Note: JP Hobby landing gear, like most landing gear that are not delivered directly with the models, uses standard retracts, designed for the size and weight of the aircraft, but whose size brackets and the spacing of the holes in the brackets may vary. JP Hobby manufactures a number of retracts in different sizes but cannot offer a specific model for every make and model on the market. An adaptation of the mounting plate may be required.
