Call me old school, but as far as I'm concerned, it offered the perfect match of size , weight, and power for the average person who is looking for a nice size electric powered RC helicopter. If that sounds like you, please do keep reading It also works extremely very well for "Stretch Scale Builds", ie. Because they use torque tube tail drives, customizing the boom length is fairly simple.

First, there is no unsightly anti-rotation bracket that has to stick up through the dog house the top part of a helicopter where the rotor mast exits.

I got my first Trex ESP back in In the ESP was discontinued by Align leaving many of us shocked and annoyed! I did purchase and build a 12S powered Align Trex E Pro in ; but to this day, I don't enjoy flying it nearly as much as the 6S powered ESP version, and it's not nearly as good a set of mechanics for scale builds. I found what looked like a decent ESP copy by VWINRC link takes you to my review on it , but they went out of business shortly after I got it and I've been searching for a quality replacement ever since.

Not only for kits, but for parts as well to continuing servicing my fleet of ESP's. I discovered the Phoenixtech ESP version in , contacted them, found out all about the company, was very impressed, and even though I'm not a fan of clones, I decided to become a dealer after I got one to build and try out; that is how much I liked it.

Again, it was never to offer a cheap copy of a great helicopter! I knew there was a fair amount, but the questionnaire really confirmed it as I had nothing but lots of positive feedback on the idea. First up, here's an unboxing video so you know exactly what you'll get with the kit and get to see the overall quality of the parts.

Parts quality is very good and I really have no complaints as everything went together as nicely as my Align ESP's. I had to shave the little plastic nubs a little smaller but I suspect most builders wouldn't even bother to go to that extra effort and still get a decent fit. As I mentioned in the unboxing video, there are no instructions, but you can find Trex ESP's instructions here , and I also have made a set of ESP build videos which are on the sales page , if you wish to watch one of these Phoenixtech kits going together.

Shown above is how good the main rotor blade balance was out of the box on the Dubro Balancer; so they do certainly seem to be good quality blades. That said, I still recommend checking the blade balance - just as I would recommend on any heli build. Much of the kit is pre-assembled loosely , so you do have to take it apart one section at a time when building it.

This has pros and cons over having all the parts in separate baggies. I really don't find either way is better, just different. What I am getting at here however, is you do need to take it all apart to insure it's put together correctly, fasteners are clean, tight, threadlocker is used, and all thrust bearings are properly greased.

Nothing that you should be omitting on any RC heli build regardless of the manufacturer in other words. If you needed any of these Phoenixtech ESP parts for an existing Trex ESP, you would have to get all of them and your frames would then be spaced 7mm wider.

At first I was not too impressed, but I soon found out this was a blessing in disguise as the size kv motor I ordered for it would have been too wide to fit into the skinnier Align ESP. With many size motors now being in the mm diameter range, it's very nice to have that extra width as it opens up more motor options both for 6S and higher voltage setups should you wish.

This will make mounting this ESP a little bit tighter up top in some fuselages if you are getting one for a scale build, but they will fit. With this wider ESP version, the front top corners of the frame will likely have to be ground down slightly; or simply sit the mechanics a few millimeters lower in the fuselage, but other than that, the fit is identical.

By the way, the canopy mounting pins for the Phoenixtech ESP are 3. Speaking of canopies, I also received a good amount of questionnaire feedback stating there was a lot of interest in kits without the canopy if there was a cost savings. These people either already had ESP canopies or of course don't need them for a scale build. The only other item that is not exactly the same as the Align ESP is the length of the tail rotor pushrod.

This means the tail servo sits a little further back on the boom even when you rotate the servo around so the output shaft is closer to the rear of the helicopter as shown below. By the way, just like on the Align ESP, all pushrods and link balls in the kit are stainless steel.

Yep, many lesser quality clones suffer from drive gear quality and it has been my experience many are out of round to the point you can't use them. Even Align's ESP gear sets suffered slightly from this, but certainly not to the same extent. I'm happy to report Phoenixtech's gear sets seem to be just as good as Align's. The kit also comes with a 15T alloy pinion which was very nice and exactly like Align's 15T alloy pinion.

All main drive gears by the way are straight tooth, not slant tooth so they are direct replacements for the Align ESP's gear set if you needed to get spares for your T-Rex ESP. The carbon frames on the Phoenixtech ESP are 2. Another really interesting option Phoenixtech gives us is the frames are milled to accept a third bearing block for the main mast located directly under the gear set, just like on the Nitro version.

The kit doesn't come with this third bearing block from the factory, but is a worthwhile part order and install in my opinion if you fly hard. This 3rd bearing block option is what really sets this ESP apart from all others including Aligns' , and is just one more reason why I'm so impressed with these kits.

There's no question all ESP's when flown hard, can experience main shaft flex under the lower bearing block and this can over time, cause the autorotation one way bearing to seize or even cause the main gear teeth to strip out. The seized bearing problem actually has happened to me on one of my Align ESP's.

I documented it on my RC helicopter crash page before I knew the real reason behind it. Fitting the 3rd bearing block under the main and autorotaion gears essentially eliminates lower shaft flex while increasing overall frame rigidity and reducing the possibility of a stuck one-way bearing or stripped main gear.

Definitely a beneficial improvement to add some extra skookum factor to the overall design. As you can see above, the main mast is also slightly longer than the original Align ESP one to accommodate that optional bearing block should you wish to use it.

These Phoenixtech ESP kits as shown in the unboxing video are "bare bones", meaning they come with no electronic components. Most folks looking at this level of RC helicopter and by the questionnaire feedback I got want to pair their own electronics and that is why I'm not offering a specific electronics package with them. I did something different with this build however as I wanted to offer at least one budget minded electronics package suggestion that will work well.

I had an older Align 3G unit in my parts box and I figured that was a good choice as I'm very familiar with what the Align T-Rex ESP flies like with that unit; so I figured this would give a good "apples to apples" comparison while flying this They have certainly exceeded my expectations considering the low costs. It is unfortunate Rotor Star stuff from HK is getting hard to find. The motor is insanely powerful and to be honest, I have never flown any 6S powered size helicopter to date with as much power as this thing can put out.

The only potential draw back with this motor is it favors power over efficiency. For scale it may not be the best all round choice, but for sport, it's great! I'm not certain if my ESC choice is best at only A even though it is running cool. I know I'll never get there the way I fly, but if you wanted to play it safe, I do recommend going a little higher. Now, I'm not saying these are the best lower cost pairings to install into your new Phoenixtech , but I did want to let you know about them as they are working very well in mine and I did at least want to give you some lower cost options for an electronics package from a popular online hobby source many of us are familiar with worldwide.

I'm not going to recommend a specific flybarless system for the simple reason we all have very definite opinions on what FBL units we like and don't like. I've been very happy with the Bavarian Demon 3X in all my recent builds, but to try something different, I just installed the Ikon2 FBL unit on my ESP, and have to say it just might be my new favorite! What a great system for the price Put whatever FBL unit you like in it. I would go with nothing lower than 30C and if you fly fairly aggressively, at least 35C and up.

Lastly, this ESP doesn't have to be 6S powered if you don't want it to be thanks in part to the wider frame spacing for various motor options. It would have to be a fairly small capacity LiPo pack with 12 cells for it to fit and not make the bird nose heavy. In some scale applications however, 12S would definitely be doable as there is so much more room up front in many of them. Predicable, stable, non-intimidating, economical, easy to see, easy to live with, decent flight times, likely won't strip your servos out with a minor blade strike, and fun to fly!
