RE: Regarding SP series engines, props and airspeed...

They are made of a black material, Charles. I did nothing to them. They don't seem to be plastic either, I'm not sure what they're made of seems like some kind of graphite or carbon material. I still...

RE: Regarding SP series engines, props and airspeed...

I only have the 4-blade hub, and it'll be hidden inside a P51 spinner so as not to be seen so it's scaleness is irrelevant to me as long as it fits and does the job. I don't know anything about the 3...

RE: Regarding SP series engines, props and airspeed...

You cannot set the blades to 0 pitch (at least not on this 4 blade hub!). 6 degrees pitch is where the stops are (and the lowest possible setting on the guage coinidentally). I made sure the blades...

RE: Regarding SP series engines, props and airspeed...

Arruda, what was your max rpm reading with the APC 15.5 x 12 (4 blade) prop? I couldn't get over 4200 rpm's with this prop even with less than 10 degrees pitch... with the break-in MA 18x12 (2-blade...

RE: Regarding SP series engines, props and airspeed...

Ok here it is on the test stand with the varioProps 4-blade hub and 16.6" diameter blades. I started at 13 degrees of pitch, but it could barely turn 3200 rpm's and sounded like it was really...

RE: Regarding SP series engines, props and airspeed...

I kept messing with it and finally found a spot on the blade about 1/2 inch from the edge of the hub where the plastic pitch guage would clip onto the blade (it's NOT obvious this is where the guage...

Received the package today! After deburring the roots of the blades, I put them in the hub... that pitch square thingy in the middle is a PITA to get all 4 blades inserted into and then put in the...

RE: Regarding SP series engines, props and airspeed...

Looks like ~$114 US Dollars for the 4-blade hub and 4-16.6" diameter prop blades. Not sure on shipping cost though... looks like at least $12 US. Placing international orders always makes me nervous....

RE: Regarding SP series engines, props and airspeed...

Why did you have to make a scale prop? Do you mean for display purposes only, or to fly with in place of the vario prop?

Wow! Almost 15lb plane... that's heavy man! LOL! :eek:

RE: Regarding SP series engines, props and airspeed...

See I didn't think it was that simple either... my gut says there's more to the speed a plane flies than just the pitch of the prop multiplied by the rpm's it turns. Otherwise a 5 inch diameter prop...
