RE: BME Edge?
 

Did anyone get a manual with their BME Edge. Nothing came with mine. Looking for the suggested high and low rate setup. I know this is usually a fine tuned individual setting but most manufactures usually give a good starting point.

thanks for any suggestions

RE: BME Edge?
 

No Manual - you have to download it.. nice of them eh? Don't bother downloading it - its useless! I did not even look at it once.

The CG needs to be 5.5 inches or less from the LE at wing root. It flies best at 5" Put it behind even slightly

Throws in DEGREES not percent:

Low rates , 35% expo

A 20*
E 20*
R 35*


High rates, 45% expo

E 45*
A 35*
R 45*


I also did not build mine with 3* of side thrust in the firewall. I put it in straight so as to provide maximum strength in the 90* joints and used hardwood corner stock to brace the firewall and glassed over it. It is very strong. I then use throttle to rudder variable mix to mix in rudder when throttle is advanced... very effective!

DP

RE: BME Edge?
 

Regardless of how you mount the firewall, for added comfort, pin the firewall. I put 3 in each side and 4 on the bottom. I doubt that it will ever pull away from the fuse.... unless I change the engine to a turbine or something!! :D

Also, read back about the tail being a bit heavy and how you can counter it. Look at getting longer engine mounts to put the engine out as far as it will go. Every little bit helps. I think I can balance it ok now - even with a Pete Model's carbon fibre spinner on the front end. It arrives tomorrow or on Monday.

RE: BME Edge?
 

Agree on the pinning. I always use screws into the hardwood + epoxy + glassing.

RE: BME Edge?
 

The Edge finally flies! We got a decent day of weather finally and the Edge flew at long last! This edge is powered by an MVVS 58 with a custom canister exhaust, the airplane will hover at 1/3 throttle. On low rates this airplane is a *****cat. In the hands of an expert pilot it was capable of anything the pilot wanted it to do! The "Chinese Air Force" trim scheme leaves a little to be desired, but a few decals have it looking better. Also it is imported directly to Canada, shipping was very reasonable, keeping the overall cost down. Shippng bigger airplanes up from the US gets spendy in a hurry!

RE: BME Edge?
 

Looking good David.
I just have to break in the new DA-50 then mine will be ready to go. Just got the Pete's carbon spinner this past week, so break-in, then wait for the weather to cooperate. I removed the white China "stars" and added a couple of decals to spruce it up. [8D]


What was your AUW with the MVVS?

Spar

RE: BME Edge?
 

What's your weight with the MVVS 58? My with the Brison 3.2 is around 16.5lb, it was over 17.5lb at one time. It should fly alot better now, just waiting for the snow to be gone.

RE: BME Edge?
 

I think we are at about 18 pounds ready to fly, but I'm sure that if we wanted to, we could get it down to 17 pounds without too much difficulty. We have two servos on the rudder, waaay too much battery and a huge gas tank. The 58 is a 4 pound engine though. The airplane flies GREAT as it is however.

RE: BME Edge?
 

2 flights with the EDGE yesterday, all i can say is its AWESOME at 16.5lb. Frist ran of the Brison 3.2 in 7 months, no problems turns a menzs 22x8 at 7100 rpm.

RE: BME Edge?
 

Hey YNC,

Could you please post your setup to come at 16.5lbs? I think that is pretty good weight for this plane. Did you use any CF parts? if so where did you get them?

thanks

RE: BME Edge?
 

I got mine to balance at 5" CG at 16.5 pounds, but it took a lot of effort, carbon wing tube, stab tube, landing gear, spinner, tail gear and servo rails. I also had to mount everything I could on the firewall (batts, regs, ignition, etc). The pull-pull servo is as far forward as it can go (in front of the tank!!).

I ended up not liking the way it flew at 5" CG, so I caved and added 6 oz of weight to the nose to move the CG up to 4.75".. it now flies like it should. I am close to 17 pounds now... even with $300 worth of Carbon!

Had it to over again, I would have got the EF Yak. People are getting under 16 pounds with NO carbon. At $649 the EF yak cost the same as this plane and is one of the nicest planes I have laid eyes on.

