Tonight I am a very very VERY happy bunny!!!
I've just bought myself a BeastX off these here forums and a DFC head of t'Interweb to fit to my Trex 500 GF.
So I figured, if I'm pulling half the heli apart to fit the FBL setup I might as well give auto-rotations a go as I don't have much to lose if I crash.
I've always been able to do them on Phoenix no probs but I've never had the balls to try for real.
So tonight, I hit the flying field. I spent 3 batteries practising - mostly under full power, trying to get the nice blade farts going.
I then started hitting throttle hold and then flicking back out before getting TOO low. A couple of times I hit the ESC slow start but no biggy as by this point I was getting the hang of it so had plenty of inertia in the blades to recover and gain height again while the blades slowly spooled up again.
I started off with a straight line TH pitch curve from 0% to 100% on my DX6i but eventually settled on 20%--20%--50%--75%--100%, that way I can flick TH and dump the collective to the bottom, knowing that I'm getting around 5% negative pitch. This was working well.
So on the fourth and final battery at around 9pm, I decided to go for it.
I got off to a bad start - did my pre flight checks, then flicked my gyro to position 1 (0% gain to centre the rudder servo) but forgot to flick back to position 0... spooled up, took off and started pyro-ing!!!! Landed, flicked the switch back to where it should be and finally took off successfully.
After a couple of dummy runs on full power to settle the nerves, I went for it.... And I nailed it!!! No worries!!! Brill!!!
Over the course of this battery I must have managed 10-15 successful autos from very high up (I'm no good at guessing heights - needless to say the heli was VERY small). Some were OK, some were very heavy landings. I'm amazed at how well the heli held up - I was convinced I must have done some damage especially after one less than brilliant attempt where it landed tail first, then tipped sideways and caused the blades to stop instantly!!! Still no damage - you've got to love the old belt drive!!!
Pros and cons to belt drive I guess - land tail first and hopefully no damage - but on the flip side, belt is less efficient so maybe a torque tube auto is cleaner as you have more blade energy so more time???
Anyway, I got my very first attempt and a few others on video on my phone which are now on youtube. It's painfully embarrassing to watch these as I was so excited I was acting like a complete loon!!!!
Unfortunately I didn't get my very last attempt on camera - it was PERFECT!!! Perfect starting height, perfect approach, perfect flair and perfect soft touch down!!!! It was like poetry in motion!!!!! I thought this was definitely a good point to pack up and head home!
Videos below - I'm sure they're very boring to everyone else, but to me they mark a BIG step in my flying. From now on, I'm planning on ending every battery with a high auto
