After reading the very positive rating for the Fox Eagle .61 in the recent MAN engine comparo, I am looking at the Eagle .74 to put in the GP Shoestring. Have contacted Fox with some questions and am trying to get some specs, but haven't heard back from them. Is there someone out there who can answer the following :

- engine weight without muffler?
- Pitts style muffler that will fit up to the .74?
- 5% nitro recommended for breakin, can
10-15% be used for flying? Any problems?
- Fox website shows an "Easy Adjust" single
needle carb for the Eagle engines which I
guess means that it covers the entire range,
Would be great if it eliminates the low speed
valve. Do these carbs adjust well? Any
compromise in power?
- Any comments in general regarding the .74

Thanks in advance for any info. Joseph
