do the frames break in almost every crash? i don't remember ever having a frame break on any of my crashes when i use to fly.... blade 400, gaui 200, trex 250, trex 450. I think the trex 450 is the only one i didn't crash though lol
only one i don't regret getting rid of is the trex 250. but got laid off and needed the money. |

Don't attach the skids with skrews, use the cable tie trick (8 ties in total). Prevents the frame tabs from snapping off...
Frame stiffener is a must for several reasons!

No they don't break every time. I broke mine on the first crash and added a lynx plate to both of my 300s. One has crashed "many" times due to motor cut out trouble that will never be resoved and the frame never broke. One of those was over a 100' drop. LOL!

Same here! Had my first crash with mine on Saturday and my frame broke as well. I'm with ya, almost a full rebuild now. My crash was pretty hard though. And I was surprised how affordable the 300x is to repair. Blades and blade grips were fine. My crash is only about $40 to repair. Same crash on my 450 3D would have been $100 or more easy. I think I'm going to mount the AR7200BX on top of the frame when I put the new frame on. That way it's less sensitive to vibes and easier to see the status lights.
SHYGUY: Whats the cable tie trick?

I had a mild crash with mine as I was landing when a wind gust hit me from the side, but I was lucky enough to be close to the ground and only broke the main shaft and bent the feathering shaft and broke some teeth off the main gear also. It also stripped a gear in my Ale servo. But got it fixed back and as I fixed her I put the Lynx frame stiffener on it.......very nice stiffener by the way. I got to get one for my other 300 now. Hope you get them going again soon !

Thanks all.
Just spoke with HH. They are sending a frame and admitted the 300x frame is weak. I just ordered a frame brace from Helidirect. I am considering your advise to relocate the beastx to the top; because I could not go into stunt mold due to vibriations. This rebuild will make me look good or bad. Time will tell. |

I think they (HH/Blade) just decided to put it inside the frame because the gyro mount they molded on the tail block is a little small and it would be kind of awkward to mount it up there with their big foam pad thingy. Use the strong gray 3M tape and you're good to go.

Re: FYI
I also recommend the loctite mod while the motor is out. I have a box dedicated to feathering spindles because I replace them after every crash but I don't think any of them are actually bent.

And once you get enough of them you could form them into a tiny windchime.

I take old main/feathering shafts to work and check their runout on either the lathe or Bridgeport...grab 'em with a small collet and put a dial indicator on the far end. Have yet to bend a main shaft but feathering shafts die easily.
You could probably do the same thing with a thick piece of glass, give it a roll and you'll be surprised at how easy it is to see even a minimal bend. For shafts that are cross-drilled you'll have to chamfer the hole edges first. |

FYI
+1 on bx relocating! I did this to mine after a full rebuild (hit the side of my brick house)
Frame basically grenaded (still never found all the pieces) just take your time and triple check all the frame screws to make sure you didn't miss any. I had forgot just 1 and the bird shook like crazy. It's a learning process for sure... Good luck!

lol, one of the worst vibration issues I ever had was when I left a screw out of the landing gear. With the heli spinning up, you didnt spot it because the weight of the bird kept it down, but once you got light on the skids and lifted off, it got bad quick. That one took me a bit to track down
Crashed mine once, lost orientation in the sun on around my 5th flight. Landed on its side int he grass from about 20 feet up after i got scared and hit TH. Main blades, feathering shaft, one blade grip, replaced mainshaft for good measure. Frame came out ok without brace, have since added one Been over a 100 flights since ok.....this is the one that gets the scorpion and lite ice 50 in a week or so.

Thanks all. I have finished the rebuild and back in the sky. I relocated the beastx to the top and love it. Be sure to check setup f, m and n. I did not check N and nearly put it in the PINE TREES. I am currently having issues getting both blades pitched to 12 degrees. I have swashplate level. Sorry other threads have address this; so I am out. Thanks all again. Fly safe.
DRIVE MUSTANGS HARD AND FLY HARD! PEACE. |
