How about the prop [is it on backwards]?? I know, I know. Any dumb, dumb
knows how to mount a prop. BUT; this sounds about like my first few flight attempts.
launch, and she would down thrust into the ground.
yep. had the prop on backwards. Put the plane on your bench. stand in front of her
get ready, hit the power. if she tries to run over you, your prop is on correct. if not.better do more prop check.

By the way welcome to the thread.
Hello,

I just did the 1st choice. Result : much more noise and , seems to me, less thrust, is it normal ?

What'd you bore it out with? 17/64 drill bit is the one but, gotta be DEAD CENTER. Then, prop balanced, or re-balanced if it already was.

Lastly, (less thrust)....got it on backwards?

Oh, and....no such thing as a pusher prop on a brushless motor (presumig that's what you've got); motor direction is reversible.
(Page 1 is highly recommended reading - maybe you didn't see the sign on the door? It's our motto in fact. A must. De riguer. Or they'll boot you off the island. Well, not me, per se....but watch out for that 'G' guy.)

Eager to hear (see pix, maybe??) about the motor alignment. That's only possibility I see.

Uh....on 2d thought. When you swapped out the nose washers, you din't by any chance replace 'em with a boat anchor or anything like that didja? *LOLOL*
That's a definite "EN SLASH ARR" = = = NOT RECOMMENDED!!!

ADDENDUM: WOAH, STOP THE PRESSES! Prop on backwards???
Motor should be turning clockwise when viewed from rear of plane (least, mine does)
Ok looked at plane looks in alingment to me ( I don't have the good photo equipment or the skill most seem to have on this thread but here is a try )Looks kile it did & motor turns clockwise.

Hope it comes through

Hi Jer,
Your motor angle looks fine.
In all the excitement of the maiden, did anyone check to see if the elevator servo was reversed on the TX?
Remember, back of the elevator goes up when you pull the stick back.

Well dang. hmmmm....
Hey, you got any way of measuring how much thrust you're getting?
Got a gram scale? Any kind you can set on the floor, we'll make do.
Put the plane straight up & down with its nose on the scale & zero it, & while lightly holding the fuse just in front of tail feathers, have someone run motor up to full throttle long enough for you to read the weight the scale's showing. Fully charged battery. Careful - don't let the prop bite ya!

Tell us that & which battery, I'll run a test & see how they compare.

Thank you again for the response.

Check the elevator servo pot on the plane to make sure it's not bad. Full throttle vibration from the prop can cause the servo pot to do strange things. On my first flight of the SS I launched it at full throttle and it dove straight down. Next attempt it launched normally with a tendency to dip. Four or five flights later it started doing involuntay square loops when the throttle was moved to full. After some head scratching and thinking I tested the plane holding it and saw what was happening. Throttling up to wide open I could see the elevator servo fluttering in the up direction most of the time. Root cause? The servo pot was bad. The fix? I replaced the servos with HXT900s. All has been good since.

Done, now it seems more equilibrated, but still much more noise !!

Sur, but the APC prop can be pusher, the hole in the center is bigger on the front of a pusher prop, smaller on a normal one, it's just for the prop adapter on this engine, otherwise my other prop saver could do the job, but I wasnt able to remove the original prop saver.

I just finished reading the whole page and related links. But one thing I'm not sur of :
Quote:
CG for SkyS V1, V2, and Bixler should be 60mm from LE of wing
On the french bixler forum everyone says that the CG is 68mm , not 60, do you all calibrate your planes for 60mm ?

PS : english is not my mother language

Jerry ( sayers1)
Balanced at 60mm?
Bottom of wings and tail parallel to each other?
Ailerons centered nicely in the neutral position?

Have you tried a power off glide test over some tall grass to check the airframe?

I know you know all this but sometimes covering the basics leads to finding a problem we all have over looked.
