no just clag it on.

lol thanks for that scientific advice

I always add a little right and down jeff, about 2 degrees should do it bud.

Since the wing has a positive Angle Of Incidence
I'd agree with Keith

erm wot is positive angle of incidence.
i am new to this side of the hobby.

On fixed-wing aircraft, angle of incidence is the angle between the chord line of the wing where the wing is mounted to the fuselage and the longitudinal axis of the fuselage. The angle of incidence is fixed in the design of the aircraft by the mounting of the wing to the fuselage.

As good an explanation as any Jeff.

thanks Paul.
just fitted the motor and wired it all up and i've hit a bit of a set back on two front's.
1 i can not keep the prop on the motor, over half power, it flys of around the room.
2 when i do get it to stay on it has no pulling power, don't think it could pull the skin of a rice pudding.the motor and prop are spinning and fitted the right way.so ordered another motor.this time its more heavy as well as c'g is looking tail heavy not that i have any info on c'g. I'm going on the starting point of a third of the wing.I'm wrong please let me know.

1. you must have a Prop. mounting/Prop. Balancing problem (you Do balance your Props ? )

2. "no pulling power" This conflicts with your point 1. and sounds like insecure Prop. mounting

CG. Yes start at 33% its a safe bet and good starting point

ohh yes the prop is insecure all right.the motor has a built in prop saver and the gws prop will not sit on it right.its a silly design i think.the elastic band just will not fasten to grub screws.should of been pan head screws.

here is the crap motor. http://www.brchobbies.co.uk/?page=shop&action=additem&item=138

I'd put a longer motor shaft in it

the extended shaft will centralise the Prop.
and eliminate your offset Prop. issues (upsets balance)

Prop. savers though good in theory, rarely save many Props. IMO

well my motor came from brc today.i only did a phone order 1pm yesterday.
so this one can give me up-to 140 watts instead of my first motor at 50 watts,should go like stink or torque roll badly.

In other words jeff the front of the wing is up slightly lol

well my plane is almost finished.just need to shim the motor mount.must say for my first scratch build im pretty happy, the way it turned out.just hope after all the effort iv put into it it flys..

well jeff you should be proud of yourself it looks really nice,lets hope it flies.

Yes. looking good Jeff

Looks ace m8 welldone

thanks guys
i hope it don't end in tears

looks very smart m8 good luck

well me and Pete went to the park this morning.put the axn up and Pete egged me on to give the mustang its maiden.so i give him the tx and said go on then.so he did lol.
well wot can i say I'm absolutely gob smacked.it bloody well flys and Pete says it flys very well. so next time i will have ago my self.
so wots next .................b17 no think i will work up to that one.

Its a nice little buzz aint it jeff, now you know why i like my scratchbuilds, good on you m8 now set to thinking of your next build and maiden it yourself you'll get a bigger grin than you did today.

thanks keith will get some video of it next time.
also thanks for all who helped me along the way

well me and Pete went to the park today and i had a go with my mustang.it flys so easy and tracks very well.the slow flying is amazing doesn't seem to want to drop a wing.gos were you point it.its a keeper for sure. think this will get alot of air-time.
have done a video of it but needs uploading to you tube.
