One of the first changes I made to the stock Radian Pro RC sailplane was to cut off the blue E3B connectors on the speed controller and solder on a new XT60. I found that while trying to disconnect the E3B that I nearly pulled the ESC out of the plane because it was so hard to pull apart.
I've switched all my RC toys over to these type connectors as I've found them to be much more reliable and of better quality than both Dean's and the E3B connectors found on the stock Radian Pro.
Made from nylon and gold plated spring connectors that are installed during the injection molding process, the XT60 gives you a solid high amp connection that is perfect for applications up to 65 amp.
I get mine off of Ebay from backbaycomputerguy. The connectors Chris sells are not cheap spin offs , but of the highest quality available and he will sell you just one or as many as you might want.
If you know how to solder, I highly recommend you try them, you won't be disappointed.

You may have read that the new Radian Pro is seriously under powered and that it has a motor problem. The Pro was advertised as having the same motor as the original Radian, just by exterior looks, this is not so. When the new motor has been run along side the old Radian motor hooked up to a watts meter, the new motor pulls 12-13 amps where the original Radian motor would pull up to 19amps. Horizon Hobby did some testing and came to the conclusion that the difference in amperage was not due to the motor but due to a manufacturing defect in the prop.
If you have a new radian and are not satisfied with the climb performance of your ship, call HH and request a new prop. In most cases this has fixed the power problem.
