These sliders are going into the aperture from the Inside, and I fix the canopy with some small screw. It works fine and its simple to make. The canopy is closed with 2 magnets.
You see also my solution about the complete hatch fixture, I make 2 brass tubes with an piston Inside, that hold the hatch in position, and for opening I move the both stem in forward position. In the front, I have the originals bolds, that works fine.
preparing for the warbird04 sliding canopy set up 😃

Mine La-7 is in progress with painting and weathering...it is a long job, but the result is Worth it.
Yes we are a little alone here...but it is good that we report about the construction, I am sure that helps other people who want modify an La-7 cy models...even later.

that's for sure....I've been looking at the CY P51 Mustang as well. I was glad to see another modeler doing a build thread on it. It looks good too.
Post some pics of your La paint process when you get the time

my holidays are finish...and the job is going slower!
The fuselage is finish with paint job, the motor + ignition are mounted. I look for the best layout of Rc components, I must have in mindes that I have a light motor forward. This obliges me to forward all hardware.
I post a picture later on the future layout solution.

You got and incredible job on your La-7 dear Jimmy, be continued.

Question: do you have an idee about the right CG location?
Some people take it at 195mm from the LE...
What about this?

what I did warbird was set the CG at 192mm at fuselage wing root leading edge...that's near half of the recommended 190-195mm CG range.
I personally like my airplanes to fly with a CG that puts the airplane straight level while inverted on the balancer. Ive always had good luck with this set up. I know I'm a ways from balancing and flying but it's exciting to see you get to that point with your La
I hope this helps

Dagg, those both nice machines there, & I will be applying what you've shared thank you... I don't have hands on experience with running radials, but from what I've gathered, guys have built air dams so air flowed past each individual cylinder- then funneled into cooling passage..?? Still following you guys progress with enthusiasm. Thanks again for sharing, you too warbird

Default La-7 Cy models correct CG

Hello,

On the first picture, you can see that i have mounted both tanks (gazoil + smoker), + gaz servo + smoke pumps as close to the firewall.
Next picture you can see what solution i have to obtain the correct CG. I can take the accus + servos for ruder and rear retract in front of the CG. I hope that with this i can balance the La-7 without add some lead.

nice work warbird...looks like you have everything forward as possible so maybe you can keep within the CG range. 195mm should be ok even though it is the most rearward setting. If you go with the 195 setting you might consider reducing the amount of elevator through or set up a dual rate that will help you in the maiden. You look very close to the first flight and can't wait to hear what you have to say about it
good job
👍
