100cc setup

[Deveus]

I'm new to giant scale models and I would like to know how to setup 100cc Pilot RC extra 260. I have Spektrum DX7. My friend told me that I don't need powerbox, but how can I then join 2 servos on each elevator? And which batteries to use? I will put Power HD servos on plane, and they are not programmable, so does that make some difference? Thx

Deveus, you will have 2 servos in each aileron, 2 sevos in rudder and 2 in elevator. The best choice is to chance your radio to at least 8 channel. Channel 1 - 7 ail, 2 - 8 elev, 3 acel., 4 rud, 5 ignition. I have an Emcotec to divide the tension and use LIPO bateries. The smart-fly system is good too.

depends on how you want to mix channels. either a servo matcher like a jr matchbox($70) or a smartfly equalizer ($40). if you do that i would run a123 batts to the spektrum or jr 9 ch power safe rx. it has more satellites to pickup the tx signal and the high power inputs and fail safe switch. this setup would take a servo matcher per wing, using flaperon mode, mixing the 2 elev, and the 2 rudder in the radio on mix 5/6. this leaves one channel for throttle servo.

or you can do it by mixing servo's and handling power distribution with something like the smartfly EQ10 ($250)(A123's) or EQ6 ($255)(lipo/A123's). the failsafe swtich for these cost another $20. the eq6 offers for another version for $275 which adds an ignition kill switch.

look at this for help with radio mixing on the dx7

how did we power all of those servos in years past without the Power Boxes, EQ10, etc.? A second receiver would work, but you need another set of batteries, regulators and switches. Lots of $$. Personally, in your case (100cc airplane, first big gasser, probably won't be flown too hard for awhile...) you would be fine with a pair of SmartFly equalizers for the ailerons (total of 2 channels used and simple rigging/hook-up) use the ELEV and an AUX channel for both elevator servos (2 more channels used), use the RUD and another AUX channel for the rudder (2 more channels...we're at 6 of the 7 available) and your throttle servo (ta da...Ole #7!), but wait! What about the ignition kill? That would be an 8th and unavailable port/channel. Well, you can set up a program mix so that when the throttle is at low/low trim, the ignition is OFF (or something like that), OR you can use another SmartFly equalizer on the rudder servos and only use one additional channel. The cost of the equalizers (3) would be less than $150, probably the most economical way to get in the air and you would have a channel dedicated to the ignition kill (which I highly recommend putting on an auxillary channel that utilizes a rotary knob, or the snap roll button switch, so that it takes a conscious effort to activate it, unlike a conventional switch which can be flipped by accident in flight...trust me on this one).

good luck and happy flying

Money isn't problem, and I don't want to change the setup later, so I want the best setup that can go in the plane. I was thinking about Spektrum AR9100, but it doesn't have ignition kill switch.

[nate428]

i would still consider the ar9100 just for the 4 satellites, i just lost my 50cc from radio loss last week.
smart fly ($60) and 42% products($35) make stand alone ignition kill switches, the smart fly seems a bit better imo.
if using a kill switch we will need to get your servo's down to 5 channels.
the jr matchbox does program 4 servo's but it only has a single power input, i would only run 4 analog on that.
the smartfly equalizer 3D has 4 servo's and two power inputs, this is the way for digital. if using this device with the ar9100 you can supply the 2 power inputs to the smartfly from the spare #8 & #9 channels. using two male to male extentions and removing the signal wire should work. so, 1 ch for ale, 2 for elev, 2 for rudder = 5.
or if you want to, you could purchase a single high power servo for the rudder and save a channel by not mixing 2 in the radio.the jr 8711 or hitec 7950TG (lipo compatible). this could bring you down to 4 channels and allow another free channel for smoke!?
you can still go with a power system like the eq10/eq6. its possible to use a 7ch rx like the ar7000, especially if you already have one, it just wont have as many remote satellites as the 9ch. just look through the features and see if you want to pay for em. look through the manuals and mfg's websites on all these products. also search and read through forums here, do your homework on these and make sure you know its what you want.

the power setup for all this would be nice on lipo, but i dont believe the servo matchers run that high of voltage. you may need to email smartfly or ask that under the smartfly support section here. i use a123's and like them, my friend just got some of the 42% life/a123's and they are working fine. i personally don't like regulators after reading too many plane loss stories from reg failures.

mixing the radio can be tricky, so don't be afraid to ask for help if you get stuck. most important step might be to make sure you disable/inh flaps/aux2 and their trims. both of those are under the same screen. this will disable the switches and stop them from messing up the mix. supposedly the gear channel mixed with elv is the best, you have to set the trav adj to zero allow the gear channel to be mixed properly.

[Deveus]

I have ar7000, and I have on yak 54 with those mixes for 2 ail and 2 elev, so that's not problem. I think I'll go with power system eq6. Thx for help

I really think you should read some posts about those servos on a 35% plane. I would spend more for better servos if I were you.

[sherman89]

I agree with Karl540, if money has no bottom go for a quality servo. I am flying a 35% Yak/3W-110 using the Spectrum DX-7SE with the new 7600 Rx using 5955's every where except a 8711 on the rudder. The servos run off a Smart-fly Sport and use match boxes at the ailerons and elevators. I use a IBE to eliminate the ignition battery and feed all power requirements via 2-Smart-fly dean to dean switches from a pair of A123-2300mah paks. I use the DX-7SE as I fly heli's as well.

[cliff600]

I think IMACmike has the best plan. I have a 35%er on a AR7000, I use matchboxes on the ailerons and elevator halves. I even have smoke on it, I do not have a kill switch though. I have been flying like that for 4 years now with no problems.

[crazyjoe]

I cant figure out why guys are willing to use three matchboxes but will sit there and say you dont need a power box keep it simple. You can get a smartfly power expander pro for $150.00 . Its much simpler and offers much more features than three equalizers. Ive been using them for years and have yet to have or even here about anyone having a problem with one. You use 2 batt with deans in and one failsafe switch that is only $19.00.

I agree but every time I recommend a better servo I get a bunch of guys jumping down my throat. Their argument is all servos have problems. I say thats true but there are a lot of posts with problems with HDs in comparison to the other guys. And how many HDs are in use compared to JR and Hitec. I prefer a servo I can program.

[Deveus]

I was talking with guys in my club and they recomended the hyperion servos, because they are programmable and have spare parts, so I will buy these.

[Karl540]

Never had a problem with Hitec. And by the way why dont you just get a 9 or 10 channel radio and forget all that matchbox, servo reverser crap. If you get programable servos then that solves half your problems. God luck

[choopi]

I'm thinking of getting that for Sback 342 100cc on my DX7: Hitec HS 7950TG(1 for the rudder) 4x7955 aileron, 2x7955 elevator. Smart-Fly PowerSystem and Equalizer EQ6 Pluswith the kill switch, also the Smart-Fly Failsafe Switch with the flag how many of those I need 2 or one? As for bat pack 2 A123 pack 2s and maybe an other one for the engine ignition or use the pack for all. What do you think make sense?
