Is it true, that the new Evolution 61NX control line motor, is actually not a .61?
-
By my calcs from the data here http://www.evolutionengines.com/Products/Default.aspx?ProdID=EVOE0611, it's 0.5968ci in
Cheers

.61 cu.in. = 9.9961 cc
evo 61 = 9.781 cc
ergo at .5968 cu in. just about a 60.
They could have named it anything, but a name is a name, we just naturally assume that the "61" = .61 cu in.
I think it doesn't really matter unless it's used in a class that requires less than or equal to .60 cu in. To me it's a "60 size" engine.

At least it is smaller than advertised. Wait til you try racing and don't have the tools to check your engines. Several hundrds of dollarsw in engine that are illegal because they were bigger than advertised. Even in carrier engines. H^^

Doesn't Matter-Doesn't Matter!!! Were talking .0032 here!!! Hey, Hey I BUILD HEAVY-I need help!!! If you haven't noticed, we are in a recession!!! times are tough. Just cause you can handle that massive a discrepancy, doesn't mean I can.
Do you what its like tossing and turning night after night after night, because you know you are going to have to pull that stooge with a .0032 deficit. I mean, like I am having a meltdown here.
Ooh-Ooh I can’t write anymore.
Alright-enough shenanigans. Obviously,I was in humor mode. Thanks to Dennis Adamisin and Pete Bergstrom for rolling up their collective sleeves, and trying to put an affordable, task specific product, in to our grubby little-castor oil soaked hands

My understanding is that this Evo is based on the .46 case, not the regular .61 case, for much reduced weight. Magnum/ASP only got theirs out to .53 on the XL case and .52 on the XLS case. They still put out power like a ST .60. So, don't worry about it! H^^ Steve

They actually have a 40 in the case too.....

Hi Geoff. Here's the link to the control line NX 60.
http://www.evolutionengines.com/Products/Default.aspx?ProdID=EVOE0605
It calculates as: 9.726cc (24x21.5 BS)

Yeah, I know. And real boat anchors they are. I sure wish they'd bring the XLS .36's back. They do have a new XLS .25, but as nice as .25's are for sport, they're not quite big enough for competition flying, IMO. H^^ Steve

14oz 40 a boat anchor?? Well.... maybe..... ;D

Sounds a bit like the .36 problem with combat in the 50s when there was the McCoy Sportsman displacing .323 which was supposed to be illegal since the maximum displacement was .35. Problem was the Fox displaced .352.
