hi 

"The wooden prop is a fair way down on efficiency compared the the composite prop- it bends.  the composite prop is a great upgrade."

the prop on the J-160  i understand was replaced in recent past so i`m wondering what prop i have fitted  ( are no`s easy to read without removing the prop ) 

i had composite prop on my previous J-120 aircraft  (definitely agree on up-grade )

 will get a set of no`s  next flight  (cost of fuel is not making it easy to fly for pleasure at the moment  in the bush - $3.60 P/L)

what type of J160 is it - does it have a 6 cylinder or does it have a 4 cylinder ?

i have the std 2200 offering 

 

I would expect you would get 90 kts indicated and 15 lph.

I have some questions : 

 

1) What indicated airspeed does  do indicated at 16 lph ? (what fuel # pax also approx) 

would need to do another flight & record some more numbers  but as i remember quite slow 

2) What is the static RPM -  RPM at the beginning of the TO toll, WOT . ?

I woudl expect 2850 for the 6cyl, and ~3000 for the 4 cyl. 

3000+ a bit variable  most times 

3) what fuel are you using ?

 i use avgas in the bush & mogas 95octane or 98octane if near town & i can cart 

 

-glen

 

if the aircraft will easily go 3300 RPM, is MIGHT too fine, and the prop is likely a very inefficient screw in that setup, depending on the IAS

 

 

 

 hi 

 yes  that is correct . if you want a security measure  then replace the wing nut assy with a security torque bolt of same thread then it is impossible to get cap from the filler neck

hi 

 the J-120 hardly ever seen RPM above 3000 & went everywhere at 2800 rpm  i replaced the wooden prop with the Jabiru plastic option 

 the J-160 will go to 3300RPM  full power  easily so cutting the rpm in cruise to  2900 rpm is where it seems to like it  using  20-25 l/phr . using 2800 is slow & 16-18 l/hr approx i have a wooded prop fitted don`t know if it is correct or not 

so have a few variables to consider & weather is windy so not good for comparing numbers 

hi all 

i have recently acquired a J-160  on the couple of flights i have had it has used fuel at about 20-25litres /per hr . i  compare this to the J-120  i owned previously  which was in the 13-15 litre range . i know the airframe is different  but when i read on the internet the quote is around  16 litres /hr . i haven`t looked into the internals of the carbie yet to see if jets have been changed or not , how do i determine that jets are worn or what is wrong ? the burn rate seems high based on what i can read it should be 

 your thoughts please 

lyle 

hi 

this is the latest offering from radiant instruments  it might be what you are looking for https://www.radiantinstruments.com/product/flight-sensor-pack

allways pricey as everything is built by hand but quality & great company to deal with 

hi all 

 who has recently fitted this Up-grade Kit from Jabiru  what are your thoughts on this kit ??

 is the matco offering  a better alternative ?? (more $$$$ i know & engineering to fit )

HI All

as there seems to be a group of us who have EQ-1 headsets  with no ongoing support apparently .  we perhaps should backtrack to find why the sale of business  means that the current owner  would not be interested in keeping this excellent product supported & selling more of them . it is not as though they were cheap chinese knock-off`s when they were being made & marketed by great people & companies 

where do we start in the search ???

hi

it seems the batteries fail 1st  i dont seem to have any other issues apart from battery  issues 

they are an easy swap for anyone that is electronically -mined  handy with a soldering iron 

hi RF-guy 

thanks i have already determined that the batteries were AAor AAA but they are hardwired & made into a battery pack 

 i however am not confident in creating another battery pack to solder back to board 

hi all 

 as the people involved with the EQ-1 wireless headset project have all gone their own ways & no agent available to do repairs who do i approach to get the batteries replaced in wireless link 

 thoughts & ideas 

 thanks lyle

what is an EKIV? post pic please, maybe I can make a suggestion.