DP

RE: BME Edge?
 

Ivansie. No carbon stuff. I just cut holes on the formers inside the fuse with hole saw and dremel tool.I also cut out the rudder and canopy hatch. I ues 2 1100man 6v NiCa, 1 1100mah 4.8v NiCa for ingition. 3 hitec 5945, 2 hitec 5645, 1 futaba 3001 and 1 hitec receiver. No fancy stuff. Just lots holes.

RE: BME Edge?
 

DP,

I read your posts, pretty good information. I think I am going to be doing some of the stuff you did once I finally define all the components I am going to be using. I am shooting for the lighter plane I can get and well balance without having to make any modifications to the structure other than placement and lighter components.

What pull-pull system you guys recommend? this is the first time I will be using pull-pull. Is there a significant weight difference between one or another or mainly is the horn/arms used?

YNC,

I guess you did a lot of what I dont want to do. Do you think the plane is structurally sound still?

Hey I have seen some people that changed the scheme (i hate the stock one but also did not care for the wh either). I read the covering is some off brand. What did you use to match the colors with a more "known brand"? The ones that made different trims just laid covering on top of the white base? did it work well?

Thanks a lot for your answers

RE: BME Edge?
 

Hi guys
I am thinking about buying the bme edge and 50 cc bme engine .want to use hitec 57645.on everything except the throttle will use a jr 537 on that .
This would be my first .3d style gasser i have mostly flown slymers in the 60 size .4* 60 waco bipe etc. not sure the number is roght on the servos but they are digital .
i did have a bryons aironcia champ with a g 38 but it was like a big trainer.. any help or sugestions would be most appreciated.
thanks!

RE: BME Edge?
 

I think you are better off getting the toc yak 30% or the extreme flight yak 30% just look at desertpig's post that should be enough for you not to buy the bme 540.

RE: BME Edge?
 

I absolutley love my BME edge, If i was to crash it today i would order another one. Just because of one guys bad expirence is not a reason to dismiss the plane IMO.

Chad

RE: BME Edge?
 

Coony I second that. The plane flys awesome,all most half the price of TOC and EF YAKs, and its in stock.

RE: BME Edge?
 

Just because I had some issues does not mean it is not worth looking at. I bought another one to replace my first one. The covering sucked and the instructions were useless (which set me up for CG issues) - but the structure and overall flight characteristics are excellent. This plane is very strong, as was clearly demonstrated by my 3-4 weeks of constant punishment. I was purposely trying to break it and I could not. Power dives, downward full power snaps, walls, you name it I could not break it. I finally managed to damage it while doing a set of full speed snaps to hover at a relatively low altitude (50') .. the rudder failed when the hard point pulled out.. on its descent the rudder began to flutter and the plane was heading straight toward the ground! I immediately killed the engine and pulled full elevator.. I managed to stall land (parachute) the plane without any damage to the engine, electronics, or prop. The gear plate broke off (again) and the wheels punched holes in both wings. The tail also cracked from all the flutter but all the equipment was saved.... not a scratch! Even the CF gear were still good (Thanks Graphtech!) Had I not been so low I am sure the plane would have been repairable. As is I could fix it but decided to retire it instead.

I bought a new BME Edge from a guy in Tucson (a bargain $300) and did everything to it I should have done to the first one. I completely stripped it and recovered it, I spaced the engine out fully, removed some weight in the tail, converted to a CF stab tube, used Kevlar pull-pull cables, etc, etc. I covered it the exact same as my first one.. so noone even knows the first one died! I also did a lot of beef work to the gear plate (fiberglass and balsa gusseting), that area fell apart on the first one. I also tossed the stock wheel pants and put GP Patty pants on - much better quality. I reinforced all the cowl drill holes as well.

I now have a plane that weighs 16 pounds even and balances at 4.75 from LE, that is about 28% MAC. You can really feel the 1/2 pound of less weight.

