i glued it on with silicone glue

Do I need to glue the handle on? I already went to 108% on the pin and its still a little loose, any suggestions?

Hi, could you post a video of this in action? Thanks!

Hi,nice design
Could you upload a version of the cylinder block without the fins it would be easier to print and also quicker.

In order for the timing to be uniform, a four stroke radial engine needs to have an odd number of cylinders in each row. The only real radial engines that you will find with an even number of cylinders are those that have multiple rows of cylinders - each row having an odd number of cylinders.

A two stroke radial engine could have an even number of cylinders but I don't know of any real world examples.

I did not know that, thanks for the information! I will have to study more about radial engines.

Really nice model, I'd like to see an odd numbered amount of pistons though, as stated by ModelStation. (preferably 7 cylinders)
The reason for this odd number of cylinders is the firing order, which skips one cylinder every time.
As such, a 7 cylinder radial has the firing sequence: 1,3,5,2,4,6 and back to 1, where the numbers represent the cylinders.
An 8 cylinder radial would have the sequence: 1,3,5,7 and back to 1, thus skipping the even numbered cylinders.

Thanks for explaining the reason, I was wondering what the reasoning was behind this.
