Laser EXP__Conquering The High Winds

 

A lot of people really struggle with flying in the wind, which is why in 2015 I wrote High Wind Testing__How To Survive The Elements. The advice in that article is still good, though as technology advances it became time for an update.
 
Our 48" airplanes are roughly equivalent to 1/8th or 1/10th scale. Let's call it 10th scale and keep the math easy. Flying a 48" span plane in 8mph winds is a scale speed of 80mph which equates to a small hurricane.  Of course that's bit dramatic and our planes handle that kind wind of and pretty well, but it does demonstrate what we are up against in anything but calm conditions.
 
I feel sort of uniquely qualified to talk about wind because I fly in Pinellas County, which I have read is the wind shear capital of the world. We are almost always flying in 10mph or better, and as such you sort of get used to it and develop your own techniques for dealing with it. Much of those are in High Wind Testing__How To Survive The Elements, but they are only good on a reasonable day.
 
That, and some people just can't deal with it at all, and some just get so spooked that they won't even try. You are not going to learn how to deal with the conditions unless you actually try it, but once the flags starts to stand out a little most fields become deserted. There's only one way you can help those folks, and that's to encourage them to use the available technology. More and more sport fliers who used to pack up early because of the wind are now staying later and later with the use of a good stability system. More and more students are actually making it all the way through their basic training, and doing it faster than before, because they can now fly when before they were too terrified. For the sport community this has been a really big boom.
 
Stability systems are also really good even for experienced pilots, and especially advanced 3DXA pilots. 3D planes are generally really good in the wind because they have so much control that you can fight your way out of most problems high wind can throw at you. Still, that's good fun only for so long. A good stability system keeps you in the air long after you would ordinarily bail.
 
We have too much invested in these planes to be tearing them up just because we don't want to wait for a better day. Some guys work five or six days a week, so waiting for them might mean two or three weeks. For those guys, being able to fly in the wind is essential, but now we have the answer for them.
 
For these videos I used a musical soundtrack on the first one, but the wind is ripping so hard the music doesn't cover it. In the second and third videos I just left the sound alone so you can hear for yourself what we were dealing with.
 
A bit of a disclaimer here: We are professional clowns. If you try this at home your results might not be as humorous.

When you get into really ridiculous winds, you are going to need some help, and that's also where a
good stability system comes in. Since we started testing these we have flown more and more in conditions that would ordinarily have kept us in the shop. Not only that, but as long as you pay attention to the wind direction and not get caught out down wind, you can still fly pretty aggressively in anything up to 25mph winds, and maybe even beyond.
 
I went into our ESS experiments expecting the planes to track and groove better, so that didn't surprise me. It did catch me out that a good stability system almost cancels out a lot of turbulence and bad air, and generally turns a windy day into a nice one. OK, I'm not saying go fly in a hurricane, but most people can certainly go out on days that usually keep them away.
 
Perhaps the biggest surprise for me has been that even on a really crappy 25mph day, I did not have to alter my flying all that much other than watching my downwind speed and not getting too slow. The worst thing a bad wind day does to you comes from wind gusts. A sharp blast can not only knock
you off course, but it can also either put you in the ground or make you fight for your life. With an ESS, a lot of this simply disappears. Choppy wind can really knock you around, but now it's not nearly as bad.
 
We did not intend to write windy day flying article. We just planned to go flying. I was just going out to have a few laughs with my friend Jimmy K (who also does awesome camerawork for me).
The forecast looked good, but when we got there the conditions were so bad we almost scrubbed the day. However, we were already there when the wind picked up, and we are a bit crazy, so why not give it a try? I wanted to see just how much a stability system could help, or if it would be useless in such bad conditions. It was so dicey that we wanted to keep the camera rolling, just in case it got the better of one of us.

For these videos I inadvertently selected my beloved 48" Laser. This is an incredibly special plane for me, and I sort of retired her to display when I started flying the new 52"s. She is way too good of an airplane to let sit, and I thought that adding an ESS would give her some new life. Like with my MXS seen in New Life For The 48" EXP , the Laser exceeded any expectations I placed on her.
 
I'm so back in love with my Laser that I am planning to build a 48" Extra. I always loved those planes and if it can be improved as much as the MXS and Laser have, I am all in.

 
 
 
I am going to stop short here so that people can watch the videos and make up their own minds. After the first video the conditions became even worse. In one video you will see me land and go chase after my hat, which blew off more than once. Usually you quit when it gets that bad, but you can see the plane stayed composed through almost all of it.
 

 
Now the latest two videos which were shot in bear ideal conditions. Toy can see it does not look much different because the ESS essentially equalizes the conditions.. Sire, I'm more precise and smooth in the good conditions, but the gap between that and bad conditions has been substantially reduce.
 
The message is pretty clear here: if you want optimum performance in bad conditions that ground everyone else, a good ESS is a great tool.

New Life For The 48" EXP

Thanks to all my friends and followers at Facebook for reading this article. On the first day we are closing in on 1000 views, and I am really pleased about that. Please share this with your friends.
 
 
The 48" EXP lineup has performed so brilliantly for so long and they are still deadly effective 3XDA weapons. In the rush to build and fly the latest and greatest offerings, it's easy to sort of take them for granted, but I believe that's a mistake. I wholeheartedly recommend them, especially if you already have one and some spare parts, batteries. and equipment. 
 
