looking for 3 or 4 blade props for a dle170cc not sure of the correct size

2 blades size recommended size is 30 x 12 & 32 x 10

also looking for 3 blade props for the beaver

decided to stick a zenoah 80cc twin in the beaver as i need the nose weight

so on the look out for a second-hand one either run or in the box

mag or cdi

sorted

motor and rotors

I wouldn't go to the 32" Richard if you want lots of power, you lose about 700rpm. We blew a piston in the first one we ran because the larger prop was used and we still tried to get 6400rpm out of it.

after having a conversation with the previous owner, i found out the the p47 had a 3w 80cc in it bit under power, after taking advice from a fellow LMA member and previous owner a 120cc with a 4 blade 26 x 12 would be best suited and give a vertical performance as well, that said if i can get hold a 150cc twin, then i can go to 28 -31" props

170cc will be too much and it will torque roll

Hi,
Large scale props by Fiala, expensive but good. For a real scale look try Solo Props in the USA, great scale hubs and ground adjustable pitch, (even more expensive).
I have a Zenoah 80 GT for sale, about 120 10 minute flights in a Ziroli Corsair, replaced it with a Moki 180, amazing!
