Default LiPos to fit Corally PHi

Hi ,
I was wondering if anyone out there can tell me what hard case LiPo packs will fit the Corally RDX Phi? The clearance at the back end of a NiMh pack is minimal and with LiPos being square cased I don't think a TrakPower for example will fit. Any suggestions gratefully received!

the biggest you can get in a phi is a 3200, trakpower.
remember to get the weights

Great, thanks for that. I was hoping to get a larger capacity so that I'd not need to buy so many but I'm sure they'll still be an improvement over my rather tired 4200 NiMh cells!

Trakpower 4900's will fit - just mount it on its' side!
Stick the lead weights onto the chassis either side of where you want the Lipo to stand, then just tape it in - or mount two bit of angle aluminium on the chassis to stop it moving from side to side.
At least two of our club drivers, and I believe one of the top STCC drivers have mounted it like this and it does not affect the handling at all.
I did this originally to my Tamiya MSX MRE, having made a simple GRP bracket for it and it worked brilliantly - again the handling was not affected at all.

in that case any battery will fit, i wouldn't advise this though

Why?

Whilst it may appear 'unconventional' it allows, as you rightly state, any Lipo to fit any car. As I said in my post it does not affect the handling of the car, and I've now seen several cars running with this configuration, including my own, without any problems. With Lipo's lighter than NiMH or NiCd cells, there is not an issue with the perceived problem of weight being higher than normal, thus allegedly changing the C of G, to unduly alter the handling characteristics.
It's a solution to the problem that works.
But if you don't like this idea, then make a cradle from GRP to hold the Lipo in its' conventional position, but mounted around 10mm further out from the normal position. Whilst it overhangs the chassis marginally, again the solution works and has no affect on the handling. Again there are several cars running in this part of the world with this configuration without difficulty.
