Looks Great Aero65! I'm Close, Just finished installing all my servos. I Still need to make the pushrods for the ailerons and flaps, secure the fuel tank, Balance, then wait for the snow to melt... It's been a looooong winter, and I'm (I'm sure I speak for all of us in the northeast) ready for some warmth and some stick time!!

Hey Guys, Finally good weather and I'm almost ready to maiden. However, I'm having a bit of trouble balancing her. It looks like I'll need between 1lb 6 0z to 2 lbs to get it right on... Anyone need this much weight in theirs?

Hi Phil
I had to add a bunch of weight also, Sounds like about what I added, I made a tray above the engine and mounted there, to try and get it as forward as I could.
I had it mounted to the front of my cowl baffles but my cowl mounts were taking a beating from the weight acting on the cowl mounts.
Sorry on the very late reply on the strut mount I used these
#670DB 1/2" dia RoboStrut Gear Door Mounting Brackets
I turned them around backward using the flat side I drilled and taped for 4-40 screws and used flat head screws to attach the door. This works ok, but the get off alignment very easily, I also had to remake my doors using 3/32 ply backed up with some thin poly ply fiberglass sheet from Frank Tiano.

Ok Gents, she's ready! My balance point is approx 3/4"-7/8" back from where ESMs suggested. On the front side of the main wing spar. The maiden wont be for a few weeks as this and next weekend are events, and I won't/can't fly a maiden with a huge crowd around.
I appreciate all the help from you Guys and will report and post a vid on the (successful) maiden soon.

Thanks Phil,
I got Saburo glued into the cockpit area. I also got the Raiden on her feet for the first time. Here's something interesting that I found out from a Japanese fellow RC pilot, their pronunciation of the word Raiden is "Rye-den"

Looks like you almost ready to fly her!

Maiden a success! The G62 pulled her around with authority. No trim needed! She was very stable at slow speed, and I didn't use flaps. I do, however, want to re-balance her, and I think she was just a tad tail heavy! She got a lot of attention at the field, and looked great in the air. I dont think anyone got a vid, but pics are coming in. Thanks for all the help and advice here! I do appreciate it Gentlemen!
