I am presently completely one of the 330 L ARFs. Upon initial inspection, I had one wing that was warped! It was my right panel. If you look down the leading edge, it had a warp to it! No question about it. The trailing edge was perfect! The left panel was perfect! So, upon trying to iron the warp out, stare the warp out, and want to jump up and down to get it out, I also noticed that the right panel was thinner than the left! I finally removed the covering on the right panel, to find a nice warp, and lots of sanding by a factory worker! The panel was sanded so much, the sheeting was very thin. It was about an 1/8 of an inch difference in thickness or just under. Maybe it would not have mattered, but you know what, it bothered the heck out of me! Here is what I did: I cut into the wings leading edge and part of the sheeting, corrected the warp, and reinforced. It was at the 2nd or 3rd rib from the tip, so I added a shearweb and extra fiberglass ect. to reinforce my cut. Now the right wing was perfectly straight as the left panel. I next added some 1/32 sheeting to the top and bottom of the right panel. Yes, I added a little weight, and had to rip all the covering off the right panel. Yes, Im crazy! But it worked! I had to do some sanding, and fitting, but now I have two perfectly straight and strong wing panels. I realize no ARF is perfect, but that dont mean you have to settle for warped panels. I could have had them replaced, but customer service at Dave Patricks is very slow to respond. So I took matters into my own hands. Oh yeah, my stab tube was not mounted quite right either. I cut it, and repositioned, and added spacers and glued back together. Now the stab is in perfect alignment with the wing.

Now for the clincher! I have fitted a Zenoah G-45 Rock to my airplane, per Dave Patricks OK! Yes it is on the heavy side, but it sure does look sweet! Its the only engine I had, and have been wanting to use it for something! (other than a paper weight!) According to Dave Patrick models, CA hinges, and the Zenoah G-45 will be OK. (I put 5 CA hinges in ea. Elevator half, 8 CA hinges in each aileron, and 5 CA hinges in the rudder) So, Im going with it! I would put the robart hingepoints in, but you know these arfs, not enough trailing edge for proper glueing without modifying. By now, I have done all the "mods" Im going to do. Im using Hitec 945s on the elevators, Hitec 5645 digitals on the ailerons and rudder. Good luck with yours and wish me luck with mine! (Im gonna need it! ha!ha!) By the way, dont try to change my mind on the G-45, as this is what I have, and this is whats gonna fly her! Ive been hearing you need extra weight up front to balance anyway! I should not need any extra!
