.074 or .15 engine for this plane?
I just bought a AKM model p 40 warhawk E plane http://ak-models.com/electric_p40.htm
Do you guys think i can stuff a AP engines 15 in the cowl or just stick with a .074 norvel or a AP .061? the 15 would weight about 2 ounces more than a gws 400 with gearbox. the 061 and 074 norvel would be about the same or less weight.
Are the AP engines good reliable engines? how does the 061 compare to a norvel 074.

the AP061 is a bit less powerfull than the Norvel 061, the Norvel074 is little better than most .10ci motors , ited be as good as the AP15 but lighter.

if you build it light with light RC gear the AP061 will be fine , if not the Norvel074 will rip it along .

grant,
Just know that the "brown" is painted over plastic covering. You might want to contact them to see if it's fuel proof.

A friend of mine has the AP .09. Same case as the AP .15 with a different piston and head. Way heavier and less power than a Norvel .074. The .09 puts out .25hp and the .074 puts out .38hp.

Grant,
An AP09 will swing a 7x3 at around 14,000rpm IF its a good one, the Norvel074 will swing the same prop at approx 16,000rpm and is much lighter. I have am AP09 it only makes 11,600rpm with the 7x3 a dissapointment, which I am led to beleive is not uncommon.
