I have 2 - 3S Kokam 1500 LiPo's that I used for my stock shogun. I was running into problems with the motor heating up and the batteries getting warmer than I was comfortable with. I upgraded to brushless w/ the Himax 4100 and a CC 25 controller. I'm not sure what the capacity of the Kokams are, but I know it won't come close to 20 amps. Would I still run into problems with the batteries heating up?

Hi there,
It all depends on what C the batteries are capable of, but if they are heating up with a brushed then a brushless is gonna be just as bad. I suggest you look at the web and try to identify what C they really are, but its sounds like they are the older 5C type. Ditch em and get some new ones, theres plenty of different types to choose from, try and pick a high C battery 10C+ as they will handle excess current draw without damage, and that will fit nicely into the battery tray.

That's what i thought. I was looking into the TP 2100's. Just wondering if they'll fit without modifications to the frame. Would I be able to use the old Kokams for a hummingbird?

for the TP 2100 you will need to buy the battery extention other than that tey work great. there were a couple of batches that came out that had swelling problems with the 2100's but i think that they have fixed those isues. Im running the TP 1320's Gen 11 with great success.

The battery extension was one of my first upgrades.

Hi Daywalker75

TP2100s fit like they were made for the Zoom + extended battery tray , I have some TP2100 packs, they fly fine for general sport flying, but if you want to go 3d'ing get a lighter pack for better climb outs. I also run Polyquest 1500s, they definitely give a more zippy vertical performance than the 2100's.

Well, I definately won't be doing 3D for many years down the road I can hover tail in and barely nose in, so the 2100's should be fine for me. Is it ok to have mini Deans plugs on them, or should they be Ultras?

What kind of times you get with the TP1320's compared with the TP2100's?

I assume you've got a 4025-4200 and not a 4015-4100 ? If it is the later definitely swap it for a 4025-3200, even if it is 4025-4200 try to swap it for a 4025-3200 with a 9t pinion. It will fit your skills better, will fly longer and your Kokam 1500s (which I personally and subjectively dislike) will stay cooler and will get you through training until you are ready for 3D.

I got a kokam 1500 with my shogun, if I get another battery, would you think a TP 1320 would be a better choice?

TP/Tanic/Irate/Polyquest will all hold the voltage better than 1500 Kokams. TP2100 3S is a popular choice for duration, TP1320 for shorter 3D (lighter pack). I am flying 4s packs but that requires external BEC. BTW check http://www.maxamps.com - he just recently got some nice 12C narrow cells, his 3s x 1650 pack should be a perfect match for Shogun.

The 4200 is in the shogun and the 4100 is in my hummingbird that I just put in. I just bought a TP 2100 3S this weekend, but haven't tried it yet.
