I have tested CKModels pro 26cc with there plane and it flys great. The Diff in the spe and CKM pro is night and day.

Sorry bill33 it took me so long. As far as the servo issue that is being posted this is totally my personal opnion. I have used and seen just about any and all servos out there. The best by far has been Hitec and Futaba servos and in Rx I would say the same. Sadly, the most $ out there is JR and I have seen more failure out of JR than any other. I guess what I am trying to say is IMO you pay good $ for your bird, so do not get chep on servos, but just because you pay lots of $ for something it still is not fool proof. Buy a servo that is the most likely going to serve you well no matter the cost. It will save you in the long run. below is what I used.

Hitec 475 on Thr
Hitec 645 on Al
Hitec 5645 on El
Hitec 985 on rudder
Futaba R319 RX

Hi all,
i'm interested as my first gas plane, into the Edge 26cc with the new Peak 26cc gas engine.

- anybody try this engine ?
- difference between peak engine and SPE ?

thanks for feedback

Mike

Thanks for the picture Freebird.

For the servos, I will buy better servos later !

Hello felows modelers!!

I live and fly here in Brazil, and have great succes with the edge 26cc from peakmodel.

Excelent flying plane, very light, plenty of wing area, a real pleasure flying it.

I have succes flying it with the peak 26cc and also the SPE 40cc, the 2 combos are good for the airplane.

I tried the SPe 26cc, but it is not good for 3d flying, i do not recomend it for 3d flying a 25% plane.

with the peak 26cc good power, with 17x6 apc prop 8200 rpm, torque rolls with 70% power.
with the spe 40cc excelente power, used 18x8 wood prop 7800 rpm, torque rolls with 50% power.

The PEAK 26cc is lighter and smother than the SPE40, realy good match for the edge 26cc.
The SPE 40 is stronger and 400 grams heavier, but is easy to balance just moving the bateries inside the fuselage, the engine vibrates a little the airframe, but realy no problem.

This is realy good airplane, the big wings and light construction can handle the spe 40cc engine , but is already good flying with the peak 26cc, below is the links to my flying videos with the peak 26cc engine, and some spe 40cc flying.

I love my edge too. I just got the 84" one. It has over 1400 Sq" area and is coming in around 14Lbs. I really like these ARF edges. I may get the big one which has 104" wing. Here is the link to the post on the 84" edge.

Thanks for that link, I've been looking all over for it. I love that 84" Edge and have been dying to read about it.

Jose,

just watched the Edge-SPE 40 combo video. Seems perfect!

Bye.

Josè,

I can see from the picture you're holding the fuse in your hands that you putted the plastic cone on the carb. Did you notice any change with and without it? Don't comes with the stock SPE.

Bye.

Hi


I put a velocity stack on my 26cc and it did help mine at high end. If you would like to get one you can get the 26cc and the 40cc velocity stack from Adam at BCMA engines. I think they where $6. Also if you are like me you would like to have a Al. spinner. Adam sell a taped hub bolt for the 26cc and 40cc. They are not much $5, both work very well. Hope this helped!

GMoneyPit, It is a great plane. It is better than I had hoped for as far as the build and looks. I am going to figure the true wing area today. Should be a real monster!

Thanks freebird1, I've got my eye on the other forum and wait anxiously for new information. I love the Edge and that 84" looks to be a fine example of one. I can't wait til someone posts some video. All the static pictures have been great so far. I can't say it enough, what a beautiful plane.

freebird1

If and when I gitter done I will take a small vid with my camra if it is not to large of a file. Now I have decided to change engines, it will set me back a bit.

Hello Andrea, i install the velocity stack in the SPE engines, they does not come with it.
I used this http://www2.towerhobbies.com/cgi-bin...?&I=LXCPB2&P=7

It improves the engine running in various situations, like knife edge flight, and it stops the fuel spraying in the airframe. (the spe engine does that, not much problem but it sprays a little fuel from the carburator).


Safe landings.

Hello!

I'm about to finish my EDGE. Putting in a ASP 180 FS. Here are some questions, maybe someone has experience with this plane can answer....
Planning to put Hitech 645 all over, or is there any big benefits to use digital servoes like the HS5645?? Will the control be better with top end servo? Any recommodations regarding thows and expo settings? Is there any couplings that need mixing to compensate?? As a to beging with, I'm putting C.G. at 120 mm aft of L.E. Is there a need for spoilron mixing to get a decent steady harrier??

TIA

B.E.

Whether you need digitals or not depends on your skill-level and flying style.

Unless you're really good, you probably won't notice the difference between good regular hi-torque servo and a digital.

