Wild Hare Edge 540t set-up plans
 

I have recently ordered the wh edge 540t "all white", wanted to know what other people planed on using to complete the plane. I plan on the following:

BME 55 extreme.. I called them, and they said it will be available in January... 2LB WOW
DA 50 if the engine is not available by early next year.
HT 5645 all around except trl and choke
1 rudder ???????
Pull/Pull rudder
1 Futaba PCM RX
2 1800 nmh on rx
1 1200 nmh on ign
I may go li/po but I am not that familiar with them.. It really depends if plane's weight is as per stated on WH site
2 switches...... what are the best switches?????
I will probably order the hardware package that is offered by WH. Sounds like it is great quality, and price, not to mention convenience.
I am also looking for some good pics of color schemes that would be easy to duplicate with the all white covering coming on the plane.
My last question is concerning the kill switch set up. What is the lightest most reliable set-up out there? Can you just use the choke as the only kill?
Please let me know what your plans are, or if you see any problems with mine.
I would also like to say that Wild Hare as been a GREAT company to deal with so far. The owners of the company, Tom and his wife (I assume) are very knowledgeable and friendly on the phone...... YES, they answer the phone.
If the plane is as good as it looks, and the specs are close, this will be only the very beginning of me owning WH Planes. Thanks Tom if you are listening.

RE: Wild Hare Edge 540t set-up plans
 

Yes, I'm listening, and thanks. I'll try to answer your questions, but keep in mind that opinions are like, well, everybody has one.

I 180OZ servo is fine for the rudder unless you want to fly JOe Hunt style, then you will probably want two. There's a way to do 2 on pull-pull without modifying anything.

Unless you have a need to fly 7 to 10 times without a recharge, you're loading it down with more battery than is necessary. Ignition does not need more than a 600mah pack to fly for 90 minutes at least. You can use half that amount of battery if you have the ability to recharge at the field or if you only fly 3 or 4 times like I do. Why carry more weight than necessary.

The 5645s are good stout servos but they don't center as well as the more expensive 5945s.

The Maxx products charge jack switches fit in the pre-cut holes in the fuse and I've never heard of one failing. They seem to be a good product.

ON the prototype that is in all the pictures I use a choke servo which doubles as a kill switch. It needed some nose weight anyway, this is simple and effective. I have included a photo of the throttle and choke servos with a DA-50.

Edge540TS:

Here is my line up, so far:

HiTec 5945's all around.

Fromeco Relia-switchs (These are solid state electronic switches that power in the 'on' state if they break. No slide switch, but rather they use a 'pin' with a flag that you must remove before flight in order to turn them on.) (Guess I have to cover the pre-cut holes.)

ElectroDynamics Fiber Optic Kill Switch

EMS/Jomar Glitch Buster (Optical Isolator that isolates the servos from the receiver and allows the Rx & servos to use their own power supply.)

NiCad 2400mAh pack on servos. NiCad 1400mAh on Ignition. NiCad 800mHa on Receiver. (I fly all day.)

Receiver is Multiplex IPD technology (9 channel). Transmitter is JR 8103. (Unless I get a Multiplex Royal Evo 9 for xmass.)

Engine is a DA 50R.

And I may use two (2) Fiber Optics from aerographixs if I chose to put the throttle & choke servo on the motor box. Reasoning is the DA 50 is light and I need the weight up front if I choose not to use a pull-pull on rudder, but rather a push-pull on the rudder and have the servos mounted in the tail. (All depends on balance..)

Hardware is Rocket City.

Also I make all my own 22 gage wire extensions.

That's about it...I want one with the color scheme on it. I happen to like the design, some don't. It's all opinion.

Sure hope they ship state side by Thanksgiving, I'm more hungry for the plane than the bird.;)

Let's hear from you other guy's & gal's on what your plans are...

RE: Wild Hare Edge 540t set-up plans
 

I have one on order and I guess my plans are simple.
Looking for an engine now.
using Hitec 5975 servos on elevator and aileron.
using Futaba 9303 on the rudder.
using either Hitec 605's or 422's for throttle and choke.
Using tom's harware package
2 1400maH Nicad packs and HD switches from Radical RC
1 2700maH pack for ignition.
Gotta contact my builder to assemble it :)

RE: Wild Hare Edge 540t set-up plans
 

I am thinking of a single JR 8611 on the rudder.

They are not available yet, but then neither is the plane, so I'm OK.

RE: Wild Hare Edge 540t set-up plans
 

I had not thought of that, but it's a great idea. I'm assembling a plane now, I'll try it if I can find one.

RE: Wild Hare Edge 540t set-up plans
 

leonard,

The 8611's are available. I got 9 of them last week from Horizon.

RE: Wild Hare Edge 540t set-up plans
 

Excellent.

It looks to me like it will be a perfect match for the Edge, especially rudder. Prob will use Hitec 5945's on ailerons/elevator.

