The DB instructions for my constant speed prop, advise that the DB be done, at Cruise RPM, with the prop on the fine pitch stop. Having followed the instructions, I thought I may digress and see what happens when the prop is turned to a Crusie pitch setting. The vibration increased marginally - still well within the recommended level. I have writen to the prop manufacturer, asking why the prop is not balanced at the Cruise prop setting, where I spend most of my flight time - early days, yet to have a reply. I thought this might be a good topic for the Forum to discuss/nut out. Any thoughts? 😈

Thanks Mkennard, I have a vague idea for a flight north, staying out of DRA to Khancoban. - Entering DRA to Adaminaby. (Paralleling Canberra eastern CTA boundary - . Out of DRA) - Braidwood Percheron - Mittagong - Spectacular country. Highest point Jagungal 6788' Extremely weather dependant - will have an alternate, further west (low country) route.😈

Where to find a map showing Vic/ NSW Designated Remote Areas (Snowys)? 😈

Thanks for the info. Marty_d. Tad pricey @ $57.65/day ($88.25/2day) ticket, plus landing fees and the cost of flying in. There should be a concession for fly-in's, as we provide some of the attraction ("... drool over your plane!"). Strangely the Gold Pass price is the same as the proletariat price. Arrivals between 08:00-10:00. No departure advise, however air show ends at 16:00 so presume anytime after this. 😈

About half way through my 200hr service. Part of the service is to "dry lube" all the control systems moving parts - to this end all inspection covers will be removed / replaced (ugh! - far too many screws, will have RSI by the time I'm done) including the whole seat pan. Removal of the seat pan will expose the cockpit flight controls linkages/rods/etc. This will give me a chance to work out, the bungee cord routing, location of pulleys & cam cleats. If it's possible, I will have a bungee on the left rudder system & on the right aileron / up. It's going to be tight - will let you know.😈

Never mind the fancy war machines, Russia has along a bloody history of using its own as cannon fodder - doing much the same against Ukraine. Ukraine can not hope to win against Russia. The best they can hope for, is to repel the invader, even this won't happen, without boots on the ground help from the West.😈

In resents times (last 3 months or so) my little airfield has been sloooooow. In part weather but also reduced activity by possibly the most active of two flight schools. In short, not too many people arround.😈

"what is the best prop for cruise and top speed. i always believed 2 blades to be more efficent than 3 and 4 blades. i am talking fixed pitch or ground adjustable." Like you I have been told, over the years, where clearance, tip speed and power can be accommodated, two blades are the most efficient = converting given power into forward/flight speed. I believe the type of airframe (draggy / slippery) and the intended mission objectives (STOL / high speed cruise) are likly to need to be considered in the prop selection process. I would always go for ground adjustable over a fixed pitch, as it seem to me that even within a known airframe/engine combination, there will be variants in operational conditions, that the pilot/maintainer can fine tune the prop for eg advantage take-off, for short or compromised strips. In resents times the E-prop would seem to be gaining a strong following. I still find it astonishing that the "toothpick" blades that characterise this prop, can deliver the reported performance improvements over more conventional shaped prop blades. 😈

"Realistic temps might be seen on full power ground runs." They may or not. I speak as someone with an experince, where satisfactory ground temperatures, were not translated to flight. The first test flight was cut short due to excessive in flight temperatures. We tried all sorts of cowling mods, ducting, etc with only minor success. In the end, a complete cooling system rethink/design was sucessful. In your favour, you are building well know/tested aircraft. If you have not strayed to far from the plans, all should be well. If on the other hand you have allowed your inner experimenter to take hold, be prepared for the unexpected.😈

Anyone watch 7:30 report,on this incident, last night - RAA in bad odour.😈

Thanks Thruster88, Not being in the first flush of youth, something like "Spotify" seems to be from an alien planet. I don't use the Am/Fm radio in the car ( except occasionally on very long highway trips) let alone in an aircraft. I was hoping that there may be other users "out there" who could give me the benefit of their 😈

I have purchased a Six Aviation Bluetooth Headset Interface for my David Clark headset. When switched on, it announces its on, however I have yet to hear anything from the system its Bluetooth connected to. My iPad shows its connected to the Six Couple of questions; How can I asses its working correctly? Has anyone else experince with this device? If so please share.😈

