KO 40Mhz FM compatible receivers

[Hog]

Right - my daughter seems to be going through a phase of blowing up Futaba R123F/R133F receivers that I'm buying for her Mardave banger - are there any other brands which are compatible using KO crystals? Handset is a KO Esprit Vantage II.

Was looking at Cirrus receivers as these seem cheap to pick up?

The red hitec ones work. Cheap too.

Thanks chaps for your replies.

LRP - were these ok with KO crystals?
