尽管被周围无副翼应用而设计，这些刀片可以在标准的平衡翼的直升机模型，以及使用。传统的平衡翼直升机模型中使用时，他们擅长的FAI / FC3风格飞扬。
The blades is very good. Really happy with mine.Outstanding blades. I've bought 4 sets over the last year, they usually need a bit of tape to get balanced. I use them on a Blade 450 fbl and an HK 450 pro. Airfoil is pretty good, some sets of blades weigh 23g each some sets weigh 21g each, but they are always paired within half a gram of eachother (so different sets of these blades may perform differently). You need spacers/shims to make them fit on the Blade 450 grips. Each package of blades come with 2 spacers and you'll need 4 total to fit them on any blade 450.looks terrible! should be labeled C or D-finish even! finish is terrible compared to other rjx b-finish i purchased hereok I have tryed many a main blade so just wait for a full review.Excelentes palas para helicopteros de la serie 450!...Sobre todo para modelos con flybarless!The blades come well packaged in a nice foam casing. So they are well protected. They look very nice and are well painted. A real plus for the blades.
I had the balance the blade with 8cm (about 3 inches) of tape on the center of gravity. This is too much for a "high quality" blade.
I use them on a Beam E4 FBL. The overall flight is good. I had to reduce the swashplate gain a bit (other blades are radix fbl) to eliminate a slight wobbling on nick. The react good to cyclic and collective pitch inpus and give a good sound. I already feared it and, yes:
they tend to give a bit amount of roll right input when pitching (not caused by vibrations) and the helicopters oversteers when giving much pitch after a looping (2550 and 2900 RPM - 12 degree of pitch , 8 degree cyclic pitch). This show that the blades have too much of forerun/are leading too much (i can't find the proper english word, sorry!). I compared it to my radix v2 and it shows that they have about 3mm more forerun. This is too much for an FBL Blade!! and is also the reason for the good pitch input and oversteering. Sorry Hobbyking, but you have to work on this.
However: If you're not into speeding or flying really fast loops you will hardly notice this at all. It will however put more strain to your servosVery good blades, mine came wrapped well and spotless.
Really happy with mine. Must still test performance.
