  1. First video out on the new Constant Speed Prop
  2. From the Rotax forum..where there are some very good Rotax experts
  3. The Eprop line are developed for the engine and gearbox as well. You will see the selection chart on their website asks you what version of gearbox you have. There are ones designed for different engines to take advantage of wich engines HP and also gearbox ratio...I think they know what they are doing and this is why you set the prop up to "THEIR" specifications not what your specifications are or you think they should be. Everyone who has set the prop as per the instructions has had a substantial increase in performance..the 2 that I know of who set it up their way...well they didnt get any improvement that every other aircraft got. RTFM .......Read the instructions...where have I heard that before
  4. The 5800 is only for takeoff phase thats all and in the scheme of things that is 1%of the flight envelope. 5500 is max continuous rpm. The eprop has been designed to give max efficency at that rpm range. The new CS prop being released next month will have different blades for sure. I will know when my demo arrives. Then you can go 5800 of course for that very short period on takeoff.
  5. yes the wings and other bits are a fair way from the fuselage...looks like a inflight breakup
  6. Those test results are run as if running a CSU type prop engine rpm not a fixed pitch prop. The Eprop is setup very differently. I have more than 25 people who can attest that they are at least 5kts and some up to almost 15kts better than the originals they had on the aircraft. A fixed pitch prop is setup very differently as you well know
  7. AcroDuster..thats hangared near me. Pilot did not survive 😞 RIP blue skys https://www.abc.net.au/news/2021-08-18/search-for-plane-in-distress-off-bribie-island/100386296
  8. Doesnt look good. Brisbane Times report a crash west of Bribie Island near Coochin Creek. The picture looks like it maybe a Pitts special from Caboolture...not sure though. I hope not as I think it maybe the one 2 hangars down from mine
  9. Try with a std Rotax first then if you need more grunt then do the bolt on HP with a big bore kit. Maybe also add a CSU later. I think adding a turbo later is a much bigger job and a lot of testing and fiddling to get it right. I know Todd has had a few issues from time to time with his turbo "add on" that required a lot more fiddling as he did have some issues and he had to do a lot of tuning to get the wastegate etc right. At least you can do this with a Rotax...cant do it with a Jab engine...I havent seen any bolt on and go HP increases for those engines
  10. Glenn Just look over in the USA. They are flying all sorts of aircraft in the LSA and Experimental also Jabs in far higher DA than your talking about. I think you are stressing way too much over the facts and figures...we all know that what you put on paper is maybe not so in the real world. So many I know over there their takeoff std height altitude is 6000 or 7000 ft so the DA is far worse in their summer and all have no difficulty doing lots of flying. Look at Youtube for Gravity Knight Flying. Todd used to have S6 with a std 912ULS and his home airfield is over 6000 ft and he flys 10 to 12k ft all the time. He has since added stuff to his engine and also now a different aircraft but his previous hundreds of videoes were done with a bog stock 912ULS. Just stick a rotax in it and go fly...I really dont think you will be dissapointed
  11. HA got nothing on mine...the wrecked Savannah I bought to repair was built by 2 LAME and it was disgusting in how it was built and the attention required...not to mention with a all CNC kit if it doesnt fit that means you have done something wrong. I totally pulled the aircraft apart to every single piece and remade all the parts..on my rebuild blog you will see some examples of the "workmanship" they used to build I believe 13 other kits. There are very very few LAME that I would trust to ever touch my aircraft
  12. Not yet skippy...only what is on the website After the release early next month I expect a lot more detail
  13. This was a long time ago about the incident above. Bolly were trying to develop a all carbon 2 blade for the Jabs. They have it solved now. The Eprop one is still in testing but not too far from being released. There is a airshow in France next month that Eprop is releasing the CSU version so maybe it maybe released there as well
  14. It says you dont need a primer for the hammertone but I did spray a etch primer on it first
