Building Tiger Moth from Plans by Flt Lt Gordon Whitehead, from Nexus Plans Service,
 
Hi there!
I had bought a 25 size Tiger Moth plans from Nexus Plan Service (UK) the publisher of RCME. The plans were designed by Flt Lt Gordon Whitehead. I need little help with the construction. I have started to build, the plans they sent were not blueprints or CAD drawn but some photocopy of old plans and all the markings etc are not very clear.

Where I am stuck is the dihedral for the upper wings, which is next to impossible to decipher from the plans. The lower wings have a dihedral of 1 7/8". has anyone built from this plan or has the plan?? Just want to know what's the correct dihedral mentioned on the plans??

Any help would be very much appreciated
Thanks

Nexus has a plan number noted on each. Which are you working from?

Your plan may be very old, for Whitehead is well into electric power now.

coosybaylumber, thanks for the reply I will have to check the plan number and maybe by evening (Indian time) I would be able to tell you. Tried checking for Nexus plans service but the site seems to be down. It appears the same plan is available from RCM, as thier plan number pl-793, Cat.2 the URL is http://www.rcmmagazine.com/e/env/000...m=plans:PL-793.
Will it help in some way??

1/. You wil get more response in the Scale forum

2/. Tiger moth's have the same dihedral top and bottom

3/. I think Gordon Whitehead is in the E-zone somewhere. He still writes for 'Flying Scale Models' as well.

Actually the Tiger Moth has less dihedral on the top wing than on the bottom.
The first prototype had the same dihedral as a Gipsy Moth, equal top and bottom. But with the swept back wings, the lower wing tips were too close to the grass for comfortable operation. So they increased the dihedral on the lower wing. It's something like 2.5 degrees each side for the top wing and about twice that for the bottom wing.

Thanks WIP (work in progress) actually you are right, the model has the same arrangement, 1, 7/8" on lower wings and 1" on upper. Was able to contact the designer himself and the gentleman has been a great help.
Thanx to all those who have taken the pains to help me out
regards

I stand corrected..the three views I have don't show that well at all.
