    Yes Nev the block, crank and cam have all be crack tested including all in the gearbox The crank has been welded to take the extra hp, the cam has been totally reground to ensire corrent profile so that the lifters rotate and the gearbox is exactly the same that is used on the 914 engine so it will take the power. The lifters not rotating has been a issue for the Rotax and this has been the source of cam failures in Rotax, The big thing for the gearbox is the weight of the prop and extension and spinner. Mine is only 2.4kg total and extremely balanced so gearbox load and wear will only be by the physical hp applied to it. The main bearings in the gearbox are now SKF and not Fagg the SKF is a better bearing

    on rebuilds for Rotax at TT then you are supposed to change the valves and of course springs etc. The biggest issue with any Rotax rebuild is the block and the journals. A mate went through 3 engines before he found a good one to rebuild. There are a lot of blocks out there that you dont know until you strip them what lies beneath. So if you buy a engine you do so on the proviso that when it is pulled apart that it is able to be rebuilt otherwise you get stuck with a 5K or 6k ornament

    I dont believe you can in RAAA

    My engine for the S-21 is a 2015 2000hr ex flying school engine. It cost me 5k to buy My pistons and cylinders are brand new in the guise of a big bore kit The engine totally disassembled and measured to make sure all is still within spec and no fretting of the cases. The crank has been welded and all rotating moving parts have been balanced All new inlet and exhaust valves and springs and collets the heads are original but have been cleaned and speced All new through bolts and studs All seals and Oring's and bearings replaced New sprag clutch The gearbox has new bearings and seals and has been retorqued to spec All new oil and water pipes and fuel pump as in the 5 year replacement Most of the major parts are after market but some just can not be bought that way Total cost to me is around 13k others will be much higher Total cost if using genuine Rotax parts would be around 25-27k..new engine being about 34k now This will give me 114hp as stock power, with a tricked tuned exhaust I am hoping to get close to 120hp

    It will depend on the smallest ICE that can power the generator to keep the batteries charged. I am not sure on how much horsepower size engine would be required. Generators now can be at a lot higher speed so you could get more efficency then hopefuly the weight penalty could be minimal. If you could extend flight range to say 3 or 4 hrs plus reserve that would be ok for our market.

    Certainly as a interim that would be a good solve

    Back in those days politicans had visions...now their only vision is how to stay in government not what is best for the country and its peoples. Even though Gough was a raving commie although not a full marxist commie he had the vison to take the country forward but never got a chance to make it possible

    The future is electric of course...but the biggest stumbling block has not been solved enough yet...The batteries or for a more rounded solver...the fuel source

    The cost of the Rotax parts is a big part of what makes aircraft costs being expensive. Let alone the labour costs which are high of course. Most of the genuine parts costs are just off the planet when they are just repacked parts off the shelf from Joe Bloggs auto store
  10. Kyle Communications
    I agree Nev...all the parts we have used are either what Rotax actually use from a manufacturer but we got them from the source. The sprag clutch is from a BMW bike, Bearings are SKF or Fagg Orings and seals are all high end quaility most likely better than Rotax ones but being obtained from reasonable sources the cost is far far cheaper
  11. Kyle Communications
    Yes. My engine for the S-21 only has parts in it that I could not get from elsewhere. I had to get the slippers, valve springs and cotters, studs and various shims and thrust washers...this totalled $2500 !!!! The rest like roller bearings and gearbox bearings and all seals and Orings, the valves and pistons and cylinders were from the big bore kit all have been obtained from elsewhere and mostly are even higher quality that supplied by Rotax Engine rebuilds can be done at a far better reasonable price if you know where to find stuff. I have a mate who is in a business that deals with all sorts of mechanical stuff and is a whiz at sourcing all this stuff. Oc course you cant do this with anything certified but for experimental or 19 rego its not a issue and you literally can save 10k on a rebuild

    I got a new sprag clutch plate out of England for $140 landed here...the only issue is the outer is produced by Rotax so thats a issue but iy is usually the plate and springs not the outer drum that is the issue
  13. Kyle Communications
    We have just got in a new pump we are looking at using as a replacement. It is a Pierburg one...looks like it will be perfect. out of England...40 euro
  14. Kyle Communications
    All Rotax parts are outrageous in cost Each slipper half shell is $100.00 each the fuel pump is $400. Sprag clutch is almost $1000 the CDI are $1650 each
  15. Kyle Communications
    Well if you dont do it you are a candidate to be a statistic for sure. Fuel hose is notorious for breaking down with age and heat as KG says. In the scheme of things it is cheap to do if you buy all good quality hoses from elsewhere that Rotax. There is plenty of parts that are far better than what Rotax supply. Now you must also replace the fuel pump every 5 years. I didnt think it was that necessary until my mate has had his fail. Luckily he caught it before any drama by always monitoring his engine parameters while flying.

    F10 its not that simple at all. I am on the committee at YCAB and there are so many hoops to jump through. Not just the enviromental and safety also council lease agreements and covenants. Then there are the rules from the fuel suppliers and the different structures they require depending on what sort of service you want. I thought it would have been a relatively simple task but it is not.
  17. Kyle Communications
    The yanks have been using some blue coloured epoxy made ones..weem to be good so far but about the same price as the rotax ones I think
  18. Kyle Communications
    Its easy to do because you are not controlling the carbs with flexible bowden cables...both carbs are locked together...the throttle levers on both sides are not symetrical either the distance of the pivots are a half a hole out when using this. Its all done of course in the design but this is also a trap..both carbs are not synced properly even from the factory There is a slight difference due to the offset. We compensate for that with this solid bar sysem

    Ah but with my new throttle mod...no more need for carb balances..well rarely..it will just be for a check...the sinking float saga welll i think thats a thing of the past now
  21. Kyle Communications
    easy done on a Rotax
  22. Kyle Communications
    We are working on getting Mogas at Caboolture. Its not a easy task with all the hoops you have to jump through. The Avgas has been in for a really long time

    The main fuel feed on a Sav comes out under the fuselage then through a tap on the floor then it goes out a 10mm alu pipe under the front floor and the metal pipe does almost right angle curve then direct up the firewall and mine then went to a gascolator. I found it by checking the gravity flow from the tanks to the gascolator and kept sectioning until of course the last piece of pipe was the one curved around the firewall from under the aircraft. I took that piece of pipe out and blew the compressor through it and out popped this bit of white plastic about 8mm x 12mm and it had got caught in the curved area and half blocked off the pipe...took a while to find

    That sympton is a fuel blockage...how do I know?...it happened to my aircraft. A small sliver of plastic came off the inside wall of the plastic tanks and jammed itself into the metal feed pipe to the gascolator and restricted the flow to the carbs. At full power you had about 3 mins until the carbs drained then the engine carried on like a pork chop. reducing the throttle to around 4000 rpm the engine ran fine. Took a while to find the issue. Who would have thought a small piece of tank plastic would have actually came away from a rotomolded tank

    Great letter but the problem is of course it is to a politician and we all know stuff like that just slides off their back like a runny sh$t. The current minister is hopeless as well...Mccormak is just as useless. There will not be any changes that actually make a difference in CASA until the minister responsible actually takes a interest.
