Im running into a possible problem, and wanted to share with you guys. I just overcome this situation with my Patrick 300, and Im revisiting on my H9 Cap 1/3 scale. The H9 Cap 1/3 scale is supposed to be designed for the Rocket city hardware, and have hard points already installed. Upon drilling for my Rocket city hardware on my elevators, I noticed that the elevators only have a hard point on the bottom! Nothing but soft balsa on the top! This is discouraging, as I went ahead and ripped off the covering to do it right! I added a ply plate to the top of the elevators, so the screw has something hard to secure it. There is not much "meat" in there between the top and bottom plate, so Im curious if anyone else has made this mod? Even my Patrick extra, had a hard balsa block, and a piece of ply on the bottom of the surfaces. I then added a hardpoint to the top, but they were originally designed for other hardware. The H9 Cap is designed for or is recommended for the Rocket city hardware. Anyway, after looking at my ailerons, it seems they are the same. I have not pulled any covering from the ailerons yet though. Anyway, just wanted to get peoples thuoghts who have this Cap, and what or any mods were made. Or....... did yours come with hardpoints top and bottom???

Hey Flymyplane

No mods made and she flys great!!

Glad to hear you did not have to make any mods. Iam concerned however, as to how well these surfaces hold up without a hardpoint on the top side? Without the hardpoint on top, my screw was "mushing" into the soft balsa, and I got real worried. That is why I investigated, and decided to install an 1/8" ply piece on top for each elevator. There is not much meat inside between the bottom hard point and the top balsa. The DP extra had harder balsa, and completely filled the cavity between the top and bottom of the surfaces. DP discouraged using the Rocket city hardware, as not designed for it, meaning no hard point on top. This is what makes me concerned for the Cap! Im very glad to hear of your success, it makes me feel some better, and I have not heard of any failures, so maybe Im just overly cautious. Its my first plane of this size (1/3 scale), and I just want it to be right. Im still debating on the ailerons, I guess I will drill the holes, and think about it! By the way, did yours or anyone else have a hard point on the top of the surfaces? Or is mine just a "fluke" thing?? Thanks for all responses! Much appreciated!
