I fly mine every weekend, usually get 7 or 8 flights on it over the 2 days. Well over 30 flights all up.
I rarely nose over any more, I find it noses over more so when taxiing down wind, too slow, and more so with a full tank.
Keeping the elevator stick full down while taxiing helps a lot.
I have been thinking of moving the tank back over CG, this should stop nose overs even more.

I balanced mine right on the recommended CG, however I have since taken the cowling off. The plane still flys nose heavy, having the fuel tank up front wouldn't be helping. I have my battery as far back as I can with out making some mods, so if I move the tank back I will look at putting it back further.
As is I like the way it flys, but I do need a lot of up elevator when inverted. KE is crap, flat spins are crap, 3D is no existent, but I love flying it. It handles wind very well, and once the landing gear platform has been re-glued it is one tough little plane.
I have hit the ground hard a few times, tip stalled and pancaked for around 5 foot, run way rash on one wing tip from landing in Strong cross winds, but its still solid as new.

It does drop very quick when you cut the throttle, but you get use to it, every plane is different. I still feel it lands well, I some times fly it is with a bit of speed, other times I land with only a short roll out, either way is fine. Just be aware that it can tip stall if you wipe off too much speed.
One of the things I found when going from a 14x4W prop to a 13x6, it doesn't put the breaks on as hard when you pull the throttle stick back.

The colour paint ball splats are a nice look, but they are a pain. I am often ironing the tips back down and catching them on my cleaning cloth.

Chris, its sounds to me like you are coming in a bit too slow, the tip has stalled and you haven't had enough hight to gain air speed to pull it out. Having full elevator would only make it harder to pull out of a stall.
I find keeping a little throttle on and lowering altitude using the throttle (and using down elevator stick) rather than cutting the throttle and letting it glide in prevents this type of problem with heavier planed like this one. Moving th CG back a bit might also help, but the more you go back the more chance of a wing dropping.

Lover your work ProScaleRc, looks great!

Any one got a fix for covering lifting and bubbling ?
It craps me off have the covering bubble every week or so.
