I recently got a World Models Ultimate 30 from an auction. It came with a Magnum .52 4 stroke. I was looking for additional info on these bipes and came across your posts. I was hoping you could give me some additional info. Here it goes:

1. What prop and tach reading would you recommend for this engine?

2. What is the balance point for this bipe.

3. Do you know where I can get a cowl for this bipe?

Thanks in advance

Here are some pics below:
