RE: DLE 35RA going to 3 blade prop
If the plane is over 14 lbs I would just use a two blade prop.
MTK the Mej props are not as scale looking on the ground. in the air now ones how many blades you have.
even though my tigercat will be around 13-14 lbs per engine i would have no issues flying it on the 35 and that prop.
MTK I dont think the 33 will spin the Beila 18x10 that well. If there is one at the field this weekend i will throw it on and see what it does.
I know you have a pipe on yours but most warbrids dont have the room for a tuned pipe.
OP, there other props that are the most scale and they are the "Solo" props and are ground adjustable.