In theory, a digital will give you more precision, slightly better speed and greater holding torque -- but unless you're at the stage where you're really pushing the envelope, you probably won't notice the difference and the extra money might be better spent burning more fuel so as to get a bit more practice in.

Suffice to say -- an expert flier with regular hi-torque servos will still fly much better than a lesser pilot with the fastest, strongest, sharpest digital servos on the planet :-)

Me, I still use regular servos on most of my planes -- because I'm only "average", or getting there :-)

I don't recall reading here of anyone using an OS 120AX. The one I have on my JBB turns my 17x6 APC at 9000 RPM. I see others getting fewer revs with their gassers, but is it enough to 3D it? If anyone has tried this engine, will it pull out of a hover with any authority? I love that engine and if the plane is light enough, 8-9 lbs, seems like it should 3D very well as my JBB is 8 lb 12 oz and is like a rocket ship vertically. It will hover at 1/2 throttle all day long (if only I could hold it that long, LOL, but friends of mine can :-). Let me know what you think.

Thanks,
Gary

Excellent info Jose, thanks. This gives me hope of using a OS120AX. The only potential problem I see is getting it balanced with that engine, only about 30oz.

Thanks,
Gary

hey!
recived my ARF YAK54 26cc.
i wonder what engine will be the best for 3D flying.
i heared that the 26 gasser doesn't pull out from hover well...
the 40cc looks kind'a heavy, i'm looking for the best engine setup for 3D flying.
by the way, how's the o.s glow engines work there?
i realy want my YAK light as possiable...
THANKS!

tamir_250

any help??[&o]

bill33

I have an OS 160FX with APC 18x6 and Pitts muffler on the EDGE, and it is very powerfull. No extra weight to balance.

As you are not full throttle most of the time, you can climb vertical indefintly at full throttle.

I got my edge in this weekend. I've been going through some of the hardware and am wondering what some of the stuff is used for. I have four small pieces of wood with covering on them. I'm wondering what their purpose is. Also, I'm trying to figure out how to attach the ball links to everything. Also, I can't figure out the tail wheel assembly.

Hi guys! I have bought the Edge and the Peak 26 Combo To Latvia- plane is really light- almost the same unassembled weight as my hand-made. I don't usualy buy planes, but i decided to give it a try. I red trough all posts here, and i still do not understand the Firewall and the Landing gear problem! The Peak engine looks quite cheap- like handmade- no choke, scratched piston, but rings seem to be ok! I'll disassemble the engine tomorrow- clean it (i never trust new engines- always clean them before run) Will do some polish inside if needed, and break it in. I have 1 really important question- Are really 1 Rudder and 1 Elevator servo Enough??? And do some of you use a powerbox?? I'm new at giant scale, and i would not like to spend additional $ on unneeded parts. I am going to use Graupner SMC-16 Receiver, but i'm afraid about that it could go up in smoke during flight. I will gonna be using TowerPro MG995 Servos- I i didn't really understand why didn't some of you like those- i like the power, and center- they do really seems to be good, but i'd like to know your opinion! And should i use a P-box?? And woun't it effect the working of receiver if i use the same battery to power receiver and ignition?

Thanks!
I would really appreciate some answers
Best Regards- Andrew

Don't share a battery between receiver and ignition, this is asking for trouble because it will significantly increase the amount of "noise" your receiver sees.

Don't use those MG995 servos -- I've thoroughly tested them and not only do they suffer from a large amount of overshoot (meaning they make your plane fly very poorly) but they're also unreliable. I've had four out of the 12 I purchased for test-purposes fail -- and that was after less than an hour's operation.

Is it really worth risking your plane, engine and other parts of your RC system to these servos just to save a few dollars when compared to buying a more reliable/reputable brand?

So long as you use good (ie: not MG995) servos with at least 10Kg/cm of torque, one servo each for rudder and elevator will do just fine.

You won't need a powerbox either -- just plug the servos into the receiver, use a *decent* 5-cell pack (at least 1400mAH) of 2/3A or sub-C cell-size (don't use AA-sized packs, their internal resistance is too high) and you'll be fine.

Don't expect too much in the way of 3D performance with the 26cc engine but the Edge will fly nice pattern/IMAC stuff in this configuration.

Thanks, i appreciate your answer! But rally- For Let's say Futaba, or Hitec servos- They Cost 60 Eur/ Peace, i already practicly didn't eat three months to buy the plane and the servos, and now it looks like i need to throw them out, still didn't understand what in performance of those you dind't like? And are you 100% Sure that the servos woun't burn my SMC-16 to Hell in the air? I just want to be sure to spend those $ on POwerExpander, or something Else(Suggest if you know some small P-box), because it would be dum to crash a plane because the receiver just melted. Anyways, how much Amps or Ma does the 10Kg servo use at full power?
