    CG, I did notice this bird is a bit nose heavy. Even with X2 6s 5000mAh batteries in it, all the way back in both compartments. I hid a very small amount of weight in the foam nozzles. I cut out a small area, glued in the weights, then covered with painters caulk. I did paint it black after it all setup. Sorry no photo. CG is perfect.

    One cosmetic issue that drove me a bit nuts on such a large beautiful model like this, was the canopy had a gap under it, where it meets the fuselage. This also keeps the magnets from connecting together in the middle. In the one photo, you will see small black dots. This is where I kept sanding the foam down until it seated nicely and the magnets would hold together.

    When working with the elevators, I noticed the aluminum control surface horn had an uneven surface around where the holes had been drilled out for the linkage ball to be bolted on. This kept it from fully seating flat on the surface. I removed this with a hobby knife. I just felt this would make for a stronger tight seat and also insured the bolt reached the nylon in the lock nut.

    Some personal touches to the elevators. I added some weights to balance them. This aids in smoother control. The servo is not under a load while they are level. So this creates a neutral balance. As you can see in the photos I made a small slit on the side where I could move the weight forward or backward to achieve balance. Then glued them in place with foamtac or silicone will work. I will also include some photos and measurements of my control rod setups. The 30g coreless servos are a bit of an overkill for the elevators in my opinion. They also seem more on the side of heavy duty use then finesse. They have a "ratchet" action to them. Not precisely smooth. I did install a Hobby Eagle A3 Super 3 and changed the servo frequency to around 165Hz. This helped smooth them out a bit.

    Freewing MiG-29 Review

    Hello Fellow Pilots,

    I recently received the latest version of the MiG-29, with the new 30g coreless elevator servos and wanted to share my impressions of it.

    The Jet comes boxed very well, amazing how they fit all the parts in there. Speaking of parts, most of this model is in just a few large sections and assembles quickly. There is a nice place for the ribbon cable to be stored to the fuselage when the wings are detached. Nice touch. Construction is strait forward and simple. Instruction are clear and easy to follow. only issue to mention in the build, is the flap push rods. I had to go to the outer most hole in order to get them to reach. I also noticed the elevator servos, bypass the blue box and are now Y'ed together. One very positive note to mention is the ordinance. The missiles are of the best quality I have seen Freewing offer on any jet thus far! A funny thing to mention, but on the subject of building and testing. I noticed with this plane my servo tester could not lower and raise all three gear together. Only one or two would work at a time. All three worked perfectly together when powered off the receiver.
