RE: 55AX mid throttle issues, fixed I think
[quote]ORIGINAL: flyboy9994 Hey Bax Brand new 55AX broken in per manual, maidened in a new airplane, first 3 or 4 flights fine with no incidents. Engine suddenly starts dying at mid throttle, right where I like to fly. Here's some background: Can easily duplicate on the ground. Cowl removed to observe fuel line and absolutely no air bubbles or disruption of fuel when engine quits. Engine does not hesitate or sputter, dies like a light switch turned it off. Good idle at around 2800/3000 RPM. Perfect transition to full throttle with no hesitation, Perfect full throttle flight at around 9000/9500 rpm adjusted slightly rich from max rpm. Tried pretty much everything: tuned needles, changed glow plugs numerous times and they looked perfect (OS #8), re-built entire fuel system. Removed and cleaned carb, nothing found. Raised tank to get it in-line with needle valve. Flown with cowl off and engine is definitely not overheating. Same exact problem. Still dies at half throttle... Here's the kicker: Changed to an OS F plug and problem instantly solved. Put her back together, cowl installed and 10+ perfect flights later with absolutely no mid throttle problems anymore. Do you have any ideas why the F plug would have made such a difference?? Randy [/quote] Yep . . Mine and others I know of do exactly the same thing. For what it's worth . . i have ALWAYS run an 'F' from my pre EP Pattern days. It's no good for slope soaring balast . . any other ideas ???? JB

RE: Angel S EVO Build Thread
I have only ever used 5S in this plane, and everywhere from Flitemax 3000mAh to Zippy 3700 & 4000, and Hyperion 4350mAh. It lands much nicer with the 3000 pack and is a little more "fun" to fly . . but the heavier packs are better for pattern. It penetrates so much better and carries momentum over the top of manouevres. I will try the 5000's out of the 2M planes soon . . but I expect it will be difficult to do a nice graceful 'greaser' landing with even heavier packs. I imagine 5000mAh [b]6S[/b] would land fairly 'hot' on calmer days ??? JB

RE: SAP 180 (Syssa Performance)
Bob . . having used velocity stacks before, it does little (on it's own) to improve intake noise. The inlet track needs to be baffled. i.e. the air gets in, but the sound bounces off the baffled 'bends and twists' . . or at least that's what appears to happen [8|] We have even found a 'baffled', unfiltered air box to be much quieter than just an air filter on it's own.

RE: Is 4000mah enough?
[quote]ORIGINAL: Nathan King I'd wait for the five amp batteries. I know a guy that used 3700 mAh 10 packs in his Integral. All was well until he flew at a competition that was really hot and windy (30+ mph winds). It turned out that day that 3700 wasn't quite enough for his routine. He puffed the pack. [/quote] Yes . . if Joe is flying a 2M, but I believe it is a Wind 110. The Integral is 1kg (2.2lbs) heavier and has more drag than the Wind 110 (Wind 110 has MUCH thinner wings). That makes a big difference. Also . . same friend tested his 10S 3700mAh and 4900mAh Rhinos in his new 2M Wind S Pro / Plettenberg / Schulze ESC in windy conditions flying F3A P11. He was surprised. Commenting that the lighter total weight using 3700's (lighter pack weight) drew less Amps, although the Wind S Pro is less 'draggy' than the Integral . . that's for sure. JB

RE: Is 4000mah enough?
Hi Joe, Depends really . . you have a Wind 110, right ?? Is it 8S or 10S?? A friend of mine flew the Wind 110 in F3A with Rhino 3700mAh and it was fine. He started with 8S but wasn't that happy with it. He upgraded it to 9S (yes 9S ! ) and finished with 10S . . all 3700mAh Rhino packs. He then went to 10S 4900's, but only because he had them and liked the way the Wind 110 flew with the extra weight. If you are using 10S, 3700mAh Rhinos should be fine . . If you are using 8S, the 'cheap' 4000mAh packs may be border line. Of course you can drop the current draw, but you probably wouldn't be happy with the performance then . . JB

RE: Two Half Rolls
What airplane are you using? Is it in a 45deg upline or downline? or horizontal? If it's a good (and gotta be well trimmed) 2M airplane and it's in the 45's it should just about be fine with aileron only (maybe just a slight adjustment 'squeeze' here and there [;)]). If you are adding rudder/elevator out of habit, it could be throwing you off? If it's in the horizontal, yeah could be a "feel"/timing issue .. or maybe badly trimmed? (just thinking). Otherwise, practice and get a pattern friend to note when it's happening and reference what you might be doing at that point ?? [8|] . . and then practice some more [:D] JB