  15. I just painted my dash plate last night with hammertone gray 🙂 The Girlfriend the first dash was painted hammertone gray as well I like it...but a later dash I made I got powder coated in hammertone..that was really nice. The dash I have made now is only a interim one I maybe changing the arrangement. The final dash will be powder coated again
  16. The one supplied for the Sav is only a single lead either side. Just dont use the other 2 if you dont want. As I said that 50amp is the last resort fuse...it protects basically against a dead short for anything past that solenid connection
  17. Need to do at least 5hrs conversion from RAA to RPL
  18. They must have changed them..I used them years ago on 4WD comms systems...they were a hell of a lot heavier than any lead acid battery..they had a steel outer case
  19. yes but it may as well be a boat anchor with their weight..they weigh about 9 or 11kg
  20. I prefer the 63V after seeing how big the spikes come out of the generator and its easier to mount than 2 of the others You can easily make a clamp mount out of 1mm alu Breakers from element14 maybe a bit expensive..they have nice name brand ones but they are very good
  21. Glenn is correct always try to get the 105deg versions but they are hard to come by...mostly are 85deg I just looked at Element 14 and they have some in stock...well not here but a week or so away in their stock overseas Element14 order code 2835151
  22. The cap is in the Rotax manual as a "optional " part..it needs to be a std fit because of the crappy generator. 22,000 uF at 40V miniumum but 50 or 63 V would be better Marty the 701 is basically a Savannah Classic. The battery I think from memory from them is behind the pilot seat. The fuel sump is behind the pax seat. The last thing you want is a battery on the engine side of the firewall where its is bloody hot. I think you will need the heavier style battery as the Classic and the 701 do tend to be a little tail heavy
  23. Steve It certainly did...It made me very gunshy. I was a low time pilot then and it is indeliby imprinted into my brain. I am so aware of it now when winds are more than about 15kts. We dont really have too much of a issue for DA where I fly but even a small altitude can make a difference in your aircrafts perfomance. I picked up a mate from a airfield west of here to go to a breakfast and it is about 2000ft AMSL so nothing you would usually worry about. But when we finally got back there to drop him off the temperature of the day had gone from about 20degC when I picked him up to about 40degC when I was landing back at his airfield....I had my aircraft drop from about 1mtr above the runway...it was an arrival...not a landing. The extra weight of the pax and the extra fuel I had on board I was probably at about 560kg. The aircraft performance was drasticaly degraded. It sort of shocked me a bit because we never usually see that as most places I fly are around sea level. So I can imagine the huge differences when these guys overseas are landing at 7 and 10 thousand feet.
  24. When I was trying to bet my 25hrs up on "The Girlfriend" after building her I could only go 25nm for those 25hrs. So I used to do Caboolture to Kilcoy to Caloundra in various different formats. One day it was about a 20kt south westerly and I was about 2500 ft on the leaward side of Mt Tibrogargun which is only about 1200 ft high I think..if that...I was about 5nm to the NE of the mountain and I got the shock of my life..the girlfriend was tossed around like a feather and went to 90deg several times..luckily I was under the max rough air speed of 74 kts...it frightened the crap out of me...that was rotors off the mountain and rising double bounces as it was a lot higher than the mountain so it may have been the second hop...all I know is now I am very aware of lea sides of anything on windy days...learnt my lesson hard and fast...same as my first real experience with DA...learnt that pretty quick as well...we dont have that where I normally fly but I was away for this one and the airport was a lot higher than I normally fly in but it was a stinking hot day ..thats what made the difference
  25. Yes I heard about that incident back then. making carbon props for any direct drive engine has been a learning curve for all the prop manufacturers. Eprop are very anal about making sure the product is perfect when released and this is why it has taken a while to get their Jab version completed. they do huge amounts of testing to make sure. They have been testing their designs now for quite a while and it has taken a long time but you can bet when its done it will out perform any other 2 blade for Jabs on the market
