Never put a hard prop on a green machine! Ever!
Okay, gather 'round, take a knee, and lend your attention fellow Green Machine pilots, to hear the tale of one sadder but wiser 'early adopter' of a particular mod.
Let me start with the lesson learned, first: NEVER PUT A HARD PROP ON A GREEN MACHINE. EVER. Why? Well, the APC 7x5 prop is a nice prop. It's magnitudes stiffer than the floppy original, it's faster, and it's quieter. So why would the guys at HH not put a harder prop on right from the git-go? I found the tragic answer first hand this morning, and before any of you guys beat up the design guys at HH for designing a 'weak' mount or other prop train parts, I figure it's kind of like trying to drive a blown rail dragster on the highway and getting a side-impact from a regular car, and seeing that impact destroyed your tubular drag frame: certain designs have certain applications, and if we mix and match applications and parts without understanding the consequences, bad things can happen. I already told you guys I had a low altitude incident this morning. I was at zero altitude, relatively low speed, and inverted over grass when I snagged the vertical stab. Of course, it snapped off, and a little glue put that right in no time. And if I had been wearing the flippy-floppy stock prop, I am 100% convinced that would have been the total extent of the damage. Maybe bend the prop, maybe pop the cowling off of it's slide mounts. That floppy prop is there to prevent nose-over or crash damage from being transmitted into the adapter, shaft, motor, and mount! So, instead here is a list of my actual damage: * vertical stab broke off * prop adapter bent * prop shaft bent, at least two places (rotor not running true to stator) * cowling has broken foam at nose area * motor mount broken off two places * cowling tab broken off * foam holding motor mount torn off of front of plane two places * radio pulled loose from mount by throttle signal wires attached to ESC None of that worried me, because I can easily fix it all, EXCEPT the bent motor shaft. If I just had to buy a new adapter, oh well, not too bad. But the shaft is bent in two places beyond just the adapter shaft, and even with all grub screws removed, including from the mount, none of the parts want to slide free. The shaft is held through the aluminum X mount with a tiny "C" clip, so that will have to come off too, and then Im sure I'll be able to press the parts out, but in the end, this is going to be a major headache and some bucks for parts instead of just a minor fix-up with some glue. I also worry about the bearing in the mount, given the forces obviously having been put put on the shaft. I am thinking of just upgrading to one of the motors already discussed in the thread, rather than trying to repair or replace this one. The three arrows in the photo each point to a place in the shaft that is a different angle than the rest of the shaft. |

That's not funny- that is ORIGINAL "QQ"
- for best performance during flight these hinges don't align with elevator--oh dear, what a pain !![]() BUT I'm sure..the next planes in these size will be better...QQ has a "nightmare on Edge street" every night I think so and he will make all better with his next plane

I learned long ago on my gassers, not to go with the stiff prop for the first few flights, as too much damage results in a nose over or bad landing. I change to the intended prop after I have gotten a flight or two in to get a lil more familiar with the model in the air. |

) wasn't zipping along at all. But every bit of the forward energy went into the prop/shaft/motor mount and tore it to heck when the hard prop hit then stuck fast in the turf/ground, and pole-vaulted the plane butt-end over head-end rather than just sliding along on the body parts, once the stock prop bent and released. And this is the second time -- same effect happened in crash #1 which broke the motor mount, but did not bend the shaft. This is an incident which I think could have happened any time -- did not even 'wrong thumb' it, just misjudged my clearance height slightly while over a somewhat bumpy field, on a particularly low pass. |

I'm going to be selling my spare Edge by the end of the week $155 shipped and tested. It's never been flown and is in great cosmetic shape. It just needs a new prop adapter since I stole it for the one I'm flying. I've bent both now landing in grass. It will have a EFL1920 adapter on it with GWS 7035 black prop. So anyone looking to get one or an extra one here is your chance to get first in line. PM me if you want it before I put it on the classifieds.

So my LHS finally got the 540qq in stock ![]() ![]() ![]() Maidened it this afternoon with the stock prop , it was a little warped right out of the box but flew great! As you can see i have now fitted the GWS 7035 prop (the faster orange style) Flipped the nut and re-trimmed the spinner.I checked all the problem area's but still lost the tail wheel on the second flight ![]() To my amazement i found the tail wheel but not the collar, so i glued a small piece of plastic onto the tail wheel shaft to secure the wheel (seems solid) This plane is alot bigger than i thought, guess i'm so used to the umx stuff sbach etc. Only got 3 flights on it but i'm impressed , It lands pretty nice , easier than the sbach 3d i'd say! Had my high rates set to 80% for the maiden, it rolls pretty fast so i don't think i'll need to go any higher for a while I'm now going to re-route the esc to under the battery tray ready for a few flight tomorrow , weather permitting ![]() Cheers |

Still waiting to hear from HH you guys who talk to them how long it take? I contacted Friday when got plane and sent a copy my receipt and all Friday I have heard back from Amain they wanted pics so I just sent them pics. I don't have internet at home right now so Have to check mail when I go library or to my parents. I know they say they don't have servos in stock I am going to see if they will just send me two of the ds35 ones. I know they prolly won't but its worth a try i guess.
they should be close to the stock size and should be better. I am broker then broke right now or i would just order something else. to try Really want to be flying this thing not just looking at it, but today is very wet and suppose to be few days this week but end week should be nice. http://www.horizonhobby.com/products...FQkFnQodEHcAKQ |

I have always had great response when I called Horizon about a problem. Not necessarily so if I e-mailed them though. Call them, be pleasant, not ranting and try to discuss problem and they have always ended up coming through. There has been a time or two that I could see I was getting nowhere with the rep I was speaking to, so just let it end at that and called back later and got a better rep.

My mrs said to me I'm not to buy any more planes
![]() When asked what I want for Christmas I said she should buy me a plane! She agreed ![]() I was getting either one of these or an Sbach 3D. Final answer, this one!! What is a popular battery choice for this? Any suggestions? Tony
