Wrote the letter of intent to the MD-RA

Wrote the letter of intent to the MD-RA. In the letter of intent, I have set the Max takeoff weight (gross weight) at 1800lbs. After reading into the forums on weight and cg measurements. I see that some folks increase gross weight rating and extra 100 lbs or so. I thought about doing this....but it would mean that I have to correct and resend in my letter of intent. Also I understand that flight testing with the increased weight is a bit of a pain as you need to prove that the increase in weight is still safe. I have made up my mind that I will stick with the 1800lb rating and concentrate on building a light RV (The plane is supposed to fly much better when light).
