I have a 40cc gas and have busted a prop [&o]. Does anyone Know where there are good deals or bulk deals on propellors, I use a 20 x 8 and they get expensive at that size.. Thanks for any info......

Your choice is easy.... Cheap. Good. Quality.
Pick one.
If you don't care much about having to do a LOT of balance work, and you want "cheap".... TopFlite "Power Props" on Tower are about the cheapest out there. They really are crap props, though.
Slightly better, slightly more expensive, and "less" crappy are the Master Airscrew wood blades....

Good performance, and better quality ends up about $1.25 per inch.... average. Lots of choices there....

Join towers super saver club now for 19.95 save 10.00. Wait till they have 30.00 off a 150.00 purchase, then get 150.00 in props and free shipping. TF props work good if you get one size larger and cut them down to fit your engine. Then you get a strong thick cheap prop. MA props are made from junk wood and are almost imposible to ballance. Have 2 free for anyone who comes and gets them. 22x10

Well a cheap prop = cheap performance.

Personally I would look at where the compression stroke is and where you have the prop set. If when the engine dies and the prop is at 12 and 6 then you are asking for a broken prop on a dead stick landing.

I would spend a weekend doing touch and gos to improve your landings and keep with the nicer props. Your flying will be more enjoyable and your wallet will stay full (till your next plane purchase)

yes, stay away from the TopFlite props if possible. You can buy the NX/JXF/TBM/WildHare/BME (same prop, different logo) props at several places. I bought a couple from www.valleyviewrc.com , but Troy Built Models also sells them. My 22x8 is about $25 shipped. www.troybuiltmodels.com sells the 20x8 you are looking for, and the price is $19 plus shipping.

This price is about the same as the TopFlite prop, but trust me this TBM/JXF prop is significantly better. The blades don't flex and flatten out under load.

Brett -- I'd lost that ValleyView link.... thanks! Just ordered a couple spares, his prices are about the best. The JXF is "supposed" to be same-same as Xoar. We shall see....

If you keep striking the prop cheap props will be the least of your worries []
