I am new to rc aircraft i have a seagull arising star and an irvine 46 engine, which prop is best for this setup?

11x6, 11x7 apc would be my recomendation

11x5 or 11x6 Master Airscrew. Will keep the plane slower and these props are less expensive so you can keep a few spares... you will need them.

I agree on the Master Airscrew props. Not as efficient as the APC's but last much longer because they don't damage as easily from minor ground contact. Better in a training environment IMO.

thanks, i am still at the early stages, and this is all more in depth and interesting than ever imagined

Definitely stay away from wood props at all costs. They break extremely easy.

which material props should i concentrate on at this stage. i will probably buy the master airscrew as recomended

Once you have been flying enough you can tell the difference, try several different brands and sizes (around those recommended) of props. Different airplanes and engines do better on different props. The ones which don't work as well on your airplane now will probably be the best on another airplane/engine.

11x5 Master Airscrew well work will for you.

I'd recommend the [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXGAK9&P=ML]Hobbico 11 X 5 NextStar Propellers[/link] seem to work great on .46 engines on trainers, and they are only $1.99 each at Tower. They are also very rugged.

I THINK YOU WILL LIKE THE PERFORMANCE OF A 11X 5 MAS PROP. GIVES FAIR POWER HOOKUP WITH GOOD BRAKES, ON FINNAL APPROCHE! WILL ALSO SLOW YOU NICE IN A DIVE! IF YOU BACK OFF THE THROTTLE.[&o]I WISH I COULD SPELLL BETER.

We're suggesting something like this or a slightly different pitch.

great stuff. i am going tomorrow to buy stuff to make up a field flight boxso will stock up on a few props

You may be supprised by the MAS prop, I bought 3 when I started , and still have all 3, and I soloed in July, I did " scratch " one though..
