Kunz of former builder and owner of Rc-hydros escs. Andy said that 9 volt batteries have a tendency to drop off fast in voltage which gives RXS ( receivers ) a headache. Andy has said 9 volts is not the way to go. Either 4 AA's or rx power pack of 6 volts. I checked around for the rx packs but their size were to big for my size boats. I saddle packed the 4 AA's with a Du-Pro switch which allowed me to place each 2 piece AA with ease. The already 5 cell packs give a 6 amp total as do 4 AA's at 1.5ams each. Food for thought; some RX's don't like 9 volts as do some servos. Now i find some analog servos turn easier than others and thats the ones i go for. Now i'm in the process of using micro Deans plugs for the rx wiring so i can unplug the 4 AA's and use in other boats. I already do this with rx and antenna and just use 1 rx and etc. Jim was right on digital servos plus the price tag. I use JR. equipment except i use Fub. 3003 servos which have never failed. Make sure antenna is at least 19" long. Hope this help explain my first posting . SignatureDLM DLM, a question about the RX power. Have you an opinion on using lipo power to keep the rx power up? I have heard/seen this done with apparently no problems however I did read something on RRR recently that suggested otherwise. I understand that most RX's aren't actually rated above 6V but will take the extra voltage. Off topic, I kind of know what you and Jim are talking about RE: knowitalls..... I hope I do not come across as one on this or any other forum that I look at/post in. Basically to me, it is the sharing of info that I know works and I will only share if I am 100% in what I am talking about. I definitely agree with the comment of the more posts, the less they know sort of thing, I reckon it is a post count comp in most cases to try to get a good rep on a particular forum. Sorry to see experienced people leave the cyber world. The way I got to where I am in my boating has been because of good experienced comments and learning the hard way. Signaturedeestingray Mr. Des!; your one of the best posters along with Paul of your country. I tried a No Step One yesterday on 4 AA's in saddle packs and ran perfect. I started with voltage of 6.07 and when done has 5.95 voltage on a Fub. 3001 servo. I used Deans micro plugs so i could take the 4 AA's out and leave the rest of the Du-pro switch in place. Now as far as lipo rx power, the size of the lipo rx power is to long at 1.44mm and 7.4 lipo is too much juice. Ok, when lipos are charged; the full charge will be close to 8.44 volts which is too much juice for the rx. I think the answer is to have the correct height of antenna which the manufacturer recommends. This way, saves on the batteries and that part of the system. Hump pack packs to me would be top heavy. Now alot depends on location for rx power too. The best antennas were piano wire and silver solder with 16 guage wire soldered to piano wire and used spade clips. I used shrink for tip of piano wire so no eyes got poked out. I just covered the wire with 1/8" plastic tube. Have a good day. Reason i posted was , your one person who deserves an answer and your honest on your answers. Take care. SignatureDLM I switched over to running 7.4 volt Lipo RX packs about two Months ago on all my boats. I run a regulator between the pack and the RX so it is only fed 6volts. So far it has been working great. SignatureJohn Thanks for those insightful answers. I am on a fence at the moment on what to run. As some of you might be aware, I stay away from the internal combustion type boats for a world of electricity and have tried both ways of powering up. My biggest problem was on the receiver connection to the battery, for some reason, I could never keep a reliable connection and often had stoppages in the middle of the lake. So stopping short of soldering a wire and connector on the receiver I gave up and went to a BEC and love it but now I have the issue of less ballast and brushless power seems to warrant extra weight to keep the boat on the water.......one of those push pull things I guess... Off topic again, DLM thanks for those kind words. I wasn't fishing at all and am a bit humbled that somebody takes the time to read what I have written and agree with it. The hobby can greatly benefit from good clean opinions and I also believe, good clean debates. It is a shame to see experience walk out the door anywhere you are. Signaturedeestingray First, a regulator for the lipo is perfect answer for voltage, THANKS!--------Mr. DES; i use a balloon which cover the rx and keeps connections in place. I got in the habit of checking for fraid wires and like to give a little tug just to make sure. I still like the 9 volt battery and weighs less than 4 AA's and will check today on a regulator. I have used the same rx for over ten years, i just give it a shot of Corrosion-X and a shot with hair dryer and away i go. I went out again yesterday and the 4 AA's did there job. They dropped from 5.95 to 5.82 volts, so i can't complain. People, have a good weekend and thanks for the regulator tip!----- Put 1 or 2 AA's in boat with velcro and place where needed. You can always remove them. SignatureDLM Jim" <jim@slaughter.org> wrote in message news:%snGk.1002$yI6.952@nwrddc01.gnilink.net... > yep, problem with the forums is everyone is an expert.

