[NSRCA-discussion] Integral Landing gear

[Vicente "Vince" Bortone]

Verne, 



Just curiosity .  When you said "add 1/32 right thrust", means to add to the one is already set at the nose ring?  Is 1/32" is at the tip of the prop? 



Thanks, 

Vicente "Vince" Bortone

John, 
With the stab at 0, make the wing .5 positive, reduce the down thrust to .5 
down, and ADD 1/32 right thrust. I'm currently finishing my third one and 
got it right on the second one. Now I'm just duplicating it. Actually, the 
first one flew great but needed some mixing. With the settings I just gave 
you, it'll track straight forever on either knife edge with no mix. The 
extra right thrust was to eliminate a slight left drift at the top of tall 
verticals. I left the stab at the factory position and called that 0. Your 
wing will actually be slightly negative to that so you'll need to increase 
the incidence to .5. The nose ring has a little over 2 degrees down so 
you'll need to remove 1.5 degrees from that. Can't help on the gear, I used 
Bolly F3A Longs. BTW, set the CG at the LE of the wing tube or just a little 
rearward of that, like 1/8" or so. Hope this helps.

The landing gear legs I received with my Integral weigh 6 ounces and are 
very rigid as well. I noticed that when Jason listed the weights of the 
components on RC Universe that the gear legs were listed at 3.2 ounces 
which is a substantial difference. 
This will be powered by a YS 170. I haven't checked yet but I intend to 
add adjusters if necessary to achieve stab incidence of 0.0 degrees and 
a wing incidence of +0.5 degrees. 

 I have three questions that I would like to resolve before I get any 
further along. 

1. Is there a replacement gear that is lighter and in particular more 
flexible?  Height of the gear should be about 8 inches. 
2. Should the downthrust be reduced from the approximately 2 degrees 
built into the nose ring to about 0.5 degrees down or ? 
3. Should the sidethrust be reduced? 

Would appreciate help from those of you who have already run into these 
problems and found solutions that are working for you. 

Thanks
