Thanks for your reply.
The FrSky DIY module is $27 and the 4 ch. Rx is $22 for total of $48. The WFly Tx with 6 ch. Rx combo is $47 (Futaba). The 4 ch. Rx is only $16. I fly mostly small electric autogyros and small electric airplanes with 4 ch. and short range. Autogyros has to be flown closely or the orientation can be lost very quickly.
http://www.rcgroups.com/auto-gyros-224/I am looking for quality rather than features. I just dont feel very comfortable with hand soldered tiny components. The WFly seems to be assembled on an automated process. Since WFly dont have a DIY module I will have the hack the Futaba module. The other concern that I have is fact that WFly specify an operating voltage range of from 9V to 12V. I like to use 2 cell li-ion.
Do you have any idea if the WFly Futaba module will accept +PPM signal from a JR Radio?
Do you know if the WFly Tx will actaully function below 9V? They may have specified it but I have a feeling that it might work.
Thanks
