Ufly Hot Rod 2 or 3 Cell Conversion Kit: No Motor, 18A ESC, Rx2433 with 3 axis gyro, Digital Tail Servo, All Connectors

We have tested all kinds of FP helis, unless it comes with a belt drive or shaft drive tail design like the Ufly, they will not be comparable in terms of performance. Walkera has multiple projects and multiple teams working on different models. Unfortunately with all the politics going on at Walkera’s heavily staffed design department, the Ufly got stuck with an inferior gyro. So far the best built-in micro gyro belongs to the Rx2428 used on the 4#6 which can even hold the tail of a much larger size 400 heli. We have tested the Rx2428 on Hot rod Ufly with amazing results. When upgraded to the Rx2428, Turbo Ace 36611 and the digital tail servo, the Ufly gives you the ultimate in FP performance. The only draw back is its price. So is it worth it? The most commonly asked question is why spend so much on a FP heli, why not just buy a CP heli?

1. FP heli are easier to fly than CP due to the cone shape of the fixed pitch blades that produce more stable air current.
2. The Head speed of the FP is about 500 to 1000 rpm lower than the CP making it much safer to be around people. FP heli can be flown anywhere without intimating your neighbors. They are not scary like the CP with high head speed. Take it out to a picnic or fly it in a parking lot while your wife does her shopping and you no longer panic when kids start to chase it down.
4. FP is easy to maintain, balance and repair because the head design is much simpler.
5. FP is cheaper to crash and less likely to break in a crash compare to CP.

Why would you purchase a CP when you don't need 3D. FP is designed with much more stability and control for sports flying.
For years older FP designs have always relied on sluggish and heavy motorized tails. Only with recent advance are FP designs able to fly in windier condition. Developed and refined over several preceeding models, the Ufly’s shaft drive pitch tail  has overcome all these issues with its quick and precise controls that is also easy to maintain. Thou the idea is on the right track and Walkera has all the gyro technology, the Ufly has ended up with inferior electronics, it has adapted the wrong receiver with its weak built-in gyro. In addition the Ufly should have adapted the faster digital tail servo. In order to obtain the best performance, the stock Ufly receiver must be replaced with the RX2428 or the RX2609 which have the superb integrated micro gyro technology. By implementing the combination of best components available, the Hot Rod Ufly is the ultimate in FP design today. Upgrade kits are available in 2 or 3 cell version and if you chose to purchase a turn key custom Hot Rod Ufly without doing any of the modification yourself, it is also available at
