It seems to me with all the mods you made up front that you should be more forward than rear CG? I've added all kinds of crap to mine and never bothered even checking the CG after the initial setup. Granted I did not do all the mods in one go so had chance to fly between upgrades. I have found myself shifting my Zippy 5000 40 c at about 830 grams to the rear bit by bit and it flys awesome.
I did CG with gear up(retracted), I'll try that again with gear down see the difference. Yeah you'd think I'd be nose heavy for sure(Pilot mod, airbrake, and batt bay mod) All mods forward of CG--but its still carrying more weight in rear
Curious what your current CG is at!

I re-did CG with gear down, I had to move batts towards rear about 10mm, so I'm as ready as I'll ever be, first good weather(Sunny day) I'll maiden at 155mm

Good to hear that. She flys really easy once up in the air. I use 40% expo on all surfaces and take off and land without TV's. I suggest that you find yourself a good runway for maiden and not the beach where you normally like to fly. This model can really suck up gravel and sand. Ask me how I know that... laugh.

Biggest issue with test flights are breaking ground on takeoff. She tends to have a long roll out until you get used to the elevator flip to get the nose up and away. On landing keep some power on and set up the glide slope so it is nice and flat with a predictable decent rate. Just like the real thing use power to control decent rate. To much elevator with low power can get you into a very high alpha at touch down so just breath and be gentle on the sticks. Once you feel comfy then you can do military pattern and short high decent landings no problem. She has a nice flat decent rate from altitude if needed but carry a little power.

This is one model that is close to flying a real jet in its characteristics. I have tried all kinds of maneuvers similar to when I flew full size jets and it tends to be similar in response to most attitudes and control inputs. This is why I like this model so much. Its the first model that behaves correctly that I have flown and I want a larger one around six feet or so with twin 90's for contest flying.

So relax and enjoy. Break a wing... or is that a leg?

You guys are making fun of radar but you can actually add it to this model is you want.

There's a thread that has pitot velocity input to adjust gain control gyro's. It also has radar that triggers the gyro to input ground avoidance impact.
Slope gliders use them. So if you really want to, you could add the same to the SU.

But I'd fly the SU around first before you think abou adding that mod.

Ha I've broken plenty of wings but thanks! I have the grey camo also I'm running on 6s, flew that plenty of times-- you're right - its great jet, my favorite EDF! I'm still a newbie really, first flight(CRASH!) was in 09, and I've been hooked ever since... And yes I WILL NOT MAIDEN ON BEACH-- of course my official dirt Mars runway destroyed my Su-34 fans twice, and an F22 so my goal is to somehow get to the golf course, or a big soccer field at UCSD when no ones there(Might be impossible).
All systems are go, so weather permitting I'll get her in the air this week!

Telemetry,High Speed Dual Axis Gryos and Onboard Radar
The telemetry is Hitec based but it will still work with any system. And because its on board, it doesn't need a lot of TX adjusting other than the extra channels for fine tuning the gain. But once gain is set, the pitot reads the air speed and adjusts the gain there after. So as stability control goes, 3D to speed, this is an excellent working setup.

First line, hot link in my last post #6684.

Let me see if I can find the video that demo's and describes it. But the thread had all the info.
