Your choice of using double 2,400mAh Fromeco Li-ons is a good one. You should be able to fly 6-12 minute flights a day for two days without recharging. You will save both weight and space, both of which are valuable in any aircraft.

I currently am using one 4,400 mAh 7.4 volt Li-on on my Extra, and can fly for several days on a charge. I do make it a point to check voltage between flights, and not just rely on guesswork. On my larger plane, I am using a double 4,400mAh Fromeco arrangement, very similar to what you have selected for your Edge, but of a slightly larger capacity due to increased digital servo counts, and longer wire runs.

The Super Reliaswitch is an excellent switch and regulator. It provides the ability to alter the voltage to the servos to a value that you want, and it provides one of the highest continuous amp ratings on the market. It also has a large heat sink, permitting the ability to shed heat at a high rate if needed. Fromeco's customer support is superb as well.

For your first gas/giant scale project you're making some pretty good choices. Keep up the good work!

ok that's good to know I'm on the right track.
Now how is the setup when you have 2 battery pack to power the receiver, 1 battery to the regular b/b connector in the receiver and the 2 battery pack to any unused channel in the RX?
Or how it should be done??

My Feedback: (47)

ooohh one more thing!!!

Does the WH edge comes with tail gear&wheel??? or it has to be purchased separately???
if so which one would be a good choice?

Josey Wales

YES!!

rctom

The planes come with a pretty good tailwheel assembly.

Dont mean to hi-jack your thread but since the topic of batteries came up here is a question..Ive read where you are supposed to take the packs out of the plane while charging li-ion ..If you needed to use a pack for nose weight that would mean the cowl would have to be taken on/off for charging correct? Or is it ok to leave them in the plane..

charrua

My Feedback: (47)

No problem Redrum you are welcome here!!!!
I have no idea about that but I'm not thinking in installing the batteries inside the cowl so I don't think that would be a problem for charging the batteries.
Why would you have to take the batteries out of the plane to charge??? is that true???

Josey Wales

My Feedback: (61)

Well Ive read that they can get pretty hot when charging so you want to keep them well ventilated..Now there are 2 types Li-ion and Li-poly..maybe the warning was for Li-poly...I thought that I read on Fromeco's site that they suggest removing them for charging..

Since Im goig to be using a DA-50 most of the guys need some weight up front and a good place to add the weight would be using a battery pack on the engine box..

Icebird

I used a DA 50 and didn't need ANY weight up front, so my rx batteries are attached to the wing tube. Lithium batteries do NOT get hot during normal charging. They will get extremely hot and burst into flames if they are charged improperly however. My lithium packs don't even get slightly warm either during use or charge. I leave them in the plane, but then I use a proper lithium charger as well. If you don't use the correct charger, you're going to have problems for sure. This is the reason they tell you to take the batteries out to charge them, because some people have made charging mistakes. A certain moderator on this list even blew up a pack, but don't worry Tom, I won't mention your name! :-)

has any one ever used a BME Props? Are they good?
I may order some staff from chief and they don't have the menz props.I saw they have a very good price on the slimline pitts muffler for the DA-50
I wish I could order everything just from 1 place!!!

charrua

My Feedback: (47)

Ok I just made my first order 5 mins. ago,,,, I ordered the batteries from Fromeco.
2 7.4v 2400mah li-ion and 2 Super Regulated Reliaswitches so I think I'm set as far as power I already have a 6v 2000mah ni-mh batt. I could use for ign. or I also have a 4.8 1500mah ni-cad I could use not sure which one yet.

So now I only need everything else.... like plane,servos,hardware kit,engine,muffler,spinner,etc.
not much! maybe just another $1700 and 3 o 4 more phone calls!!![img][/img]

But I know 1 thing..... I'll get there!!!!!

yes I know, I'll be getting pretty much everything from him. I whish he had props too!!

Use the 1500 4.8 in the ignition. THe DA ignition should not be used with 6V packs as the voltage is too high and can cause problems. THe 1500 will be plenty of juice for the engine so no worries there.

Menz props are available through ohio model products, get a 22 x 10 and get ready to hang on to the plane tight!

I have to disagree with Shogun, Per the DA-50 instructions 4.8 and 6 volt packs are acceptable, Packs over 6 volt rated capacity must use a regulator.

Josey Wales

My Feedback: (61)

I also thought the Fromeco regulators can go from 4.8-6v

Shogun

My Feedback: (2)

OK so maybe I wasn't clear about this....the DA ignition should NOT be used with a power source that exceeds 5.5 volts, how you acheive that is up to you.

Shogun

My Feedback: (2)

Now that I think about it after reading back through the posts you really don't need to be concerned about the ignition battery anyway, let me explain.

The reliaswitches are a fail safe switch and as such will fail in the on position. Standard mechanical contact switches can get dirty or fail mechanically and disconnect the power from the rec and cause the plane to crash, trashing all your hard work and cash.

Considering that your buying 2 of the packs and switches, if it were me I would use one of the ignition and the other for the radio. If I was using regular mechanical switches I would definitely go with 2 packs through two switches. The whole reason for the redundancy is to avoid a crash due to a switch failure. The reliaswitches have no moving parts and therefore are much less likely to fail and that would give me the confidence to fly using only one of these.

In fact this is just the setup I plan to go with for next summer, it also saves you the wight of the 2nd battery and switch.

well thanks for the advise shogun...but I think I want to get this thing right or as best as I can so I'll still go with this 2 batt. packs with the 2 reliaswitches for the receiver and the 4.8v 1500mah for ignition.
I was gonna go with smoke in this plane but I think I'm gonna change my mind about it and not use smoke now.

Talking about ignition...does the DA-50 comes with the ignition thing or it needs to be purchased separately?

mstroh3961

My Feedback: (4)

DA supply's the ignition with the engine. You provide the battery and switch.

ok that's good 1 less thing to buy!!!!

I'm not positive, but I believe the Fromeco regulators are adjustable from 5.03 volts and up. At least that's been my experience.

4.8-5.03, big difference, eh? sheesh.

#########
Okay, I went out and re-read the instructions. The Fromeco "Super Regulated Reliaswitch" is stated to regulate from 5.30 to 6.30 volts. I know I have my flight batteries regulated to 6.03 volts using this regulator. It also contains an on-off switch for the batteries. They will draw some current when in the off position due to their design, but you're only talking about 3 or 4 mA. It should take several months or longer to draw down a large capacity battery to a level requiring a re-charge.

Since I install batteries and switches in locations where they can be easily accessed, to plug and un-plug is no big deal. During the flying season, it becomes even less of a deal. You have to remove the canopy and hatch to remove the wing anyway, right? If you're flying every weekend or two, there is no need to bother with the plugs at all.

Fromeco's "The Regulator" is not a switch, but a regulator only. There is nothing noted about any of the Fromeco regulators failing in the "on" or "off" positions. You should contact Kurt direct at Fromeco for more information on any possible "failsafes".
