RE: World Models 27% Ultimate
I have one of these planes and just love it. It had a few assembly & fit issues, but nothing too discouraging. I'll highlight
#1. Wing alignment dowels. I pulled them out of the wing, replaced them with 1/4 20 nylon bolt & hardwood block. Do yourself a big favor - pull off the bottom covering of the fuse, make a removeable plate, (under the wing) that way you can cinch the nylon bolts tight, and you have an additional compartment for gear. It is also a lot easier to install the pull pull with the bottom of the plane uncovered. and you can check the framework out in case it needs attention (i found a cracked former i woulnt have otherwise caught.
This modification took less than one evening, the surgery on the wing resulted in a small patch in the covering - no big deal.
I'll post some pictures if anybody wants to see how i did mine.
#2 The cabane mounts in the fuse started to 'woble' (i noticed this during transport when i would carry the plane by the center aluminum rib) I corrected it by cutting the square out that the 4 cabane mounts made - this entales cutting through the sheeting and foam. this exposed the 4 mounts so i could slide a reinforcing plate to reduce the flex. Replace foam and sheeting, recover. This was kind of a pain, but if you do it during initial assembly, it wont be so bad. I also glassed the inside of the box & firewall - that 3.2 has some umph!
#3 this one is easy- replace all those screws w/ hex bolts and blind nuts installed in cabanes. Also save the metal hinges for your screen door I used some Klett giant scale hinges
I'm running a brison 3.2 and its flys awsome @ a hair less than 16 lbs.
If you have a computer radio, take the time to mix out the roll coupling - its not as hard as i thought (if you have a buddy helping program while your flying), and its cool to see the plane KE across the field rock steady like the pros.
I took somebody's advise and didnt belabor the incidence issues, just fly it and adjust from there, there is alot going on with a biplane (aerodynamically)