RE: Wild Hare Edge 540t set-up plans
 

You said that you are going to use relia-switches. Are you going to use the regulated or un-regulated on the RX, and do you think 3amp is enough. I really like how the switches work. Great idea.

RE: Wild Hare Edge 540t set-up plans
 

Edge540TS:

I'm going to use the non-regulated. Here's a couple quotes from their web site:

Of course these ratings are for the NR Reliaswitch. The regulated ones have a constant current rating of 3 amps and a peak of 3.5 amps and a short circuit protection at 5.5 amp nominal. I'd have to say that yes, even the regulated switches is more than plenty in the amps department for this size of plane. If you where to double the digital servos to 12 (servos) and use them in a 40% plane, then I would go with their Super Regulated Switch which is capable of up to 9 amps.

Remember that any high amp load is very fast (peak) and short lived. With only 6 or 7 digital servos on a plane (like the WildHare Edge540T) you maybe using 4 of the 6 servos at once, maybe creating 2 amps at the most. And that only lasts for a fraction of a second, so my 2 amp guess maybe on the high side. 3 amps would be plenty on this plane and the NR's that I'm using at 4 amps continuous is over kill. (And 1 amp can kill a human being.)

Yes, the switches are a great idea. A bit more expensive, but they give peace of mind. Especially knowing when this plane is completely built it will be worth about 2 grand. A lot of money to lose because of a switch failure. Hope this helped in your decision to use these switches....certainly well worth it!

RE: Wild Hare Edge 540t set-up plans
 

Tom I noticed in your throttle and choke set up that you used metal and that the servos are very close to the engine and I would think that it would pick up interference and I was wondering if this is normal as I have always been told to keep radio gear at least 12 inches from the engine or is this something of the past

RE: Wild Hare Edge 540t set-up plans
 

Just wondering how the prototypes flew and if there would be room for a 3W 60 or is this really overkill?:D morepower

RE: Wild Hare Edge 540t set-up plans
 

I use metal pushrods but always insulate them from the engine by nylon clevises.

I try to obey the 12" rule, but have never had trouble with front mounted servos. Many people do it this way. Be sure to range check with engine running before you fly.

TF

RE: Wild Hare Edge 540t set-up plans
 

The prototypes fly/flew great, what else can I say. The Edge is nimble, great 3d for those who have the talent, it's stable and really easy to land, just like an Edge.

I think a 3w 60 would be just fine.

TF

RE: Wild Hare Edge 540t set-up plans
 

I cant wait for mine, already getting grumpy and its still a month out!! LOL :D Is this plane in a size category bigger than your standard smaller planes as far as setting the radio equipment up? Is it a good idea to run two receivers? Battery packs? If so, why? I'm new to larger aircraft and am greatly looking forwards to moving up. Thanks Tom for bridging the gap between under 80" 25% planes and the 30% and up planes that expensive quickly. This is a very reasonably priced airplane for the size, I've wanted something bigger for a while but seems once you get over 72" or so its up to a 31% for $800. These fill the gap perfectly, thanks in advance.

Brian

RE: Wild Hare Edge 540t set-up plans
 

Despite the great introductory promotion, don't think this is an $800 airplane ready to fly; it will run more like $1200-1500, with servos, reciever(ies) and battery(ies). My 2 cents. [8D]

RE: Wild Hare Edge 540t set-up plans
 

I wish... I'll have around $2000 in this ready to fly with an existing transmitter and how I intend to set it up. I have about $900 in a .40 sized Funtana with an existing tx :D And thats just a .40 size. Thanks though.

RE: Wild Hare Edge 540t set-up plans
 

Abraxxas:

Me too, at least $2K when I'm finished with mine. Heck the servos alone cost almost $800! It adds up fast.

But the comment I wanted to make to you was you don't need two receivers in this size plane. It's my opinion, but you'll find it's the opinion of most everyone else too. You don't want to get into using two receivers unless the plane is 40% or bigger. As for battery packs, it's always a good idea to run a redundant power system. Or, you may want to think of a isolator. What they do is separate the the servos from the receiver on the power side. You can then run a large pack (say 2400-3000mAh) for just the servos and use a 600mAh pack for the receiver. Since the servos are not depending on power from the receiver, a small pack like a 600 mAh pack would run that receiver all day long and then some. While your running a big (or redundant) pack(s) on the servos that are drawing the majority of the current from a bigger battery pack. The isolators also help to keep glitches or RFI out of the picture as the servos are now separate from the receiver.

P.S. I can't wait for this one either. I already have up to 33%, but the 84 inch to 90 inch range is what I like to stick to in size and this plane fits the bill. Tom is a wise business person for helping to fill that void in this size plane. There's not enough of them out there. And if this one is good, like I think it's going to be, I might pick up on one of Tom's Extra's next summer when they come in.

