I think U were asking "which", not "if".

I went w/ Powerbox. When I bought it from Dreamworks tho, Todd seemed to express a preference for Smartfly (?)

I think you need to exhaustively research both of those brands' lines of products to evaluate YOUR own needs. Lay out the features side by side and then ask Someone like Todd who's been around a long time (and sells BOTH brands) to help you decide. I find him to be honest and helpful and he actually talked me OUT of purchasing an accessory I'd called to order once because he thought it was a waste of money.

My own choice for Powerbox 40/24 competition was based on wanting to stay within the same brand after deciding to buy the RRS (redundant reciever system). I also loved the external batt warning led's, the dual batt features, the nicd/lipo switching, and the RF suppression ceramics.

Since my purchase [:@] they've come out w/ the ROYAL, which incorporates the RRS into the P-box.

Their line is extensive, the website well laid out and informative. [link]http://www.modellbau-deutsch.com/e/powerbox_systeme/produktuebersicht/start.php[/link]

I'm sure the Smarftfly folks are just as good.

It's a complex decision. Good luck!!

PS; in all fairness to you (and counter to so many opinions you'll read) I want to admit up front that I really don't know what the hell I'm talking about. But I hope I've helped you to become someone who does!!
