HiSKY FBL80 6-CH 3D RC Helicopter Review

HiSKY FBL80 6-CH 3D RC Helicopter Review

When I saw an excellent video on YouTube of a flybarless CP heli doing superfine 3D moves, I started enquiring with friends who share the same passion with me of collecting and flying RC helicopters about the best light CP heli through which I can learn excellent 3D piloting. They suggested me the name of HiSKY’s FBL80. I went through the reviews of this 6-CH flybarless 3D lightweight heli and finally bought it. And I must say that I am very happy with it. It is excellent for the purpose for which I had bought it – the 3D moves. It is a great fun to fly this nippy little bird which taught me a lot.

Small Size of FBL80

When seen in the videos FBL80 had looked small, but I was pleasantly surprised to see its tiny size when I kept it with my rest of the fleet. It is the smallest and shortest of them all!

Quality of Structure

To my surprise, skids of this tiny bird are quite tough. It is a question why such a featherweight heli should have such sturdy skids. Even the body frame is tough. The main rotor of the heli spins quite freely unlike V922 in which it goes on giving clicks.

Finishing

Swashplate of FBL80 is perfectly leveled like that of V922, but blades are slightly positive at 50% pitch. When I tried to make it negative pitch, the heli behaved fine on the bench heli and correct responses were given to transmitter by cyclic and collective; however, at spool the swashplate slanted towards left and blades crashed in the ground; so I had to remove the subtrim which brought the heli back to normal. Regarding transmitter finishing its buttons give clicking.  

Features

FBL80 is remarkable! Its blades (main and tail) are shiny neon green, so they are excellently visible during night flying.

Well, other feature is the receiver board of this small bird is mounted vertically, same as my V922. But looking at its structure with two screws on top, it is very likely to break first upon a crash.

Main and Tail Blades

They appear similar to those of V911. So, I think they both can be exchanged with each other in case of blades of one of them are damaged. It can be seen later when such a condition will arise. Now, touch wood, my both the birds are in good condition. The size of the tail rotors looks same as those of V922, but tail motor is smaller.

Battery

Looking at the size of the heli, the battery is obviously small but it is hard to believe that it can provide enough power while doing all the flips and rolls I wanted from the heli. But the chopper is surprisingly lively even after about 5 minute sessions of flying.

Transmitter

The tx of FBL80 is X-6S LCD and is nice to hold and though it gives loud and irritating beeps, it has several useful switches, like the one to be used for toggling between the modes of Normal, Idle-1 and Idle-2, as well as low rate/high rate. A great pitch can be produced by full collective with a pitch mix of 60%. And if we don’t do it and keep lower pitch mix, the heli would not hover at 60 or 70 percent. The tx is extremely essential particularly for learners who can decrease the rates, so that the heli doesn’t become so sensitive to inputs. Thus this tx is really perfect for them because it allows them to fine tune their bird without getting confused by the complicated setup, characteristic to a pro-level tx, like 9X having the ER9X firmware.

Flying Performance

Once the FBL80 takes off, you need not do much to keep a stable hover.  In fact, it is more stable even than V922. It gives excellent throttle response thanks to its light and aggressive throttle/pitch curve. Therefore I found it very easy to learn tail-in hover with this bird.

Flying circuits too are easy with FBL80. This is because of its light weight which means less inertia and ease in steering away from things or ground. It offers higher chance of avoiding crashes. If you are flying for the first time, use low cyclic swash mix and/or low rate. Its all movements, like moving or stopping and changing directions takes place really within no time and it goes so far that you cannot find out its direction. So, high chances are crashes or losing your dear little bird.

As the tail gyro gain is not programmable, the wagging of tail is unavoidable. It is more prominent at high headspeed. Pitch pumps cause tail blasts. However if you do flips properly, that won’t happen.

It seems like this chopper is designed specially for 3D moves! If you see its agility, quick responses and power during rolls and flips, you too will feel the same. And its ability to stop suddenly after each flip, may it be upright or inverted or vice versa, is amazing.

Availability of Spare Parts

Spare parts of FBL80 are available alright but they are quite expensive especially compared to WLToys. So, if once again WLToys come up with their copy of FBL80 as they did with FBL100, we can get cheaper parts.  

Pros

  • Strong, agile, easy to learn 3D basic moves and stable
  • More durable and resistant to damage than other bigger helis
  • Highly programmable like throttle, dual rate, swash mix

Cons

  • Expensive spare parts
  • Transmitter has no expo function
  • Manual doesn’t clear every detail like pitch and throttle curves

Conclusion

FBL80 by HiSKY combined with its X6-S tx is great for beginners with its lightness and excellent stability. The beginners of 3D are of course involved.  The transmitter being capable of tweaking rates and curves is excellent for learners to tame the nimble heli and for novices to fine tune it to their choices.
