WFH Ok 10 flights.. I'm not sure if my clamp is too big but I can't tighten the wing bolts without stripping the treads off or bbreaking the bolt head so I need to look into plan B. Thanks for responding.
What's up Chic man see what almost happen to this brand new bird?...almost cartwheel it smh.

tighten the clamps without wings and tail in them first then loosen them and insert wings and tail it will make a heck of a difference in holding power once they have compressed past the needed point.

Gg with vector thrust
Can anyone running Vector thrust share pictures of their setup? I just checked the CG on my predator with VT using the tool to check the CG and needs about 800gr (1,7lb) on the nose to balance! I have all the batteries forward, not much I can move towards the nose..
I checked the CG with zero fuel

I 've moved the smoke pump forward and relocated all the equipment. Now with full uat and about 1in of fuel I need about 8oz or 220gr to balance using the provided tool.
Any input from the guys running Vector thrust is appreciated

I just finish my predator 2.2 took me 5 days to complete, very easy to put together. Take it to the field yesterday to do some highspeed taxi test before refuel to maiden the bird. What happen next...well watch the video.

My question is how many guys using this new style wing clamp system without any problem?
Check the pinch clamps are not upside down!! We had one like this

Yes on a friends Predator one clamp was upside down which meant the threaded side was at the top, so no matter how tight you do it up its not pulling the clamp together!!

Well my wing clamp was installed correctly with the treaded side to the bottom...it did tighten up ok. I only noticed this problem during a high speed taxi test and have to over correct as the jet veered to edge of the runway. As seen in the video.
Anyway maiden flight went very well..thank guys

I'd be cautious of where you locate the screw and wooden dowel. On pattern planes, the wing hold down screws are at the end of the wing tube and not near the fuse interface. There have been many incidents where the wing tube failed at the screw threads. If the wing tube threads are at the end of the tube, less risk of loosing a wing in flight.

I know it's also sitting a little to the left, it's not bolted in yet. Obviously I can't really lower it without completely redoing the motor mount plate, and interestingly the tail cone is bolted to the same plate, so you'd think they'd be automatically centered, height wise.
So, tear into the motor mount plate, raise the bell opening of the pipe to center it(and consequently possibly affect thrust angle), or don't worry about it??

Adjsut the pipe in both way......thrust can be trim...unlike a prop plane where there’s a lot of side effect...on jet I don’t find that, your not talking about a big move here, the danger is a hot spot.
