KRAGA Maripi

Maripi is easy to fly airplane designed for acrobatics training and simply having fun in the air.

The wings have couple important improvements over Kodo. Most significant change is new leading edge design. Thanks to that the airfoil shape is more exact. The airflow is laminar on bigger part of the wing and the plane behaves more true to the aerodynamic simulations.
The wing is also lighter due to the thinner mesh with bigger spacing.

The fuselage is also a new design to make sure it is printable on wide range of 3D printers and as light as possible.

This is by no means the best way possible how to setup your plane.
It is just a brief overview of possible options that I believe could be good starting point for beginners.


To avoid problems when setting correct CG, it is recommended to use motor weighting 110g. You should be able to fit inside motors with diameter up to 35mm. Good option is Turnigy Aerodrive SK3 - 3536-1200kv Brushless Outrunner. This motor provides plenty of power even for hovering figure.

Optionally you can use programming card but It should work fine out of the box.


Although there is plenty of space in the fuselage, to be able to set correct CG, you have to place ESC and Battery next to each other right behind the motor. In this configuration ideal battery weight is 120g - 140g. Turnigy nano-tech 1500mah 3S 25~50C Lipo Pack is one of many options.


This depends on your transmitter. Only requirement is to have 5 channels or 4 if you are going for pure glider (no motor).


In this type of plane it is important to use strong, fast and light micro servos especially the ones used in the wing. I opted for Hitec HS-65hb. It is an analog servo with karbonite gears.
