Yes,it is all about my former work and has nothing to do with my Type X which can finish Oceanview Speedway in 46 seconds.But it is unmodded and can finish the same track in 90 seconds.(These are both computer controlled)It meets the need of the unlimited class.The design is almost same as Type A-Racing,but I did some changes to reduce drag,so it is faster.The changes come from my experience in building Type X,the mod class racing plane,and you can also check it in my post.(the 3.5 version is the fastest,however the 3.2 version is the most reliable)I also worked on some kinda “brilliant” changes like putting a VTOL engine inside but they just didn’t work.1:30 is the best unmodded time I got.Maybe this is the last time I post a Type A,but if I can make it to the day I reach silver,I will post the original racing version again,with silver paint job.
