Why FM radios (72Mhz etc) are not a good idea any more ?

That is an AM versus FM comparison.  My understanding is that the Ghz range is more resilient to ignition noise as compared to the Mhz range.  Would love to hear your comments on this.

Yes, GHz is more resistant to ignition noise. So, is MHz at FM.

I am with Sai on this. I would convert a MHz radio to GHz and enjoy both the worlds. The MHz receivers are going to be dirt cheap as 2.4GHz takes over. And more people fly in GHz, the MHz channels are going to be free... Buf if I change my mind to go with GHz, I can always do so anytime with my Assan module.

Thanks for confirming that.

That is just one way of doing things (assuming one is savvy enough). 

The point (of this thread, at least) is that everybody including you and Sai are shifting to 2.4.  In other words, why take the risk (of getting locked out by someone else) with a 72Mhz "add-on" ?  I am not sure price is enough of a justification for most people with a limited number of models. I think the peace of mind, security and other features of 2.4 are a better trade off.

Cost is something that has already come down for the non-premium brands, and is on the way down for the premium brands.

IMHO any beginner or even an intermediate flier who invests a lot of money in all the RC equipment would want to mess around with these things. converting AM/FM to 2.4 or whatever. I remember the time when i used to wait for other guys to land and switch off the RX. I surely hated it a lot. Now i am capable of converting a TX to 2.4 but would never do that as there is only Rs. 1000/2000 diff + a lot of trouble. only people with lot of spare time/money to waste or a RC seller/dealer would do that. BTW I am proud owner of two 2.4G  & one 272 MHz sets. Thx
