Hey Jim, You should not be the one to talk about bias. I think there will be more safe hours out there with an eglass tail spring than there are with steel. I have a glass airplane with a properly

Hi Larry The LS1 cores are quite different to the GU so you can't recut the foam. Anyway, there should be no problem in obtaining fresh foam billets. The plans changes came from QAC and you should

Hello everyone. Recently acquired a Q2 kit here in Colorado that had been listed on ebay. Been spending the last few weeks mulling over the plans, paperwork, and parts. Was wondering if there was the

I also obtained one of those springs from Peter for my bird (thanks, John!), and no, it's neither flying yet, nor for sale. Larry Hamm "SubyQ" JohntenHave wrote:

In my opinion, if QAC had spent half as much energy on ground handling as you guys are arguing, we wouldn't be having this discussion. The planes fly great (except for the GU canard in rain), but

Hi Paul, you have got it in one, it is meant to be weak! You have also recognised that the weakest link with a strengthened tailspring is the tailboom, so you have taken an alternate route of

Jim, Can you remind me again about your tailspring. Is just standard off the shelf solid 4130 x 5/8" steel rod or is it heavy wall tubing, etc.? From what I gather it is solid 4130 steel??? Getting

John, How long is the composite tail spring? I would submit that in a nose-over where-after the Q falls back on it's tail, there would be too much energy for the composite spring to absorb.

Hi Pat, you make a good point - as usual. The issue is that when you reach the overload condition, what breaks? in other words, what is is the failure mode? Next question is how easy is it to fix?

Yup, composite. JOhn

Actually, with a light weight aluminum tail spring, my nose over resulted in an easily fixed (4 layers of glass inside and outside) tail cone buckle and a bent tail spring. Larry Severson Fountain
