RE: What is the FUTURE of our Hobby?
"This Poll is gay and I dont care!" is winning! Hilarious! I voted for that one too, just because... [:D] Actually, I think that the first option is the right one - this segment of the hobby, like all, will survive in some form. The economics of jet flying are actually getting a bit better as more choices, and more used equipment become available. I think you're seeing the results of that in the increased attendance at selected jet meets. The biggest threat to turbines remains regulation by the Feds, but I'm hopeful that the AMA can help head that off... Bob

Lowell, I'm a member of RARC which has a field in Charles City. There are 3 or 4 jet guys in that club and we sometimes fly jets out there. Its a grass field though so the ones we fly out there have to be grass-field capable, which not all of the one we have are. We also fly occasionally off the hard surface down at Ft. Pickett and last weekend we went to Fentress in Chesapeake for an impromptu jet flyin. Send me an email and I'll put you in touch with the other jet flyers in the area and we can let you know the next time we go out... Bob

RE: Fuel tank Plumbing
I *did* have a problem with the two saddle tanks on my F-4 draining equally, but I have not had that problem at all on my FEJ F-15 - both tanks are as empty as possible when I land. I think it might be the fact that the saddle tanks are above the center tank during level flight and that may promote better fuel flow from them into the center tank in this airplane... Bob

The throttle stick was not moving but steady at 91%. So why would the voltage drop? The battery voltage was steady at 8.3 V. It was a cool day and had rained the day before. The ground was still wet. I do not think it was static. Nor do I think it was a radio problem as the state did not change from 11. So what could it be?

RE: Fuel tank Plumbing
I second the above - F-15 models are typically setup so that the saddle tanks drain first and then the center fuselage tank. Most of the time the center fuselage tank is referred to as the "main tank," but regardless, it should drain last. One of the reasons is that the center (main) tank acts as a "bubble filter" for the two saddle tanks - i.e., as the saddle tanks drain, there is an increasing probability that one of their fuel pick ups will suck air as the plane banks. The resulting "bubble" goes into the main tank instead of the UAT and when the plane levels out again, the saddle tanks will continue to provide fuel to the main tank. If you do it the other way around, you'd likely run out of fuel in the UAT long before the saddle tanks are empty. With the saddle tanks plumbed into the main tank, you'll usually drain the saddle tanks almost completely dry before the main tank empties and the UAT will remain completely full (assuming that the pickup in the main tank is done correctly). You can balance the plane with only the UAT full and you still should not have any problems landing with the main tank almost completely full. You should make sure that you have enough "up" throw in the stabilators though. I fly my FEJ F-15 with all of the "up" that I can get - it does high alpha stuff really well with that setup and it only takes a reasonable amount of expo to calm it down for normal flying and landing.

[quote]ORIGINAL: jclittle [snip] again just do not 3 point it, you will regret it. [/quote] This is key here. The Kingcat can get into a repetative bouncing situation that can end in disaster. Just be sure to get it slowed down on landing and touch down on the mains only. The Prolinks will help that somewhat. Also go easy on the brakes - it will slide sideways or even ground loop with agressive braking at higher speeds. Actually flying them is not a problem at all - they go straight as an arrow and are extremely docile at low speeds... Bob

I normally use the 350 mA variety of the luxon emitters, but for really bright landing lights, I sometimes use the 750 mA variety.

Skymaster Jets are good too and you can get service (i.e., parts) from BVM, so that helps.
