I now need to find a home for an OS 70 Surpass 4 stroke.

I was thinking a Funtana 50?

Flying style: Aerobatics, 3D!

Did you have to add weight to the tail, how was the CG?

Status: offline 		Yeah I hear the UCD is good with an OS70 but some have said on this and other forum sites its underpowered for that plane.

I guess some You Tube video will tell the truth )

Status: offline 		Seems like its more suited to scale planes rather than aerobats and 3D planes.

I gather its because of the weight?

I had my 70 in an Excelleron 50 and it flew well (still does but even better with a OS Alpha 81) but did lack a bit of punch.
