X7FZ Down!

08-24-2019

Well, it`s been a while (July 2017) since my last crash, and today I had one. I was cutting the short grass on the edge of the runway at the flying club, and I cut a little too low. Yep... dropped it into the ground, right on the head button.

When it happened, I really thought "this is going to be expensive". But I was pleasantly surprised, when I started looking the helicopter over on the table.

The damage was very superficial, and consisted of nothing but one servo horn being stripped, and the main gear losing a couple of teeth. The main blades weren`t even damaged. In fact, the field suffered more damage than my helicopter did.... LOL. A large part of that may be due to all the rain we have been getting, which softened up the ground. But I`ll take it.

Hopefully, I can go another few years before the next one, but that`s all part of the game. I have to admit though.... that crop circle is pretty nice. ;)






Pulse Battery

I`m happy to announce that I have joined the Pulse Battery field rep team. I have been flying Pulse batteries in my helicopters for a few years now, and they have never let me down.

They produce plenty of power, and they can take whatever I throw at them. I want to thank Cong Huan Bui, for giving me the honor of representing a brand that I truly trust and believe in.



KBDD International

Hi everyone.

I`m very happy and honored to announce that I will be representing KBDD International for 2019, and the foreseeable future. I was given the opportunity to fly these rotor blades for a few weeks prior to joining the team, and I am very pleased with the performance of these blades.

I want to say thank you to Ah Clem, and Justin Aven, for allowing me the privilege of being part of the KBDD family.



Xpert KD1 servos

11-01-2018

For the several years, I have been using BK servos exclusively. I actually purchased my first full set of DS-7001 cyclic servos and DS-7005 tail servo, only a couple of days after their release in 2013. 

I have been very happy with their performance and reliability, and I am certainly not switching brands for any other reason than to try something new. 

I have been using the Xpert KD1 servos now, for about a month, and I`m kind of still getting used to them. But I am really liking them so far. One of the coolest things about them, is how they start up. When the electronics are initialized, the servos actually chime. Kind of how an ESC chimes through the motor when you plug it in.  Then...instead of quickly "jumping" to center, they slowly move to center. 

They also have overload protection, which shuts the power off to them in the event of power overload. Probably one of the most thought out part of these servos, is the ability to be unplugged at the servo body. No more unwiring the whole helicopter to change servo gears, or to do maintenance checks. 

They came to me very nicely packaged, with two different lengths of servo plugs and a few stickers. The cases they came in even have little slots that hold the servo in place. 

They are very well made, and look great too. But they fly even better. These things are fast, very smooth, and have way more toque than I`ll ever need out of a servo. I have 30-40 flights on them so far, and I`m really enjoying flying them.  As I get more comfortable with them, I`ll have more input to share. So stay tuned in for that. 

As always, Happy and safe flying. :) 

Scorpion Tribunus 14-200A ESC and HKII4525-520 motor

10-08-2017


Back in August, while attending IRCHA 2017, I purchased a couple of things for my Gaui X7FZ helicopter. Both of these items were brand new releases, and being a loyal Scorpion user, I just had to have them on my helicopter.

The first item purchased was the newly released Tribunus 14-200 amp ESC. I had been using a Hobbywing 160amp ESC on my X7FZ, and it worked great. But it was a bit too large to fit properly under the narrow canopy of the X7FZ.

The Tribunus 200, is smaller, lighter, and has has excellent data logging. Not to mention that is a snap to set up. Which I`ll get into later in this post.

The second Item purchased was the newly released Scorpion HKII4525-520kv motor, to replace my trusty HK4525-520kv motor. I know...it took me two months to blog about them. But I wanted to fly them for a while, so I could give good honest feedback about them.

So now it is October 2017, and it`s time to give my opinion. So lets begin.



The Tribunus 14-200 amp ESC:

The Tribunus 14-200, like every other Scorpion product I have purchased, was perfectly packaged in the reusable metal boxes that everyone knows and loves.

The ESC itself is finished in the traditional Scorpion gold and black, and is beautifully done. The connecting (throttle control and BEC) cable plugs into the body of the ESC, via a Futaba style servo plug. I think this is a nice feature, because it allows the user to change the length of the cable, without the need to actually cut or modify it. All you do is use a shorter, heavy duty male to male extension cable. Great Idea, Geoges. :)  Another really nice feature is an additional BEC (marked slave) output that can be plugged into the receiver or plugged into an external governor.


Setup:

The very first thing to do when setting up a brand new Tribunus 14-200A ESC is to update the firmware to the latest version. Which can be downloaded after registration is complete.

Setting up the Tribunus 14-200A ESC is very simple, and the instructions are very clear.  It took me only 15 minutes to have mine ready for the first flight. Below are a few screen shots of the setup program. I won`t get into much detail about setting it up, but if anyone wants a thorough setup explanation, Go check out Bobby Watts` video on youtube at:  https://www.youtube.com/watch?v=ioq1fXwq5vA


Here is the first screen shot of the setup software. In this tab, you can name your ESC (how cool is that?)  This is also where you set devise mode, BEC voltage, motor rotational direction, and communication protocol ( the transmitter you are using) One more feature that I think is a great idea, is the ability to set up a mAh counter in the Tribunus 14-200A ESC. You can actually tell the ESC how many mAh to take from the batteries, and it will automatically reduce the motor`s power by 50% when it reaches the predetermined capacity. No more over discharging packs because a timer was not set corre4ctly. I use a Jeti transmitter, with an MUI sensor, which does the same thing. So I have not yet experimented with the one in the Tribunus. But it is nice to know it`s there if I want to use it.



In this Tab, you set things like soft start and governor gains. Like I said, these are just screen shots to give the reader of this blog an idea of what the programming software looks like. If detailed setup information is needed. Please see Bobby`s video in the link I posted above. 

The setup software can be downloaded here http://www.scorpionsystem.com/downloads/ along with the V-Link II driver, which will WILL need to program the ESC. The V-Link II can be purchased from most online retailers where the ESC itself was purchased. It would be nice to see the V-Link II included in the box with the ESC, but the fact that is is not, is not a deal breaker.




The Scorpion HKII 4525-520 motor:

What can I say? Georges hit the nail right on the head again with this beautiful motor. This motor comes with the longer shaft already installed, and the motor can has a very unique design that I have never seen on a motor until now. Instead of just being round, like most motor, it has "scallops" I guess you could call it. Machined into the circumference of the can.( see photo below) I don`t know what they are for (probably cooling if I had to guess?) But it definitely looks nice.

Performance:

I`m not a snack 3D pilot, but even I noticed a considerable difference in torque compared to the HK4525-520. The HKII4525-520 also seems to run much cooler than my HK4525-520, but quite a bit.

My HK4525-520 ran roughly 200 degrees F, and the HKII4525-520 seems to be holding at around 140-150 degrees F after a flight.


The Tribunus 14-200A ESC stays rather cool as well. Considering I do not have a fan on it, and I rarely fly without the canopy on.


I definitely have to give the Tribunus 14-200A ESC and the HKII4525-520 motor a huge two thumbs up. This is definitely the perfect setup for any 700+ size helicopter, and will provide plenty of power even for the most demanding 3D pilot.