 

hi 

what is an EKIV?      a GPS  moving map before OZRUNWAYS which was popular in past  made by AVMAP

not my dash but same GPS in centre dash 

hi all 

i have an avmap  EKIV  fitted  to a J-160c  it has lost the toggle button in the lower RH corner of screen

 is it a simple process to get replacement or is dealing with manufacturer an option 

 or ditch unit & fit a replacement 

 what will fit to the existing mount with a minimum of modification 

 what has anyone done ?

 give me your thoughts & ideas

Remember the test switch only checks the bulb is good - not the sensor.  In 600 hours I have only had the warning light come on twice, when unplanned.  On both occasions I picked up the warning while it was in the flashing state - prior to becoming steady. The light is in the default location. ( I would move it if I built another).

 

I'm currently mounting sensors on the outside tanks to give a 5 litre warning.  They will not be very accurate but will at least tell me when those tanks are empty. I can set those up so that a light goes off when the level is low, so it is reasonably fail safe.

i have bought these to use some time they are low level warning light & sensor (new version is ultra sonic prev. ver was sensor)  https://radiantinstruments.com/bingo-4-liquid-detector/ they have a whole range of instruments as well  see on the website 

this my be of interest to you 

hi 

 who out there has these headsets & have you had any contact with anyone apart from the chap at white gum caravan park( who is almost uncontactable ) i have issues & need to get new contact details for the new agent  (i was advised earlier that a new agent was taking over 

any help appreciated

 lyle 

hi all 

what are your recomendations for an epirb that is at the cheaper ind of market that does the job 

thanks 

hi all

 my ipad failed after many years faithfull service ( currently 2nd Gen ) i need to source another unit  do i go for a new unit ?  a second-hand unit which model?  a refurbished one which model?  

can you leave your ipad on charge when not in use  or is this a NO  NO ?

give me your thoughts on how you would replace  on a budget / holidays 

fred at wagga bikes & tyres is definitely the person to go to for anything tyre /tube related  he knows his stuff tell him lyle sent you  i don`t go anywhere else  he knows his stuff  on anything aviation related

Lyle the CS prop question would need some context -

i was always wondering if there was any benifits to fitting in place of the jabiru plastic offering which was an improvement on the wooden one .having the pitching better matched to the motor requirements  with a C/S type  in the various phases of the flight 

i`m aware off the rotec  TBI system   there is another rather exotic system that the use in south africa 

hi all 

 i think about these mods from time to time 

are any of you running a fuel injection system  which type ? was it worth the change ?

 has anyone tried a C/S prop conversion any benefits? which one did you use ?

there doesn`t seem to be the interest  in replacing the carburetor 

hi all my fellow forum readers 

 i find my self in a delima  with an expired BFR   new plane to take delivery of & COVID to deal with in achieving the aforementioned 

 is there suitably Qualified  people  about that would travel to conduct a BFR  in a remote location or near by 

 let me know your thoughts or if you can help 

 PM or forum your ideas 

 thanks lyle 

hi 

2 sound barriers ( as reccomended for out door setting under dome shelter ) & security system for activation  tad under 6K  expensive but if it works then i will be in frt .

go to  this site for info etc http://www.sonicforcesecurity.com.au/index.html

the distributor is a very knowledgeable chap about his product  tell him lyle sent you his way 

yes  all the comments on checking fuel qty before flight is a no-brainer  check before you fly but the point of this post  is the popular past time of removing fuel from aircraft`s  & all the damage /loss/stress that one can be confronted with when you arrive at airport to go for a quick fly & then you may need to repair your aircraft or replace fuel  this doesn`t put you in a good mental space to go flying . so i have had to go the costly path of a DETTERENT to keep my plane safe so i can just check & fly without a constant repair everytime i wanted to fly 

hi 

 yes i have also been the victim of fuel & damage at my remote  home hangar  i had to get the plane out of there until i have installed a deterrent device  called a "sound barrier " which i believe will save me further damage loss . reports in our local paper of similiar device when its suspected use by russia & china on american diplomats  produced mysterious dibilitating side effects requiring medical assistance (not permanent )  this i hope will convince them of the error of their ways
