Gary,
Is this the re-engineered canopy system? You sent a manual on 3-9-2016 for the canopy system you had at the time, will it be the same system? Still need parts.

I did make a small change to the slider manual that you will not have. In step #4, I have you drilling a 1/4" behind the rear rails. I now drill these holes in the front of these rails. It is less visible there.
I also added a paragraph regarding the Corsair canopy in general. I regard it to be a more challenging canopy to articulate. Patience is needed. It can cause you to learn a whole new language. That being said, it is a beautiful thing to see a Corsair landing with the canopy open as they did in full scale.
If anyone needs the latest manual, just request one with an email.

Corsair CG
So I see from this thread that a significant amount of nose weight is required. I did my CG yesterday at our clubhouse and found that without weight, or the canopy installed yet, I am already nose heavy. To qualify this, in my build I moved all the batts to the front as much as possible. My thinking here was if I need weight I might as well have it as useful weight. I'm using a Powerbox Mercury with two 5800 mah hard plastic case lipos. In addition a 5000 mah batt for the gear, and another 3500 mah for the ignition and pump. So in total 4 batts moved far to the front.
I used a Xicoy CG meter for this. Measurements shown in pic.
I used CG as 10mm in front of main spar as per CARF manual.
The weight addition point for the CG meter was taken as the front lip of the cowl if I needed to add weight there.
Total weight as shown was 22kg. 48.4 lbs.
Any comments on this, I just want to know on the models that needed a lot of nose weight where were the batteries located and what size were they?

Batteries can certainly be used as ballast. The manual states 10 to 12 MM. That is looking straight down on the front side of the spar. I have found this to be 6 1/2 to 6 5/8" from the front of the wing saddle. This is tried and proven to be a great balance point. Remember that our builds all include scale cockpits and pilots, all of which is behind the CG. A stripped down ship will obviously require less nose weight.

Hi Gary. Thanks for the CG dimension. I plan to have the sliding kit from you and a pilot figure, so I'm thinking at least I'm in a good starting position with about 400g nose heavy.

Gary,
please check your PMs. This has reached the point of unacceptable. This has to be a world record for getting parts. I have given-up. And please don't make further excuses and false promises.

Dan,
It appears you did the CG check with the gear down and you want to do the CG with the gear up and make sure you're at the CG location. You'll be flying with the gear up and that's a significant amount of weight moved backwards. I found that most people need to add weight up front. We're all familiar with the old saying about nose heavy versus tail heavy.

small decal marking locations
Does anyone here know where I can find where to put the small markings on? All the pics I have downloaded you can't read them.
I got my decal set from Taylormade and they included a few sheets of the military access panel markings.
This pic shows their existence but cant make them out.
Thanks in advance.

No, I have the world record for waiting on parts, and you can forget getting a reimbursement as well. Gary, I don't get how you can post all this stuff on YouTube and build sites and screw people over.

Добрый день!
Извините за вопрос, сколько вы набираете вес, без топлива!
Я получил 23,110 кг
Я в шоке, чемпионат позволяет только 20 кг и 5 литров топлива ...
