goldberg extra 330
 

i did alot of resurch about engin choices for this plane almost everyone on here said a 50cc gas engin was too much but they all were using a fuji or a zehnoa very very heavy engins 6 lbs pluse i went with a brison 3.2 3.25 lbs half the weight of the others with a mejzlik 22-8 and the airplane flew awsome i didn't use any high rates cause it was the test flight but the performance in up lines was great i did a few imac menovers and it performed awsome tracked great and was very persice i did not do any 3d beaing it was the test flight but i think it will not have a proulbum preforming in any 3d menover i would recomend using this engin to anyone who wants to build this plane
