Tim Mackey Posted January 8, 2009 Share Posted January 8, 2009 yes, seems like an idea Eric - I am surprised that maplins do not stock the spare battery packs though.Andrew, it looks alike a 6 x cell AA pack ( or possibly AAA ) the plug is known as a jst connector. I have plenty of them here, and if you really get stuck, PM me and I will make up a pack for you. Quote Link to comment Share on other sites More sharing options...
andrew parry Posted January 8, 2009 Author Share Posted January 8, 2009 Cheers, i need to work out what batteries they are in the pack, 28aaa 350mAh, 1.2v each i assume. 6x1.2 =7.2vAbout 2cm long each. Any ideas, source? Its a v tight fit in the battery bay! Oh and can you get the same size but better mAh anywhere or is 350 the max? Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted January 8, 2009 Share Posted January 8, 2009 2 cm long ??????????????????????????????????????? Quote Link to comment Share on other sites More sharing options...

Tim Mackey Posted January 8, 2009 Share Posted January 8, 2009 Ah yes indeed Rob - could well be Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted January 8, 2009 Share Posted January 8, 2009 Buy em here....60 P each cell @300m/Ah Quote Link to comment Share on other sites More sharing options...
andrew parry Posted January 8, 2009 Author Share Posted January 8, 2009 cheers for the help. Does look like 2/3aaa now, got my ruler out! 27mm long, 9mm wide. Just need to source some now along with some cable and jst clip to make up some packs. Trust me to get a chinese type plane.... grrrrrr should have investigated before purchasing.

Tim Mackey Posted January 8, 2009 Share Posted January 8, 2009 I have given you the place to get em in the post above - they MAY have the jst connectors and wire too...if not PLENTY of other shops will have em. Incidentally, this shop ( component shop ) will make up the packs for you if you tell em exactly what you need. They do have packs of 2/3 aaa but not quite the shape you need - email em !

260 Flyer Posted January 8, 2009 Share Posted January 8, 2009 Timbo you're slipping! How about a nice 2 cell LiPo?For the same size you could go to 600 to 800 mAh. Quote Link to comment Share on other sites More sharing options...
001 Posted January 9, 2009 Share Posted January 9, 2009 Doesn't this plane come with a battery charger? Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted January 9, 2009 Share Posted January 9, 2009 Yes indeed, and with Andrews obvious lack of experience and equipment, I would be foolish to recommend Lithium cells.PS Andrew, slightly higher capacity ( but same physical size ) cells areavailable here too Quote Link to comment Share on other sites More sharing options...
andrew parry Posted January 9, 2009 Author Share Posted January 9, 2009 Cheers forthe advice, will look at them all.It does come with a charger, off the car battery, takes 20 mins for 5-10 mins flying time, just want more packs so i don't have to keep waiting. Mmmmm inexperienced i am. LiPo?? don't know anything about them, why is it dangerous to reccommend them at this early stage, i'm only looking for power? Going to start by buying individual cells and making a pack up, component-shop has nearly the right thing, but it's 5 cell pack with 6v grrrrr, so close, yet so far...It would be great to have a higher capacity. dimensions of my pack are 30mm w x 29mm h x 20mm d and it's a squeeze. Many thanks again. Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted January 9, 2009 Share Posted January 9, 2009 well as I said, THESE people do a larger capacity cell - buy as many as you need and make up the packs.Lithium cells require a totally different charger and care regime than the much tougher nickel cells. My advice ? - forget Lipo............... for now - otherwise ask Rob - he put you up to it Quote Link to comment Share on other sites More sharing options...
Keith Benton Posted January 11, 2009 Share Posted January 11, 2009 Hi Timbo, curious to know how you show the link as THESE and available here to. Please adviseGood advice about not going the lipo route just yet. Caould also affect the balance point of the model too.Ben Quote Link to comment Share on other sites More sharing options...

Richard Black Posted January 11, 2009 Share Posted January 11, 2009 Hello Andrew, I have just joined the forum and was directed to your posting because you have the same Maplins Sky III as me. I can't seem to get it off the ground. Does yous take off ok? Mine seems to need a huge amount of space and seems underpowered. Does yours veer to the left on attempting to take off? How do you launch yours and how much space do you use? I hope you don't mind my trying to pick your brains. Thanks, Richard. Quote Link to comment Share on other sites More sharing options...
andrew parry Posted January 11, 2009 Author Share Posted January 11, 2009 hi, Mine flys well, well it did till i overstressed the airframe in numerous heavy landings and the tailboom snapped! woops, araldite and cocktail sticks i think to repair?No tarmac near me so i throw it into wind on full power, climbs well, glides well when dead stick and easy to fly, i haven't adjusted the elevator trim either, lucky i guess.Flys slightly to the right, small bit of blu tac on the left wheel fixed that. Batteries on order so hopefully flying next week, wind dependant! Quote Link to comment Share on other sites More sharing options...
