Well it finally happened. The carb on my 3D+ came loose on the second flight, and went lean in flight which resulted in ruining the piston! So this time, I’ll order a new piston and ring, buy all new loctite [red and blue], and silicon gasket sealer. I will rebuild it and try it again, and if that doesn’t work…I’ll buy a new motor.

So far the parts ordered for the Thunder Tiger motor comes to $65.99 [piston, ring, connecting rod (just in case)]. I also ordered a piston, ring, and...

The start of the three day weekend…Saturday was a mixed weather day, cool and rainy in the morning, windy and warm early afternoon, cooler and calm early evening, then back to windy…35+ mph! I Managed to get out flying Sunday after church, and only one flight yesterday…too windy again!

I worked with Greg for a good portion of Sunday, hover practice. And we did make some progress after his training gear started failing! Greg bought this 5 legged, cone type training gear for learning...

Yesterday was a beautiful day for flying! I had two heli’s to test out and not a lot of time to do it in. I started with the Trex 700 first. Within 5, or so, minutes I blew up the Align motor. Prior to this flight, I had changed all the fuel tubing, moved the header tank lower and stuck it to the side of the main tank. I opened the needles to two turns out and started tuning the motor. Everything was going great, nice smoke trail, had some power, but still on the rich side. Then I decided to perform...

As of Friday, last week, my work hours changed, so now I can fly in the mornings! Took my Trex 700 and the Compass 3D+ out early in the morning Friday. I started with the Trex 700 to tweak the Align motor I installed. A few adjustments and it was off and flying! I was having some rich/lean problems and wasn't able to track it down. For the most part, the motor was on the rich side. So I started practicing some new maneuvers.

On the On the third flight, I noticed something odd. The...

Short update...

Finally dug into my Trex 700... Upon removing the muffler, there was a bunch of oil sitting in the exhaust port. Then when I removed the back plate, more oil poured out…not fuel, but oil from the fuel. There was about an ounce total just sitting in this motor. The motor was running way rich.

Ok, no problem…cleaned it up and swapped motors with my Rave. At the time, the YS 91 3D motor was in the Trex 700 and the Align/O.S. 90 was in the Rave. Now the...
