Many people are having problems operating Hitec 5955 servos on the new FASST 6014 Rx by Futaba, since the 6014 Rx is the first Rx that has a signal voltage of 2.6V (up to date all were over 3V).

I just went off the phone with Emmerich, the owner of PB systems, consulting him about an electrical system for my Eurosport and Cermark F-16 and he gave me some very useful information.

1. To be able to use a single device (servo, electronic valve, ECU etc) on the 6014 Rx (if it doesnt work) one can simply use a PB signal amplifier and it will increase the signal voltage which will make it work:

2. ALL current PB systems have signal amplifiers and will work with Futaba 6014 and 5955 servos etc. some older model PB's will not work, but they are upgradeable at no charge by sending them to PB systems - thats great service !!

So, for those of you (like me) that like the 5955 or bought a bunch to use on your jets - this is in fact a pretty good solution !!
it can also be used for rhose of you who are having trouble operating electronic valves and such on the new 6014 Rx.

Hope you find this information useful.

Status: online 		You need to use caution when using an amplifier. Some brands out on the market do not accept a low voltage signal. Some chips split the supply voltage into three segments. In order for the amplified chip to see a "high" or "low" signal it must be higher than the bottom 1/3rd of the supply voltage window. For example, if you had a 5 cell pack that was fully charged, you could get up to 7.2+ volts. Divide that by three, and you get 2.4volts. Now the signal must be above 2.4 volts for the chip to see a "high" signal before dropping off to the low. And this all depends of the style of chip in the amp. Too close for my comfort factor.

Time will tell, what systems work with this new 6014. I personally think Futaba needs to make their system more compatable with the industry. They cant fall back on the "Futaba can not guarantee other brands with their system" mentality.

Apple computer is a good example. It is different enough to make it a hard sell except to the hard core apple users while PC dominates the market.

I do believe the Futaba FASST system is the best out there, if only they could be a little more accomodating in this signal voltage issue.

Status: offline 		Having a brief look at the diagram in the powerbox instructions, it looks to me like the amplifiers are supplied with regulated 6V plus or minus 0.1V. Therefore the highest voltage the amplifiers can get is 6.1V.

One third of this is 2.03V which is a bit further away than the 2.4 you mention.

Also, which type of chip is in the Powerbox Amp? Is it one that could cause concern?

I am not saying that I am correct but I am sure Powerbox would have thought of this before offering it as a solution.

Status: offline 		Emcotec will work also. This was taken off there website.
"The new 2.4GHz Futaba receivers are powered internally with a lower supply voltage of approx. 2.7 volts. Therefore the level of the servo signals is also considerably lower than in "normal" receivers. There are discussions floating in the internet concerning incompatibilities with battery switches and current-distributors. EMCOTEC DPSI RV Systems (as well as DPSI TWIN systems) are not concerned and can be utilized with no reservations! Due to by default conducted FMEA at EMCOTEC, these kind of incompatibilities are eliminated during development in the first place. Only the first generation DPSI 2001 from the year 2001 (recognized by serial number stickers containing "Sebastiano Silvestri Edition" can not be used with this Futaba receiver. Of course, we modify your old DPSI 2001 at factory costs on customers demand. "

FUTABA will have you $pending your cash really Fa$$T now!

powerboxes amplifiers the list goes on??? more cost = more weight

I will stick to my PCM Rx on 72 mhz.

At least you do have a way around the hightech roadblocks.

Does it work with the Futaba 6014? Someone tried the JR amplified lead and it didn't work.

It was me that used the JR Y with the amp. Mine did not work. It appears older amp chips do not work whereas the newer stuff does. You will need to see for youreslf which ones work or do not.
