Tony j Posted June 14, 2020 Share Posted June 14, 2020 Hi all Hopefully a nice simple one. I have just completed an acro wot artf IC version plane . I need to fit the rx battery I am wondering where others have positioned their battery in this model . Many thanks. Tony J Quote Link to comment Share on other sites More sharing options...
Cuban8 Posted June 14, 2020 Share Posted June 14, 2020 Hopefully a nice simple answer.................install the battery in a position that gives the correct balance point (CG) location according to the instructions, or at least in a position that reduces the need for lead ballast. Not in the engine bay - too much oil and crud. Usually as far forward in the fuz near the fuel tank. Goes for most IC tractor 'planes. Had an Acrowot from a kit for years as my hack model.............never bettered! Hope you've got a decent engine, they like plenty of grunt, but can be flown gently when the mood takes you. Just a thought......Even the old kits had a weak undercart mounting and I think the ARTFs suffer from the same thing but only worse. If your field is in any way a bit rough, it'll be worth adding some reinforcement. Edited By Cuban8 on 14/06/2020 10:00:16 Quote Link to comment Share on other sites More sharing options...
Richard Wills 2 Posted June 14, 2020 Share Posted June 14, 2020 It will depend on how heavy a motor you have, mine has an OS 55ax engine, and an 1100mah life battery next to the fuel tank balances spot on Quote Link to comment Share on other sites More sharing options...
Tony j Posted June 14, 2020 Author Share Posted June 14, 2020 HI Thank you for your comments both You have a good point there Cuban 8 about reinforcing the under cart section. I will look at that. Richard when you say you put it next to the tank did you mean at the side of the tank in the same section because that is about where I reckon I need it to get balance . Many thanks Tony J Quote Link to comment Share on other sites More sharing options...
Chris Walby Posted June 14, 2020 Share Posted June 14, 2020 My Acrowot has a Laser 70 in it, no lead and the RX battery goes underneath and in front of the tank. I use a 3S800 lipo and an external electronic switch/UBEC. I made a hatch up out of the weird bit of fuze that can be cut out for electric or something (couple of dowels and hatch catch). I started off with the battery in the fuz above the wing and lead in the cowl, but after moving the C of G to the published figure (started forward), I just moved the battery forward and dropped the lead. They fly super nice, hope you are impressed with yours. Quote Link to comment Share on other sites More sharing options...
Martin Harris - Moderator Posted June 14, 2020 Share Posted June 14, 2020 Keeping the weight as low as possible is always best for ground handling - less movement as it pitches... Quote Link to comment Share on other sites More sharing options...
