Looking more closely at the pictures of the SX, I can't see my 4800mAh Lipo's fitting under the belt, so it looks like I'll have to get a new Lipo pack as well.

Can anyone from Schumacher confirm that only the slim Lipo's will fit?

This may have been mentioned already but I have just got back from the model shop and bumped in to Dave Foster Schumacher Rep, he confirms that the car should be here end July/Early August.

Hog I'm pretty sure that the photos with lipo in situ show the Core 5000 pack - and it's a full-height hard-cased pack.

The same height as my TrakPower 4800 saddle packs?

Here are the specs of the CORE 5000 pack,

Core RC - 5000mAHr 7.4v LiPo - Fantastic power and only 250 grams weight (NiMh = 400 gms) Must be charged with a LiPo charger. Size 137.5 x 46.5 x 23.5mm. Moulded case for maximum protection in use.:)

Ah - looks like it means I'll be selling my saddle LiPo's then as mine are 30mm deep. :(

wouldnt do that too soon, you may be able to raise the straps to get over the problem, however im not sure.. i'd still wait!

Nah I'll wait and see once the kits are out - but judging by the pics on the Schumacher site, the main belt runs over the top of the pack (or the 4 cells on the NiMh version), so I doubt there is enough clearance for an extra 7mm or so.

Plus it also looks like the battery strap pivots at the front, which again means there is no way of adjustment if it's been designed around a standard height pack.

Hey ho - not a problem :D
