Description

This is the J1S Designs "Cyclone" 505mm Carbon Fiber Flybarless Main Blade Set. R/C helicopter performance has been compromised by conventional "straight wing", continuous airfoil blade designs. Flybar blades are quick and responsive around center, but are unstable in fast flight and are prone to pitching up. Flybarless blades are stable and smooth at high speeds, but deliver a slow response around center and are more demanding of your electronics. Traditional designs make it impossible for one blade to provide both characteristics, forcing pilots to choose between crisp response around center or smooth high speed tracking in fast flight; blades that try to deliver both aspects are mediocre at best...until now!

 

Tim Jones has developed a unique, optimized airfoil design that elevates R/C helicopter blade technology to the next level. J1S Designs Cyclone blades feature an aerodynamically optimized "tapered airfoil" that allows the CG point to be configured in a way that provides fast flight stability, without sacrificing response, or "crispness" around center. The tip shape is unique and allows large cyclic inputs even at the highest forward flight speeds, eliminating the "flutter" or sluggishness that is common with heavy flybarless blades that can stress servos and reduce cyclic rates. This also allows the power system to work more efficiently and lets the blades track with one another much better, even under the most extreme combinations of collective and cyclic pitch.

 

J1S Designs Cyclone blades won’t make you fly like the Beast, but will deliver the confidence, stability, response and efficiency that will make you feel like one.

Tapered Airfoil
Traditional airfoil designs force pilots to choose between crisp response around center or smooth high speed tracking in fast flight. Using high powered CAD software and the assistance of some very intelligent aeronautical engineers, J1S Designs Cyclone blades stray from the conventional straight-line "continuous airfoil" design, and feature a "tapered airfoil" design that provides stability in fast flight, without sacrificing response, or "crispness" around center. This design has been optimized for the head speeds used on modern 3D helicopters, and allows the blade to move through the air with less drag, less turbulence and improved predictability.

 

Swept Tip
Another aspect of blade design that is often over looked or selected purely on cosmetics is the shape of the tip. Tip shape is incredibly important and has a huge affect on the lift and overall efficiency that the blade can deliver. J1S Designs Cyclone blades feature a unique tapered, swept tip design that does two things; first, the swept tip deflects turbulent air coming off the blade tip at an angle away from the disc, and away from the next advancing blade. This allows the blade to slice through the air without having to fight the turbulent air generated by the retreating blade, and produces a quiet, more efficient blade, even under high cyclic pitch conditions! Second, it reduces the "mach number" at the tip, effectively reducing airspeed and drag without sacrificing lift. This means that even though the RPM and blade length haven't changed, the airspeed at the tip has been reduced. This reduces the stress on the power system, helping to reduce operating temperatures and increase flight times! This also gives you the option to increase your head speed for more power and improved response without sacrificing the efficiency or flight time your current setup delivers!

 

Pivot Point
The pivot point of the blade affects the lead/lag that the blade experiences during flight. As the blade rotates through the air it creates drag, causing the blade to pivot rearward, or "lag" in the blade grip. The location of the pivot point is critical in allowing the blade to fly at its "aerodynamic center". J1S Designs Cyclone blades feature an optimized pivot point that helps to balance the blade dynamically, resulting in blade with superior aerodynamics, and improved in-flight stability. 

Features:

  • Designed and developed by Tim Jones
  • Uses rotary wing technology developed in the UAV/Defense industries, as well as concepts found in full scale helicopters.
  • Tapered airfoil reduces drag & increases lift. Superior aerodynamics allows for a CG more toward the root for improved response without sacrificing high speed stability.
  • Swept tip reduces effective tip speed, turbulent air & increases overall efficiency.
  • Optimized lead - lag allows the blade to fly at aerodynamic center for reduced noise and increased efficiency

Warranty, Returns & Support

Warranty Information

We truly thank you for your purchase, and when things go wrong, we are here to help in any way that we are capable of doing so.

In regards to any warranty related matter, please reference the below information to help understand our warranty policies, as these warranty policies are absolute when it comes to any purchase made via HeliDirect.

Warranty Time Frame

Regarding product(s) purchased via HeliDirect, each manufacturer has their own specified warranty time frame, and HeliDirect holds the sole right to direct the customer to the manufacturer for stated warranty support in regards to manufacturer's that require direct level warranty support.

Our stated (14) day return policy directly relates to brand new, unused products being returned for a refund or store credit, and does not relate to warranty related situations for faulty product(s). Faulty, damaged or problematic items are handled upon a case by case basis, and will be detailed below based upon the warranty options available.

Our team at HeliDirect is highly motivated to assist in every possible way regarding warranty support, but please be 100% aware that warranty support for the product(s) you have purchased may be handled directly via the manufacturer, and not through HeliDirect.

If your product(s) involve direct manufacturer support, we are still available to assist. We ask that the customer make the initial manufacturer contact for warranty support, but in the case where a manufacturer response is not receive within (5) business days, HeliDirect will step in upon your behalf, utilizing our channels to assist you with this manufacturer based support.

In the above case, HeliDirect will do everything in our power to make sure the manufacturer assists you directly, but please note that all such warranty in regards to an issue like this will still be directed through the manufacturer.

Warranty Related Issues

Please note that HeliDirect is not a warranty repair center, nor do we offer warranty regarding many items we resell. Product(s) purchased via HeliDirect are subject to the original vendor’s repair / replacement warranty policies & timelines, and will be directed to the manufacturer at our discretion.

HeliDirect will not assume responsibility and / or liability for any manufacturer defect, or damage due the use / misuse of the product(s) purchased. Further, HeliDirect cannot / will not be held liable for ancillary damage to product(s) based upon a manufacturer fault or defect. All such issues will be dealt with at the manufacturer based level.

If your item is found to have a fault or defect after installation or use, your product may be subject to warranty repair via the original manufacturer, no matter what the purchase date may be. HeliDirect does not cover repair, replacement or warranty via used / installed products. All such issues will need to be dealt with at the manufacturer level.

Damage Due to Ancillary Product Failure

In regards to damage that directly results to a failed product installed in conjunction with another product, we are happy to assist in terms of warranty support for the product that has failed, but please be aware that we cannot be held liable for ancillary damage to other items or components that may have been damaged due to the original product failure.

Warranty Returns

If your product is approved by our customer service staff as a valid return that we will handle directly, please note the below information regarding all such approved warranty items sent to HeliDirect.

- Any item(s) approved for return to HeliDirect will be subject to inspection and or testing to verify the noted information provided by the customer regarding the flaws, faults or damage.

- Due to the various aspects of testing, repair and other return processes, please be aware that any such approved return will require (2) to (5) business days for proper processing. Our staff will certainly do all that we can to reduce this time to the bare minimum, but please be aware that the return process can take up to (5) business days to complete.
