I just got an Integral. How did you get to 10lb 8oz? I thought these  things 
were coming out at under 10lb for 2-stroke engines/OS?
 
I'm still deliberating about going to YS for this plane but after the  
glowing report about 9.5lb performane I am tempted to stick to the reliable  OS.

 
Colin, without the additional weight on the fire wall the integral finished  
at 9 lb 10 oz
I added 9 oz of lead on the fire wall to bring the CG forward to my taste.  I 
felt I was chasing the model instead of flying it  I added heavier  silicone 
couplers because the airflow through the tunnel was not enough to keep  the 
silicone cool enough. Teflon couplers would make it much lighter. I added  
baffles around the engine to keep the cylinder head cooler. I am running an  OS 
1.40 and an Aeroslave pipe. Even with the extra weight I have plenty of power  to 
spare. I do suggest trying to use a push rod system for the elevator to get  
the weight out of the Stab. If I move the servos out of the Stab I will not  
need the extra 9 oz.
 
It is a very nice model and I am very happy with it overall. I am not happy  
with the servos in the stab.
 
Carl
