Default Swiwin turbine repairs

Anyone had a swiwin turbine repaired? My 60b now smokes like I have a smoke system at low to 70% throttle. It only has 3 hours fun time and is 1month out of the 1 year warranty. I was told that it has an internal fuel leak and the fuel is not burning which causes the smoke (running diesel). Just thought I would see who repaired your turbine and if you were happy with the service.

I don’t think CRX is doing anything anymore.
contact Andy Davis at www.rcjetwerx.com.
He does not do repairs but is a dealer and will be able to point you in the right direction.

I had an email from Andy a couple of weeks ago and I got the impression he is doing repairs to engines he sells.

I talked to Terry at swiwinturbines.com. He said that people had some problems running Diesel fuel and to try Kerosene or Jet A. From day 1 I had had idle problems where the idle would go down as far as 39000 rpm when it should be at 50,000. I ran some Kerosene today and not only did the smoke problem go away the Idle problem did as well. It now holds a reliable 50,000 rpm. It's good to know that my turbine is just fine but just does not like the diesel.

BTW

My SW 60 runs fine with diesel and no smoking up the block either.

I had to have a fully charged 3s motor battery that kept voltage around 12 volts and it ran and restarted etc with diesel just fine.

It may be that the quality of the diesel is not the same in all places. Mine ran ok for about 15 tanks but I did have to set the minimum rpm to 3600 or it would shut down from going below minimum setting. After 15 tanks it started smoking when below 3/4 throttle and even looked like I had a smoke system when in the air. I switched to kerosene with 5% oil and have about 12 flights and it runs great and no smoke at all.

Diesel absolutely varies from region to region. It tends to run hotter. I have gotten periodic calls about this and I have come to the conclusion that each situation needs to be looked at on a case by case. If anyone is having issues, I can take a look at your configuration and offer some input. Please make a note of the firmware revision in the "other" menu as configuration parameters may differ between firmware levels.

For anyone having running issues they believe related to fuel type, I generally start with a look at pump start voltage. This a balancing act. It is a good idea to put the motor in a test stand versus running it in a plane. It can be difficult to figure out the right config without worrying about burning the tail feathers of your plane. Remove the fuel line and initiate a start, then observe the flow of fuel. You want nothing more than a drip… drip… drip every second or so. The voltage is not a set value. It depends on the actual pump. The magic value might be .4 or maybe .5 or maybe .34. The degree of change is in .02 volt increments. Be patient.

Next thing to adjust if needed is the percentage ramp. If you have a motor that is ramping too quick with fire out the tail, I back the % ramp to 60 right off the bat. 60% will give a much longer and milder start.

Ramp Start – Back this down to 1 if needed. This controls the step value when the ecu increases flow to the pump.

Gas Valve – This controls the flow to the plug at start. You can lower this to 15 if needed but this might cause long preheat times. Raising this will increase fuel to the plug and thus lower the time needed to preheat the engine. Once the engine reaches 120 degrees the engine goes to fuel ramp. My suggestion when making any adjustments, make a single adjustment and test then make another and test. Always write down the values before you start or take pics so you have a reference to go back to if needed.

If needed contact me directly.