Good - bye! Take my name off your membership. SignatureDLM > I got a notice, i'm being censored on my postings. Good - bye! Take my > name off your membership. f.ck the forum and its censors and use the newsgroup as it is intended to be used, on a Usenet news server. SignatureBlack Dragon A bureaucracy is like a septic tank -- all the really big sh.ts float to the top. What the same hill are you talking about? I posted a message and nothing was wrong in my message at all and i got censored. What are you talking about as it was intended to be used. News, i wasn't even using the news, i was posting. Yes, i'm mad and i did nothing what so ever. I have a reason and i would like an answer and a apology from this site. When i found out i got censored, i deleted my postings, that's what a normal person does when they just got dumped on! SignatureDLM There are list of a few words that spammers use frequently to post spam on this forum that are automaticlly censored. This is done automaticlly by the forum software, it's nothing personal. So if you have a word that has been censored, which will show as ***** then perhaps chose another word. There is also another measure that detects another list of words that the spammers use. If a post has those words then the whole post is put into the moderation queue. Again, this is done automaticlly and is nothing personal. If the post is not spam, then the moderators will approve it and it will appear (as I have done with your post). These measures have been put in place to keep the posts in this forum about model boats and free of spam posts. Sometimes genuine posts get caught in the filters, but that is better than letting any of the spam through. To give you an indication, there are currently more spam threads that have been moved to a hidden area than there are real posts in the General forum. SignatureJohn I typed a message that kneedeep has an opinion like everyone else and is entitled to say so. Now when i got done talking about boating,; a message said i was censored and my posting must be approved. I never been sensored on this site and i could find a reason to get censored now. There was nothing derogatory in what i typed. Water over the dam now and damage has been done. Good-bye and good luck! Remove DLM from membership, thank you, no replies.--- I'm not thinskinned but a few have to ruin things for other people. SignatureDLM Sigh... I guess you didn't even read my post explaining how it works? Anyway, best of luck DLM, you are welcome back should you choose to visit us again. SignatureJohn Yes, i read your post , but i'm no guru on the computer and i look at it from a laymans view and common sense view. Now all that spammer stuff is ROTTEN and spoil it for the rest of us rc boaters. That doesn't help the new people interested in boats. I just about eat and sleep rc boats now that the economic picture is not great. Now the rc boaters ( electric ) are a super small % and bother noone and each enjoy helping others. When i started, there were no sites to go to and didn't know little unless you bought plans. You replied on Jerry Dunlap,Jay Turner in RCBM Magazine for help in the middle 90's. You people will do fine without me and what has happened will help others to understand. Take care downunder, ok! SignatureDLM > What the same hill are you talking about? I posted a message and nothing > was wrong in my message at all and i got censored. What are you talking [quoted text clipped - 3 lines] > When i found out i got censored, i deleted my postings, that's what a > normal person does when they just got dumped on! "This is not a list. This is not a board. This is not some web page forum with rules and moderators. This is USENET. The wild west of online communication. Where trolls and flames roam rampant. Where you keep your asbestos underpants handy if you lack wit (or have an ego that greatly exceeds your actual abilities). If you don't like it, feel free to run back to the comfortable safety of moderated web forums and mailing lists where everyone lives in enforced peace and harmony in the land of Nod." -Cichlidiot There are many way to read this NEWSGROUP, the web forum your reading it from now being the worst of them. This isn't a whole lot better from the user interface perspective but it will assure you will not ever get censored. It's Google Groups interface to rec.models.rc.water on Usenet: http://groups.google.com/group/rec.models.rc.water/topics See also: http://groups.google.com/groups/dir?q=rec.models.rc If you like what you see and would like a much better way to access USENET, please feel free to ask how. SignatureBlack Dragon Once upon a girl there was a time... You really get a kick out of what you type. Question, why bother this site as it doesn't mean a hill of beans to you and to others it means some kind of support in boating. Speaking of asbestos underwear, i think yours must be real tight . You like to irrate to see what kind of answers you'll get which means your not much of a person. Now a REAL man not a spammer would present themselves in a manner like you have presented yourself. Take a hike. Why don't you take your turn in Iraq! I'm laughing at you and you made my day and i can chuckle the rest of the day now. Have a good day! Take 2 aspirin and call me in the morning.
