  1. An Altimeter is the primary reference instrument for altitude.An EFB is not even a secondary instrument,it`s just for situational awareness.This pilot should have remembered that.He was reckless to reference to his EFB.
  2. You do not need to worry about adding any more ballast.Your weigher has done it all.I believe the Rotax engine with radiator weighs more than the Jabiru engine.That would have put your cog forward so to prevent that,thats why that ballast of 2.5kgs has been added.I have checked your cog with a pilot only with weight of 80kgs with no baggage and no fuel,it is 229.36mm which within both forward and aft limits.With 100l of avgas,pilot and no baggage ,it is 263.72 which is well within both forward and aft limits. There is nothing to correct unless you want to reduce weight of your ballast to move cog more forward.
  3. Interesting to find Airspace infringement and seperation being so high.We really need to be very cautious.Thanks,that is a useful Tool.
  4. Not sure what is going on with the Baroons.This is a fourth one if I am mistaken.https://www.9news.com.au/national/plane-emergency-landing-south-australia-aldinga-adelaide/f81b8582-d1a1-49ec-af94-7e4b5eafc653
  5. With regards to horizontal stabiliser,I had an aerobatic instructor show me the good design.The horizontal stabiliser needs to sit well above the wing level so that in a stall the turbulent airflow above wings does not inhibit rudder effectiveness as more smooth air is flowing to the rudder.The other design is the one pointed above where the rudder extends below the horizontal stabiliser,again letting smooth airflow past part of the rudder.These old instructors we have here are a valuable resource.Kev I will show you next time we meet at the club.
  6. Bill could you give Karl Faeth at ASC Gawler a call.He is our club's cfi.He will give the good tips.I did my Roko conversion with him and other instructors as well.Speed management is critical especially on shorter runways.
  7. So if it doesn't meet LSA standards,does it meet GA standards.What I have heard is LSA standards state or require an aircraft to come out of an incipient spin without much control input from pilot and enter into a spiral dive.A C152 is one such aircraft I know of though it's not an LSA.However some of the Bristels that have crushed were GA registered which means GA pilots are failing to recover.The Statwell incident I know of happened at very low height.I am not sure if they recover easily at height.I have flown a Roko which recovers at height but any unco ordination at stall,it drops a wing violently.I hope DJP will be able to share his views here.
  8. For the FK9 if you climb at stated climb speeds when the prop is configured to climb,you will have a much higher nose attitude.You will basically have no forward vision.All you see is blue.As a result you end up climbing at higher speeds when you lower your nose to have that forward vision.
  9. You made a typo which has changed the meaning.Anywhere you will realise what i meant when you fly a different type.Dont worry about it.
  10. I am signed off on that type.Jabiru 7252 has said it all.At Gawler we preferred not to use flaps for take off when the prop was adjusted for climb,however when they changed it to cruise we would use flaps but quickly retract them.The aircraft tends to have a steep nose in a climb.
  11. I agree with the above comments,the safest way should be to have off and on only.However the feed lines should be fitted with non return valves so that no tank is fed in during banking.
  12. Interesting Paul,I have said the same thing to my colleagues.I fly the Liberty XL2 well because I have flown the Roko.The Libery though is much steadier and balanced on stalls.
  13. For sure it should be interesting read.My club owns the sister a Roko NG4 which is only flown by members with 50 plus command hours.There is a general feeling no one should be practicing stalls without an instructor.It has violent stall characteristic especially when it yaws just before the stall.Lovely to fly though and stalls below 38knts.
