HI Peter, when I first got the 220, was disappointed at the lack of instructions, but that changed quickly when it started right out of the box, in what seemed like 3 seconds. Fastest turbine start up I have ever seen, and the sound makes you smille, ear to ear, outstanding turbine.

Well I am lost for words, tonight I powered up the Futura and all works, as it did yesturday morning. The only difference is the turbine was running when the PB started to fail.

hey rc pete ,,good to know you found this problem before it was in the air ,,,,,,i lost my ultra lightning last season ,,powerbox failed in front of me at one foot off ground while landing ,,it also worked flawless and never gave me a hint of problem ,,,but as my plane rolled over i seen both elevators in different directions moving up and down and if that happened in the air i would never knew what happened ,,my best clue might be when the flaps were down burnt something from draw through box ,,this is why im saying this my receiver was burnt up ,(never had this happen ) batts where completely ruined ,so i used new 7.4 batts thinking batts went out (the ruined duralite plus batts )but when i plugged the flaps in from box to brand new receiver the needles to flaps burnt completly off ,the receiver ,(try to explain that to horizon two receivers) but they took care of me ,,guys im glad the box works for you and i am with you but ive lost a fortune because of what im sure was due to the power box system ,good luck whoever uses it i hope you never have a problem as bad as what happened to me or other guys but this was on a plane that had only 50 flights ,,im learning on how to use my powersafe and good life batts now and i tell everyone who asks me ,,and im sure that one potential problem is missing now

Get it checked out by PowerBox nonetheless. They have very good service.

100% agree

I bought Jets that comes with power box and rip them out...Batt..Switch..Receivers ..that's all I need :cool: Just my opinion.

Pete,

Does this engine use a single channel ? or is there an aux ? I had an issue once with a Powerbox (non srs ) and a JetCat ECU. In my case I was using the throttle and aux channels to the ECU both going through the power box. For whatever reason, when powered on, this created a loop/short somewhere and cables would start to fry. I ended up connecting these 2 channels directly to my receiver and never had the problem again. I spoke to Bob Wilcox about this and he saw no way there would be a short/loop anywhere based on the set up, but it was an anomaly that almost caused a whole plane to go up on fire if i had not been looking at the cables . Powerbox and ECU both checked out fine. .. go figure.

Pete,

Do you know what version your firmware is? I'm also using an 18MZ with 2 7008 receivers and had intermittent glitches on the elevator when the PB Royal SRS had V1.0 firmware. I've since updated to V4.0 but have not had the chance to power the system up since the update.

HI, how do you know which firmware your Power Box has.

rcpete,
During the power up of the PowerBox Royal, There will be a version of software in the lower right corner of the display screen. The newest version is V.4.0

HI, when I power up, I do not see the version.
Rcpete

HI all, I think I might have found the reason the Power box opened two matched channels when the turbine was running, bad install.
I can not think of any other reason the PB failed, but from static electricity from a bad install, the pump and fuel lines too close to the receiver and Power box, see pic and see if you guys agree.
First runs in Florida where hot and humid, in Canada last week, cold and dry.

I think the only problem it's all the wires in order and tide with zip tide the wires don't like to be tide all together in straight line , for complex connection the all should be twisted or loose ,,rats neast ,, than no statick charge and dibble signal confusion .one more think no more dean connection for me the creating static arc on the folate use round blue or multiplex .

A stalled servo or two in a jet, with a Power Box will kill the matched channel it is pluged into, you have to send the PB, back to Germany. I landed a jet with the flaps down gear up , killed the channel and the servo.
A fire in the tail of a jet that melts the Jr 8611 elevator servo wires and is a dead short will kill the whole Power box, it will fry the printed cruits in the Power Box, been their.
Power Boxs are great, too bad they are built, idiot proof.

These will do a better job without sending them back to germany, without frying anything and without causing any fire.

I agree with proper battery Redundancy, other than that if your receiver or servo fails a powerbox is not going to help you out. too many connections hard to trace, firmware updates etc.

I had a lengthy discussion with one of the radio reps about powerboxes, if JR or Futaba thought they were necessary they would build them and get a bit of the market. (they do build receivers with dual battery inputs so they agree on that)

There are some very large complicated builds that might make sense for the multiple channel outputs but for most Jets/planes I feel they not required

But it is still a hobby we do what we want to make ourselves happy and comfortable

my 2cents ;)


Regardless, Pete glad you didn't go up, that is one beautiful jet, look forward to seeing it in July
