IMAC Incidence Meters

[IMAC FANATIC]

Off topic but anyone flying with positive incidence?
Ill start a thread if needed for that discussion.

If I was to use one i would use the Robart. With that said I would save your money and use the datam line or the top of the fuse without the hatch on. You can use a long 6' staight edge but make sure it true and not bowed or use a string line in same manner and measyre down from it to LE and TE of wing then do same for the H-stab. For me I dont trust any of the meter readings as much as a solid measurment. You do the same type of measuring for other than zero incidence if need just have to do the math. Just my 2 cents.

Thats mostly an imac thing, same with and kinda goes with the down elevator to low throttle mix Imac guys use.

+1 degree in the bottom wing....... But -1.5 degrees in the top wing, does that count? lol

Second the Robart incidence meters. There are extra long bars available now . found the digital type not trust worthy.

I didn't know they had longer bars available now, I need one!

I'll probably get laughed at with this, but since I only "build" aerobatic planes. I have gone to using a tape measure and very carefully measuring from a known datum point. I have not used an incidence meter for my last 5 wing installations and normally require only 1-2 clicks of aileron if any.

What was recommended to me by a respected pro builder is to set them by measuring and verify with a meter. My battery's went dead in the meter two builds ago...

That's how we go about doing it with full scale planes that we rebuild
