I am currently finishing up on my Hangar 9 Edge 540, and i just bought a Futaba 9CHP radio............. I am going to use the 9001 servos on the aileron's and throttle but dont know what i should use for the elevator and the rudder. I was thinking about using the Hitec 645's? I know that you want at least 100 oz of torque and its at like 107 at 4.8 but the speed is at like 24? will that be too slow for 3D?? I am mostly going to be hovering, etc. Plus should i use 2 servos each on the elevator and rudder?? And heres the next question, would a Brisson 3.2 be more than enough power to hover all day, and still launch er up like a rocket?? I look forward to your guys' comments............ Thanks a ton everyone is always so helpful!

In short,

90 oz on each aileron
90 oz on each elevator half
120 oz on rudder

These would be my minimums if I were foring to use that engine.....That engine will provide the power you are looking for, but keep in mind that it will also increase the wing loading so the plane will feel heavier (fly like a brick) in some manuevers

1> That engine is WAY too much power for that plane. You will be unhappy with the low speed performance (i.e. landing and setting up for manuevers) You will need extensive firewall mods and will need to seal all surfaces top and bottom. You prop clearance won't be significant and you will be eating up many props if you have any hard landings. That engine takes a HUGE prop.

2> 9001 servos are cheap standards good for a trainer but will leave you in the dirt on a high performance aerobat Use this for throttle and choke applications only!

3> 645MGs are great for 40-60 size aerobats and 1/4 scale "scale" flyers, but no good for IMAC or 3D planes like the Edge, you are asking for trouble if you use these.


If you want it to fly incredibly well and be STABLE to land -

As a minumum - Each Aileron and elevator half - Hitec 5475 HB (outstanding low cost digital servos)
Rudder (only use Pull-Pull system) Hitec 5925 MG best $$ you'll ever spend on a rudder servo

If you don't like hitec, use Futaba or JR equivelents, but expect to pay a lot more.

Only Use 6V power - either NiMH or Lio / regulated. The latter weighs less. Unless you are using a JR reciever, install regulator on NiMh battery as well.

This airplane should weigh in at around 11 pounds when finished. A Moki 180 is the perfect match for this plane. You also can go with an RCS 180 or 3W 24. The Brisson 2.4 would be at the very high end.


A lighter plane with less power will fly better than a heavy plane that is overpowered.

Brison 3.2 is more than enought power for this plane , and it ´ll do everything 3D!!!

OK............ id really like to actually talk to someone about these decisions im about to make so if someone could please instant message me on aol instant messenger th1guardian or on MSN and there my screen name is asybra00. thank you very much guys

Hey. I build my edge according to the book with a saito 180. I used Hitec 615 MG all the way around 110oz. and .23 sec. The only difference is i used 1 on eanh elevator half. Mine 3D fine. plenty of power both motor wise and servo wise. Abrison 3.2 will be enough motor, you just might be to heavy to 3D good. It might, but i dont know from personal experience. I do know for 100% sure that regardless of what anybody says on here, 100oz. is enough torque on any of the control sufaces. my .02

I also have a Saito 180 on mine with 8411 JR servo which is way more than enough servo,
I bought the servos so when I go to a bigger plane I will have them already. You can do a
search on Hanger 9 edge 540 and their is some theards allready on this plane with some good info. The 180 is plenty of power if you want to go with gas I don't think you need a motor as big as what you are talking about. You will love this plane it fly's great and 3D's good also.

My nephew & I both have the h-9 edge with fox 3.2 engines, I havent flown mine yet but he has, & it is a good 3der, just have to keep a little power on when landing, the use of spoilerons helps a little with the tip stalling. he has hitec 625s on all his surfaces & it does good so your 645s should be ok just a little slower. I have 5945 digitals on all surfaces, I know its overkill but I am getting a good stock of them to put in a 40% bird in the near future. I think all what you are planing will be ok just do some beefing up on the firewall & landing gear block. we are running 20x10 props & have sufficient clearance. I have the carbon fiber gear & it gives a little better clearance the the stock alluminum gear.
Good luck

.24 speed is a quater of a second thats pretty fast and should do good for the plane the, but the engine your using its way too much you might just pull that fire wall out. Put the 645 on the rudder elevator and both alerons and you should do fine just do yourself a favor and put a saito 180.

