RE: Extreme Composite Pegasus
[quote]ORIGINAL: 2Sunny Plus I'm doing a half hour a day on RealFlight 4.5. I have the Pheonix sim as well, but I like the feel of the Jesky Krill Spark in Real Flight better than the Integral on Pheonix. The sim isn't much good for a whole routine, but I'm practicing slow rolls and four point rolls as close to me as possible and right off the ground so I feel like I'm getting some meaningful muscle memory. It's kinda cool 'cuz I hooked it up to my giant flat screen TV and I practice standing up in my living room. Almost looks real sometimes especially with the "Photofields", but we'll see in May how much value the sim practice really has . . . [:D] [/quote] You should find the sim to be an excellent means to learn the timing of inputs and getting you beyond the point of having to think about what you should be doing. I also use the Jesky Krill Spark Evo in Real Flight. I modifed the model attributes to reflect more my taste in sensitivity and feel. I have modified flight models for the stock TX and also for use with my JR 12X. In the case of the JR12x i used some of the transmitter mixes to give me idle-up, rates, and also to dial out some of the knife edge and downline pitch coupling. I would be glad to send them to you if you are interested in giving them a try. I did something similar for a friend flying the BVM bandit on the JR 12X. I modified the model for use with various 12x mixes, etc., and he was very successful in using the sim to remain current on his Bandit. I also practice low and close at times to become more refined in recognizing the need for input. But it is also good to be sure to push the aircraft out and fly at a distance and height that reflects the real deal. The perspective changes and it impacts recognition of the need to make corrections. So long as you understand the limits of the particular simulator that you use, and prevent yourself from using the sim as a crutch, it will serve you very well.

RE: Newbie to Electric Pattern
[quote]ORIGINAL: dakoris73 Thanks again, and looking forward to hearing and learning more about the various setup options for battery charging. Mikey [/quote] I spent the last half of last year getting back into the hobby after a 10 year absence, flying my first electric (WInd 110), and practicing the Sportsman pattern. I expect sessions spent practicing to be at least 10 times that of actually competing. Therefore, I oriented my battery/charging requirements to facilitate how I spend most of my time. I like to practice in intervals similar to the way a runner practices for a race. Relatively short, focused, intense sessions. That means I fly, rest, fly, rest, etc., and the rest periods are fixed, not variable. I started off with three flight packs and found I prefered to get in at least a 4th flight, and a max 5 flights for a practice session. I routinely fly 8 minute flights. I don't like charging at the field. So after a half season of using 3 packs, I opted for 5. I place priority on what I need for practicing the way I like to practice. The contest scenario is therefore the exception. I also opted for the Powerlab 8 charger because of its parallel charging capability. I can charge 3 flights packs at 1C in less than an hour. I do all my charging at home although I do carry the Powerlab with me to the field. There is now a less expensive PowerLab 6. Lots of options but I strongly suggest that you not skimp on your charger. You can always offset the charger investment by making an initial purchase of less expensive batteries or a small number of batteries. Over time you can build up to the level of packs that suits your practice and competition style/priorities.

[quote]ORIGINAL: jmcmike Hey Guys, I know im late to this party but I just picked up a nib wind 110 red version and im gathering parts! Came with a nib recomended hacker motor so I will be going the hacker route and wanted to know if I can use my existing castle 85hv and 3850mah 5s thunderpower batts or will I have to go buy batteries with more mah? I dont fly contests but am a closet pattern fan! Thanks MIke [/quote] I fly a Wind 110 with stock motor on a 10s setup using Power Unlimited batterys (4900 mah). I fly Sportsman. If memory serves correctly, the sequence takes about 5 min 30 sec although I routinely practice with 8 minute flights, landing with ~60% spent. I would extend the time on each flight but 8 minutes really is enough. With the 10s setup I turn an APC 17x10 prop. No heat problems. That motor is actually rated by Hacker for 8s through 10s setups. Be sure to check the balance of the included spinner and backplate as well as check balance on your prop. I have no vibration problems but others have. Also check the glue joints around the firewall mount. Finallly, depending on kit you may or may not have appropriate M4 bolts for mounting the motor. I did not. Chris Moon (F3A Unlimited) gave me the tip to pick up M4 Pan Head hex bolts from the RC cars section of the hobby shop. Worked beautifully. You are lucky - it appears the Red Scheme is no longer available!

RE: How weight affects YOUR participation at NATS
[quote] Sometimes the only answer is "because that's the way we do it". In every other nook and cranny of the world where pattern is flown - from Norway to Nigeria to Malaysia to South Africa to Bora Bora - these rules are simply understood and followed because that is what we, as a collective community of like-minded hobbyists, have agreed that we will do. Seems to work everywhere but with a small minority here. [/quote] This reminds me of the many conversations I've had as an element of my professsional life. Any justification for a rule/activity that is enforced/performed which amounts to "because that's the way we do it" or "everyone does it" immediately raises red flags. The interactions/conversations typically go something like this ... Q: Your process, means and methods were analyzed and we found you do "X" but we are unable to determine the value in doing "X". Maybe we missed something. Please explain why you do "X"? A: We have always done "X". Q. But what purpose does "X" serve? How does doing "X" improve the quality of your mission/business? A. Well, when I came here we were doing "X". Now that I'm in charge we continue to do "X" because I see no reason to stop doing it. In fact, I have instituted improvements to do "X" better. Q. Interesting. So how does doing "X" better impact your bottom line? A. Well, we instituted changes and are doing a much better job of accomplishing "X". We cut costs by 1/4 and are more efficient at doing “X”. Q. So you cliam you have improved how you do "X", but you can’t correlate those improvements in terms of bottom-line benefit to your mission/business. A. Well, if you put it that way, no we have not. Q. OK. You brought us in to review your process and suggest improvements. We find no mission/business justification for the investment you make to do "X". We recommend you stop doing "X". Will you give it a try? A. No, we can't possibly do that. We have always done "X", everyone else does X, and I'm not about to change it. Besides, I can find many people around here that can explain why we do "X". Perhaps not to your satisfaction. But we do HAVE OUR REASONS. As a relatively new participant in the pattern community I'm monitoring this discourse from a cost/benefit "value-added" perspective. RIX is asking the right questions. But he is getting no meaningful answers. Responses - yes. Answers - no. Each rule should directly achieve or contribute to achievement of an objective and should have rationale for how it is intended to acheive that objective. Doing so provides the means to "test" the rule periodically to determine if it is serving its intended purpose - and provides a platform for subsequent improvement of the "overall process". Anyone subjected to adherence to the rule should be able to obtain a clear statement of objective and rationale for that rule.

