GWS P51 Battery Question

My friend recently handed me two packs of 9.6v 1200mAh NiMh battery packs. The batteries on are 8 AA batteries. Will you recommend flying my GWS P51 with these packs or will it be too heavy?

Currently I have the stock motor (350) and stock "C" gear on her.

Any recommendation will be appreciated.

hmm...she may be a bit heavy. And i'm not sure if it will even fit in the battery bay.

The "traditional" pack for this bird is the 7 or 8 cell AAA packs (700-1000mah nimh's) 2s and 3s lithium packs are also an excellent power pack.

it "may" work, but I don't think it will fly very well. (in my opinion anyway). As a rule, lighter is better.

Good luck

I'm flying mine with the 350 on 8.4/1000 NiMH 2/3 A & 8.4/650 NiCD AA or 2/3 AA (I'm not sure which) and it flies well on both.

That's with the 9x7 prop. I tried a 10x7 first but liked the 9x7 better.

I fly with a AA 7 cell 600 pack. It flies good, with a EPS 300 though. The cells can't weigh that much more, can they?

The battery pack fits in the battery tray perfectly. You are right, the P51 is heavier.

Thanks for your comments. This will definately save me from crashing her.

I currenlty use a 2s1p Etech 1200 with a 9X7 prop. I will be upgrading to a APC 10X7 parkflier prop. Many individuals are using this and they state it makes a world of a difference.

Thanks for the comments.

p.s. I tried the pack with my Estarter, but she was sort of slow in the air. Had to modify the compartment a bit.

make sure you do get the slowfly apc props, I ran a 10x7 APC TE, and it sucked... it would unload way too early... only pulled about 7.5 amps (great 20 min flights, but wouldn't climb worth a darn).

the gws 1080 flew better than the rest, but my pack would get pretty hot (kokam 1500 2s) and the 9070 gave the best speed, and a little less climb than the 1080... but worked GREAT.
