Tks Mike      nothing in particular just tobrowse around I suppose. Is it a craft shop or a r/c shop?

I am going to visit Cambridge over the weekend. Are there any model shops in or near C? 

Thanks for all your contributions ! I John Cole gave one of the reasons for discharging ; to bring a fully charged battery back to a fit state for storage among others. It was interesting to see the reaction and interest of subscribers to the other web forum, linked by Bert, where  the same basic question was posed .                    But then the solution was elegant.

Phil wood thanks I would need to ensure that the voltage in each cell does not fall below 3v. I have been wondering if an esc or a voltage regulator could be adapted. Some of the newer esc's from HK have individual cell protection as well as the overall limiter Bert....... thanks...... very intellesing...... I am thinking about it 

Ken..... no........ always ready to sit at the feet of master and learn Timbo....... you have hit the nail on the head !  That's why I am looking for a decent circuit. I have an I max with a discharge function which is inadequate.                 The "E" in RCM &E used to mean something not any more!  .  

Steve, tks:           obviously one of the uses would be to discharge my lipo's.What do you use and how long does it take you to discharge a 3300 ma. li-po ?  Bert thinks that discharging batteries is a waste of time.  Is it?

Bert  ..........why do lipo chargers have discharge functions if its not necessary?

Thanks steve what would you recommend?

Can any one suggest a circuit diagram to discharge li-po batteries safely at up to ,say, 3amps and a minimum safe voltage of 3v. per.cell. I use batteries from 500ma 2cell to 3300ma 3 & 4 cell.

Tom Bailey here is a copy of my recent e/m to magicalia. as yet no response. reminds me of the old saying about hens teeth. so what about the free gift?

Danny: the review is on this website listed under engine reviews. The reviewer was not happy with the "feel"- took the rocker cover off and heard a mechanical click. Reassembled it with no further adjustment and it felt normal .

Tony Patman, Danny Fenton sorry I seem to have lost the thread! My note should have been addressed to Tony P.

Danny Fenton Re SC30FS A review of this engine was published in RCM&E Jan 2007 P.74. You may have seen the article already but the reviewer describes the engine's starting difficulties which he overcome by fitting a larger 10 1/2 X 5 Bolly glass nylon prop. There also seemed to be an assembly problem with the review engine

Thks the tea will recharge anyone's batteries

As a potential revivalist I am tempted to start again with electric flight. I cannot however visualise the kind of kit that I would need on the flight line for say two hours flying in a day.At one club I saw the only electric flyer with his own portable generator to charge batteries. Is a generator essential? if not how many battery packs would I need to take for say a 40 size trainer and how are they recharged at the field? Would I connect a dc charger to my car and if so would this drain the car battery? The carpark is some distance from the flight line so do I trip back and forth with one battery or what? Tell me please how the electric experts manage their logistics
