250 repair under way!

I finally got around to taking apart my Trex 250 for repair. So far I've found a bent main shaft, broken spindle bolt, broken blade tip, and broken ball cup. Not too bad considering. Time to order some parts!

Goblin 380 ready!

I finished the 380 head and tail setup Monday night, 11/9/15!  I'm getting faster at using my Soko Gauge and app also :)

I plan to do some test flights Sunday afternoon at Hoyt park.

Goblin 380 repair completed!

I managed to finish the repair of my Goblin 380, which I crashed about about 3 months ago.  Next up is completing the head and tail setup and I'll be ready to starting tuning the Vbar Neo all over again.  Lol!

Dang it!

I crashed my 250 on my 2nd session with my new Zeal 210mm blades :(. While doing a nose in turn I lost orientation and crashed.  This has been happening a lot lately :(. I really need more practice and need to try and save it instead of giving up and flipping the hold switch. 


This happened at SEFSD on Sunday 10/25/15. And for a change there were more helis than quads this time!  Woohoo!  

Ming's friend Richard's helis.

Hoyt Park, Tuesday 10/20/15

I wanted to try and flip my mCpx, but it bogged so much it dropped like a rock, and I crashed, breaking a ball link on the swash plate.  Once I get that replaced, I'll try again, but higher up!  LOL!


The 250 was flying well enough that I tried doing some flips with it. I need to put in more negative pitch and the tail wagged some during the flip. I turned down the tail gain and it's been getting better. 

I'm heading back out to Hoyt again after work to test the 250 and 450.

Hoyt park session, not!

I tried to get a few flights in at Hoyt Saturday morning 10/17/15, on my way to the track, but it looked like someone was there cleaning trash from the field?  So I decided to head straight to SDRC instead and fly in the parking lot there, before the track opened. 

The 250 flew well and I was able to fly smooth figure 8's, which I was having trouble doing at Hoyt. The headspeed still felt slow though, as it was less than a rocket doing full pitch climb outs. 

I decided to turn off my governor and use a flat 100% throttle curve instead. While doing this will achieve higher headspeed, the headspeed will decrease during the flight and may bog more often.  I'll need to gear up to get the headspeed I want with the governor. The only problem is figuring out how to get the glued on pinion gear off. 

At 100% throttle, the 250 felt much better!  Nice pop on full pitch climbs but with a slight bog. It was also a rocket for about the 1 minute of the flight, until the battery voltage leveled off. I'll need to take some headspeed measurements to find out what the headspeed actually is.

Trex 250 and 450 test session

I rushed out to Hoyt to get some flights in on the 250 and 450. I still need to get used to flying the 250 (feels like the headspeed is too slow) and test the Brain on the 450 (need to tune the flight banks, expo, and tail gain). 

Charging packs when I arrived. About 15 min to charge the 250 packs at 3C and 25 min for the 450 packs at 2C. I changed a setting for the 450 packs program which will hopefully decrease the charge time. 

The 450 ready to fly!

With the clouds coming in and blocking the sun, it got too dark to fly about 20 minutes before sunset.  There's only about an hour of usable light left now after I'm able to get to the field :(