Sorry, but the HS 625MG's on 6 volts does just fine on my 30% Edge. If you just want to spend money for the sake of spending money, then go digital. The 625's hold up well and are plenty strong for the average person. IMHO

Ok, not to be rude but most of what i hear is all hear say, and opinions. Like i said not to be rude...... Is there anyone out there that HAS put a Brison 3.2 in there edge?? Looking at the weight difference the Saito 1.80 weighs 880 grams and the Brison 3.2 weighs 3.25 pounds, so if i have converted it right that is 256 grams per pound, making the saito 1.80 weigh like 3.45 pounds rougly which meand that weight wise it will work and will give good power........... Any replies or thoughts??

sounds good to me as long as your conversion is right

My edge with the fox weights in @ 15# dry, the fox weights 3.5 without ignition & muffler, so to answer you question yes the brison will work but it will increase the wing loading & make the plane a little more difficult to fly than if it had a saito 180 in it. But it is still managable & it will 3d fairly well. I found that most of the people here will tell you not to do it, I talked to "striker" in canada & he gave me a few tips on checking incidences & beefing up the firewall, I went ahead with it as I already had the fox & I am very happy with the outcome as I think you will be. If you are a pertty good pilot you shouldn't have any problem.
Good luck
Gil

Ps. there are 448 grams to the pound, 28 grams to the oz. & 16 oz. to the pound, the saito weights right @ 2 pounds

Brison 3.2 weights 1.474g or 52oz and his output is 5 HP
Saito 1.80 weights 880g or 31oz and his output is 2.8 HP.

Saito is lighter but less power;
Brison heavier but powerfull.

I stay with gas engine.

Here is another example of misleading horsepower figures......These engines should be judged at what rpm they can swing an identical prop.The time it takes from idle to full power also makes a big difference.The Brison may outpower the Saito,but one would not feel double the power in an aircraft

I do know one thing if you put the saito in the plane you do have to beef up the firewall or anything you also won't have to add any tail weight maybe a little if you want it tail heavy.
Iam sure after beefing up the firewall and putting that heavy engine on it you will have to add
alot of weight to the tail if you want it to stand on the prop.

Brison makes good engines and there are probably many models out there that are an excellent candidate for a 3.2, BUT the H9 Edge is not one of them IMO... The wing loading will be high, 3D birds fly best when light.

The Briton’s 3.2's all up weight complete and ready to fly is 4.5lbs... (actual weight of a 3.2 I owned)

The model will have a voracious appetite for asphalt on approach...

Below are the actual weights of several engines I owned and weighed in this size range.

OS 1.60 weighs 32ozs. Stock muffler weighs 9.37ozs., engine mounts weighs 4.25ozs. for a total of 45.62ozs.

3W24 gasser weighs 53ozs complete with ignition, mount, Pitts exhaust and battery.

FPE 2.4 gasser it weighs 54ozs. complete with stock down tube exhaust deflector, mount, ignition and battery.

RCS states their 1.8 gasser weighs 50ozs. with ignition. Probably 62 ozs. complete with battery, mount and muffler.

MVVS 2.15 gasser weighs 55ozs. Ignition??? Guessing around 65ozs complete.

The FPE or the 3W are reasonable choices for gas, IMO... 9ozs heavier in weight out the gate, less fuel capacity on board, runs cheap day after day, fuel tank on CG. There is small push for the increased weight of a gasser to a limited extent as you can carry less fuel.

FPE's 2.4 will swing a 20/10 Bolly at 6800rpm on a good day with the fixed electronic ignition, quoted by the manufacturer. 21.77 lbs. thrust.

3W's 24 will turn a 18/10 Bolly around 7900rpm, quoted by the distributor. 19.28lbs. thrust.

OS's 1.60 will turn a 18/6 Zinger at 8800rpm. 23.01lbs. thrust.

man you guys dont have any idea of how hard this will be.............. i wish there were just one answer and that would be it then noone has to worry and bam there is only one engine......... why is it so tough?

It's not tough the answer is SAITO 180[8D]
If you want to go gas I heard of one guy who used a rv zdz 40 he said it was pretty easy to set up and worked great.
