10S2PP 4200 batt, some things to know about, big size weird fit!
I got a 4200 10S2PP in, too tight! Make sure before you solder on your ends and go about getting the batt 100% ready that you trial fit it in your frame. I can tell you if I wanted to have seated this battery in my frame I would have ripped the heatshrink on the battery that is how tight it is. Just wanted to give you people a heads up on this as I would hate to see anyone out of the cash. It may be just the pack I got,,, but make sure to look at your 10S2PP really well and try it "lightly" in your frame before doing anything to it. I might be sending mine back. I measured the pack and as stated the pack was 52mm, mine was 52.347mm to be exact, I measured my frame it is 50.3.....mm. That "just over a mill" is not enough clearence to make up for my pack I got, now maybe like I said it was just my pack, but maybe TP needs to goto the drawing board again and make it stacked a tad higher and leave the width alone more to the width of the 4000mah....

Yo dude I did that allready. Let me explain what I don't like about that idea. Putting it on its side brings the top side of the battery to less than a quarter inch from the main gear, also if a o-ring breaks it is going right up into the gear, not that the high speed shouldn't be able to chew it up,, but what if?? On the 4000 pack the battery sits real low. Also another issue having this battery on its side and in general as far as center of gravity goes you have to have it quite forward on position. In fact far enough the second from the back o-ring is barely on the battery itself, to insure that if a back one came off or broke and in order to keep the battery from going into the main gear you would have to rely on say a velcro strap or something. I am not liking that...... but it will cost a good chunk to send it back so I may have to...

I guess I should clarify as per scientists comments, this battery can be as mentioned placed on its side yes,,,, is it a good fit and size pyshically for this helicopter "no". Do I feel real warm and fuzzy inside about the way it sits on the tray etc,,, ? "no"

We'll see, only thing that may save it here and me using it is the cost to send back and the dough I lost on the duty and taxes..etc....

As much as I would hate to do it... You could shim the frames...

It's what some of us had to do in the 'olden days' when some of the G1 cells wouldn't fit in the Logo10 frameset...

Oh I hear ya Pete, I was thinking of that as well. Like I had said in regards to the rockets comment, it will fit "on it side" however,,, it really is not the shiznit on fit and cg placement if you ask me. Who knows maybe the performance will make up for having to take sometime to get it in everytime for its' use. It is getting cold and settled in here, likely be awhile to try anything........Once upon a time there were Nitros, flybars and frequency pins...

I've made several posts here where i warned about the size of those packs (based on my experience with a custom made 9S2P pack of the same size cells).

I'm sticking with the 4000mAh packs for now.

i havent flown my pack yet but on its side it does fit...close to the main gear but still enough clearance.... just keep the back forward of the main shaft and it should be plenty of clearance...

also i would say use some velcor straps to play it safe... if you lose a rear strap the pack could tilt since the front of the frame is not rigid... the extra velcro would be insurance..

the advantage of this pack is power , so im told...also my 4000 packs flexed and look deformed...i doubt this brick will bend in any way...

The 4000 mah pack is rated at 48 amps continuous.

At this current, should your "full collective" actually pull this current, the voltage of a fully-charged pack would drop to a bit above 33 V. if you do the math on 48 amps/33V, you get 2.1 HP. This obviously meets/beats a 50 nitro for power with a fully charged pack.

At 50% discharge, you still enjoy 84% voltage, which probably corresponds to 1.8 HP.


The 4200 mah pack is 5% better.
