Hi Hyper, Thank you.
The 7.5 is fine. I only run it in Blinky mode but the Worlds can more than handle it. Back in the day I ran 10 triple and 11 double with no problems. I run on a grass track too so I would of thought on Astro with less drag would be fine as well. I have fitted weight also to the front and under servo. There is no lift at all on the straight from mid to top speed and nice balance with corner speed. Just playing with set up at the min and changed the Worlds slightly. Once finished I will post pictures.
