This model is based on it’s bigger brother, the YAK55M 33% . This airplane was developed for the 50-60 cc gas and  the 4-5kW electric motors.  This model is for all diehards and sport pilots, flying either scale aerobatics or 3D.

Once built, the model is extremely easy to fly, as almost no corrections are required, proving once more the excellent quality of this kit.

With small movements on the control surfaces, it flies extremely accurate, and direct, whereas the 3D capabilities are amazing, when using the full control surface deflections.

Gas Setup:

The GP-61 Specs:

Displacement:61cc

Weight: 3lbs 2.8oz

Horsepower: 6hp

RPM:1600~8900

Warranty:2 years

Includes compact style side dump muffler, and LiPo Ingintion.

For Germany, the side dump muffler is not recommended, as the noise level is above what is legally allowed. Here, I have used the MTW system, with a front in, rear out silencer, and header custom made for the Krill and the GP engine. Please contact MTW direct to get an offer, and great quality muffler and header. (click on the image to go directly to MTW)
