This model gets very good reviews for its flight characteristics but it has a few weak points. As I built it, I designed some parts to address these areas. Then, as I crashed it, I also added some replacement parts. These parts should also work for the L-4 Grasshopper sold by Hobbyking as it is the same model with a different paint job.
If you don't own a printer, you can upload the files to me via 3Dhubs and I can print them and ship them to you: (Or you can choose from other printe in your area on 3Dhubs and save on shipping.)
My replacement and improvement pack coists of:
Landing Gear Left, Right, and Cover - The main parts of the landing gear are two triangular pieces of thin plastic. They will break. I've made reinforced replacements for them.
Landing Gear Cross Brace - If you are not worried about the scale look, you can print this using Ninjaflex Semiflex and string it between the two axles to act like a giant rubber band / shock absorber. It is designed to replace all the fiddly little springs and flimsy plastic parts which look like they will break if you sneeze on them.
Landing Gear Hold Down Plate - The front of the landing gear, which coists of the metal bar that also serves as the axles, is "attached" to the plane by pressing it into a plastic slot. It is likely that during a rough or uneven landing, this will come out and the landing gear will fold backward and shear off, probably ripping off your wing supports along the way. This part and three small screws should save you from that.
Landing Gear Mounting Plate - This is the plastic part that is embedded in the foam underbelly to which the landing gear is mounted. There is no reason to use my veion over the stock, it only serves as a replacement if you is damaged. My veion is identical to stock except for the addition of the three holes used for mounting the Landing Gear Hold Down Plate.
Elevator Bridge Stiffener - The elevator is just foam, and the control horn attaches to the right side of the elevator. The skinny bit of foam that connects the left and right sides of the elevator (the bridge) is too flexible, so the right side is going to actuate more than the left. I'm no aerospace engineer, but I think that is a bad thing. Glue this stiffener to the under side of the elevator and you won't have to find out how bad.
Battery Cover - The stock one is probably fine, but I chiseled away some of the height of the battery compartment in order for the battery to actually fit, which left the front of the cover (the part held by a tab) too loose. If you are in a similar pickle, this thing is for you.
Wing Latch - This is the clear plastic part that gets sandwiched between the two wing halves. It forms the top of the cockpit and the sun roof. Its main function in the model is to provide a tab that fits into a slot in the front of the cockpit in order to hold down the front of the wing. My veion should be more or less identical to stock and is only needed if you is broken.
Wing Struts - The plastic pieces that brace the main wing. I broke up the main strut on each side into three pieces so they will fit on most print beds.
Skis! - These worked great on icy-crusted snow. However, they may be too small for deep, fluffy snow. Thanks to the built-in leaf springs, they are designed to be used without the need for external springs to keep them level during flight.
Hub Cap / Wheel Nut - You know, the plastic part that holds the wheel on. I gave up style for functionality on this one. Itead of saying "CUB" on it, I made it 2mm thicker with a " " slot on it so that you can use a flat-head screwdriver or even a coin to tighten it.
Hub Cap Cub - A more stock rendition of the hub cap with the "CUB" text on it.
Wing Strut Anchor - The plastic part that gets glued to the undeide of the main wing to which the wing struts are attached. If that doesn't make see, just look at the part and you'll get it :) These should be pretty close to stock except I did not bother with the slight curve to the top surface.
Tail Strut Anchor - Same thing as the Wing Strut Anchor, only smaller. These go on the horizontal and vertical wings as mounting points for the springs that supposedly reinforce this section. These are pretty close to stock except I beefed up the loop in the hopes that this will actually be printable. I haven't tried it yet.
Steering Holder - This clips on to the bottom of the rudder to steer the rear wheel. Mine should be pretty near to stock.
