Best flying planes on the market... 1 - Extremeflight Extra 88" 2 - Extremeflight YAk 88" 3 - BME extra 330L And if i cant have the BME......i'll have a magnum R. I have all of them anyway!! lol! Can i also shout out for the DL50 petrol engine!

I wouldnt do that.........the expert is a good system and a safe move into these things...take no notice Doug!!

lol! next time buy your batteries from gliders.....they put the connectors on for you. Timbo...thats correct, i believe these connectors are rated at 40A..which is nice.... Once you know where to get the bits...it is easy! honest. If it makes you feel any better, the Lipo version is alot sompler to set up, just plug the batteries straight into the powerbox. If you buy Duralite or Fromeco Lipo's they're pretty reasonable price wise too...i have them in my 102" Yak with a powerbox evo.

Thats right..you need to solder the positive and negative to 3 pins on each plug.

Why do i have 2 posts the same...lol? I'm not going mad am I? 2400 is what i use, but as 4.8v, lasts all weekend on my DA / DL's Good luck with the balancing!!!

Thats a BIG ignition battery Doug!! What MAH is that?

Hi Doug, Your using a regulator then? or is it a 3w motor? Can't you tie wrap the ignition battery to the motorbox? or move the receiver batts alongside the tank somehow? Cheers D

Thats a BIG ignition battery Doug!! What MAH is that?

Hi Doug, Looking good! Dont forget you dont need to use the power input on the receiver....just checking.... If you do need to move the batteries about and you need an extension lead....let me know...you can get them from EMCOTEC of germany....or northern hobbies in the UK CHeers  D

forgot to add....I use this system with 5 x 24Kg hitecs, and it performs faultlessly.

Hi Doug, I have 3 powerboxes and they are excellent peices of Kit. I mostly use the expert for NiMH's as i dont quite trust Lipo's yet, besides which the size of models the Powerbox usually goes into, a few Oz here and there makes no difference to me.  Anyway....I get my Nimh's from Gliders in Nottingham, usually 3000MAH http://www.gliders.uk.com/ They will put the connectors on for you..if you need the green Multiplex (MPX) 6 pin connectors, as shown on the far left in the picture at the top of this page linked below. The powerbox does come with some. http://www.puffinmodels.com/batteries_accessories.htm  Do you have the powerswitches with the charge socket in them? If not you will need to make sure your batteries have a 'fly' charge lead on them as you cant charge through the powerbox. hope that makes sense? CHeers W

Servo connections are standard....you need to remove the small lugs on the edge of the futaba leads as per normal, hitec and JR servo's plug right in. What you see in this pic is on the right of the powerbox are leads that go into the receiver, then the servo outputs for the main control surface servo's come out of the left (Top of powerbox). The two red leads go to Two external LED's which warn you if you have a problem with either power side. The two green plugs are from the power switches, of which you have Two. So you have one powerbox expert, 2 switches and 2 batteries....complete redundancy.

forgot to add....there are no issue mixing JR / hitec / or futaba servos with a powerbox.

Hi Peter, You can get the Powerbox's from Als or Motor and rotors. As for the batteries, you can get the multiplex connectors and solder them on your battery of choice, most hobby shops carry just the connectors. I get my batteries from gliders in Nottingham, they will put the connectors on for you. The powerbox power switches (they are known as powerswitch set) have a built in charge socket , you can put 2A max through the switch for charging purposes, but the switches are rated at 20A throughput to the powerbox!!  I really like this system....super bulletproof.. The powerbox designed esp for NIMH or nicads is the 'expert', the evolution is for Lipo's or NIMH and has a built in regulator, the switch with the evolution does not have a charge point, so if you go for that, you will need an extra set of 'fly' leads on the battery to charge through. But if you will only ever use NIMH or Nicads, stick with the expert. It also handles 4 cell batteries as well as 5 cell, you just change a 'jumper' on the side of the main unit, depending on what your cell count is...its real simple!! http://www.alshobbies.com/shop/cat.php?id=189&Desc=&PHPSESSID=f66ed16205a4b0410264358cf693d652 As for servo's I used futaba for many years, but i find hitec better for larger models, i use the 5985's (13Kg) or the 5955 (24Kg). Generally the 5985's are for all surfaces except rudder, where i use a 5955, all running at 6v off 2x NimH's through a powerbox. You could use one battery with no redundancy if you like. Unless your doing hard 3d on a large petrol model, the 5985's are great! One word of warning though, the 5955's are very difficult to get hold of...i get all of mine through an american website, which offers fantastic service, its called troybuiltmodels, they are cheap, always have stock..but beaware you may have to pay import tax...which still makes it cheaper than buying over here!! These guys are doing 5955's at 90$! which is way below the $140 you should pay over here.... i now use these on all my surfaces because at this price you can afford to. http://www.troybuiltmodels.com/ServosHitec.htm#HS5955 Sods law...looks like they have put there prices up a little...but still worth a look!  Any more questions, dont hesitate to ask. Happy landings...  Dave

got it....see my photos's

How do you upload pics?

Hi Peter, The 4100mah is plenty!! I have a 1 x 3700mah on a CAP-X running 6 x 5945 Hitecs, never had any problems. Good choice on Sub C's too.  D PS: i just picked up on the battery backer issue. I have always used powerboxes, specifically the expert, which is designed for 2 x Nimh or Nicad. This thing gives you a battery backer, clean supply to the receiver, drives large servo's over long leads, provides a battery status, gives you the lowest voltage seen during a flight..etc etc... You can get them for about £105 + switches, which are about £45. Just bear in mind that you will need multiplex connectors on your batteries...see attached pic of one of mine in my ef yak.
