Hi All I'm going to build a plane called The Ace 4-60.. It's an older kit..It calls for a 60 4 stroke.. I was thinking a 70 4 stroke..Does any one make a 60/4?? Any recommendations..
This will my 1st 4 stroke..Now thinking down the road whats is a 70 4 stroke = to in a 2 stroke?


Thanks Dan

I was looking at the Magums cause of price.

70 4stoke = 50 2stoke

A OS or Magnum/ASP 70 four stroke would be fine in the model.

The ACE 4 series were designed by Doc. Matthews to fly on the wing as the saying goes, they require very little power for flight. A Saito .56 or .72 would be spot on perfect.

Magnum .70 is a sweet running engine.. The price is real good too.. Got two of them and love them...

Avoid the O.S. FL-70(ABC/ABL cheap junk) and the 70 Ultimate (lemon). The 70 Surpass II is good, though.

O.S. FS .70 all the way, I have been running a couple of OS .70 for about 8 years, no problems!
