I went back out last night and pulled all the tape and masking off....that was my first time using latex paint and it went on really well.

Thanks BobH, Ill be headed back out to the shop this morning and take a few pics to post. Latex is sure easy to clean up after the job

Jimmy,
I like using Latex too. It sprays nicely and cleans up super easy. It does have to "cure" for some time at least a few weeks.
I also clear over it with minwax ploy satin clear for protection.

Tomorrow I'll hang the engine and balance it

Hello Jimmy,

You make an incredible job on the La-7... continue so! The result is perfect, and i Wonder to see the maiden.
After balance and final assembly, give me please your final weight.

For me, the Lavotchkin will be ready this afternoon. I send you some details pictures about the result this week-end. The maiden will go next week, this time we have some rainy day...

In the german forum about the Cy Model La-7, i find an info about the deflection about the control surface:
- for elevators, +/- 6 cm at largest point.
- for ailerons +4.5 cm / -3.5 cm at point near the flaps.
- 25-35 % expo on elevator and aileron
- CG is confirmed at 195mm measured on fuselage side (as discussed previously)
See you soon.

that is very good information warbird 👍 So the CG being used by others is the 195 mark which is the furthest mark back according to the manual recommendation. That will also help with the task of balancing since the moment to the planes tail is so long as compared to the nose moment.
Thanks warbird those measurements will be of great help
