These engines are sreamers and they are very strong AVIASTAR



I Personally would stay away from this engine, as it is hit or miss... I purchased 3 of these engines, two .46 and one .53..  one of the .46s is a good engine, and the other I took apart to become a relatively inexpensive guinea pig for me to see what I could mess up with a moto tool..  (haven't done anything to it yet) the .56 on the other hand, fresh out of the box felt like there was sand in the cylinder, not smooth at all scratchy feeling..  couldn't get it to run  very well at all..  it's in my junk engine drawer..

there is even a forum specifically for the Aviastar .46, and even there the reviews are hit or miss.

so to summarize, out of the three aviastar engines I purchased, I wound up with, one great one, one turd, and one Guinea pig... 

Craig.

We have a great athletics department too War Eagle!

Timing the ports for slower operation would be helpful when you compare it to what a nomal JET engine is timed for.  The Jet engines are for small props and you want a bigger one.  But of course you don't want to go too far with that.  I would think the timing of the Fox engines would be about right, but with more exhaust duration to allow more power increase when using a tuned pipe.

Well, I know for a fact that Georgia Tech DOES compete in the AIAA Design, Build, Fly competition....and that's MY competition.  This'll be five year and 6th plane that I've worked on.  4th year and 5th plane.  GT has no hope against me!

 
Nor do they have hope against the Hokies in Football!



Well, I attended a competition about 7 years ago and I did not see GT there.  The last football game was almost a draw.  You won but we had about 5 defense starters out.  Hurt us in the Miami game as well though some of them returned.  Both offense and defense petered out as well.  Too many mistakes in the first quarter against Miami as well.

Yeah, DBF is most certainly electric.  They've always been 100% and won't ever change.
This glow engine is for the SAE Heavy Lift competition.

Well they've been showing up for at least the last few years.  They've always done pretty well, despite the quality of the school

Hokies? Didn't Auburn beat them in the Sugar Bowl a few years ago?

You're right, it does indeed say so. I saw they were prohibited in another class and must have thought I was reading the advanced section. Well then.. .. that opens up some possibilities!

[I still think a Sport Jett .46 on a wide blade low pitch 11" prop would be a serious contender]

hsukaria, those jocks do study.....their classes are just really easy, so they don't have to study much at all.

Tech's school of liberal arts is a school for Jocks.  Though there are many who take the management courses, and a very few who take the engieering courses.  I am told they don't do the jocks any favorites if they chose to take engineering, though I am sure the better ones do.

Yeah, I accept that. I just keep remembering my time at Texas A&M. One night a Domino's pizza delivery guy got stabbed in the athletics dorm. I guess somebody there wanted that pizza reall bad. I just don't have much respect for college sports.
