Thanks to my daughter for dealing with the mosquitoes while recording this video. A little distracting to hover when the little buggers are going after your face and legs.

Would it be possible that if the prop hang was steady enough you'd create a ghostly image of the plane surrounded by the traces from the rolling harrier circuit?
Yeah. get one of your mates to give it shot (pun intended ) You never know until you try!

Ron my thoughts are with you, Polly and of course Belle. Wishing her a speedy recovery.

I know how you feel, I'm a gibbering wreck anytime we have lost a pet and each time I say no more. We now have a Rhodesian Ridge Back, an Egyptian Mau and a Bengal.

Q - Trimming method for 3D foamies?

This has probably been asked many times before, but 5 searches later I'm none the wiser so here goes...

I'm a fairly expereinced pilot but a total newbie to 3D foamies (I mostly fly slope and thermal soarers). I've just built and test flown the 32" Twisted Sbach; it seemed to go great, though when you're used to nudging a sloper round the sky with tiny movements for max efficiency those huge control surfaces take some getting used to! Anyway, my question is this... how do you go about trimming a 3D foamie for optimal aerobatic performance?

I suppose the three main variables (other than rates, which I guess are more personal choice) are CG, downthrust and sidethrust, correct? Mine doesn't seem to need any sidethrust - it tracks straight at all power settings with no rudder or aileron trim - but it climbs strongly hands off at full power and seems to nosedive somewhat at power settings less than 1/3. On a glider I know the tests to do and in what order to optimse CG, but I'm pretty clueless when it comes to a powered model with a flat plate airfoil.

Is this just expected behaviour, or is there a CG/downthrust correction I need to make? If so, are there any tests (i.e. trim for level flight at half power then carry out xyz manouvre etc) that can tell me the changes required? Any help you can give is much appreciated - many thanks!

Matt

I think you want to do most of your tweaking with CG and not with thrust angles. I'd move your CG back to the point where it flies the same upside down as it does right side up - without diving or ballooning. Also don't use any elevator trim which isn't needed in the same amount and in the same direction for both upside down and right side up. Hopefully you'll have no trim at all set up. Just my opinions.

In my experience this mean that your CG is to far forward. You can confirm that by flying inverted. If it dives when upside down the CG needs to be moved back.

Another thing that is important on this small planes is lateral balance. If the plane roll out of a fairly tight outside loop, one wing is heavier than the other. Try to balance with the battery and if it is not sufficent, use a small screw as a weight in the lighter wingtip.
With good lateral balance will it fly very precise through all manoeuvres.

Thanks gents - my gut feel was that the CG was too far fwd, but I didn't have the experience with this type of bird to be certain. Time to dig out a 7g weight and go testing!

Good luck to Belle, it breaks my heart when a beloved dog is ailing. My little Doxy, George is getting pretty old and the thought of him being gone is a tough one. My prayers for you and yours.

Ron,

I hope for speedy revovery for Bella and i hope she was many wags left in that tail. We lost our dog of 15 years about 3 months ago, I still tear up when thinking of her. She was a true friend. and is missed.

Ron, hope your dog pulls through, I know what its like to go through that. It must be hard not being able to be right there with her. I'm hoping for the best.


I got out again and played with the long exposure. This time set it to 30 seconds, F4, and played around with the ISO, got down to about 250 and was happy with it there.

It would be really cool to see what this would look like with someone who actually knew how to fly these things.

Ok I'm done posting swirly blue photos. Night flying is too much fun.

About the new model with information coming out "soon," would this happen to also be the same one I'm saving this micro gear for? If not, any word if info on that can be expected in the near future?
