Welcome to the forum John
Your English is better than my Greek so do not worry about it
The springer propeller should not be bigger than 38mm (40mm if no one measures it
), I do not think a 90mm prop would even fit under a standard springer. The rudder can only be a maximum of 100 square millimetres, I do not know what size Odin had fitted, but with a 90mm prop it will not be too small.
I do not know the comparison between motors but the biggest should be a 550, with a maximum voltage of 7.2volts. If you want to use the parts you have then you will need to scale up a standard springer and make a super springer.
Hope this helps
