Looks great Bryant330L. Let us know what you think about it. I'am trying to sell my Double Vision now so i can buy this plane instead!

RE: BME Edge?
 

I will be sure to give a flight report for you guys. We need more reports on this plane so others can decide for or against it. Thanks for the info Y N C. That eases my mind on the cg issue. Thanks for compliments also. I think this covering scheme is more exciting than the stock one.

RE: BME Edge?
 

I thought these planes were suppose to come in @ 15 lbs..............What happened

RE: BME Edge?
 

Just like every other light-weight claim made by every other manufacturer out there it is bogus. The larger ARFs always seem to come out around 10% heavier than the high end of the claimed weight range. I just wish these guys would be honest about the weight, its really not a big deal. I'm sure the BME Edge will be an outstanding performer at 17-lbs anyway!

RE: BME Edge?
 

Just got my Carbonfiber spinner and muffler in today:D

RE: BME Edge?
 

BME claim the plane is no more than 15.5 or 16lbs, but the plane comes out of the box with little hardware that came with it is 10lb 5oz, by the time you add engine , radio equiments, and the rest of the hardwares its going to be 17 +lbs. It's still a great flying plane, just a little dispointed of the weight. Maybe their scale only goes to 15.5lbs.

RE: BME Edge?
 

That's my point. You know and they know this plane will be fantastic at 17-lbs, so they might as well say its going to be 17-lbs! Truthful information will get me to buy a plane far sooner than a "light weight" claim.

RE: BME Edge?
 

:)testing

RE: BME Edge?
 

You all need to remeber that a BME 50cc only wieghts in at 3.0lbs that leaves 2 lbs for the rest of the stuff. I think it can come in at 15.5lbs with the right engine and equipment.


What engine are you guys using that came in at 17lbs ??? And what batteries ??


Chad

RE: BME Edge?
 

I have a Brison 3.2 for power, 1200 NiMH for rx and the same for ign. Motor weight is not really too much of an issue on mine because I am still tail heavy. If my motor was lighter I would still have to add weight. I don't put too much stock in manufacturers weight because they are hardly ever right. There is no way to get this plane anywhere close to the 14lbs that they have listed on the bottom end of their scale. I know mine could be lighter but it would take redoing the plane to get the weight up front.

RE: BME Edge?
 

3-lbs is probably for a bare engine. Its more like 4-lbs ready to fly (pitts muffler, ignition and battery included). I just don't see any coming in under 16-lbs, with something closer to 17-lbs the norm. Again, these planes will be awesome at 17-lbs so its not a big deal. I just take exception to false claims.

RE: BME Edge?
 

I'am not defending them , i agree that manfactures cannot tell the whole truth!! I just am fixin to order one of these and trying to get all the info i can and the best plane !!!

I was wondering if someone would mind measuring one wing half for me on there BME edge, I need the legnth and the width of the root and the tip. I'am just wanting to know the real wing area of this plane .

One place that i have found is that manafactures cannot tell the truth about wing area!! They usually include the fuse there and some even just add the tail in for good measure. When the only thing that actually flies is the wing itself ..... It is what holds the plane in the air the rest of the plane just controls the wing. Any way if some one would measure that i would appreciate it.


Chad

RE: BME Edge?
 

length of one panel---- 38 1/8" root width 20 1/8" tip width--10"

RE: BME Edge?
 

Thanks alot Bryant330L.


Chad

RE: BME Edge?
 

Hey Ptgarcia don't forget you need a engine mount for the BME. Brison 4.1lb with ignition and muffler.

RE: BME Edge?
 

Well i figured the wing area for the BME. It has 1148.52 square inches of wing area. That is not too bad. Now that is real wing area no cheating and just the wing.

17lbs , 1148.52 wing area, yikes wing loading kinda high !!!! Has anyone done some high alpha stuff with this plane yet ?


Chad

RE: BME Edge?
 

That can't be right. My wm extra 300s and Sig Sukhoi has more wing area than that and it's a small wing.

RE: BME Edge?
 

I do believe that my math is correct , are you going by what is advertised or did you measure the wing ? I have found that advertised wing area includes the fuse. As we all know the fuse does not fly the wing does! the rest of the plain just holds the wing and controls it. If i'am wrong please correct me !

Chad

RE: BME Edge?
 

Bryant330l flew the Edge today with cg at 6inch from leading edge, that's balance at the middle of the wing tube and it still very stable, hover and TR alot better too. The only thing I notice it has little more coupling during knift edge, other than that its the nices plane I had flowen so far.

RE: BME Edge?
 

Well, I got to fly mine today also. My cg is still at 5 1/2 and it is good there. The plane is very stable in a harrier. It is a really nice flyer for a plane this size. It flys a little like my 34% Extra but just not quite as stable in some 3d stuff. Harrier rolls are nice and pretty much everything else it too. My Brison gave it unlimited vertical, but it does not "rocket" out of a hover. My only real concern with this plane is the lack of rudder authority. It didn't seem like it had very much. Maybe I don't have enough servo on it. I am running a Hitec 700 on 6v, which has 161 oz of torque. I would think that would be plenty. For you guys on the fence about buying this one... I give it a thumbs up. Particleman here on rcu flew it for a little while too, maybe he will give his opinion on how it flys.

RE: BME Edge?
 

It's a great flying plane no doubt about it. Rock solid harriers, very clean walls and parachutes. Looks like waterfalls are pretty easy to do also. Even over 17lbs the Brison 3.2 was good power for 3D. As far as the wing area and weight are concerned, it doesn't mean much when the plane flys as good as it does. One issue I did notice was the fact that the plane pulled a good bit to the left on the uplines. I believe Bryant330L also put additional thrust along with the thrust built into the motor, it still pulled to the left. As far as the rudder authority, another friend of ours has a H9 80" cap, after flying it I believe the rudder authority is comparable, just something to get used too maybe?

I was kicking myself for not bringing digital camera and getting some pics and vids! Next time I won't forget it. I'll post them when I get it them.

RE: BME Edge?
 

HI Bryant300l the rudder needs more servo. I had a Hitec 5945 at 181oz at 6v and notice the rudder was lacking, now with a Hitec 805 non digital with 340oz at 6v and now fell alot better. Glad to hear someone else is flying this plane, now with more great feed back may more people will own one and make this tread more intersting.

RE: BME Edge?
 

Bryant330l just wondering what prop and size are you on that Brison? Thanks.

RE: BME Edge?
 

I am using a Fly Tec 22-8 on it. I was told that the prop was comparable to a menz but after flying it I'm not sure. I would like to have a menz to try on it. It turns it up between 7000-7200.

RE: BME Edge?
 

I talked to Max today and got one of these babies on the way to me :). I think this plane will be alot better than my DP edge. I have a DA 50 to go on it and 8411's all the way around and a 8611 on the rudder. I hope it is as good as you guys claim !! ;).

Chad

RE: BME Edge?
 

Congrats, you will love it!

RE: BME Edge?
 

Hey let not let this thread die. There a lot of new BME- EDGE owners out there. Lets here it flyers, how it flys, what it can do,best engine,best balance point,and all the pros and cons you guys can muster up[&:]

RE: BME Edge?
 

Ok, i'am having a stupid attack.

But how did you guys figure the thrust in your firewall, in other words how far back did you set the firewall back on the right side ? Do i just set the firewall to 3 degrees. Seems like if i did that that the lenght of the motor would exagerate the degrees in the firewall i would have more right thrust than i need. Any help would be apreciated. Maybe i'am jsut making this to hard ???


Chad

RE: BME Edge?
 

HI 330L; Are you flying BME Edge?

RE: BME Edge?
 

Ok , i think i got threw my attack, i was wondering what muffler everyone is using with there DA i mounted my motor and i'am going to have cut a really big notch in the bottom of the firewall to get the muffler to clear !!


Chad

RE: BME Edge?
 

330L: Pardon me for asking. Went back through the threads and saw you are flying one. You sure done a beautiful job on covering, looks real nice. How do you like the plane now since you have had some flights on her? Did you ever put 3 degrees of right thrust or what did you finally do? AIRO;)

RE: BME Edge?
 

Hi coony; Thats what I am trying to find out, what degree or no degree for right hand thrust[:-]

RE: BME Edge?
 

Well the manual says 3 deg. of right thrust so that is what i went with. Went to the home depot and a bought a protractor kinda slide thing. And i just set the firewall to 3 deg..

Wich translate to the right side of the fire wall being set back 5mm. Then i offest my motor 5mm to make the prop to be back in the center of the cowl !

I think this is right, any way this is the way i done it , I'am not to happy about the firewall having to be notched out for the muffler.


Chad

RE: BME Edge?
 

Airo,
Thanks for the covering compliment. I really like the way this plane flys. Very solid in most any 3D you can throw at it. I know very little about the needs for Imac compitetion, but for 3d this plane is a winner. My plane needs more right thrust. I glued my firewall in with no offset and I used an offest set of standoffs. Two of the standoffs were longer than the other. I think they were a standard 3 degree offset but I am not sure about that. I need to go in and put washers under one side to give it a little more right thrust. Hurry and finish yours, you are gonna like it!

RE: BME Edge?
 

I thought i would post a couple of pics of the engine mounting. I still lack tieing up some wires but you'll get the general idea.


Chad

RE: BME Edge?
 

Hi coony. I just received my edge and was trying to figure out the right thrust. So if I am reading your post right. I need to glue the right side of the fire wall back 5mm. And then mount the engine 5mm left of the center of the fire wall? And this is based on the view from the cockpit?
Sorry if this sounds like a dumb question. But this is my first plane where the fire wall and blind nuts were not already installed.

Thanks for the help

RE: BME Edge?
 

Yep you got it right. Mine turned out great , motor centered perfect in the middle of the cowl with those measurement and the spinner lined up with the cowling.

And yes right and left as you are sitting in the plane :)

No such thing as a dumb question. It's when you not sure and dont ask is the problem..............




Chad

RE: BME Edge?
 

Thanks coony for the info. I can't wait to get this plane in the air. Are you getting close to flying yours?

RE: BME Edge?
 

hey Coony; What make is your pitts style muffler on your engine?[:-] That is ashame you had to grind down the underside of your engine box for the muffler.[:@]

RE: BME Edge?
 

I have 2 styles of pitts muffler's and both had to be ground down to fit .


The one that is in the picture is a B.C.M i dont know what that is but it is stamped in the muffler. I got it off of ebay for 25.00 and i just took a gamble that it would fit one of my 50cc engine and heck it fit my DA and my ZDZ. I dont think i will use it on this plane. I think that stands for bisson cutom muffler.

Here is a pic of the other muffler. It is a SL 2123 i guess it is slimline.

It just seems that with 2 muffler that one would fit and wouldnt have to cut the firewall. Oh well just my luck at least i dint have to cut all the way threw the firwall to get it too fit.

Is anyone else worried about the top of the firewall not having any support ? Just seems that if you had a hard landing ( heaven forbid) that the downward force from the wieght of the motor just might pull the firewall off ? A hard blender or parachute might even be able to jerk the motor off maybe ? Or did i miss something there in my kit and there was suppost to be more wood to the firewall instalation other than the tri-stock and firewall? Any thoughts ?