It flies a lot better than my first one, is definitely lighter, and just as strong (looks better too with a real cowl on it) I really like the way the plane flies and looks in the air. If flies much bigger than it is. As it comes out of the box however I could not live with it - it was ugly and had balance problems. If you like to tweak ARFs and customize them however, the foundation is there for an excellent airplane.

If you want a true ARF - don't want to touch it or expect it to balance out of the box without adding more weight, definitely go with the TOC or EF Yak. If you don't mind some work or you like to tweak you models , then the BME Edge is still worth looking at.

I have to say the abuse sessions are what sold me. I have never had a plane hold up like that. I now know I can fly as aggressive I want to and it's going to hold up.

RE: BME Edge?
 

Great news guys. BME will have a new EDGE coming. All MAX told me is it going to be over 2lbs lighter than the current one, will have carbon wing tube, carbon gear, carbon tail assembly, top quaity hardwares, more wing areas. will be the end of june. They also have a YAK 54 87" that is 15.4lbs with all the carbon stuff that is mentioned. Get this its $520.00 for the YAK. Can't wait.

RE: BME Edge?
 

If you want informations you have to phone MAX as its not on their website yet. BME aircraft 1-604-638-3119.

RE: BME Edge?
 

WOW that is great news and a good price.

RE: BME Edge?
 

maiden is done.
Look says it all, don't it? :D

Spar

RE: BME Edge?
 

I had the same smile after my frist maiden fly too:D
whats your weight sparhawk?

RE: BME Edge?
 

I don't have a completed weight just yet, but should be able to get some numbers this weekend.
I have balanced it an eeny, teeny, bit nose heavy, and my tank is right in front of the wingtube, so it is slightly nose heavy with a full load, but hardly noticeable. I have to run the engine in again, in the air because it came back from DA this Tuesday and they upgraded (new piston) and did some mods on it, so my initial break in has to be done over again. But, I couldn't help wondering how good this will look with a smoke system, so I can ditch some of the deadweight and replace it with a Slimline system :D!

I still have some unresolved issues with BME and am still waiting for replacement wheel pants and a canopy from Max. This is from December and it is starting to get old with them. I am not impressed that it has taken this long, nor with their policy to not break open another kit and disperse the parts to guys that need them. However, Max has informed me that the new plane will indeed have a lot of carbon fibre parts, and can only hope that I will receive new carbon fibre wheel pants for the replacement parts. Worth the wait? I doubt it, as they should have anticipated the need for parts.

It is still a very nice aircraft, but I would be on the fence about buying another until they got their replacement parts, etc, sorted out.

Spar

RE: BME Edge?
 

I don't think the wheel pants are CF but I could be wrong...

RE: BME Edge?
 

I think you are right as I just checked my last email from Max and he doesn't list the wheel pants in the CF list.

Too bad... they would look very cool unpainted, especially when you are running a Mejzlik CF prop and CF spinner.

Spar

RE: BME Edge?
 

I am stoked! My DA-50 showed up yesterday. Now I gotta list some of my old gear to get some extra bucks for the rest of the goodied I need.:D

Hi All
Here's the pics of the new BME 30% Edge 540 II.
It comes with all CF goodies, CF wing tubes. CF tail wheel assembly, CF push rods and FG landoing gear. Just like our new Yak 54. It weighs 8 lbs out of the boxes..Built-up wings and tail feather. 85 sq.in. increased on the wing area. Ultracote covered.
Priced 30 bucks less than the Yak for ARF, and USD 490 for ARC.
Available the end of July. Pre-order will be taken starting July 1st.
For all others who's flying the last version, we will carry all CF products for up-grate.
Thanks,

RE: BME Edge?
 

Wow Max! that looks sharp! I will log in to your web site for a price on the CF upgrade kit. Thanks!

Dan

RE: BME Edge?
 

That's one smart looking Edge there Max. What about the replacement parts for previous version owners? Like cowls, canopy's and wheel pants. My pants are busted up good now, running on grass strips, and a decent pair would look better when I take it to the Great Atlantic Fun Fly this July. Canopy has got some serious cracks running too.

Dan

RE: BME Edge?
 

