Making the switch to 2.4

[Hog]

Right - I'm after some advice and potential costs of making the move over to 2.4 for myself and my 2 girls.

Myself and my youngest both have KO Esprit II tranny's and the eldest has a KO EX-1 Mars tranny (all fitted with rechargeable NiMh's), so I'll be looking for 2 stick sets and 1 wheel set as replacements.

The girls have a Mardave banger and an SC10 each, and I have 2 bangers, an SC10, and a B44, so will need 8 receivers all in.

Obviously I'd be looking to sell our current 3 Tx's along with 11 (KO, Futaba and Cirrus) receivers (I have 3 spares) and around 8 sets of KO crystals as a way to offset some of the cost of upgrading.

Ideally I would want Tx's which are multi model memory rather than just single model.

Any advice on makes, models and prices would be much appreciated - and of course I'm open to offers on the radio I'll be selling

Regards,
Dave.
