So after reading a ton and Doing ALOT of chores and what not I saved enough to get a dx6i to fly my newly modded SC and while reverseing the elevator in dim light I accidentally reversed the throttle and the plane crashed to the floor  :'(destroying the prop and cutting up the esc and part of the fuselage by pulling the firewall out on itself but luckily a new esc (40p) from hobbywing on amazon was 30$ and a new prop or 2 was about 3$ apiece and I also destroyed the cowl but on a good note I snatched up my beloved wing before I could get touched so I'm currently waiting on a few parts to come. |

I know it's a bit late, but if I'm fiddling with bits on my plane at home, the prop ALWAYS comes off. Not so much what happened to you, as if I accidently knock my TX, and turn the motor on. www.rcgroups.com/forums/showthread.php?t=389442Look at the bottom pic...... There are many similar tales across the 'net. Please remember, this is a hobby with REAL, flying aircraft. Not toys. OOOOh, lookit the likkle airplanes..oooh, aren't they cute! OOPS! My fingers/Arms/Legs/face have been cut off ! (please delete as applicable) I have had to point this out to people in their mid 60's before now, and once to a retired naval aviator! It's NOT a Toy! It can Blind, maim and kill if not treated with the respect it deserves! Propeller is ancient arameic (same as Jesus spoke!) for 'Knife spinning very fast!*' Take heed! (* This might not actually be true.) Anyhoo, lesson learned, cost some $$, no real harm done, your maiden will come!! |

Yup. I took chunks out of a wooden shelf when I was trying to learn to stick program an ESC and ended up reversing the throttle. For those not in the know stick programming usually starts with the stick fully ON, so when I reversed it the throttle was now, FULL throttle.
I'm real glad it wasn't chunks of leg.
Now, planes get tied down, and/or prop removed as appropriate to the task being done.
When I bench test motors I go in an adjoining room and barely peer around the corner. I've had props fly off and they always seem to depart a 10,000 RPM, which gives them the velocity and punch of a small caliber bullet.

I had it facing way from me and I was preparing to go for the maiden so the prop was on. Any who lesson learned ad I will from now keep the plane tied down I also had the wing just placed next to the plane so it didn't take off just rolled off the coffee table

Never disrespect a prop. In 1990 I was flick-starting a 4-stroke engine (OS48 Surpass) on my WOT4 and it kicked back and rapped me on the back of my hand. Ouch! My hand went numb and when I looked down I couldn't believe the amount of blood. Thankfully a fellow flyer at the strip took me to Casualty. My hand needed 5 stitches. 22 years later I still have the scar.
OK, that was an IC engine; we don't flick-start electric motors of course but perhaps because of this it's easy to be blasé about them. They may not be noisy like an IC engine but can still chop a finger off. Never put your hand (or arm, face, pet, etc) anywhere near a prop if the battery is in the plane. And never install the battery with the TX switched off. Switch the TX on first and make sure the throttle stick is at minimum (and that includes the trim). Then place the TX where it won't get knocked.
Respect it like you would a loaded gun and you won't go far wrong.

I have slice on my left wrist ( bear in mind I'm in my 40's now, this happened when I was 24...)
And I STILL get people asking "why did you try to commit suicide?"....
The slice came from trying to adjust the needle valve on an MDS .40 two stroke whilst it was moving. And before anyone asks, yes, mine was upside down, I just didn't know any better at the time..
Which is why I love electric.. all the fiddly bits are at the back ( more or less!)

I learned that nothing can be more disheartening then seeing your blood splattered all over your wall and workbench. I sliced my knuckles real good when my J3 went full throttle, from that day forward, PROP OFF!  |

So after reading a ton and Doing ALOT of chores and what not I saved enough to get a dx6i to fly my newly modded SC and while reverseing the elevator in dim light I accidentally reversed the throttle and the plane crashed to the floor :'(destroying the prop and cutting up the esc and part of the fuselage by pulling the firewall out on itself but luckily a new esc (40p) from hobbywing on amazon was 30$ and a new prop or 2 was about 3$ apiece and I also destroyed the cowl but on a good note I snatched up my beloved wing before I could get touched so I'm currently waiting on a few parts to come. I reckon everyone has done something along those lines. My wake up call was with the skyraider. Fitted an uprated ESC with a higher SBEC amperage on advice from another forumite. Unfortunately the failsafe mode on the new ESC was to fire up the motor at "low power" when it lost its control signal from the Rx. I commited the cardinal sin of switching the Tx off before disconnecting the battery after some fine trimming work. The quilt cover on the spare bed is a little bit more sorry for itself than previously as a result.  Sometimes it seems we newbies will never get to be experienced and go through life without turning large, smooth pieces of plastic into jagged smaller ones. Which brings me onto another thread ........ |
