lanier edge 540 & da85

[BoneDoc]

lol, I wasn't going to get into a shouting match with them so I was just going to ditch this thread altogether. I still firmly believe that this is a 60cc plane, like the EF Yak is. With that in mind, the DA85 is still a natural choice. Once you've learned and fully abuse this airframe, move up into something more expensive. Stay cheap on the airframe upgrades and use it for what it's worth: a gas engine trainer.

If what you have is the DA50 and you're looking for an airframe, then I'd highly consider the 3DHobbyShop 85" Katana. it is easily one of the best 50cc offering out there right now, coming in at less than 15 lbs with gas built STOCK. It also can withstand a lot of abuse as my 2nd video shows

But since you've already have that airframe (and I have HAD the airframe myself), my advice was tailored to that need. You can ignore anyone who told you to ditch the airframe for something else. It' s not a bad airframe at all. It's big and it flies quite light even at 17.5 lbs. You'll need something like a 20% rudder-aileron mix and around 10% rudder to elevator mix. Other than that, it harriers great and it has a ton of rudder surfaces. My only reinforcement advice remains, reinforce the firewall.

One more thing that will make assembly easier is to swap out those wing bolts with some thumb screws (like the one Hangar 9 makes for their ARFs-- an Extra 260 or Showtime 90 wing bolts will be a perfect fit).

How about the Evolution 58 engine, anyone some experience ? it maybe a middle solution between the DA50 and 85.

[HTSkywalker]

By the way, was not able to find the Evolution website, no mention for the EVO58 GXII Horsepower on Chiefaircraft site.

Go to Horizon Hobby for the info.

The problem wiht Evo is what's your next airplane once this one is toast? For that reason a DA85 will be a more versatile option. Not to mention, DAs in general have good resale value.

[HTSkywalker]

Horizon is mentioning 8.5 HP i believe they meant 5.8 and with minor extra weight compared to the 85, what is thr reputation for the EVO engines ?

[HTSkywalker]

BoneDoc, you had a good experience with DA50 installed. will do the same, will get the DA50 and no matter what it the DA50 would always be a good value (may get the 85" Katana). I f i go up, i go 100 or 150cc size machines, this Hybrid size caused me enough headache.

Skywalker,
If time is not essential, just wait for two weeks, a friend of mine will be testing his new DA-85 on that same bird.

HTS,
I asked Zulg a fellow pilot facing the same problem in the following link to join us. You may help him guys.

LANIER EDGE 540!! WHAT ENGINE???

[Black Bird]

From what I have read, I am particularly fond of the ZDZ 80. I dislike the carb configuration on the super. A friend at the club has a 3w80. He loves the performance, hates the vibration. Anything less than 75cc at your altitude with this aircraft will be a dissappointment.

[skhalil]

I didn't mention yet that I bought the Lanier 87" edge 540, and still confused about the engine.
For now I am convinced with the DA-85 choice, but waiting, hopefully, for a happy conclusion of this thread.

[BoneDoc]

HTS, if you're still getting the DA50, make sure you get the 3" standoff, and not the 2.5" that usually comes with stock DA50. The actual distance needed is around 2.75" standoff, but you're better off with more weight farther forward. I had the 2.5" already, and didn't feel like messing with the 3".

Yep, even if it didn't work, there's always the Katana .

I would be careful not to listen to youngsters when it comes to aerodynamic advise. The higher the wing loading the less wing rock you will have. Increasing the wing loading by two ounces per square feet have small affect on stall speed. At the altitude stated, exspect a 20 percent decrease in overall performance. You will need something bigger than a 50cc.

First of all, don't pop in here as you say it and be insulting. We can have a nice discussion without you making assumptions and inciting ill will towards youngsters. I have been associated (school teacher) with many youngsters that are much more intelligent than many adults that I know. Second, I don't see where skywalker stated his altitude. Your statement that the higher the wing loading the less wing rock is non-sense.

We are not talking about pilot induced wing rock caused by overcorrecting the rudder. This happens all the time. We are talking about stall induced wing rock. The entire wing will not stall all at once and depending on the airfoil and the angle of attack the wing will go into and out of stall. This in and out of stall from one wing to the other causes the wing rock. Stall occurs when the lift generated by the airfoil is no longer sufficient to support the aircraft weight. Support the aircraft weight......that is the key here. More weight the more lift needed to support it. The lighter the plane is to easier it is to keep the plane from going into and out of stall. One pound on a 17 pound airplane can make a huge difference.

The 85 in this plane may be fine, I am not saying it would be a mistake.

Skywalker, I do not disagree with your reasons for wanting the DA over the DL. If I could have afforded the DA, I would have gone that route for just the reasons you stated. Fact is, the low cost of the DL allowed me to get into a 50CC where it was just cost prohibited before. I was willing to take the chance on the DL. If you don't want to take that same chance, that does not mean you are wrong, or I disagree: that just means you want to take a different path. Its all good.
