Default What prop for my rigger?

Hi everyone.

Im currently in the process of building a rigger that will house a thunder tiger .21 pullstart enigine. Being quite new to the hobby i have never had to pick a propeller which i think will go good with the engine. I know that with riggers i will need a lift prop?
can you guys help me out here. If you need more specs on my boat please ask.
Thanks

Since I am unfamiliar with pullstart engines, I am still assuming this motor has a tuned pipe on it. Can you get abc props there? What is the weight of your hydro? What hull are you building or is it a scratch built. If you can answer these questions I would be glad to try to help from that point. Ken

Default specs

yes the engine has a tuned pipe. it is scratch built just a very basic design, no special ride pads or anything. The pullstart may just take away a tiny bit off the max revs and a tiny bit of horsepower.
The whole boat should weight about 900g to a kilo with a full tank of fuel.
I looked around on the net for ABC props but have not found anything but if you can could you please post some equivalent props just incase i cant purchase one or the other or 'here'.

Thanks alot Ken

the easy up prop would be an octura 1445, this is easy to pull for most 21s, the octura 1450 while much quicker some people have to cut it down or depitch it to pull the prop. if you find abc props available to you. the h-5 or h-6 will work well. abcprops.com or you can order on the web grimracer.com. hope this helps

On my 20 rigger I use the H10, mod.x445 and a mod x442. The best thing for the scratch built hulls is the painful trial and error. I recomend starting with a smaller prop. x440 or the H4
