CRX Turbines

Terry is right, there are only two connections. The design is very smart. The pumps are extremely efficient, in fact you can use the same pump from a 300 to run an 80. The circuitry and programming are that fine tuned. On the smaller engines the tubing loop is used to break up bubbles therefore reducing the chance of a flame out. In essence this pump is the equivalent of two parallel pumps because of the internal, multiple gear set up.

I believe he's referring to the fact that the pump face has 4 nipples on it and requires the use of "Y" festo fittings to tie them together to meet the fuel demand of the larger turbines. But for me personally, it's never been even a remote issue.

The pumps works fine on my SW220. My Pilot J10 112" has the SW220 pump all the way in the front and there is a fuel line that is 102" that runs to the turbine all the way back. Spoolup at 2.9seconds and no issues.Hovering, #D, etc - no issues. Loving it!

The pump is awesome, but RC_Man doesn't like the 4 nipples coming off it and the requirement to run Y festo fittings to bring them down to a single inlet/outlet.

I understand his trepidation with the four nipples and festo connections,, but I have 5 of the Swiwin's and never had an issue with the pump. As Bodywerks said the pump is awesome. Plus, it is a genius idea that allows you to use one brushless pump to power any size turbine.

My understanding its running 7000 RPM higher and 5mm shorter than the 220

The 240 I ordered be here next week.

CRX Turbines

The 240 runs 3k higher than the 220. 220 tops out a 115K; the 240 tops out at 118K

Thanks for the info gentlemen. I'm trying to figure out if I should stuff the 300 or the 240 into my 3D jet. If I run the 300 at 240N thrust levels I'm thinking it should last longer. Any ideas?

Didnt see where you said what 3d jet ?? and then I can suggest which one would be the best for your application. terry

CRX Turbines

If you are doing 3D, especially, there is far more stress on any engine when performing 3D maneuvers because there is less free airflow. If the 300 suits your budget and will physically fit the airframe and not present a weight issue, then the larger engine is usually the better route. The 300 in this case will likely be doing less work and should last longer.

That's what I though. Thanks Andy

When mounting a Swiwin 60B, can someone tell me what the Swiwin spec is for the distance from the end of the turbine exhaust cone and the beginning of the thrust tube (not the beginning of the bell but the actual thrust tube)? I have not been able to find it in any online manual. Thanks so much!!

Generally 1" (25mm) is a great all around number to use if unsure.

Hi All,

Just to let you know that the latest issue of RCJI, April/May 2021, contains a full and detailed test of the Swiwin 80B turbine, as far as we are aware this is the first published test of a Swiwin turbine.

Printed back issues can be ordered at www.rcjetinternational.com with digital issues at https://pocketmags.com/radio-control...ional-magazine

Thanks! I will get a copy.

Testing video of the little 80 powerhouse!

Agrav8ed

Are you at a high altitude perchance? I was expecting the pull to be closer to 18lbs but your scale said 13.6lbs. My swiwin 80 pulls like a champ.
Thanks,

Acceleration and deceleration settings... on my sw120b it was 20/20 and felt sluggish. I upped them to 22/22 and much better , but acceleration could be better still. How much I can go upward?

Canadian Man

My Feedback: (1)

Correct! 3200 Feet ASL

CRX Turbines

Ceeray up the Acceleration delay on the ground until the motor begins to sputter, then back it off a click or two. You can adjust this while the engine is running. You do not need to match the values as they are independent of each other. There is no set rule for either setting. We send the engines out at 30/30 but if you are at a higher ASL then you might not get the great response. You can go to a max of 70. Push it until it is gurgling. For decel be careful, because, you will not recover from decel set too high. Also keep in mind that in the air there is much more airflow and the turbine will generally run smooth in the air if you get it right on the ground.

If you get stuck or have questions call us.

I am at 600 feet and on my SW80 I get 16.5 pounds of thrust (73 Newton’s) at 154,000 rpm and 17.5 lbs (78 Newton’s) at 160,000 rpm.

I'd hate to see what my 80n turbine gets at 5500ft not including density lol

heh, like 24 N LOL

ok thanks, mine was set to 20/20, I will raise them up to 30/30 for testing.
