Sure, you can't use those fancy self-tightening props but - do you WANT to? I have seen those unscrew themselves after stopping the motors after landing

Nowadays I buy simple and plain props and screw them on using simple and plain nuts or prop adapters and just check every once in a while whether it is still securely fastened.

I have a Phantom 2, and I do have to say that I don't worry about the props falling off due to the threads and all that.

But I'm new to building, so the reverse threads are what I'm used to. The first time I got the props spinning on my scratch built, a nut flew across the room because it got loose. Since then I got lock nuts, but, and this is just me, I feel safer knowing that my props won't fall off.

I have plain old props on my build (HQ 11x4.5's), and I now secure them pretty tight. I also have the bullet nuts, and I slide an Allen wrench in the holes to tighten them.

I am still nervous when I fly my build, so I'm not going to get too crazy or go too high all at once, just because I have a Phantom. So that will give me time to see how the props are. And I'll keep the socket wrench handy as well to just check them periodically.

Made some changes to my Crossfire build this week. Change the legs to move them off the arms, makes it look a little funkier. I also HAD an ImmersionRC 600 for FPV, but wrecked the antenna connection, so I bought a RMRC Cricket 600mW Tx, works well so far. The FPV video was in black & white, which it was after I wrecked the Immersion, so I ordered a new camera. The Cricket is pretty solid, and very small.

I took it out for a test flight last week, and just as I was landing, it flipped. I thought I had a bad motor, so I ordered a new one. Motor sputtered like crazy, so I ordered a new ESC, WITHOUT checking solder connections. Come to find out 2 of the connectors on the motor side of the ESC went bad, so I resoldered and it works good now. Going to keep the new ESC as a spare.

Will hopefully be able to fly it next week, supposed to be in the teens or lower until Tuesday...

Link to the crash video, not too dramatic...

Those are some healthy motors you have there. 800kv?

You could do 4S and 1045's I would guess.

SunnySky 2216-12 800kV. They sound WAY different than the motors I'm used to on my Phantom... lol... They make the quad shake a little when they power up.

No worries... having so much fun learning about how all this stuff works. And also reading this forum seeing all of the other builds. I think I'm finally at the end of the build, just tweaking some things, maybe trying to get my GoPro lower to get the props out of the video... but electronics-wise I think I'm all set...

After talking with frame designer he has added some upgrades to the design. The first frame was printed for 6 mm motors and all I had was 8.5's which is what it really needs anyway. I opened up the motor mount holes to 8.5 mm which removed the built in LG. The foam blocks work OK but the EPP takes a set pretty easy and they start falling out. The new design has better cooling and 360 protection at the bottom to protect those delicate motor leads.

I found your video some posts ago. Very cool, the opening mouth. Make it blow some powder and it would be perfect !

Btw, this is my Evinrude.

Here is my FAA exempt 200mm plywood frame. [ 30g ] It needs minor tuning and then it's maiden. Did fly it out in the yard to test video from Runcam HD. No jello! I will post a flight video this weekend. Battery is 1000mah 2s

Great weight! But first minor crash will be the last for this frame

True that, the frame has to be light to stay under 250g. I made a G10 version that is 36g, which will also be under 250g. Not hard to make a 100g frame to stand up to a crash, but then it would not be under 250g.

If the frame only weighs 36g in G10, then a carbon version will be wicked light

Yes I have some CF coming.Just experimenting with different materials to see how lightweight I can make a frame. The whole project is based on under 249 grams so it doesn't have to be registered. You can't have it both ways the frame under 250 is not going to hold up in a crash. This frame is not designed to be a racer,Just a nice little FPV rig.
