andrew, i love the dx6i! never a frequency issue and easy to use-even for a noob like me! Rcken thanks for the advise. Don't care at all about the brand so the airtronics sound just fine if they work for you! I assume since you suggest them they will work fine with the skektrum reciever? had been leaning toward the ar6200 anyway so think thats the route i will take. you have been most helpful, If memory serves you have made several suggestions that I have found very useful and accurate! Thanks
