I have procured a Yak 54 with a 56 inch wing span. The plane says it weighs about 5.5#. I am in a delima about what power I want to use.
I am stuck between a Saito .91 to 120 or a YS 120. I have some experience with Saito's and OS four strokes and cannot decide. I have a 120 OS four stroke that I could use but it is in a Bucker Jungman by Carl Goldberg that I plan to sell with the engine in it.
Which engine between the Saito's and the YS would be best for this bird? Which has the best performance?
I fly Carl Goldberg Sukhois with 180 Moki's and like a lot of power when it is needed. I also fly a Bucker Jungman by Carl Goldberg with a Saito 180 for power. Just trying to give someone my power preferences.
Thanks in advance for your input.
