delta force votrex hydro 22 question

[netik racing]

so i got a dfv 22 off ebay for $100 with hardware almost ready to run...

After a few weeks of running the small 540 in it got a bit sick of the slow speed's and the cooking motor...

So upgraded both the motor and and esc the motor is a 2200kv leopard and a 180amp seaking esc...

Im running a 40mm 3 blade propshop prop
Its good for about 90kph and im happy at that..

The question i have is what sort of turn fin should i use and what size should it be and should it be curved or straight?????

If anybody has already put one on there hulll could you post some pics up so i know what im doing...

This is only my second hydro if you can count a small bolt as a REAL hydro

Sizing for the turn fin should be somewhere along the lines of 2 inches by 1-1/2 inches. A typical Hydro turn fin curves towards the hull. The best mounting location on that hull is the rear vertical face on the right hand front sponson. You would require a 90 degree bracket in addition to the turn fin.
