I just recently received this model and it stated that it was an open box and that the Landing gear is not the right one inbox however it stated that the correct one would be included when I opened it up and looked at parts there was not one in there has anybody else had this issue?

Mine came with the correct landing included in the box.

Who else out there has purchased and assembled the Skynetic Trainer King. I purchased the Open Box version. Wondering about the experience other owners had assembling the wing halves together. Especially since the wing half roots are not beveled to maximize contact surface area. Tried numerous times to get Customer Support or the online Help Center to tell me the measure of the dihedral angle. Best advice I got was just assemble using the dihedral braces and don't worry about the gaps. What experience have others had ????

[TomZawodny]

Ok, have not heard from anybody about their experience building/assembling the Skynetic Trainer King soooooooo I'll start off. Don't expect this to a glowing endorsement ---- it's not. I'll be listing what I feel are severe shortcomings with this model. By the way, I purchased the OPEN BOX version of the model and followed up with the purchase of another fuselage kit because off problems building the original.

1. All the EPP/EPO foam parts appear to be laser cut BUT all the cut edges are not flat --- they are concave inward. Do not have any experience to know if this is typical of EPP/EPO foam. Seems to be that glue joints using CA would be questionable. In my 'build' I am using either Foam-safe, gap-filling Medium CA or FoamTac; build time is greatly affected by adhesive cure time (I am not using CA Kicker). The foam seems to drink in thin CA.

2. Both the OPEN BOX kit and the separately purchased fuselage kit are supplied with numerous foam and wooden parts that serve no purpose in the model.

3. Assembly instructions available online and assembly videos are very lacking; steps are addressed quickly; pictures lack detail.

4. Supplied control horns do not match the instructions or videos. The ones provided in the OPEN BOX kit were totally unusable; when I complained, MortionRC sent me replacements which, of course, did not match those shown in the instructions or videos.

5. Roots of the main wing halves are not beveled to provide dihedral. Joining the wing halves using only the dihedral braces results in gaps along the mating surface which is unsightly. The MotionRC Help Center could not identify the dihedral angle for the model. They suggested propping up the wing tips and sanding the foam roots to add dihedral. Has anyone tried sanding EPP/EPO foam ??? I did join the wing halves together using only the dihedral brace but I used West Systems epoxy as the adhesive; seems like it will be strong.

6. The bottom surface of the main wing has SOME curvature; it is supposed to sit on a flat mounting surface/slot on the fuselage. Conversely, the horizontal tail is flat; it is supposed to sit on a curved mounting surface/slot on the fuselage.

7. Horizontal tail doublers (foam part #8) are provided to be installed on the outside of the fuselage tail. These appear to be overkill and would add unnecessary weight to the rear of the airplane, potentially making it tail heavy --- which is NEVER a good thing.

8. The ailerons each deflect down easily but are quite stiff for upward deflection. The hinges are EPP/EPO foam; no suggestion is offered on how to make the joints more flexible for upward deflection.

and lastly (for now) --- 9. I personally find EPP/EPO foam pieces (like for the fuselage 'crutch' structure) very difficult to work with. Very pliable, doesn't stay in place.


I'm SLOWLY working thru this assembly/build; most trying experience I've had with RC models. I hope no additional 'build' issues surface; I can only hope for some kind of a rewarding experience when I finally get this bird in the air.

[TomZawodny]

New(er) Skynetic Trainer King question: stiff hinge lines. Almost all the control surfaces are very stiff to deflect; andif they do under servo power, I fear that they will not defect uniformly across the span of the control surface.

What can be done to loosen the deflection of the control surfaces ???
