Hi Lelio,
IMHO the airframe of Acrobipe is much too heavy for Vapor brick (empty is over 1oz)
From my experience this model flies fine on IPS50 or 12 mm Feigao with 4-5g two servos. You can shed some weight by using smaller batery (like 2cell 340) to have fine flying indoor model (3-4oz) or use 2 cel 730 and fly outside in pretty much any flyable wind conditions (5.5oz). Much more info in my previous posts.
Good luck, Janusz

Janusz, I'm still haven't gotten around to finishing mine. But I'm glad you monitor this thread. I'll be needing to get cg adjustments on your previous posts.

Oy Vey... CG... as I remember... 1/8-1/4 up front of the rear edge of the outer wing strout.... just support the model by your fingertips on the ends of glued to the upper wing surfaces of the outer strouts... I hope that I am clear here. Keep it rather nose heavy for the maiden than move slightly to the back by moving the batery. When you happy with the CG make sure to block the batery in the position to avoid shifting...small blocks of foam and drop of hot glue should do the trick...

L, If you use the Vapor brick you should either have plenty of power to haul the acro around with our lighten up the fuselage. I would do both. This plane flies absolutely fantastic!!! And if you lighten it up even more, look out!

anyone still flying these? i'm beginning to start on my last one from the "luftcloset" and need info on a motor for it. cannot find GWS IPS-50 motors and previous experience tells me the stock motor won't cut it. i do have an old 180 motor that may work. not going BL on it as I don't have a brushless esc and am doing it "on the cheap". btw, these make neat electric CL models, as long as you don't try and stunt them!

I still have one that I can fly. I originally put a medusa motor in it, but settled for a GWS ips 50xc motor. And yes, you can stunt them.

I still have one too. I started with an IPS, then switched to Medusa, then put in a Feigao, as Medusa was needed for another project.

stunt was meant in the control line vernacular.

my old zero time mabuchi fk-180 motor produces a lot of thrust with 7.2v so after 17 years the motor has found a home. pics to come.....

Hobby Lobby has one on sale

23.99 now but still a scoop... you can have a LOT of fun for 24 bucks

Any thoughts on putting the motor and brick from my parkzone p-51 into one of these with ailerons??

Oh, and not in stock at hobby lobby. Any other sources??

IMHO the airframe is much to heavy for Parkzone brick.
12mm Feigao on 2 cells with aileron , elevator control gives you a perfect little flier. I miss mine... should build another one. Nothing flies like little Acro!

Thanks. That's what I was needing.
