I had noticed that with the UMX Yak 54, the balance point of the Landing Gears towards the fuselage and its ground height relative to the 5.75x2.25 Stump Puller Prop may tend to lend itself to more Prop Strikes and Noseovers. Factor in wind during Landing Approaches and the chances of these issues increase.

Using the Landing Gear design of the UMX Beast 3D, I made my own Custom set of Landing Gears for the UMX Yak 54. The material used was .047 Music Wire, which is just as light as the stock Landing Gears, but is thicker and stronger. This Custom Landing Gear Set is also 1/2" longer on the legs, providing extra clearance height for the 5.75x2.25 Stump Puller Prop. The legs of the Landing Gear are also slightly raked forward, reducing the chances of the tail lifting up and causing a Nose-over or Prop Strike.

Additional modifications include the use of UMX Pitts S-1S Foam Wheels mounted on Dubro Mini Lite Hubs. The foam is very soft and allows excellent shock absorbency on impact. The plastic motor mount has also been replaced with a Small Parts CNC Aluminum Prop Adapter. The original Canopy Hatch that had the chalk-marked “3D” sticker has been replaced with a new Canopy Hatch that is unmarked for a clean look.

Field conditions were ideal for the Landing Exercises and Test, as it was quite gusty with constant changing wind directions. Landings proved to be much easier with this setup and the chances for Noseovers and Prop Strikes have been reduced significantly without reducing flight performance.

Problem solved. :)
