Chuck,

I never have seen the RSC 140 in a pattern plane. However, I have the wonderful opportunity to put together a pattern plane is called Abbra in three version. Electric, glow and gas. The glow (mine) uses the OS 160 with perry pump. I have well over 300 flights in this version which is my plane. I fly Master and the OS 160 is powerful enough to move the plane in any wind conditions. This glow version is 9 lbs 15 oz.

The gas versions has the ZDZ 40 engine with carbon pipe. It has plenty of power to do the Master schedule but it is a little sluggish in the up lines compared with the glow version. Down line breaking is great but not too much difference with the glow version. The plane lands a lot heavier than the glow (higher stall speed) but this is not a problem. Base on my experince using this airframe, it is a lot more difficult to make the weight wiht the gasoline engine. Assuming that the gas engine power is linear to the displacement, I will predict that the RSC 1.4 (23 cc) won't have enough power to do the Master schedule unless you get a plane that weights a lot less than 11 lbs. or the RSC 1.4 is turbocharged. Again this is a conclusion base on my experience using the Abbra with gas and glow engines. Your results could change a lot depending on your actual conditions. I saw that ZDZ is coming with a ZDZ 40 F3A that is lighter but I have not seen actual information.

The electric version is 10 lbs 6 oz. I haven't had chance to do the Master schedule Wilt this version. However, we saw this version getting a second place at the Nats last year so there is no problem in regard electric power.

I hope this help.

Regards,

Vicente Bortone
