Is there a dimensional or size restriction to the lipo packs that you can run in the RC28? Anyone have a clearance issue with the rear shock?

Stock hold down meant for hardcase lipos up to 20mm wide. The larger capacity batteries larger than that won't fit without aftermarket battery hold down solutions. Rear shock wise if you use the stock hold down it's fairly standard for this scale to have to un-screw one end of the upper shock to clear battery removal or use alternative aftermarket options.

what receiver are people using with their flysky radios? there are a couple different one with different brands out there. anyone fit on the chassis better than otheres?

so did anyone run that in races against RTA or RX28?
