My Feedback: (14)
Well I cant wait to start my A-10 but i promised myself I would get my CARF P51 done first. But since I’m in hotels with some time I figured I’d cheat a little. If anyone would like a scale GAU8 Avenger SLA printed, let me know! SLA= invisible layer lines. I can print any scale!
More high quality Addons are in the making, stay tuned!

Well, it looks like my nacelles don't taper down nearly as much as yours, which are probably more scale. Not sure what difference that would make but maybe it does. The higher location of the pipe on mine may also have something to do with it. Anyhow, congrats on the additional flights. It's looking good!

It would be interesting to see someone (Lavi Rider?) put pitch axis thrust tubes on their A-10, adjustable in small increments on a rotary dial. It could be test flown to find the angle that cancels out any pitching moment with thrust. A regular, fixed tailpipe could then be made to match that angle. I think the tailpipe/thrust angle is the most likely cause (and fix) of the pitching issue.

Hi
I think you can get it pretty well dialed for a given speed envelope, but not for the whole speed envelope, due to the engine thrust line is off to the wing line.
I have seen a Mibo A10 flying with no angle installed in the turbines and pipes and the pitch/elevator was quite noticeable. After that, he changed it and got better, but will not be perfect if you increase it more
The 7- 8º, work as the best compromise for medium to high speeds, but at low speed passes, be aware or it will bite you. Gets worse with flaps down
My guess is if its increased more it will climb at medium to high speed, but would be neutral at low speed

There may be something different with the current generation of MIBO A-10's that makes them more thrust/pitch sensitive, as you suggest. In-flight testing, with small increment thrust angle changes, would be the best way to find out, IMHO.

I would agree with you if I did not have over 160 flights with my MIBO A-10 with absolutely no thrust induced pitching moment at any airspeed and power setting. I fly mine pretty aggressively and in a wide speed envelope (as you can see in this video: https://www.youtube.com/watch?v=_cOGKbr9TQk&t=5s), and I'm sure I would have noticed.

Great flying Craig.
I have arround 15h flight time on my A10. Mine is an early gen A10. Maybe in the latest versions they change wing or stab incidence or improve something to reduce the pitch elevator issue. Would doubt about it, but I maybe wrong...I remember old flyeagle A10 versions woudn't take off because they had 0º incidence in the stab.
Would be nice to know your installed turbines thrust angles any way. Mine is arround 8ª. CG have an influence on this behaviour as well
When making a low and slow pass at arround a bit more than 1/3 throtle and full flaps, when exiting this low pass, I have to be very carefull with throtle management, otherwise nose comes down, when power is increased abruptaly
Next flight you might try that and see what I mean

Nuno

Nice shots Rav !
Craig, I have one question for you. I heard stories about the Hawg doing a weird "dance" when arriving on target to avoid enemy fires. Not flying in straight line. I never seen it on video myself but I wonder if this is true or not ?

To avoid exposure, one technique the A-10 (and other fighters) use is a “pop-up” maneuver. I never heard it referred to as a “dance”, but the idea is to stay low (terrain masking), then pull up sharply (pop-up), roll inverted, pull down into a dive and then roll upright, pointed at the target. Almost like a straight-ahead ½ Cuban 8. Another technique involves attacking from an angle and staying in a turn (called a "curvilinear" approach), and rolling out just long enough to fire. Sometimes they use a combination of both methods.
In either case, after firing, A-10’s will typically pull away hard to avoid flying over the target and turn aggressively every few seconds (known as “jinking”), to spoil the aim of any would-be gunners. I actually try to replicate these maneuvers with my A-10 when the flying field and pattern allow it.

Thanks for these explanations.
I will try the "pop up" next time ... sounds like an awesome maneuver !!!!
I had the chance to watch a great show put by a couple of A-10's at Reno races. They did all sort of attack and evasive maneuvers with actual firing at dummy tanks.
I always try to emulate that flight
