Well guys i got my alpha 40 started today about to go to the field and maybe fly for my first time. well i was messin around taxin and broke my prop my ? is do i have to buy back the same prop or could i get any kind of prop and put on it

well seeing as how you broke it taxing I would use a 10x6 and get some bigger wheels, i have a Superstar with 3 1/4 inch wheels, it helps alot, aspetialy in high grass

when taxing give it up elevator

what size is on them and do i need another 3 blade or a 2blade and whats a good brand

if u buy a 2 blade, you will need a new spinner

coud u guys tell me another good 3 blade to put on it or where i could get the same one that came on it

Master Airscrew is a good brand
Go to your local hobby shop

Master Airscrews are a great training prop. i learned on a master airscrew, and then my instructer told me to switch to this grey prop he gave me. master airscrews are strong as heck, but not very efficient. but if u are just starting out, a master airscrew willl work greeaat!

will it hurt to start my engine with jus 2 of the 3 blades i just want to listen to it run but i dot want to start it with only 2 of the blades on there if it will hurt the engine

DO NOT start it with any damage to a prop! Not only could you throw another piece of prop and hurt yourself or someone else, but the vibration with destroy your engine and probably you plane as well!

TN is right. Don't try to start it with a broken prop.

I would recommend getting a 2-blade 10 x 6 prop, and a new spinner. You'll probably break a few more props as time goes by, and 2-blades are easier and cheaper to replace.

Go back to where you got it and buy the same 3 blade prop, or.....get a black Master Airscrew 10X6 (almost too small but will work).

Minn is right. Get a new spinner and some spare props. I would suggest a coupla 10-6 and 11-5 Master airscrew black plastic ones. That should work good with a 40 engine. If you have a 46 try 1" bigger in prop with the same pitch. That should get you going again. It is nice to have a few choices to try. so don't be afraid to buy a few different sizes and brands. It is nice to have a few to experiment with untill you find one you like. If you are above 3000' altitude I would go with the 11-5 first. Good luck.