HI guys, Ken let me fly his edge/DA50 at our past big bird, and I can say this edge is a winner!! Flew very precise (Ken did great setup) but for 3D, it was an animal, flew light, did every manuever, tip spins, blenders, rolling harriers, hover, everything was easy. Best 50cc I have touched to date!! The yak is supposed to fly every bit as good if not better Im told. Max wrung it out like a champ, cant wait to try one!!

RE: BME Edge?
 

Was that the new EDGE or the old you flew? The new one looks awesome.

RE: BME Edge?
 

had to have been the old one.. the new ones wont be out until July. The old ones fly great too.

RE: BME Edge?
 

Yes, old one, and it was AWESOME

RE: BME Edge?
 

Hey guys,

Thanks John for the complements on the Edge. This is the one John flew and it does fly sweet. It is the old one but it’s not old to me. Here is a run down of the setup I used:

DA-50R on 3 ½” stand offs, w/stock Slimline Pitts Muffler
Bisson 3.5 Fiberglass spinner, 24x8 prop
Servos, 4x5945 Digitals, 1x8611, and 2x225 soft mounted servos for choke and throttle
SWB servo arms all around
MPI Super Switch regulators and extensions
Fromeco 3x2400 batteries (Ni-Cads were in first, now replaced)
Du-bro hardware
H9 titanium links on ailerons
Central Hobbies CF push rods with titanium links on elevators
20oz fuel tank
Airtronics radio
Bevel-to-Bevel on elevators high rate 70% expo, 15 deg low rates 30% expo
40 degrees ailerons (blistering roll rate) 40% expo, 25 deg low 30% expo
45 degrees rudder high rate, 35 low no expo

Total weight came to 16.5 pounds and with the new BME CF upgrades I should be around 16 flat. It balanced right at 4.5” when complete and I am now flying it a 5”

The model was covered in Monocote. The model originally came in the teal scheme and was an absolutely fantastic covering job on the aircraft. I wanted a scale look so ended up striping it down to the bones and recovering it. I have pictures of the aircraft in the buff I can post if anyone is interested. Thanks Max for the Arc’s

I have used over 12 gallons of fuel and hundreds of landings on this aircraft and have had zero problems with the airframe, cowl, landing block, or motor. New or old, this is a fantastic airplane.

Ken

RE: BME Edge?
 

Nice job on the recover. I am undecided to do the same on mine. I may just say the hell with it and fly the snot out of it. On that note, it's good to see the Edges being sold in ARC form as well. Just noticed your setup. My carb is 180 deg from yours.

No issues with it so far, after getting it back from DA for all of the updated mods. When I bought it I asked if it had been updated, and my vendor informed that it had, but the DA work sheet says differently. Pretty new everything. I had to redo the break-in. Not enough juice through her yet, as I have been leaving it rich and am slowly coming up on the high needle, and on a NX 22x8 prop, I have it at 6300 right now.

Spar

RE: BME Edge?
 

Hi Spar,

The covering was a personal thing for me. The original covering was great but I did not care for the colors. Always wanted one is this scheme anyway. Thanks for the complements, BTW beautiful picture of yours climbing out.

As far as the motor, mine is one the first from DA with the new updates. The carb came mounted that way and since it was a new airplane there was no reason to reverse it. I am now flying it on a 24x8 BME prop.

Ken

RE: BME Edge?
 

Hi Ken I was wondering when you had the covering off did you happen to cut lighten holes on ailerons, elevators, rudder to lighten it up. Thanks

RE: BME Edge?
 

Dan Sorry for late reply.
Yes, the replacement parts, such as cowl, canopy, wheel pants will be available when the first shippment comes in on July, also the up-grade parts like CF tubes. Finally.

Aeromax

RE: BME Edge?
 

YNC,

I did not lighten any of the control surfaces. I did remove a little from the fuse but that was just to offset the fact that I put in the scale inspection window in the rear and added the bottom pilot window. Mine was pretty light to begin with. I will post some pictures of the frame if you would like tonight when I get home.

Ken
