Just saw one for the first time today......flew great! It has a Saito 220 and flew awsome! Looks like a winner to me.

I'm currently building one and just recieved a Saito 220 for it....Was it 3D capable? Do you know what size prop was used?

He didn't try anything much at full throttle....but his prop was 20 x 8

I hope to use a 20 X 6 or 20 X 8 just not sure if I will get the RPM desired. I have a Saito 180 that turns a 16 X 8 @ 9500 but when I tryed an 18 X 6 could only get 7500. Was using 30% heli fuel...

go with 18-10 apc or 19-8 it should turn about 8800 or 8900 i have the 220 in the h9 - 260 - extra bill wrcflyer

Will it hover? the H9 extra 260 is similar in size to the Goldberg Yak. It would probably be a good indicator as to how the yak will perform..

So, Jerry... did you ask the guy if you could fly it???

No Steve, I did not for fear someone would chastised for such a request

Funny how that can happen, eh?

I need a new cowl for my 77" Goldberg YAK 54. HELP!!!!!!
