Ask for advice on modification

[RCSZ]

I'm looking to modify the GAUI X5v2 helicopter into a speed helicopter, intending to use a 4230 brushless motor and a 6S 130A ESC and 550mm rotor, along with adding a full-body canopy and a forward-leaning landing gear. However, lacking experience, I hope to receive some advice😊.

You're probably aware Gaui makes an R5 helicopter specifically for speed. It's a very well engineered Heli, with extremely low frontal area for reduced drag. This is critical for high speed, and of course it is 12S to get the watts required. They show up every once and a while for sale, perhaps a used one would be within your budget, may equal the sum of the parts you'll have to buy for your X5, and you'll go a lot faster.

I know about the GAUI R5 helicopter. I modified the X5 into a speed helicopter. I just like to study the modification. I like the X5v2 very much and I am very curious about the maximum speed it can reach.
