I just turned my CX3 into a full blown "Sonny Bird" last week. I installed both the Extreme Core and the Racing Conversion. I am really please with the results. This is totally different bird. All of the handling problems I had with the stock CX3 just disappered, "POOF". This evening I even managed to squeeze all four navigation lights into the racing canopy. After drilling the holes, it was a LOT easier than it was on the CX3 body. I love having the battery connector at the rear of the heli just like my MCX. It makes the connection a lot easier. I expect to get Sonny's motors this week. I am sure they will work well.

One thing I did find odd. I used a kitchen scale to weigh the heli after installing both the Extreme Core and Racing Conversion. I found that my heli with the battery installed weighs exactly eight ounces. That is what the stock CX3 weighs. I am using the metal stabilizer bar rather than the carbon one but the difference in weight between the two is minimal. I wonder if the weight loss mentioned in the flyer refers to the CX2?

I love my Sonny Bird!
