Received mine last Thursday, and started build on Friday. Build was going great and loving it so far then got to bag R and it was not there Bags S T and U is not there either but V the wing bag is there! I have been watching the ET48 in the Michigan state champ series and between them and this thread decided to pull the trigger, so glad I did. Now just waiting on a reply from Tekno on my missing bags so I can run this thing as I feel like a kid on Christmas Eve just waiting to rip into the packages