I don't know the answer to your question. I am lead to believe that the big two (Ly/Con) are very much in the 'grandfather's axe' territory. To acheive their claimed TBO, it's not unusual for costly major "surgery", described as routine maintenance, to be conducted.😈

As for aircraft colours - There is a colour, at each end of the visible light spectrum, that humans seem to gravitate towards - black & white. It could be argued that both demonstrate a lack of imagination in the chooser, however I would suggest; Black - conations of death & violence. Very dramatic. Absorbs heat, shows every scatch / spec of dirt, hard to maintain and has low visibility, in certain light conditions. Much loved by those wishing to project a hard image - Totally impractical. White - conations of purity & peace. Totally boring. Reflects heat, doesn't show dirt, relativly easy to mainatine and has relativly high visibility in most but not all climatic conditions. Very popular with the utilitarian leaning crowd. Possibly the most practical colour to paint an aircraft (any vehicle)😈

You digress- the topic is lights, not paint/colours Despite the empirical evidence (could be out of date) that lights on day VFR only aircraft, do little, if anything, to assist in air to air visibility, pilots still love fitting them. Good -on -em! 😈

Word of caution: Ground runs / engine temperatures are not necessarily indicative inflight performance. 😈

More than fish bones - a few adult chicken bones as well. The test was however impressive, the "blob" (scientific description of a lump of gelatine) hitting the prop tip, delivering considerable force to the blades most vulnerable point.😈

Perennial debate - Do small aircraft lights (strobes/wigwags) actually confer a significant benefit for aircraft to aircraft (air to air) visual capture in day VFR conditions???? Many say yes, especially if using modern LED technology. Past research says no, however may not have been done with modern lighting LED systems. There is no doubt that lights are effective for seeing an aircraft from the ground or in low light (VFR?) conditions but air to air????? We instinctively think that lights will improve an aircraft visibility, we compare with ground based vehicles and argue something is better than nothing - none of this is science based. Current Australian regulation do not require day VFR aircraft to be fitted with lights - I believe this to be a reflection of the research ( as stated may be out of date) Personally I think that the best visual capture system, for day VFR, is good radio communication - this gives the pilot a clue as to the other aircraft location in space, thus minimising the area to be searched.😈

If your a VFR day only pilot - save your $$$$😈

" The cable price is $1488.30. WOW!!!! that hurts & I'm not even the purchaser😈

I try not to make dogmatic statements, however in this case both your instructors are just wrong. "....never used unless there was an engine problem that needed sorting out inflight" The whole point of carby heat is to preempt an icing problem - it may be far too late to fix a carby ice problem, once symptoms occur, as availability of hot air may have already reduced and time to clear ice, may be insufficient to prevent forced landing. "For every take-off, landing and maneuvers both were turned off." Carby heat on take-offs is a highly unlikly scenario - high engine power and icing do not usually go together - so okay not to have on. Always use fuel boost pump (if fitted) on take-off/landing and when conducting manoeuvres were a failure of the mechanical fuel pump may jeopardise continued safe flight (close to terrain)😈

My comment only applies to engines fitted with an in flight, pilot controlled, carby heat system. My current Rotax has the liquid heated inlet manifold - so no in flight carby heat control.😈

Great news/terrific report Moneybox. One small point (can't help myself) "Even though I was taught to not use the carby heat I pulled it on when turning base and off half way down final." I have no idea who or why you have been taught not to use carby heat - makes no sense to me. If the aircraft you are flying, is fitted with carby heat, it should be used. There is no down side to the correct use of carby heat - basic safety / common sense. Make using carby heat a safety habit. Correct use - in flight, carby heat should be used before reducing power ie you likly reduce power on descent to circuit height or on down wind, before slowing to safe flap speed, before practising stalls, etc. For best power delivery, carby heat should be closed ie as you did, on final, just in case of a go round. Reasons - Your carby heat (hot air)is likly comming from your exhaust system. When you reduce power, your exhaust system will cool quickly ie its ability to deliver hot air to the carburettor inlet is reduced. Apply carby heat when exhaust at high temperature. When you you close the throttle, there is an increased chance of carby ice formation. Apply carby heat when carburettor delivering high power. I have experienced carby ice, before first flight of the day, in the run up area. So far never in flight. 😈

No nibbles???? Price? - check out one from a retail outlet. I am open to negotiaton😈
