With the lighter tails and further aft CG, you may see the F3B weights even lower....

It will be interesting to see what happens.

Tom K has the one that I assembled, and I'm eager to see where he places the CG, etc.

Arh T,
The "Legendary" John Philips has a Toba over here in blighty.
I would have to say that its a stiff model.
Pencil for a fuse which makes getting any weight in her a real disadvantage.
He only test flew it a couple of weeks ago and I would have to say that it performs F3B tasks very well.
His comes out at 2.3kgs and launches really well.
The wing looks like a modded MH32 section and the wing plan view looks very cobra-ish.
Obviously its a whole lot thinner then a cobra wing.
Speed wise there is some flex in the wings during the turns, but it doing some 19 seconds runs and its not really tuned yet.
I think JP is actually quite happy with the model.
I know I would be if I paid the same for one as JP did.
I have no idea where his settings are.

TTFN.
Nice looking model.

Jon

I flew it again at noon yesterday, I started tunning the snap flap.
I identied a good level at middle stick, so I worked on a curve as the entry in turns was better without snap than with snap, and on the max value as it was slowing down elevator fully pulled.
I reduced the snap at the beginning of elevator travel, and played a bit with the max value.it was good from middle to max travel, but still not fantastic at the beginning.
I left it like this anyway as I still needed to work on the reflex, and would diminish the flap level for a given elevator throw.
I ended up with around 1mm reflex, and a glider that was accelerating a lot in energy management, although I was only carrying 500g.

with the current setting, the glider has a lot of grip in turns and comes out of turns like a bullet: I wasn't expecting such good flying caracteristic for such a low price!

I will measure all the throws and post them here: they are quite a good start for anyone owning a Toba.

Cedric,

PS: I filmed all the sequence of tunning, so you can see the effect of all the different settings.

Cedric are you going to post the vid of your tuning of the Toba?
I hope you do..

I'm hoping that Tom and Dave and Kyle get time to put the Toba I assembled through her paces soon, and report their findings back.
Tom has obviously been busy (in SA!) and Dave is a Father with two young sons, and Kyle has been very focused on the upcoming F3F WC.
Hopefully soon!

I have the Toba all setup now. Head to head comparisons with Fosas, FS4s, and Precisions...

Give it some Mumbo

Looking forward to the road test David.

Give it some mumbo up the line in a breeze.

By all reports it's 300g more than the latest F3B ships; if they (RCRCM) can hit 2100g un-ballasted AUW then it might be worth a punt for F3B otherwise it'll be relegated to F3F / Sport Sloper.

It's heavy. I picked one up for duration and asked the guy if he had forgotten to take ballast out.

The one David has I believe is about 79oz; if they could shed some weight from the tail panels, they could drop a good amount from the AUW of the plane.
The fuse tail moment is not real long, and the nose moment generous. The fuse is pretty light.
The wings could also stand to shed a bit of weight, especially at the tips.

These are just my opinions, I look forward to hearing what David thinks of the Toba.

I'll try and throughnitmon a scale, my review will come in 2 parts

1- Build quality and layout

2- How it flies (the most important)

79 ounces isn't too heavy. I would day the one I picked up was heavier than that though. I would guess about 2.4kg. Not my model to weigh though.

Of course how you make/install the battery pack can make a lot of difference to how much nose lead you need.

I'm looking forward to Dave and TK's review of the model....
I heard they gave it a good air beating last weekend, and it performed pretty well.

Standing by.

On the AUW of the model, in my experience this model stays up pretty easily at the weight it is.
I'm more concerned that it could fly even better if the extremeties were a little lighter, even if the AUW stayed the same.

I built mine with the standard pushrods & have had to add quite a bit lead to balance it. I haven`t weighed it . Even with my limited skills on the sticks it thermals very well..
I have teflon tubes & carbon rods to redo the tail control runs & hopefully it will be even better..
Come on Dave post your reviews :-)

Ian-
The best thing you could do is to make new bagged tail panels that weigh much less. I would think it would be easy to make some that weigh about 35g each and are bullet proof (flying at least).
That would be 30g from the tail and with the rods, more like 40-45g.
Then you'd likely be taking a good chunck of lead out of the nose (75-100g?).
Its not the total weight that hurts you, IMO, its the ends of the plane.

PLEASE DO post what the weight savings is by swapping to the snakes in the tubes. Since I didn't do it as a retrofit, I can only guess what it saved me on weight. Make sure to balance before the modification is started, and after.
Thanks!

R,
