The manual says to put the LONGER Interplane Struts in the BACK and the shorter ones in the front.

I just read a review in FlyRC where the author states that there is a misprint in the manual and the longer ones are supposed to go in the front.

I emailed Hanger 9 but have not heard anything. Does anybody which way is correct? I also did a fair bit of ARF bashing with this kit. Stripped off the plastic and did cloth and rib stitching and a bunch more detailing thought you might like to see it.

Thanks

Looks really good.

The cloth look beats the shiny stuff all hollow.

The red/white stripes set it off. Really nice.

It appears the struts as you placed them worked. Have you checked the incidences of the two wings?

SWEET !!!!!!!!!! Looks great.

Thanks. I have not checked yet. I'm not sure what incidence they are designed at and that's why I concerned with the conflicting report.

From the looks of all the struts, it appears that the cabanes wouldn't fit properly with the interplanes switched. Was there a foolproof way to insure the cabanes were correct? If there was, then the interplanes should be.

there is maybe 1/8 of an inch difference between the two struts. So it's not a big leap to make them both fit.

With the incidence being primarily set by the lower wing saddle an the cabane struts, some trial fitting of the interplane struts should show what is right. It sure seems to me that the longer ones would go in the back.

As I recall, the H9 Camel has a faily flat bottomed wing. The aft strut would then be the longer one, as the lower wing airfoil changes thickness (gets thinner) in height towards the rear much more than the bottom surface of the low wing changes in height towards the rear.

The front strut is not far from the lower wing high point on the airfoil, so it makes sense to be the shorter one.

I have done a couple of ARF WWI biplanes lately and they were all arranged with longer aft interplane structs, due to the way the airfoils change thickness.

I could certainly be wrong, but a go either way with an incidence meter would tell the tale.

I reviewed this plane for RCU Magazine and I put the longer struts in the back as per the manual with no problem Putting the longer struts in the front would create more lift, and believe me, the last thing this plane needs is MORE lift.

i still have not heard back from Horizon Hobby but I feel that you guys have given me the correct direction with the longer struts in the back. Thanks for the feedback and have a good summer of flying.

The struts on the camel, longer ones at the trailing edge and short ones in front. I talked with the teck guy. I did it and it flies ok.
