Hi Derrick. Do you have good water pressure by all radiators, do you have a big powered water pump there? I think, better solution for you would be to move main radiator back, nearer to prop. You have more than 20cm there. I estimate about 30cm... Your exhaust could by interfere there, but your prop would better sucks the wind through radiator. Hmmm, you could put it after the exhaust pipe... Sorry, my minds only... :)) I had a trouble with oil cooler, then I made some different solutions. Like yours.
Jozinko, yes the water pump handles the water flow just fine, however when I broke in the engine the water wouldn't go past 136!!! After it is flown for the first time, I'll decide if I need to install some sort of water valve so that I can control the water in flight. I sure want to say thanks everyone for the great comments I've been reading. Yes the helmets and headsets are the American Flag too!!!! I still have to wait 3 more weeks for the FAA to come to the house to certify it.
Happy Triker, I picked up trike the first week in August, however they sent me the wrong wing, the engine didn't come with a gear box so they had to send me one, the color of the trike was wrong should I go on? There was no inventory sheet, or instructions. The info I printed off of the web site was not correct so I received some stuff that I needed and some stuff that I didn't. Until they work out the bugs I would suggest not to buy a kit. It did save me about 10 grand though. Anyway it was completed in mid February. I also work 6 days a week so that was a factor in how long it took me to put together.
Hi Derrick, it seems that is the continuas issue with them. They don't have any parts number system and many of us have the same problem of recieving wrong parts all the time. See you at Pahrump !! Henry
I added an extra oil cooler to my 912 as the temps would get too high in the summer. During the winter I just cover the extra cooler to keep air from flowing over it and the temps are normal. I fly in the desert of St. George Ut. and it gets really hot in the summer.
Hey Jozinko, I found a company that makes 12 volt DC operated water control valves 5/8" and 3/4" that I can install into the radiator hose comong down from the top of the engine where it splits in two, one for the left side radiator and one for the right side radiator. The valve can come one of two ways. Power off open or power off closed. Depending how she acks in the air, if I need to warm up the water, I can install just one valve on either side, power off open, hit the switch and close one side which would allow water to continually flow while I warm up the engine. It uses .7 amps when powered on. What do you think?
Bill According to CPS Rotax doesn't make a different thermostat, they suggested if I wan't to use a different one to try and match one up to a car. Don;t think I'll do that.
I think bill might have been suggesting a second inline thermostat in the radiator line. Lockwood aviation gave me one that works on my oil system, probably the same ....
Wow. Makes me wonder why not simply fo with rotax brand radiators that mount on top of 582. I have those and they keep my engine more than cool enough. In temps 90F I run about 160 and usually need a few strips of DT to cover the rad if temps are below 30F. I must be missing something here.
In theory, the 582 built in thermostat should regulate the head coolant temps to (135F = start to open), (160F ish = full open). That is not what I'm seeing though. I'm seeing start to open at 100F. I installed a 3 rad system and now I'm WAY too cool. Sounds like our 582 thermostats are not regulating at the proper specs. That may be why we are seeing different results with 3 rad systems across different trikes. My instructor has a 3 rad system and his does fine, no tape needed. On the same day mine needs all kinds of regulation taping. Frustrating.
Every one thermostat have different open temperature. It can be different about 20°C. Im car parts seller, I know it. You must to find one where is open with temp what do you need.
Hi Joz. Sounds like you agree that the same model numbers will open with very different temps. I guess the recomdation is to order another thermostat and see if that one regulates the temps better. I'll jump on CPS and see what the damge is.
No, the same model number has still same open temp. You must to ask for higher or lower temp. The model number can be different about a number or a letter, what specifies the open temp. For example 8620 24582 is thermostat for Chevrolet Trans Sport and its open at 82°C. Nex thermostat is still for the same car and it has number 8620 24591 - its open at 91°C. I dont know Rotaxes thermostat. It will be a big problem to use ordinary car thermostat? If not (and Im sure that not) you can to go to visit nearest car spare parts shop and to buy it. If a clever shopasistant will be there, then he advise some solutions. A thermostat is very easy to use to your water circuit.

Cool, she even has a prop spinner! When is the maiden flight?
Hi Derrick, how long did you take to complete it ?
Did a FAA inspector come to check it for the airworthiness certificate ?
I'm just curious.

Why not use a thermostat?
it will do it automatically and you won't have added a complicaction to the piloting thing.

Correct Ken.
i think the motor would be much happier with automatic regulation keeping it just right, rather than, on again/off again heating and cooling.
Something like this: http://www.ebay.com/itm/Meziere-Enterprises-WN0071-Inline-Thermostat-Housing-For-1-1-4-Hose-/221662062649
should be fine, even if you had to get it modified for correct hose size.
