How do I flatten KBDD Blades?

gunshine · 12-18-2011, 03:10 PM

Second set and these too are warped. I turned the first set into molten plastic. Someone mentioned boiling water and pour over the blades on a flat surface. I did that but they just floated and were still warped after they cooled (I just let them float until the water was lukewarm).

What can I do to get these babies flat?

Perhaps a heavy book on them overnight?

Run them under hot water, or use a hair dryer

Have a Hummer run them over?

You know the curvature is intentional, right?

I did not know that. Which way is the curve supposed to go?

If they're causing the wobbles or shakes, they're out of balance which is a weight issue.

Not what a team pilot or rep for KBDD said in another thread here or on RR or RC Groups, can't remember which one it was. My set was also curved so I searched and found a long thread about it a few weeks ago.

If you are sure about the intentional curving, post your source so we can read and learn please.

Once there rotating at around 4000rpm, they will straiten out.

If it helps I slide the curved blade between my tightly squeezed fingers, the oppsosite way to the curve a couple of times before flying..seems to work

I have had about 5 pairs of KBDD blades, and have seen others. So far, thats more than 10 blades, bought at different times, different colors, with identical curvature. Never seen a set without this curvature. If that isnt intentional, I dont know what is.

Varc · 12-19-2011, 05:46 PM

Besides, arent curves sexy?

Mounted in the grips one curves up and one curves down. I'll take a picture tonight before I try straighten them with hot water, a flat surface and some heavy hardcovers.

Just saw this thread for the first time, 2 hours after I tried matching the CoG and noticed the curve. Thought it happened during shipping or something. Have them under a book right now... With these blades I get random tail kicks, which I believe is caused by excess vibes. Switched back to the stock blades and no tail kicks.

How about a steam roller?

The blades should curve Up, not down

near boiling water for a quick minute

GravityJunkie · 12-23-2011, 08:58 PM

I don't call 10 pair of curved blades intentional. I call it poor materials or process.

I guess the one straight pair I received otta the 3 sets I purchased musta been the defective one...
