I am looking for suggestions on a good "speed" engine and pipe for under/around $200 and looking back through the forums it looks like the Rossi/Morris .45 is supposed to be pretty good for $150. While looking at that engine I saw the MVVS Q500 for $170 ( http://morrishobbies.com/product_inf...products_id=98 ) and it looks good too. I also read that the Webras are supposed to pretty good.

I would also like to find info about modifying engines.

Thanks for any info,
Joel

What kinda plane you gonna be flyin'? If it is for sport flying/speed I would go:

YS-45
Rossi (Powerhouse)-45/53
MVVS-49
Webra-50
OS-50SX
Jett-50 $$

If you want all out speed:

MVVS is the cheapest way to go unless you want to modify a Ducted Fan motor like the K&B 7.5-

Keep us posted!

JoelD,
All the options put forth by Razor are good ones, especially the K&B 7.5 DF, it wins on a speed/$ basis.
See my post on thread http://www.rcuniverse.com/showthread...51&forumid=162]

its going on what I guess you could call a homemade whiplash....all I have to go by is wingspan and a couple pictures but I figured out enough to make a prototype and I'm gonna try make the mold tomorrow. All I have to put on it now is an old tower 40 (ported (beveled outside of sleeve) with good results without knowing much about what I was doing) or a 46FX and was just looking for something that was made to go fast. I think I will try to get it built and try it with my old .40 first....that way I can think about the engines suggested and decide.

Thanks,
Joel

Have you Clarence Lee's review of the MVVS Q500? He writes:

Our testing verified this, as excluding the Nelson and Jett engines, the MVVS Quickie 500 engine is the strongest running .40 displacement size engine we have tested to date...
I'm looking to get one as soon as Morris Hobbies get's them in stock.

For a delta go with the MVVS-40.... Since RPM's are on the menu!

Whatever Clarence Lee says is the law-

Thanks for the replies.....I was kinda leaning toward the MVVS. I started on the mold but didn't get to finish and probably won't for a couple days but if I ever get it done and a plane built, I'll tell yall about it.

Thanks,
Joel
