Saito FG90R3 Break in. Saito Radial RC Engine 

Love that sound. Nothing like hand-flipping to start it though.

Nice sounding engine. Sweet Biplane!

Sick motor love the saito motors 👍👍👍

Great Job! Thx for sharing :)

When I ran in my 60r3, woah she made a big mess!

Awesome Waco, did you cut the front of the firewall to get the fg 90 to the 170mm length??. Cheers

Yes it is,,. it is Phoenix models from tower hobbies

Hey, nice video, I see you have a sort of attachment that lets you get the adjustment ALLEN key in easily, could you please let me know what that is and is it made or bought thanks

What prop reamer did you use to open up the prop to 15/32 size hole. Quite a bit bigger than usual 10mm hole.

I like the way the engine starts. My Saito doesn't lol.

Is that a Waco? If so which brand?

I want a motor like that in a P51 model!

Wieso hat dieser schöne Motor diese hässlichen Kühlkörper zwischen den Zylindern, sind diese notwendig. Ist doch zusätzliches Gewicht.😱😱😱😱 Viele Grüße aus Germany
