Comments on: Reparing the Super Cub Battery Box http://thesmithfam.org/blog/2006/11/12/reparing-the-super-cub-battery-box/ Your blog is probably better than mine.

Someone else suggested using 2 rubberbands (looped through the battery box) and attached to the same posts that hold the top wing in place which seemed like a good idea. I took it one step further and attached a rubber band around each wheel strut (up near the fuselage) and attached the other end to the respective front posts. I tried it today without the battery box popping out and the wheel strut stayed in place. It could have been my lucky day but it is worth a try.

I found the cub flew much better without ATC. Just be sure to turn it off on your transmitter too. Personally I disable the ATC by unplugging the sensors completely.

Does anyone know if it makes a difference how you connect the two sensor wires (for ATC)? After switching the connections back and forth I had a hard nose first landing which means the ATC wasn't working. I had the battery box fall out of my Super Cub too.

I'm really just parroting what I've read online before about the jumper.

It will make the cub fly much much better! I used the Elite 1500mah 8-cell pack from cheapbatterypacks.com, and it was fantastic. Also, you can use li-po batteries, but you have to cut the battery box to make room for them, since they are taller. Also, there's a jumper on the receiver box that you have to move to tell it that you are using li-po batteries so it sets the low-voltage cutoff correctly. Good luck! --Dave Definitely go for the 8-cell NiMH pack. It will make the cub fly much much better! I used the Elite 1500mah 8-cell pack from cheapbatterypacks.com, and it was fantastic.

May I ask, is there any danger to putting bigger battery packs in? Like a li-po 1500mah? 2500? Unfortunately I just bought 3 of the Hobbyzone 8 cells. But I'd like longer life, and maybe more power. Thanks for any comments, if this is not too old.... Jim Neat job, I’ve filed it away for when that happens to my new Super Cub. May I ask, is there any danger to putting bigger battery packs in?

More amps simply charges the pack faster. The important number is the voltage cut-off. When packs charge up, their voltage goes up a bit. The charger monitors that voltage to know when it is done charging. If the charger is not sensitive enough, or is hard-wired to do 8.4V (for 7 cells), then it won't fully charge the 8 cell pack. Some chargers are smart enough to detect the starting voltage and know how many cells there are. Others have to be told with a switch by a human. Some chargers will even automatically reduce the amperage as the pack charges, so they don't over charge it accidentally at the end of the charging process. Someone correct me if I'm wrong, but I think the field charger that comes with the cub is just very simple and hard wired for 7-cells, so it'll never fully charge an 8-cell pack. --Dave Stan,

Maybe someone reading your blog might have an idea on a question I'm running into..?? Bought two 8 cell 9.6V battery packs for the Cub. Then read where the 12V DC peak charger would not totally charge them at the 1.2 A setting. This is the field charger that came with the Cub. Hunted around and found a field peak charger at Hobb-e-Mart that is supposed to handle everything from 5 to 10 cell packs. It was marketed for the "ParkZone" type of birds that HobbyZone sells. The Amp settings on the new charger go from .5 A to 1.8 A. The question I can't find any info on.... what Amp setting does a 8 Cell 9.6V 1100 mAh need to peak charge..?? I'm assuming it has to be at least in the 1.4 to 1.6 A rating. But that's just making a wild guess. Dave…
