My Posts This: Topic Forum | Buddha, I did many versions of this frame about 10 variations that included the area you are concerned about, and what it boiled down to is not just weight, but the amount of machining, and material used, the machinist was able to use that area of carbon from the sheet to make the battery tray. I cant really agree with Clive more on this in that yeah we can spend a lot of effort trying to make the frame bullet proof, but no matter what, something is going to break, Ive crashed about 3 sets of CF frames and some where stronger than others, the stronger ones in very bad cases transferred their damage to other parts like the the lipos, and I had one case where the frame survived, but it tweaked the boom mounts enough to crush the Gyro case. A GY401 is far more expensive than these frames. In the cases where the frame was weaker, I ended up bending some cap bolts because the shear from impact was absorbed by the bolts giving way. I think that strengthening that area would only protect in from a full on nose in the tarmac crash, and I think alot of you would agree that that type of crash usually involves a major loss of everything on board.
i think youre correct in that some reinforcement in that area could be beneficial, but since the machinist has to use another area of the sheet or another sheet altogether to make the other parts, the cost is going to go up. |
