officially on board, been a rc modeller for 40+years, just ordered my first 1/4 scale plane . based on various post that I have read here, I bought a BUSA pup. I have one ? if you don't mind. I am a big OS engine fan, that was all I ran in my hel's and I am looking at the GT33 gas engine. In the post on the pup it seems based on engine choice, you might have to add nose weight. I was thinking with the carb rear mounted that engine setup might not require any nose weight. I know this motor has a high price, but if it helps with weight/balance, i'm ok with the price. please don't hesitate to recommend another route if I am going in the wrong direction. I never turn down free advise.

Welcome aboard Tom. I'm glad you found us. As you already know there is a wealth of information and assistance within this forum. I recommend you become a site supporter so you can start a build thread. We would like to watch your pup go together and it will enable you to tap into our talent pool in case you need help.

Again,welcome to RCSB!

what Ron said, and here is a link to the program http://www.rcscalebuilder.com/page_display.asp?pid=5

You will enjoy yourself here, make lots of new friends and get LOTS of support for your build.

Thanks for the warm welcome, i live in Midlothian Va. if anyone is close please speak up. I also became a site supporter as well  also did not get much feed back about using rear mounted carb motors. it seems like it would help offset the large amounts of weight that is added to the nose. does it interfere with cowl. i ordered the alum. cowl with my pup, so if it does i'm not going to order my motor w/rear carb. Oh 74Ranch is one of my best buddies, it is a 74 Ranchero, tried to use a pic in my avtar but it said it was to big, don't get because I use the same pic on other forums maybe now that I'm a site supporter it might let me.

thanks again, glad to be on board, reading all the Pup builds i can find!

Tom
