Dat is erg handig, bedankt Ron

Thanks Tim, my charger plugs into the balance battery plug only.  If I keep both batteries connected will it pull too much of a load for the small balance wires and plugs? I have charged the batteries several times now and didnt notice anything getting hot.

Thanks guy's.  Simon you were right. I did mean that I was charging the 'batteries' not the individual cells. Sorry - I did say I was new to this !   I have read Tim's link and he seems to encourage charging the batteries whilst still connected together ?  As long as its safe and doesnt effect the life of the batteries I would prefer to keep them linked together.   Regarding charge rates, I assumed that the slower the charge the better it would be for the battery?  It seems I'll have to do some more reading on this subject.   Thanks again both of you.  

I'm relatively new to electric flight so please bear with me.   I run two packs of 25C 2100 3S1P in parallel (this provides perfect balance without having to add extra weight).  I charge the packs with a Prolux Lipo balanced charger. I keep them connected in parallel when I charge the cells and up until now I charge each pack separately, however after charging just one pack and checking the other, I noticed that the ‘uncharged’ cell had achieved 80% charge rate. By charging the ‘uncharged’ pack the charge rate finished both packs went up to 95%.  What’s going on? Should I disconnect the packs before charging?  If it makes a difference I’m charging the cells at 500mA.   Thanks in advance,   Tony  

I'd love one. Me please !!!

Me Please......

Yes please.

Me Sir.  I want one !

Yes please, I'd much appreciate a new project. Thanks

Please, please, please.

Guy's, the talk of 'Clamp on's' and 'Speedo's' has left me blushing.   I think for the moment I'll just try and get the thing (aircraft, Eric) into the air and down again without bending anything. FYI. I've mastered a Harrier on my RealFlight flight sim, shame because I don't think my Seagull Innovator will perform such a maneuver ! Thanks both of you. 

Yeh, thats just my holiday home, wait till you see my Somerset mansion ! (In my dreams) Timbo, how can I measure the current draw?  I suspect I need to spend some more cash on another bit of kit?  At my level (LOW), would it be worth the investment ? Thanks again

Eric I heaved it out the window and look where it got me. http://uk.youtube.com/watch?v=tgWIdpegfuc Thanks agian eveyone.

Thanks Timbo and Andy, looks like I'll have to dust off my old soldering iron.  Andy the link demonstrated the point.  Thanks Thanks to everyone's help, I now know what I need to do to get my trainer running correctly and safely. I've spent hours on the flight sim, seems like all that's left is to do is to find someone to help me get the thing into the air. Thanks again everyone, very much appreciated.

Timbo, you really are a wealth of knowledge, I dont suppose you want to built the next one for me do you ? I have a lot to learn but I'm a big techie and like things complicated.  initially I thought 'lecky' flight was as simple as stuffing some old batteries into a cheap plane then off you go.  How wrong I was! My next question might sound completly stupid but how do I know that the batteries are about to give out mid flight? I'm using 2100mAh 25C 3S1P Lipo's (two of them strapped together now) with a GWS3020/8T motor with a  APC C-2 prop (279 x 140) and a JP E-Pro 30A ESC Thanks again.

Thanks David and Timbo, Any advice about what electrical connectors to use to connect the Lipo up to the ESC and the ESC to the motor.  I’m currently using normal ‘household’ block connectors but I can’t help but feel there’s a much better alternative that I’ll need to install before its maiden flight? Timbo (after spending a lot of time reading different threads on this forum it seems you are the 'electrical guru' ),  on the back of the ESC there is a metal block that I assuse to be a heat sink ?  How important is it that this heat sink (assuming it is) is ventilated?  I've used it as a nice solid surface to apply some double sided velcro to hold the ESC to the airframe.  Also, you say chage in Parallel, how do you mean ?  I last built a plane from scratch at the age of 12.  Its funny but in all that time I didnt notice that my fingers must have got much fatter!  Its taken me ages to install the radio gear and dress all the wires so they are all nice and neat.  Can you give me any advise on this subject? Perhaps I'd best take that one up with someone medical. Thanks again

Thanks for your quick reply. Burning the midnight oil? I’ve just sent off my subscription to Join the Weston Model Flying Club (Weston Super Mare).  I’ve spoken to a few people there and they seem like a great bunch who are keen to give me some much needed help). As an extension to my original question, what sort of connectors do people use to connect the Lipo up to the ESC and the ESC to the motor.  I’m currently using normal ‘household’ block connectors but I can’t help but feel there’s a much better alternative that I’ll need to install before its maiden flight? (Note to the moderator; should I have started this thread in the ‘Electric section’ ?)Thanks again David.

Hi Guys.  I’ve just finished putting together my first aircraft.  I’ve been into RC cars for a while and it seemed like a natural progression.  I have started with a Seagull Innovator EP.  I am up and running but she seems to want a lot of additional weight up front to balance the centre of gravity.  In fact the weight required is the same as the 3S Lipo battery that I’m using.  Therefore could I install two batteries in parallel with one another?  If I have to put weight in the nose best it be useful weight ? Whilst writing, I’m using a Futaba 2.4Ghz 6EX and using this excellent forum I’ve read that I’ll need to reverse the throttle channel (CH3) but it also needs for the rudder (CH4)and steerable front wheel to be reversed.  Is this normal or have I done something wrong ? Any help you can give would be much appreciated.Thanks

I'm new to all of this so I'd love to give it a go.

Yes please.  Me Sir, I want one.....

I'm new to all of this so this would make a great second project. PLEASE.....

Yes please....  I want one.....

Yes please, I'm just starting out so need all the help I can get !
