And still no real world figures from a j230 owner with a CSU prop , all speculation and guess work , which maybe correct but until it’s actually confirmed speculation nonetheless

Still waiting for some one to give real world figures . Actual demonstratable real world numbers from someone who has one on his 230 up until then is all speculation, and then ask the question would you do it again or is it not worth the cost.

I too lust after an air master type CSU for exactly the reasons you want one Skip . Short field opps in my 230. I cannot seem to find anyone who has done this before and I am reluctant to jump to purchase one . At a recent agricultural seminar an instructor suggested that if you want to try out a new product first convince your neighbour to try it to see if it works, same principle applies here

That s a lot of paint Hope you make it down south to show it off

Tenacious little fella .

You should be happy with the rotax do you have a motor or on the hunt for one?

Are you using Subaru motor or rotax

Really getting stuck into it . Good on you

I admire your tenacity and your ability to do the work . I bet the cowl will look fantastic. Keep at it we will just have to Waite to see the fruits of your labour

The Hummel is a fantastic Looking little aircraft. Every thing looks in perfect proportion . I know of one with a 503 rotax but the engine of choice is the 1/2 vw. I wonder if another opposed twin would fit as I have heard the vw has some vibration issues . Park on in my hanger any time you want

I thought at one stage there was a tail wheel version of it

Keep at it you are doing a great job. It will be the best looking one around

You are really getting stuck into it good on you . Looking forward to seeing it fly soon

Good looking aircraft. A local aero club member had on which had not been built with any real care but I could imagine that correctly built it would be very nice indeed . Quite fast and the Subaru engine while not bulletproof, it’s not far from it . He normally cruised around 100 + knots on around 22 phone. Keep at it we are all waiting for the first flight

Looking forward to seeing your progress. Do you have an engine for it? I have several in stores and one engine reconditioned with modified heads and cam . I reconditioned it in anticipation that I may need it for my Avid, but it’s proving to be so reliable that I fear that it will never wear out

I could not have put it better myself

Airports are part of the infrastructure of councils and a cost of doing business. Following the principle of user pays let’s see them charge people for using parks and gardens, foot paths, libraries. Only my opinion

No Flightrite I am not angry, but I am disappointed that so often these discussions deteriorate from what was a reasonable question to just plain waffle about anything . The question was ,I thought plain enough and I would have thought those with FIRST HAND information would have either told me yes it is possible this is what I did ,OR no this is what we have and it’s not possible under the current rules. I thank those of you that did enter the conversation in the spirit it was intended and ask those of you that didn’t to consider the worth of what you said in light of the original question. We seem to be discussing DOGS now so as far as I am concerned this topic is now closed

Yes point taken but when you want specific model type info it clutters the conversation

Sorry gentle men we seem to have drifted away again. It’s Jabiru we are talking about and my original question was to Jabiru engine powered aircraft. I appreciate your well intended comments, I have had one person reply with direct comparisons of Jabiru’s with and without thermostats (thermostasis brand) and I thank him for his input . Jabiru specific actual information or real observations only please

In the auto trade that would be the thermostat . In the jabs system the barbed hose fittings are far smaller than the oil cooler in and outlets. My reasoning is If the capacity of the pump has a higher flow than the hose allows ,restricting the oil flow through the oil cooler and causing a oil dump via the relief valve (in effect this dumped oil is not being cooled) would this raise temps on those hot days climbing. Fitting a thermostat which allows the fitting of larger hoses with larger flow may make the cooling system more efficient ?

Will the larger internal dia of the hoses allow better oil flow more heat loss?

I am well aware that the thermostat controls the minimum temperature and the heat exchanger efficiency controls the maximum . So the question still stands do any Jab drivers have the experience to answer the questions

I have the Thermostasis and will fit it to my 230 . Is it worth going up to the larger hose, to me it makes sense to go larger hose, I am hoping it will keep the oil temp lower on really hot days hence the question

Has any one flying jabiru aircraft or jabiru powered aircraft fitted an oil thermostat and apart from a faster warm up and stable oil temperature, have there been any other noticeable. Did Using larger hoses to and from the oil cooler lower your temperatures during the summer hot weather
