Scott Douglas 1 Posted August 11, 2014 Share Posted August 11, 2014 Guys After a few years away from jet flying due to family/health issues I'm ready to return. I have a JL 1/6th F16 on order and a Wren 160K Pro for it. I fly Futaba through a 14SG but I prefer JR servos so it's a mix of 8411/8511/8911 servos on the major surfaces. Before, on my Boomerang, it was simple setup but with those servos/lights/afterburner ring etc I want to be as safe as possible but I'm not really up to spec on the latest powerboxes. What would you recommend re batteries and a powerbox if I went down that route? Quote Link to comment Share on other sites More sharing options...
Pete B Posted August 11, 2014 Share Posted August 11, 2014 Apologies, Lee - it seems two mods each deleted one of your double post at the same time... Fortunately, we've found the text so here is Lee Smalley's contribution: well use of a powerbox depends on servos, number and type, if you have multiple servos and each one is Hv and high torque then this amount of current can cause damage to some RX, most powerboxes divert this current away from your RX and so the only thing your rx does is receive the transmitted signal and distribute the signals to the appropriate channels whilst at the same time providing battery regulation and redundency (it depends what version you buy obviously) on my boomer i have a digi switch but on my next two jets i will be investing in a powerbox evolution it will take care of most of the primary flight controls have a look: **LINK** Pete Edited By Pete B - Moderator on 11/08/2014 14:40:27 Quote Link to comment Share on other sites More sharing options...
Scott Douglas 1 Posted August 12, 2014 Author Share Posted August 12, 2014 Cheers Lee, I think I'll go with a powerbox cockpit Quote Link to comment Share on other sites More sharing options...
Scott Douglas 1 Posted August 12, 2014 Author Share Posted August 12, 2014 Although now I see on another forum that this thing has an issue with Futaba users that hasn't been resolved yet. Gawd I miss just plugging in a 4.8v NiCad and going flying!! Quote Link to comment Share on other sites More sharing options...
Lee Smalley Posted August 12, 2014 Share Posted August 12, 2014 email powerbox find out what they say, forums are not always accurate, be careful what the powerbox regulates at some JR servos really do not like 6v Quote Link to comment Share on other sites More sharing options...
Scott Douglas 1 Posted August 14, 2014 Author Share Posted August 14, 2014 Thanks Lee All the servos I want to use (8411, 8511 & 8911) are only really happy on 4.8v. The powerboxes I was looking at all start at 5.9v Quote Link to comment Share on other sites More sharing options...
simon burch Posted August 14, 2014 Share Posted August 14, 2014 Lee, i think most people run those servos on 6v regulated with no problems. Seen a lot of jets with those Hugh end digital JR servos on powerbox switches. I use the powerbox gemini 2 which is rated at 10 amps and a bit overkill for my jets. Cheers, Simon Quote Link to comment Share on other sites More sharing options...
Lee Smalley Posted August 14, 2014 Share Posted August 14, 2014 despite being a jr man i only really use Hitec servos, and so don't have the problem, but i would not be prepared to put JR servos (at Jr prices) on 5.9v because someone else knows someone who does and does not have a problem, i don't fancy blowing up a 50 quid servo and not being able to take it back !!

Scott Douglas 1 Posted August 14, 2014 Author Share Posted August 14, 2014 Only 50 quid? Quote Link to comment Share on other sites More sharing options...
Scott Douglas 1 Posted August 19, 2014 Author Share Posted August 19, 2014 After some more deliberation and a few phone calls (where I was recommended to use Futaba servos!), I think I'll go with this lot... Elevators - 2 x Futaba BLS177SV Brushless HV S-Bus2 Servo 0.11s/37.0Kg Ailerons - 2 x Futaba BLS157HV Servo - High Voltage Brushless 0.14s/31.0kg Rudder - JR DS8411HV 17.2Kg/0.15S High Voltage Servo Seeing as they can all happily take 6v I'll feed them through a Powerbox cockpit SRS with a Cortex gyro. What do you think? Quote Link to comment Share on other sites More sharing options...
steve 1 Posted August 19, 2014 Share Posted August 19, 2014 Hi Scott, i have been using jr 8411, 8511 & 8915 through a powerbox cockpit srs regulated at 5.9v for the last two years without any problems in my hawk (and other planes) but can't say about gyro's as i dont use them. Couple of hawk pics in me album. Steve Quote Link to comment Share on other sites More sharing options...
Lee Smalley Posted August 19, 2014 Share Posted August 19, 2014 Gyro!! Are you a girl or sommat why do you just get someone else to fly if for you all the time instead �� Quote Link to comment Share on other sites More sharing options...
Scott Douglas 1 Posted August 19, 2014 Author Share Posted August 19, 2014 Posted by Lee Smalley on 19/08/2014 09:19:20: Gyro!! Are you a girl or sommat why do you just get someone else to fly if for you all the time instead �� Am I a girl? Well my wife doesn't think so (and she likes men!) Nah, I was always going to fit one. I've had a couple of Yellow F16's in the past and still have a BVM D/F one in my hanger. None of them liked landing in a crosswind with that huge fin and at my club, the runways seem to be more often crosswind these days than not, plus they're only 30ft wide with little run-off. Everything I've seen & read says the Cortex makes a huge difference so I figured "what the hell".. besides, what difference does another few quid make when you've spent this much Quote Link to comment Share on other sites More sharing options...

Scott Douglas 1 Posted February 6, 2015 Author Share Posted February 6, 2015 Guess what.. I still don't have the damned model.. takes apparently 4 months to decide they cant do a paint scheme (even though Uncle Bobs customers get theirs in 3 weeks ). Supposed to ship now on 08th Feb.. We'll see... Still, the rest of the gear is here.. 2x Futaba 7003 Rx's through a Powerbox Cockpit SRS, Powerbox IGyro SRS with JR8911's for the elevators, 8511's for the ailerons and 8411's for the rudder/steering... I know I thought Futaba servos but a friend had an issue with a couple recently in a heli and it put me off completely. Quote Link to comment Share on other sites More sharing options...
