RE: Lost JetCAT p80 in Germany on sep 14 in bad Neuenahr.
Good luck finding your engine, wish I could help. I owned P80 serial# 1017. It was a strong little motor for it's day. I hundreds of hours and over a 1000 flights on it before it was so worn out that it was just cheaper to replace it. I hope you find yours.

RE: composite fuel tanks
I've used West Systems epoxy on all the tanks that I've built over the years. Never had a problem with the fuel affecting the epoxy. No fuel line will last forever, but I think trygon will probably last as long or longer than any other type of flexible fuel line inside the tanks.

RE: Fuel Shutoff Valve??
[quote]ORIGINAL: lov2flyrc From experience.... BEFORE the pump! If an ECU malfunctions, the pump can still be running providing full pressure. Closing the valve abruptly can burst a line and make matters worse. If located before the pump, fuel flow stops IMMEDIATELY. These are gear driven pumps; if there is no fuel entering the inlet, no fuel can exit the pump! Thinking fuel will still be delivered for ''seconds'' is incorrect. If there is no fuel being fed into the gears, the fuel has no way of being pushed down stream. We have personally witnessed a runaway ECU with a fuel valve placed after the pump. Fuel was shut off, line burst and filled the interior of the plane with fuel as the owner scrambled to unhook the ECU pack..... Personally, I see no logical reason to place the emergency shutoff valve AFTER a pump? It is no more prone to leaks than any other fitting in the system and in an emergency situation (the main reason the valve is required); far safer suffocating fuel from entering than blocking full pressure of the pump! JMHO [/quote] I agree completely! [sm=thumbs_up.gif]

RE: Futaba S-Bus system
Thousands of years ago cavemen were terrified of fire until they learned how to control it. A hundred years ago there were many people who were terrified of having dangerous electricity installed in their homes simply because they didn't understand it. Seventy five years ago most people believed it was impossible to fly faster than the speed of sound. Until people learn the limitations, and how to properly use new technologies there will always be those who refuse to accept it. I think Sbus is the way of the future for Rc model aircraft control. It may not be perfect but I think it's advantages far outweigh it's limitations at this point, and the possibilities for future innovations are almost endless. I am not scared of Sbus!

RE: Futaba S-Bus system
Over the last 10 years I have over 1300 flights on my Bobcat using 72mhz, single receiver, and a single 4.8v battery pack. Absolutely no redundancy and absolutely no broken servo wires or other serious issues. I am not saying that it won't ever happen, but if your airplane is built (or assembled) properly and you maintain it properly the chances of a catastrophic failure are relatively slim. The Sbus system allows for installing extra battery packs to copy with high amperage draw servos, it easily allows you to use two receivers, and it is absolutely possible to standard servos either plugged into the PWM channel ports, or into the Sbus system using a SBD-1 decoder. Sbus servos do allow a lot more programming options than a standard servo with a decoder, but standard servos work just fine. While I have no experience with any of the Robbe equipment it appears that it makes the system even better, and provides true battery redundancy too. I will be seriously considering the Robbe stuff when I start fitting out the plane I am working on now.

RE: Futaba S-Bus system
[quote]ORIGINAL: Xairflyer Now of course futaba tell you you can remotely power the servos by plugging a battery into the hub, [b]yes great idea to put a battery in the tail[/b], really helps with CG does that! [/quote] Why do so many people think the battery has to mounted right next to the hub? Why do so many people think that one battery can only be plugged into one hub? The battery leads can be as long as you like. The battery(s) can be placed wherever they need to be for balance, then you can run heavy gauge wire back to the hub(s). The heavy gauge battery lead can then be tapped off of in several places to attach to multiple hubs. (think power bus) I'm thinking I might used one battery attached directly to the receiver to power the receiver and any PWM servos attached to it, then another battery to power all the Sbus servos on the starboard side, and another one to power all the Sbus servos on the port side. Not a perfect system, but it is still simpler than running long servo leads to each individual servo, and it has some redundancy (much more than I am running on any of my current airplanes), and it doesn't pull high amp loads through the receiver's bus. I will also be considering the Robbe power system too, since it offers true battery redundancy.

RE: Running a turbine at full power non stop? Damaging?
If you want to know the fuel consumption at full throttle without running the entire fuel system dry you can simply put a known amount of fuel into a ground/taxi tank and run a stopwatch to time how long it takes to drain. 1)Put a known amount of fuel into your ground tank (say 6 ounces) 2) Start your turbine without the ground tank attached 3) Run up to full power then attach ground tank to the vent line and start the timer 4) When ground tank is dry stop the timer 5) Do the math 6) Profit.[:D]

RE: FUTABA 18MZ HAS ARRIVED
[quote]ORIGINAL: siclick33 With regards to the batteries, do they only supply power to the servos plugged in the same hub where the battery is plugged in? Does that mean that if you want redundancy, as a lot of people do, then you would need a second battery pack (and regulator) at each of the 2 hubs and the receiver. That means a total of 6 packs and 6 regulators[X(] I would be more tempted to use a Powerbox with only 2 batteries up front. [/quote] You absolutely need one pack plugged directly into the receiver. You can use one or more packs to power servos at the hubs, and those battery packs don't necessarily need to be placed right next to the hubs or the servos. I would think it would be fine to put the battery packs where they need to be for balance and run heavy gauge wire to the hubs. I would also think it would be fine to splice several taps off of one battery to plug into multiple hubs. You could easily use one pack for the receiver (and any PWM controlled servos that are plugged into it), then another pack for all of your Sbus servos, or you could use two Sbus packs (one for the starboard Sbus servos, and one for the the port Sbus servos).

RE: What can cause a turbine to overheat?
Improper tolerances or bad bearings allowing the turbine wheel to rub the EGV could cause it, but you would most likely hear some bad noises coming from the engine, so I doubt that is the problem. I would suspect broken or clogged fuel tubes, and/or a distorted combustion chamber. Edit: Could also be FOD blocking the airflow. I have had an engine ingest a bunch of grass. I was able to clean what I thought was all the grass out of the compressor and the bearings seemed fine, but when I ran it it overtemped. I pulled the front housing off to find that there was grass wrapped around almost every stator vane.

RE: Has the extreme Heat stopped your flying
This thread is slightly amusing to Texans. [:D] With that said, I didn't fly at all last summer when we had a record 70 days of 100+ temperatures. It was not only too hot to be outside for any length of time, the entire state was a tinderbox and under a burn ban for about 4 months. Although there are no AMA rules against flying turbine powered models during a burn ban, I choose not to because of the potential danger. I have seen many turbine crashes that resulted in a fire. If a fire like that occurs during very dry conditions it can spread and get out of control before you even have a chance to get to the crash site. There were numerous wildfires in Texas last summer. Many people lost their homes and some even lost their lives. Those fires started by natural causes or arson, I can only imagine how bad the fallout would be for jet flyers if even one big wildfire gets started by a turbine crash. I don't want to be "that guy".