RE: SAP 180 (Syssa Performance)
[quote]ORIGINAL: JFisher304 You would have to make a choke plate that would cover the holes in the air box. We choke our kart motors by placing our hand over them. In fact, on direct drive karts we reach over and choke them slightly going into corners so they are just a bit fat when we get back to the throttle. You get a little extra torque for the drive off. [/quote] Yes . . a kart racer for 16 years, I can attest to that. Images below are of a typical air box and adaptor. I am not sure, but with an adaptor like the one pictured, I think you could still leave the choke baffle in place ?? I can hear intake noise on my DL1OO and was thinking about making an "air box" out of an old film container. Remember those? [8|] . . Maybe not enough volume, but you get the idea? PS . . Yeah, choking the kart by hand at the end of straight sections . . keep throttle open as you hit the brake marker, hand over airbox as you brake with throttle still wide open . . hand off airbox and power thru apex of corner while 'tapping' other karts [:D]. Almost makes the F3A-P11 integrated half roll in the figure 'M' seem easy ! [;)] We did this mainly with aircooled engines to bring the cylinder temp down (sudden large dose of fuel) . . rarely choked a water cooled. JB

RE: Wind Correction - Stalled Maneuvers
[quote]ORIGINAL: Nathan King I often find myself in quite a pickle with gusty crosswinds. I correct very well in most maneuvers, but the maneuvers that require a stall (stall turn, spin, etc) are giving me trouble. . . . . Can you do anything besides correct before and after the stalled portion of the maneuver? [/quote] Not much ! . . When the airplane is in the stalled condition it is not flying, so is at the mercy of the conditions. Relevent sections of the FAI-F3A rules are below . . ;) JB [b]5B.7.4. STALL-TURNS[/b] . . . . Drift of the model aircraft during the stalled condition must be ignored, provided the model aircraft does not drift outside the aerobatic zone. [b]5B.7.6. SPINS[/b] . . . . In order to spin, the model aircraft must be stalled. . . . . Drift of the model aircraft from the flight path at this point should not be downgraded, since it is in a near-stalled condition. However, severe yawing or weathercocking during the near stalled condition, should be downgraded by 1 point/15 degrees. [b]5B.8. WIND CORRECTION[/b] All manoeuvres are required to be wind corrected in such a way that the shape of the manoeuvre as described in Annex 5A. is preserved in the model aircraft's flight path. The exceptions to this grading criterion are in the stall turns, and spins, where the model aircraft is in a stalled condition.

RE: Servos For 2M
[quote]ORIGINAL: mdjohnson Some people say the metal gear train inherently has too much ''slop'' but the preferred JR 8411 has just that. All a compromise I suppose. Maybe the difference of the metal gear train is in the quality of a higher priced servo (JR) as opposed to a middle cost servo (Hitec) giving credence to the fellow that said ''you get what you pay for''. [/quote] I use JR 8411's BUT the "SA" version (DS8411SA). I believe it stands for "Special Application"?? These servos have a nylon gear train and I think this range was introduced for Pattern. I understand they are no longer available, however the Nylon gears from similar JR servos fit. I don't find the standard 8411's sloppy when new, but they do wear faster, particularly with the vibration of Glow power. With EP, I expect they would be fine, although they are heavier [;)]. I use the Hitec "TG" servos on IMAC as the 'Titanium Gears' give very good life with the vibration and load of a 35%'er. JR's new range of high torque servos have a "special" metal gear train . . so I am keen to see how these perform over time, but they are VERY nice servos although nearly twice the price of Hitec. JB

I am thinking that only a select few get "free" stuff, otherwise who are the "top guys" and the companies promoting to. Companies can't sustain a business giving a LOT of free stuff away . . they are usually very selective with how and where their profit is spent on promotion. Even at the World Champs, a lot of pilots pay for their own gear and these guys are usually the best from their country. I am sure that many have tried different servos and keep coming back to JR or Futaba for pattern. Apparently, Savox make some nice servos these days that some Chinese, Taiwanese and Japanese pilots are using in Pattern, with a couple having swapped from JR, so I read. They only swapped due to cost, commenting that the performance was EQUAL to JR (others may have swapped from Futaba???). I use both JR and Hitec Digitals for different planes. I won't use Hitec servos in a Pattern plane, and I pay for my gear . . JB
