Hey Roger on the Boost Tabs, when you get to doing the linkages for all that I would really appreciate some good up close photos of all the linkages. Help me get the best understanding of them possible.

will do

doing the stab/ele the same way as I did with the wings, I have never done the tail end this way so this is a first , but it should be OK
in the pictures , you will see two sets of templates, I found it easier to put the first with no cuts for the spars , then simply replace with the other one with the cuts for the spars.

cut the top, and grooves, and fitted the mini spars

while the top sheet glue is setting, I started on the boost tab hardware , the two color photos are of my laser wing, I am using the same hardware, and these are 2-56 size, you have to remember the tab is barely the size of a 1/2A airplane aileron

Those clear things up a lot for me Roger. Thanks. Now how well would it work for a 3D plane where we are looking for max throw we can get out of a surface? Just looks like it may limit the amount of travel you can get but then again it may just be how I'm looking at it.

 

[Forgues-Research]

The large throws for 3D setup don't lend themselves well to boost tabs, unfortunately. the rule of thumb for boost tabs, is the tab should have a surface area of 10% that of control surface, and have a throw of about 30% that of the control throw.

Thanks. I plan on building a good size T-6 Texan some day so boost tabs may lend themselves well in that application .

 

[Forgues-Research]

The T 6 has boost tabs on the ailerons that I know for a fact I have touched them LOL

a bit of throwback thursday
