| Quad rotor heads + release dateHi All, I'm the developer of the SK360 Digital Flybar.
Final dimensions are 40x30x15mm, and it can be mounted in almost any orientation. Weight is 20 grams.
The gyro can be set up with or without the USB interface (included), but you'll get better results if you use the interface. Most tuning can be done at the field, using just the two built in gain dials. It can use analog or digital servos, latency is just a few milliseconds, and end-to-end precision is 12 bits.
Production is underway and it should be available before the end of March. Price will be less than half that of the v-bar.
Re multi-blades: I just finished testing it with a quad-rotor head on the Trex-450, and after getting the phasing right, it flies very well. The popular low-cost quad head used needed some work though, to get the vibration down from "paint mixer" to "Amsterdam special" (Quads turn out to be 2x as hard to set up as twin blades. Who knew).
The quad Trex has a very solid feel in forward flight, tracks like its’ on rails. It will also hover hands off for about 10 seconds in gusty wind, which is about normal for a flybarless heli with the SK360.
The SK360 has flown a blade cp, x400 (mech mixed), Trex 450 (many configurations), Mini Titan, and Logo 500. Testing is still underway on 30 and 50 size nitros, and the Trex 500. No problems are expected, as it has flown for 6 months and hundreds of flights in many setups, good and bad, with few problems. The rule seems to be that the bigger the rotor disk, the easier tuning is. The Logo 500 for example required no tuning at all from the "starting point" settings.
Mechanically most helis can be converted to flybarless with existing parts, but using a zero-slop swashplate and digital servos really helps. A trex-450 can be converted in about 30 minutes. We will provide instructions for easy conversion of the trex and others. The ideal would be for flybarless heads to be provided for the popular models, but it might take them time to catch up.
When the gyro is available, a link will be provided through a Runryder advert to the website.
Thanks,
Bruce |
