original post with parts list for my AJ Slick 51 HERE
I was able to put a few more flights on the AJ Slick and work on getting the CG (center of gravity) more to my liking. It was seemed to balance on the ground well using my fingertips but in the air it was a different story and was nose heavy. Flying inverted under power with a slight up angle the plane would then drop immediately when I was off elevator. What I am looking for a is slow hesitation before the plane starts to nose over and lose altitude. This would be a good 3D setup for me. So with the two short flights I had it was flying much better than previously.
The CG range with the battery position in the Slick 51 is very forgiving. When trying different 3d maneuvers I wanted the plane more neutral or a tad tail heavy. I was at first changing the battery position in .25 – .5 inch increments which barely had any effect. I settled on a position that I am satisfied with that was nearly 2″ inches from the original start point! I’ve never had a plane where the CG range is so varied. My friend who owns the AJ Slick 70 also confirms his wide CG range as it relates to his battery position. This also confirms what a lot of owners have stated when they are flying heavier batteries and the Slicks performance and traits hardly change. With my 2600mah 4s and 3000mah 4s I’m unable to notice a detectable difference in flight characteristics. So now with a more 3d capable balancing the 51 Slick is a tumbling machine. It tumbles with ease when put into a negative inverted snap and hovering, knife edges are much more consistent. We were able to fly up to 6pm which we haven’t been able to do for the longest time were looking forward to the longer summer days.
Another Update: New Props and Wattmeter Test
I received a couple new props for the AJ Slick 51″ and installed them and ran some Wattmeter results.
1. First prop was a Wood Master Airscrew 14×8 ( MASBA1480B). This propeller was the most un-balanced prop I’ve ever purchased. Very surprising how out of whack it was. This is also my very first wood prop to try. The balancing was corrected using my Du-Bro Tru-Spin Prop Balancer and some Scotch Tape on the lightest end of the prop. This is more or a temporary fix as I would like to use clear nail polish or other permanent means to balance. Regardless the prop is now very balanced but needed a lot of strips of tape. I then added my testing battery and Wattmeter and got these crazy results. They were shocking to me being that I only went up in pitch size on this propeller. I was using a APC 14x7e that gave 876.5 watts @ 56.84 amps.
