3D > Vibe 2006

After the arrival of the kits winter of 2005/6, I was able to build up a set of twins for the 2006 season. The biggest 3D event in history, the Taiwan Cup (HTC) was held in April, so a lot of early work had to be done to have the new Vibe's ready.

The kit is very complete, and is the most ready to 3D heli offered from JR. The two models were assembled quickly with only a few changes to make them my own, and mostly, to save even more weight! I wanted the lightest machines I'd ever flown with a 90, and succeeded. Final weigh-in is 9.0lbs without blades or fuel. Some things I did to reduce the weight:

  1. Carbon tail boom

  2. Carbon arrow boom supports

  3. My own design and lighter carbon fin set (watch for new SGP item...)

  4. 2100mAh LiPo battery combined with Reactor

  5. Custom made FRP canopies weighing half of stock canopy painted!

  6. No switch harness used, only an extension attached to Reactor SW input and removable jumper to save weight

  7. Mini throttle servo

  8. Removal of rudder pushrod and bellcrank system for single carbon rod in tube.

Overall, saved about 1 lb of excess weight, and it is very noticeable compared to my prototype Vibes weighing stock 10-10.5lbs.

The Vibe is extremely fast and responsive, while maintaining complete stability. This is rare when compared to other helis with quick 3D setups which often cannot track in fast forward flight like the Vibe.

The new color scheme is designed for high visibility in white/orange/red and blue accents. Also added white trim to top of the tail boom for better visibility. The new SGP silver carbon fins reflect light better and help orientation too.

I plan to use this heli and setup for the 2006 year and beyond at the HTC, XFC and 3D Masters...
