Should I switch to dx3r??

[bl-is-future]

Thank you all for you input it has helped me along the way. I have decided on futabas fasst for sure but looking at this radio for now. http://www3.towerhobbies.com/cgi-bin...?&I=LXPZT7&P=0
Cheaply priced and comes with 1 rx and i will buy a second rx at the time of the purchase.
Only question is will i be able to use the rx's from the 3pm with the 3pk or 4pk because if i find one cheap enough i will buy that later on. If they wont i might as well just go with a 3pk with only rx for now. Just dont need all the goodies a 3pk has but down the line when money is better it could be nice. Thanks
