Great news. The slop is virtually gone!

The tip about the heat shrink was very helpful. I wrapped CA'ed thread around the pushrod under the servo arm, and it doesn't budge.

I did a glide test with a 2200mah battery pack (AUW: 19oz), and it has about a 5:1 glide ratio (with large amounts of upward elevon deflection). I think this bird will actually fly, despite the best efforts of its builder.

I plan to use 1300mah batteries when my hobbypartz.com order arrives, and I suspect the AUW will be exactly 16oz.

Thanks for all the help, and thanks for the great design and helpful support Lee!

Most common combat damage?

In regard to the Assassin, what is the most common damage resulting from full-contact combat?

- broken props
- broken motors (fried, bend shafts)
- bent motor mounts
- cut electronic wires
- damaged linkages
- damaged batteries
- torn elevons
- etc, etc

Does damage usually occur from strikes or from hitting the ground?

My vote for the most common damage is broken props.

I would have to agree, they are so vulnerable to a hit, with planes or the ground.

If you are using a prop saver the most common problem is losing the prop.
Then broken props, bent control rods, broken horns (servo and elevon), then the rest occur, but not super often. Damaged batteries are a lot less common now that we bury the batteries the way we do. Another real common damage is prop slashes in the plane just about anywhere. They do occ damage wiring or electronics, but again not too often.
If your plane is a bit tail heavy or has large throws it's easy to stall it and go into the ground. That can certainly cause damage, but most of the damage is just an accumulation of small injuries that eventually need to be fixed.

Speaking of damage, broken props and such, how do you guys keep the small ring adapter thing for the prop from coming out? With the extra props I bought from plane insane that small peice has nothing to keep it secure and I've lost a few of them. Even with a dab of CA my son's came out in combat.

file a flat area on the motor shaft for the set screw to fit in. Then use blue locktite on the set screw.

Mike:
If you are speaking of the plastic prop adapter sizing ring, a very small dab of epoxy should do it...if CA does not.

Lee, would you agree that my motor angle in this screen shot of todays video, has too much down thrust? Just looking for a second opinion. It was not flying well today. Could have been the wind, combined with the key cam taped to the left wing tip.

I will spare the video, there is not much to see, i couldnt keep it steady enough in the wind to get any good video.

Thanks in advance.
Pat.

Hey guys, I have an off topic question, but I really need an answer and since you helped me out before I thought i would give it a go.

I have some 5 gram servos from hobbypartz, and I have them for the basic 4 channels. I am using them in a sail plane I made and when I put a receiver battery in (that runs off of 4 AA batteries) and they work flawlessly. But when I use a 2c 800mah Lipo the servos have this HORRIBLE twitch that is unflyable with. The lipo is brand new. I am using all this with an ar500 and dx6i. I would love to know what is happening.

I do have one theory, the servos are rated to 7.2v and the battery is 7.4v, could this be the problem? Thanks so much for the help.

Fishon, a fully charged 2s lipo is actually supposed to be 8.4v but I'm not familiar with that set up that you mentioned.

Kind of confusing statement. 4 standard aa batteries is only 6 volts correct??
