I can't actually compare PJS300 and AXI (yet) as I only have experience of the PJS so far but I have to say that it's about as much fun as you can have with your clothes on flying this shockie with it - I imagine it'll be the same for my Blade.

When I first got the shockie flying I had both a 3S Kokam 340 pack and a couple of Etec 1200 2S packs. I tried the 3S with a GWS 9x4.7 and the 2S's with a GWS 10x4.7. My first reaction was that the 3S setup was too wild to be controllable so I spent the first couple of weeks with the 10x4.7 fitted and using just the 2S packs which has been extreme fun and has really honed my reactions to the point where in about thelast twenty flights (fingers crossed in case I jinx it!) I haven't had any attitude I couldn't recover from and it'll do the whole range of wild aerobatics.

So with new found confidence I flew it with the 9x4.7 and lighter 3S pack last night and finally.... NOW I GET IT! This really IS the sweet combination for this plane. I took off from a concrete path pulled to the vertical and continued straight up doing vertical rolls until the plane was so high I couldn't immediately work out it's orientation (not that it matters at that height!).

Even on the 2S packs I can hover (well kind of - as well as I've managed so far). The only problem with the 3S pack I find is that unlike the 2S where I basically have to keep the throttle at 100% to "hover" and just use the left stick for rudder control. With 3S (and lighter pack) this happens at about 1/2 stick so I find that as I use the rudder I am tending to nudge the throttle up/down at the same time which is taking a bit of getting used to (my Tx also has the throttle ratchet removed cos I use it to fly helis too).

The only downside I have with the 3S 340 pack is that it only lasts about five and half minutes and I want MORE! I'm thinking that some 3S 830-850 packs (Apogess/irate/Polyquest) may give the best balance of weight/voltage/capacity.

But to answer your question, yup I think the PJS300SFR (note that's the SFR, not SF I've got!) is certainly a nice substitute until you can get hold of an AXI 2208 (talking of which I notice www.aircraft-world.com have the 2208 in stock so I'm going to order one from there and then I'll be able to make a true comparison with the PJS)
