SpinBlades is a company from Fassberg Germany that makes high quality rotor blades for the model helicopter industry. We were given the chance to review a set of SpinBlades 325 FlyBarless rotor blades to see how well these handmade rotor blades performed. Check inside for our thoughts and pictures!
SpinBlades was founded by Marc Trautmann and Kai Rathmann. The company was the result of Kai taking over the company Helitec in 2002. Kai’s goal was to continue to produce high quality rotor blades for all modern helicopter systems including flybarless and multi- bladed rotor head systems.
SpinBlades sent us a set of their 325 flybarless blades to test out. The blades come packaged in a protective cardboard box with small information piece of paper and blades. First thing I did was to weigh them and check their CG.
The blades show a total weight of 61 grams however the scale was teetering on 60/61. Each blades weight was almost exactly 30 grams. This weight is substantially higher than most standard 325 carbon fiber blades (Align 39 grams) , (Cermark 42 grams) but is to be expected considering they are designed to be flybarless blades and require additional wieght for the performance gains.
Blade CG was also further out toward the tips which was no surprise considering they are designed for flybarless rotor heads. I performed a very thorough and close examination of blade structure, rigidity, and quality in which I was very impressed. All SpinBlades are handmade in Fassberg Germany and have to pass many quality checks before being cleared for shipment. All lines and mating surfaces were clean and very well put together. The blades were also very stiff which I personally prefer especially for flybarless setups and it helps reduce and fluttering or play in the rotor head during hard 3d maneuvers.
Flight testing was performed on a Trex 450 Pro with the BeastX Micro Beast Flybarless System. After removing the previously installed Align 325′s no tracking adjustments were needed what so ever. During normal hovering the blades flew the same as any other higher end 325 blade on the market. Once entering forward flight and fast circuits backwards and forwards the uniqueness of the blades being made for a flybarless machine really started to come through. The blades were superior in all forward flight versus the lighter Align blades. The extra weight and outer CG made them very stable and handled excellent without showing any signs of pitching or instability. The blades handles equally as well as the others I have tested in 3d maneuvers although being heavier did slow the heli down a tad but was easily fixed by bumping up the throw for my cyclic range.
Overall if you are looking for a very high quality and high performance set of flybarless blades for your 450 size helicopter be sure to pick up a set of SpinBlades. I honestly was unable to find anything I didn’t like about them and they will be staying on my 450. The blades can also be used on a flybar machine but expect them to be considerably slower due to the increased weight. The blades retail for approx. $41.00 U.S. dollars and can be purchased directly from their website HERE.
