Hi everyone,

Here is another SPAD build log
SPAN : 48"
CHORD: 9"
MATERIAL : 3MM CORRO

The earlier V Tail I built was not a good flier (crashed a lot) but had me read a lot about v-tails, so attempting another build, this time fully out of corro.
power plant would be a DYS D3536 1000kv coupled with a 10*7

I want to build something like this

Thankyou Sanjay sir. fuselage and tail and assembly. ditched the tail boom and vtail. It looks like a spadstick except for the rudder.

Crashed the one in the pics above on last Saturday, built a lookalike this week.
The fuse is 30inches long and the wing has the same dimensions. It looks better now I think.

@manu,

Congratulations. Flies well.
You need more airspeed to roll safely!

Thankyou Sir, It was a 9*7 on 4s, it was flying at around 30% throttle, plus the pilot lost orientation as it was a bit dark but somehow he managed to save it during the roll

It has an autopilot in it.Flew it today on stabilize mode , flies pretty stable.

Very smooth.
But some overcontrol in turns?

Sir, there is automatic rudder assistance to avoid adverse yaw when a roll input is given (the autopilot does it) even if we haven't given any yaw input from the transmitter , may be it's because of that.

Very well build Manuji. SPAD are always great to fly and watch.