There have been so many cool new 52" and 60" EXPs coming out that a lot of us have sort of  set our faithful 48" EXPs aside and have flown the latest, greatest and coolest instead. This gave me the opportunity to build, fly and experiment with the new 60" Slick V2 (which, BTW, is an utterly terrific plane) and the 52" Slicks and Extras. Sadly, there was not enough time to fly my beloved 48s, but now I am getting back to them..
 
A lot of guys though, either have a bond with their 48s, or buying completely new equipment for another size plane is too expensive for them. A lot of people aren't making the move to 52" simply because they are so invested in 48s with spare servos and power systems sitting on the shelf. I faced that problem too, so I feel your pain. I asked myself what we could do to help the guys who are still trying to get the most out of their 48" EXPs and their investment in them. The answer is so obvious that it took me a couple of days to dawn on me: install an Electronic Stability System (ESS).
 
 Inside my 48" MCX 
 
 
Admittedly the 52 is always going to fly better because they have the latest aerodynamic advances and lighter construction, not to mention bigger planes generally fly better. However, with an ESS the 48" EXP can more than hold it's own with the newest planes. If you have 48s it makes sense to upgrade them and get even more enjoyment and life out of them. 
 
And, while the difference between setting up a new 48" or a new 52" is not really that much more money, if you are scratching and clawing at nickels trying to put together a killer 3DXA plane, that money makes a less expensive 48" more practical. Many times that extra $100 has made one of my projects grind to a halt, so for the budget minded, a new 48" is probably a good choice.
 
If you are switching to 52s, your 48" suddenly got a little more expendable, didn't it?  This makes it perfect for installing an ESS and learning how to get the most out of one of those systems. This is better than getting it wrong in the new plane, right? If you smash it, you weren't flying it anyways, so why not have some fun, install an ESS and learn enough that you know what you are doing when you do get a new 52" or 60"? It's also great having a plane you don't have to be so careful with, priceless, actually.
 
I was so sold on the 52s that I was going to sell off or crash the rest of my 48s and then switch wholesale to all 52" EXPs, but installing an ESS in my two remaining 48" MXS has so completely transformed them that I think I can get another five years out of them.
 
 I'm not going into brands or set up here because I already did that in Slick 580 EXP__Flying With An Electronic Stability System.  Where I am going with this article is to point out installing an ESS will make your 48" EXP fly so well that you will want to keep flying it. You might even want a new one, and I am planning to build a new 48" Extra with an ESS.
 

Old Faithful
I have two really sweet MXS that are three and four years old respectively. The primary is the plane I first tested Hitec's excellent 7.4 - 8.0 volt HS5070MH and 5087MH servos in,  and it's always been the king of badass. I later tested one of the first Xpwr 3910s in this plane, but it was so overpowered I was a little bit too afraid of it, and put my Torque  2814 back in it.

 


 

 

This plane is still in such good shape that people often ask me if it's a new plane, so I figured it is worth doing something special with. I had some graphics made up from 3M high performance vinyl, and that also completely transformed the plane that I plan to update my other MXS.  I've always love this color scheme but I wanted it to have something worthy of it being such a nice plane. I really love how she looks now. 
Flying
 
I was planning to keep my two 48" MXS anyway, at least if/until Extreme Flight brings us a 52" MXS. I've been quite enjoying them, and they are still really solid flying planes. Putting an ESS in my primary MXS so completely transformed it that I am rediscovering it all over again. The amount of improvement was so great it truly surprised me. I was ready for it to be better, but I was not expecting as much improvement  as I got. I would say of all the planes I have tested with an ESS, the MXS is the one that has had the most startling improvement.
 
The MXS has always been an outer limits performance kind of plane. but it's short coupling and triple taper wing made it the most advanced flying plane in the lineup. The performance has always been there, but you had better know what you are doing, and previously this was not the best plane for the inexperienced. With an ESS, the performance is still there, but now the MXS is about as stable and easy as an Edge, which is the benchmark of easy in a 3DXA plane.
 
If you compare these to earlier MXS videos, you can see how effortless it is to toss the plane around with abandon, and in complete confidence too.  To get supreme agility, you have to give up some stability, but with an ESS this compromise vanishes. Combining the stability of an ESS with the MXS wild character gives you the best of both of those attributes. The plane is now more stable than ever, but ESS is advanced enough to get out of the way when you want to do a violent maneuver. Basically it's still the same advanced flying, wild assed  MXS, but now she has a softer side. It's no longer a plane strictly for advanced pilots. This plane is now stable enough that almost anyone with a little 3DXA experience can jump right in and look like a pro.
 
The biggest improvement is in harrier performance. The MXS could wing rock some if you were sloppy, but again, I now compare the 48" EXP to the Edge, which is the king of harrier. You can also see the MXS is still capable if some pretty violent stuff and has amazing agility. Even rolling the plane on the deck is now easier and much less scary because the plane remains stable, and it pretty much does everything you tell it to do, goes where it's pointed, and stays where you put it. Unless you are flying in small craft warning conditions, the wind hardly affects the plane at all. We edited the first video with no music just so you could hear how bad the wind was that day, and how I had enough confidence in it to fly it harder and lower with no regard for the conditions. Essentially you don't even know the ESS is there. The airplane just feels a lot better and you can push ridiculously harder.
 
In the end, if you have some 48s, this is probably the best thing you can do for them.  A good ESS is the improvement that really makes these planes sing. I'm going to absolutely wear my remaining 48s and their equipment out, and maybe even put all my spare equipment together and build up a new 48" Extra.
