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.

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..)

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

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.

Edge540TS:
I'm going to use the non-regulated. Here's a couple quotes from their web site:
quote:
High ratings: The NR is rated for up to 18 volts, and can carry up to 4.5 amps, continuously (this level of sustained current can turn the standard 3-pin plastic power connectors into little plastic puddles).
quote:
Ratings:
Input voltage: 18V
Current: 4.5A continuous >12A 10% duty cycle 100ms pulse (extrapolated) Fromeco advises against designing an electrical system that will utilize the full continuous or transient ratings - this is a lot of current for typical wiring harness components!
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!

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

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.
