Hi,

I'm currently running a Futaba HD switch and a Sanyo 1950FAUP which works fine but don't get many flights per charge. I'm running 3x 9255's, 9254, GY611/9256 and a 3001 on mixture.

I only want one just for the extra flights per charge, I don't need 6+volts to the servos.

Trouble with a reg is I don't have much room for one. I've got a Duralite 5.3reg to use but I'm limited on the battery as it needs the usual servo type connections and they don't really have the right dimension size pack which will fit well on the radio tray

Fromeco I like but it's big and needs mounting need the 611 amp.

I'm not putting an Align reg on a Eagle 3

Any suggestions or pics of how you have mounted one would be a help.

Thanks

Simon.

Simon,

Post a pic of your radio tray. My E3 is a VPUS, so I want to see what you have to work with in terms of space based on how your stuff is installed now.

Ignore the wiring and antenna's I will sort all that out, I'm in the middle of setting it up. I don't really want to move the GV-1 or GY611 amp.

Side note: I just leave the antenna like you have it there. Works just fine.

Your battery choices are either a 2S 2600 LiION which will easily give you a flight or two more than what you get now or a 2s2p pack of the same which will give you close to a dozen flights. The cells are no larger for the most part than what you have now. You can either position the reg heatsink up on top of the receiver or on the underside of the tray. I'm not sure if it'll go on the side of the radio/battery bundle or not. I CAN do that with my older Fromeco regs. My Sahara will be here in a a few weeks, so I'll be able to tell you exactly how it fits then.

If you choose a Li-ion or Li-po battery you'll end up on the tail heavey side. I had a duralite reg on my eagle. After it failed, I switched over to the Reactor from SG. I have a Flight power 2S2P 4350mah pack and it is still a little too tail heavy. I can get 5 flight with out any worries and a total of about 10 flights before charging. I am going to extend the tray to better accomodate the electronics and drop the size of the battery.

Hi Simon,

I use duralite 5.6v regulators and Duralite 2150mah Li ion 2 cell packs. I use double side to mount the regulator under the tray and the battery strap helps secure it. Light, simple and reliable.

Cheers
Brendan

Thanks for the replies.

My other E3 has a 2400 sub C nicad and that balances a little nose heavy with about 2/3, 3/4 of a tank with the 1950nimh its just about right.
I just leave the antenna like you have it there. Works just fine.
I was going to cross them over under the velcro strap so there 90deg apart and supported.

How many safe flights can you get before charging Brendan ?

I have FP 2s2p 3000 rx pack but it's too long a thin for good fit

Simon.

rhazbun,

does the SG reactor regulate down to 5.0 volts for the servos? I only want to use 5.0 volts, 6 is too high for some of the servos I'm using. I am considering moving over to Flight power 2S2P 4350mah since they're very good.

Hashimotos puts his radio gear WAY out on his Eagle SWM.

As I've already got two Duralite regs and their load tester I'm going to try the 4300 flat pack, seems to be best fit I'm looking for. Also it will save about 40g over the sub C nicad, hopefully it will balance out quite nice ? Cheaper for me to try this than splash out on a complete Fromeco set up.

Simon.

The Reactor will provide a regulated 6.0 or 6.8 volts to your 3 cyclic servos and 5.3 volts to the receiver and remaining servos, gyro, etc. A neat setup.

Hi synodontis
What servo's are you using,only if they are rated at 4.8v then they will run at reg 6v,a fully charged 4.8v nicad sits around 6v
Just a thought

old JR 8300 super servos. I don't think these like 6V one bit.

Will be using BLS252s when I move over to Futaba, they can take 6V.

I don't think fully charged NiCads ever see 6V, the charger will never allow it if I remember correctly. I use a 4000 mAh NiMh now and I get about 5.7V when charged and it never stays at this for very long.

I much prefer the regulated supply since you don't get voltage dropping flight after flight...

Have you been using a four cell nicad or a four cell nimh if so then you have prob been running them at 6v at times when fully charged
Sorry we posted both at the same time understand your point

I don't want them running at 6V. I want to get a 5V regulated supply. Unfortunately it seems that the SG reactor does not do this.

I've run both NiCads and NiMh but using NiMh now, will move over to Lipo with regulated supply next.

I have a Fromeco Relion 5200mAh battery + a Fromeco Sahara regulator. You can configure that regulator for a different range of output voltage. I have it set to about 5.7v then I run a step down for the tail servo which brings it down to about 5.3v. I have not tested the system yet, since the Sahara reg. started smoking and reset the system, a new one is on it's way from Fromeco. It's a fairly small regulator, the battery is a flat pack which is wider than a normal sub-c pack, but it will fit the Freya nicely.

synodontis,

Sorry for the late reply, but I was swamped with work. To re-iterate what has been said, the Reactor will not give you 5v for the cyclic servos. I had a duralite reg at 5.1v but it failed. I decided on the reactor after an extensive search. A fully charged Nicad or NIMH pack starts at 5.4 v. I had originally chosen my regulator and servos for this voltage. I am using airplane servos for the cyclics on this eagle. They are 9151's and a 9254 on the throttle. I am using the reg and the lipo so that I can fly all day with out charging. I have been using these for over 1 year on this reg with no problems.

A123 cells
What about installing a pair of A123 cells without a regulator? I'm not sure if you'd need a regulator on the gyro servo or not.

I'm considering this for my N9.

No,No..The other left!

Hi Simon,

I run Futaba 9255's on cyclic, 9252 on throttle and needle, govenor and Gy611 with BLS251 and I get 4 flights safely. Can squueze one more out but I usually have two machines with me whilst practicing.

Cheers
Brendan