RE: Wild Hare Edge 540t set-up plans
 

I see now, thank you for the clarification. As far as two switches like everybody talks about, how is that hooked up? I think I could figure out how to get two packs wired in, how do you hook up two switches? I love this hobby, but have too many others to go spending $5K or $6K on an airplane yet which is why this one appeals to me so much. I am into guns, boats, motorcycles, computers and hot rod vehicles too :eek: so there is only enough money to thinly spread it around LOL. I appreciate the input and help, thanks again.

and, seeing you wear yours out RCpilot... KA9YJJ :D

RE: Wild Hare Edge 540t set-up plans
 

Dual receiver packs, which I highly recommend, are really simple. Each battery pack connects to a switch, each switch plugs into the receiver (any open slot will accept the power input). Turn on both switches and both packs power the receiver.

Eithr pack will fly the plane, so a battery or switch failure won't bring the plane down. This setup is vulnerable to a shorted battery pack, but that happens almost never, especially if you wrap the batteries well with foam so they are not sbuject to any sort of impact vibration.

RE: Wild Hare Edge 540t set-up plans
 

Abraxxas:

There you go, couldn't have put it better myself. Tom said it all. The setup is simple. The only thing I can think of other than what he said is, if your using all your channels on your receiver, just use a Y cable and put a servo on one side and the power (or extra battery) on the other side.

To make things easier, here's a picture of a I4C Isolator. There are many different brands of them. Some are optical & some are mechanical. The I4C in this picture is a mechanical unit. But you don't need a Isolator to run a redundant battery setup. It's just a way of seperating the Rx battery from the servo battery(s).

RE: Wild Hare Edge 540t set-up plans
 

Thanks for the tips guys, greatly appreciated!!

Brian

RE: Wild Hare Edge 540t set-up plans
 

Hey, I have a question about the I4C Isolator.

First, everybody should understand that its primary function is to provide more current to the servos in high load applications such as with a big 40% airplane with a dozen or more servos. The theory is that the little copper trace on the receiver that carries power is insufficient to drive a large number of high power servos.

BUt my question is this. If the battery for the servos fails, does the plane keep flying or does it come down in a heap? Is there provision for any redundancy? Will the plane fly on the receiver battery alone, at least enough to land it?

I went to their website, the Isolator has provision for 2 servo batteries plus a receiver battery, so it looks real good. I may try one on my large Extra.


TF

RE: Wild Hare Edge 540t set-up plans
 

Tom:

You are correct, the theory is that the copper trace on the Rx buss is not enough to sustain high current loads, therefore the use of a Isolator will eliminate that problem. And mostly used on 33% size planes and up because they do use 10 or more digital servos that can draw a lot of power. Since a lot of guys/gals are planning on using 5945's in this plane, if you have one that stalls, it could draw up wards of 2 amps (and more?) and fry everything and bring the plane down in a heap. Just cheap insurance (IMO).

2nd Question: I'm not affiliated with I4C or any other company. I used I4C as a example. Yes, I4C does leave you a spot for redundant packs. (IE: The picture in the last post I made shows a volt meter in the extra jack of the isolator, normally your 2nd or redundant pack gets plugged in here.) Now the way I4C does it is by adding a extra spot right on their Isolator for dual servo packs. In another case, the EMS/Jomar Isolator (called the Glitch Buster) also allows you redundant packs on the servos by using their Ultimate Battery Backer (or cheaper and simpler, just plug the redundant pack into their glitch buster on a unused channel or 'Y' it in if all 8 channels are in use). (BTW, the EMS/Jomar uses true optical isolation, where as the I4C uses mechanical.) Now on even another option, ElectroDynamics makes a isolator called the, Pow'R Bus Pro. This design is also a true optically isolated device. This one (like the I4C) has extra slots right on the device for adding a redundant battery system. And of course, with all these three devices you can run a redundant battery on the receiver itself. Yes, that's a lot of battery packs, but realize that with using a device like this you don't need a very big battery on the Rx side. You could run two very small 250 mAh size packs for redundancy into the Rx. The weight equal to or less than one 600mAh pack. Once the load of the servos is off the receiver, a receiver would run all day long on just one small 250mAh pack!
So you can have redundancy on the Rx & servos if wanted. (Best of both worlds.)

Hope this answered your question, Tom. Bottom line is, Yes, you can have your redundant system (on both sides!) if you want. I am in full agreement with you that it is a very wise practice to have two battery packs on the system in case of a failure in one of them. These Isolators will allow you to do this and also give you the protection you need if your running digital servos that draw a high amount of current (especially if one fails and stalls drawing a lot of current.) These Isolators, like anything else is up to the modeler if he/she wants it or not. It's not necessary and maybe something else in the system to go wrong. My opinion on them is that they are a nice extra to have because of the way it isolates the servos from the receiver, hence no glitches and for the separate power you can run to the servos and the receiver. Big packs on the servos where needed and a small pack on the receiver.

RE: Wild Hare Edge 540t set-up plans
 

I do this setup with 5 cell packs and even one shorted cell will give you power to fly and land the plane. My on-board monitor will tell me I have a problem
This has saved one of my planes that at present Diablo Kid is enjoying! :)
