Title: Average Motor Size cc
Post by: joecnc2006 on October 20, 2015, 11:55:40 AM
What is the size people are building, I am looking at 92mm x 82mm standard cam, I imagine I will get about 38-40 hp?

What do you put in your motor's - specs, carbs etc.
Would like to get a feel for this, and its performance, hard to tell in videos of people just flying around.

btw: going to start building the LEXL.

Considering you are going to have the same amount of money in your engine if not more, by building it yourself or buying it from Scott Cassler --just buy it from Scott Cassler.

This is saying nothing of the time and headache you will be saving.  

I can guarantee you I have more money in my engine than Scott charges for his 45 hp, and we have had several very happy Eaglers running the Cassler 45.

Building an Eagle is 2 projects, the airplane and the engine.

Do yourself a favor...  Build a nice XL, then buy the baddest ass engine you can afford to put on it and fly happily ever after.  (https://ssl.gstatic.com/mail/emoji/5/48px/emoji_u1f609.png)

A member here that put a 45 HP on his XL told me that the 37 HP would be a better choice for my XL because of my weight (150lb.) He said it would fly great and the 37 HP engine is smoother than the 45HP engine.
So depending on the pilot weight might make a difference on which engine you choose. Scott Cassler will build my engine for me when the time comes.

Dan.I think you miss the point..There is no doubt that a person who has built hundreds of these engines knows more about them than the rest of us,but the whole object of building for some of us is the satisfaction of completing the plane and the experience obtained,Starting up a new engine after building it yourself is akin to the feeling one gets on that first flight.Some builders have to learn to weld prior to building so what is the difference in having to learn to build an engine,Help is readilly available to build these engines and Scott will supply all the special parts and give his advice willingly as has been demonstrated in this group.,If all you want to do is fly the eagle go ahead and purchase as many finished parts as you can afford but if you want the most satisfaction out of this project,go ahead and build your own engine,

Rex, well said, But I can see Dan point of view also, If I had a good chunk of change at once
But for me being able to buy the parts slowly as I build the engine is more budget friendly (easier to eat an elephant one bite at a time), even if it cost a little more I will not feel it as bad. And I'm the type who would rather design and build instead of purchase. this is true in all my projects and my CNC Machines. So I was just asking what people put in their particular motor and its performance and what they might have done differently. I have seen topics like this here but they seem to die off without any good data.

Scott has the cylinders (stroker nickies) you want, balancing you want, the rocker shaft work you want, and the thrust bearing setup you want.  He can cut the case if you want.

Get with him early on the crankshaft, there are considerations on the cut end regarding the thrust bearing and mag drive.

He should write a manual and sell kits, like Steve Bennet did.  I suspect he is too busy supplying built engines.  :emoji_u1f62f:

Builders who want to build their engine from scratch need the info from the attachment in this post:

Nice read, I will be having all new parts and from same source, he has been doing vw for over 40 years, and knows all about the half VW, he is machining and clearing case for the stroke crank, which he is also providing, the crank will be magnaflux'd also. He also knows leonrd, and also supplied parts to those who build and sale the full and half motors for sale (as mentioned above). Building a VW engine is pretty simple and straight forward, If you have rebuilt other engines you can be confident in a half VW build with the correct parts provided (New Parts). I will not be using old engine as a donor, do not want to trust used parts, and parts not from a reliable/known source.