RE: Prop question
[quote]ORIGINAL: g_mkoch Hello I have a falcon prop 20.5 x 14.5 on the way and was about to order a true turn spinner for it but they don't have the slot size on file. Is there an apc that is similar so I tell them to do the slot that size. I don't want to have to dremel the spinner after I get it. Happy landings. [/quote] It will fit just fine. I found that the shape of the prop blade as it passes through spinner is the same on an APC 16x10, as it is on an APC 20.5 x 14.5, as it is on the Falcon 20.5 x 14.5. And there is room on both sides of the prop so that the spinner can be positioned without actually contacting the blades. BTW: tru-turn offers "TurboCool" spinners that include cooling holes. They are available but the web site may not be updated to show them. Call Tru-Turn to order.

RE: Extreme Flight Vanquish 2m Build Thread
[quote]ORIGINAL: pvogel Thanks Michael. I'd seen similar threads as well, that's part of why I want to take this path. My biggest concern is I cannot find a real equivalent to the 9411's for the ailerons the 3711 is .11 inch shorter in length from the 9411, it's also considerably narrower and very slightly (0.02") taller than the 9411 will the servo bay accomodate it? Peter+ [/quote] Peter, I had considered using those HV servos in my Wind 110. They would have fit. I opted to go with the 9411 because I had a pair on-hand. For mounting servos in the wing servo bay, I usually make a 1/8" light ply faceplate that I glue onto supports in the servo bay, and just drop the servo in to rest on that faceplate. I don't think the 0.02" difference is significant, but if it were, I would just add a 1/32 spacer to raise the servo. 1/32" is 0.03125 inches.

RE: New Hacker ESC Senstrol
[quote]ORIGINAL: bjr_93tz "Constant Power Management the controller simply holds the RPM adjusted by the transmitter stick irregardless the flight situation the plane. For example the plane is flight into a loop then the controller holds the RPM by putting more power on the motor and also holds the RPM when going downwards again by given less power on the motor. F3A pilots who need this constant speed flight situation will welcome this." When I see "holds the RPM" and "need this constant speed flight" then it's pretty clear what their implying. [/quote] I think you are reading intent that is not intended! Full scale aviation refers to a constant-speed prop. That is a prop that has variable pitch and is controlled by both a power lever and pitch lever. The airspeed of the aircraft is not what is kept constant by having a constant-speed prop. It is the set-point RPMs that are kept constant. So we have the case where the term "speed" is used to refer to maintaining a set number of RPMs. I think the intent of this device is precisely the same. the difference they cannot obtain that by varying pitch for a given power setting. They have to measure RPM and adjust power to maintain the desired RPMs. What Does "Constant Speed Propeller" Mean? It means a constant RPM (revolution per minute) system that permits the pilot to select the propeller and engine speed the pilot wants for any situation, and then automatically maintain that RPM under varying conditions of airspeed and power.

"Back in the day" when flying glow I used at least 10 different types of soft mounts over time before settling in on the Hyde mount. The Hyde mount secured the engine at two points and was both firm and allowing very limited movement. I used other soft mounts that allowed very visible movement at the lower RPMs - scary movement. But - they held and were overall secure.

RE: Props for Hacker A50-16L 10S
[quote]ORIGINAL: gaRCfield Looks like that prop works. How did it feel? I don't remember what the max power is for that motor, probably could afford more but I'd be concerned about any more heat. If the 17" prop feels good, I'd say that's as winning setup. [/quote] Generally, the plane flies well, presents well, seemed very stable at slow speeds. I saw no tendency for it to float on landing. I will need some more flights to get a better reading. As for trimming, it needed a lot of up elevator and just a click or two of right aileron. One trimmed inverted flight only needed a touch of down to maintain level. Today was not a good day for checking up/downlines; higher up the air was turbulent and the winds were very different than down at field level. Besides, I need to fine tune rates - I was overcontrolling on elevator and rudder. Rudder was just too sensitive even on low rate. Elevator I did not bother playing with the rates because I did not like the fact that it needed so much up trim. That kinda bugged me out. I'm not sure if this is indicative of a CG issue or something else. CG is set at the middle of the wing tube - but I'm going to double check and be sure, and go from there. Aileron is just fine - very good roll rate/response across the speed envelope. I guess the speed was about right; 5:30 to fly the Sportsman pattern seems reasonable. I do need to tweak the throttle curve although I liked how the motor responded at the low end during approach/landing. I could set/maintain pitch and blip the throttle on final to control descent.
