Its not a 3D airplane. Hought power is very big, and with SFGs on it, strong KE is possible.....KE square loops, high alpha KE etc.

Also note, on the spec list, 55g is weight without battery not flying weight. I'm working to get it corrected.

There are three other threads on this plane started. I recommend closing this redundant thread.

After having seen this airplane fly on numerous occasions. The airplane is meant for IMAC style manuvers just like the UMX Beast was meant for. The airplane is very capable of high alpha knife edge.

Mike, I just checked (calculated) the wing loading based on the information listed in the specs I come up with 4.32 and looks like it doesn't include the battery weight either.

Published spec errors are a pet peave of mine. To me it can be something of a deal breaker to see errors like this as it makes me wonder what else might be incorrect or misleading.

On the other hand, the Sbach does look very interesting.

Aglenn,

Thanks for providing that information. Is there a video somewhere?

Couldn't find the weight of the stock battery but have estimated it at around 11 grams (0.39 oz). Adding the battery weight to the listed weight of the airplane gives a AUW of 2.3oz and a resulting wing loading of approximately 5.2oz / sqft. For IMAC style flying this should about nail it.

For those thinking of mods and 3d flying an increase in wing area of around 25% would bring the wing loading back down to around 4oz/sqft. The lighter loading is better for 3d performance and will allow the plane to fly a little slower in an indoor venue but still be ok outdoors in light winds. I'm sure there is a brushless motor capable of hovering the 342....yeah baby...now we're talkin' :-)

There's a bunch of Sbach's out there (in all sizes and materials).

I'm thinking of the indoor season for this one at the end of the year....maybe the price will come down by then :-)

But none made by Parkzone / E-flite. All the foam ones are profile or square bodied, and the wood ones are not parkflyers.

Yea, I'm not a fan of profile planes either. If this can (or be modded to) fly 3D indoors it'd be perfect for me.
