Default RE: 3W85xi First Look

Well she finally flew today... I got 4 flights on her and then came across a rudder linkage issue which grounded me. Flights were short and sweet ranging from 10-12 mins with the first one being about 8 while I worked off the first flight gitters and got the madian out of the way

Intial impressions I was a little bummed about the top end numbers. Transition was extremely good and you can tell she is full of torque but the intial number was 5600 peak on the Xoar 27x10. Clearly a bit too much prop for it. However I didn't have a 26x10 to try so I thought I was just fly her and see how it did.

The plane came in at 24.28 pounds without my ignition battery in it.. 3W wants a 6v pack in there and I didnt have one with me at my buddies place to add with the scale.

Anyhow.. the field was packed and a bit windy so I figured I would put some flights on the plane and get it dialed in a bit while I got used to how it flew.


On the 2nd flight I noticed an audiable increase in pitch at full throttle... it appeared the engine was already starting to wake up. I was running Lawnboy 32:1 with 93 oct. gas (3W calls for high octane). For the 3rd flight I had to tweak the needles because the low-end was noticeably rich. As I retweked the motor and tach'd it my ears were correct.. she was peaking at 6050 and I backed it down to fly it at around 5880.

It def. has a nice smooth idle / transition and hauls around the 260 with authority. Hovering has plenty of pullout and verticle lines are effortless it def. doesnt loose any speed and a couple of times I let her climb exremely high.

Unfortunately no video today.. I wanted to get the plane dialed in a bit better. I had planned to film the 5th flight until I noticed my rudder linkage had a bunch of play in it. I had noticed trying a KE loop that I had lost all my rudder power and found the problem.


Needless to say overall the engine is doing quite well.. I will have a 26x10 asap. The guy who does video for me is meeting me Wed so I wll get some then for sure.
