So after about an hour of adjusting connecting rods and moving servo arms I have full travel on the wing sweep, I have it on a 3 position switch for now, I was a little confused at first from watching the assembly video that made it sound like you just snapped the connecting rods on and presto!! … far from the case there was a lot of adjustment to get everything working symmetrical and full travel. That’s what you get from assuming!

Question regarding flying with the ordinance installed or removed.
whats the flight characteristics flying with and without?Comment

I'm a bit dense on this one, so bare with me. Do you mean that on the 80, the wing sweep servos are like retracts? They can't stop in the middle? If that's the case, I guess I don't really know what they'd do if I stopped in the mid-position. I don't recall ever doing it for fear that something weird might happen.
I've just finished swapping one wing on the 64 (a lot simpler than I thought) and being on a slider, I can stop the sweep at any point between in and out, though I don't do it when flying.Comment

Yes, the stock 80 is only in and out, can't stop mid. That's why I asked. The 64 uses regular servos so it can.Comment

So why haven't they made a 70mm one?? Anyone kno?Comment

Well.... I unwittitngly became a test pilot for my maiden of the V2. All checks on controls satisfactory and as she began her take off roll , a slight left drift started . The plane became airborne but it felt very sluggish and difficult to control. At about 15 feet a flat spin was entered and she landed in the grass.
The gear pushed up through the fuselage and the rear fuselage broke cleanly just aft of the turtle deck.
We did the autopsy and..... the right engine was the only one working ! I had not checked during the entire build that both engines ran ! I should have looked and I would have seen that one ESC was dead from the factory!
Well lesson learned !
It nearly flew on one engine , if it had been airborne at the time it may have worked but not from the start of the roll!
I'm over it now, have ordered a new ESC combo and a whole new kit so i will have two of them, one slighly beat up one and a new one!
Hope this only happens to me and not anybody else, Joy of the hobby.Comment

Bummer, that sucks. You'll be ok. Just get back on that horse... er, cat!Fly low, fly fast, turn leftComment

Lucky the break was clean and it looks like I will be able to get it flying again.Comment

Three weeks after I placed an order for V2 wings with AliExpress they tell me they don't have any and are giving a refund.Comment

Some of their stores r good.. some not so.. I stick to the same ones!!Comment

Almost lost my V2 the other day. I carelessly didn't notice the canopy latch was not engaged, even though the rear of the canopy was flush with the fuselage. The canopy separated on takeoff but too late to abort. The jet seemed to be handling ok, so I left the gear down and takeoff flaps extended, turned downwind and planned to land. As I turned base and throttled back to slow down, the jet pitched up and right. I goosed the engines and regained control, but what followed were a series of pretty wild gyrations, with the jet pitching and rolling whenever I tried to slow down. Well past the runway but within the field boundary, I finally got a somewhat stabilized descent going, kept some power on until just before "landing", and plopped it down. Amazingly, the only damage was a broken rod end on one of the wing sweep rods.
I suppose the squirrelly flight was caused by an aft cg shift and whatever aerodynamics were affected by the loss of the large canopy. Anyhow, I have it logged in the "save" category and will definitely remind my old brain to double-check the canopy latch more carefully in the future. Just be advised, this jet does not like to fly without a canopy!

This whole "aft CG" thing is not for everyone. For some, it's a dirt nap waiting to happen. It's great for high alpha work, but even this, is not for everyone. Whatever happened to that old addage: "A forward CG can be flown. An aft CG can be flown once"? Was that just an old wive's tale?Comment

X viper. I do think they land less aggressively on front gear. A small amount say 10 or 15 mm behind.. on grass 4 me anyway. But 40 mm like jon. (2 brother's ). Is to much 4 most. He is very goodComment

The 64mm F-14 does not do an aft CG… The other day in another thread a person said all EDFs have very nose heavy CG points in the manual. I said not all and advised to find a point that each person liked. His reply was, okay 99%…Comment
