Hi

I understand you are after a 35 Mhz receiever but I will just inform you that I have been flying a Futaba FASST 2.4 Module in my Graupner MC24 since october 2007 in two different F3A models, one with electric power and one YS 170 power. This has worked perfect with no issues at all in both applications (even with carbon canopies and so on close to the Rx)

The transmitter is slightly modified (just a opening for the antenna in the rear cover) to accomodate the Futaba module, and you also need to make a small electronic adaptor because the Futaba and JR PPM signals are inverted relative to each other and also has different amplitudes. All you need is a transistor and a few resistors, easy to do with basic electronic skills.

I am very happy with my MC24 "mid life update", now I can live with it a few more years......:-)
