best 3 blade prop for RXT w/ rude 1 etc..?
I'm wondering if those with experience think the 15/19r 3 blade from the Riva RXP stage III kit is a good match for an RXT with rude1 charger, ext. IC etc..
stock ecu or 8600 rev limit..
I ran a 15/19r out of the box on my stock ECU RXP with a stage 3 charger and it spun a perfect 8100 RPMs.. I'm assuming an RXT with the extra HP of the Rude1 could spin the same RPMs with the same prop?
And the same assumption goes for the 8600 limit. If it's 'perfect' for a stage III RXP then I'd assume the RXT with a stage III + Rude1 charger would land it on or around 8500 RPMs..?
For those who have tried it, if the 15/19r is not the best 3 blade match, please provide your input and experiences.

I understand..this is more for ocean riding
so far we have 1 15/18..who else out there has used a 3 blade with these mods on the stock ecu or 8600 rev limit?

I ran a 15/19 3 blade on my 05 RXT with a B-Kit and loved it I can tell you it will be hard for someone to out wholeshot you with that set up

I dont have a single test with 3 blade on the couch. I can give you some decent info on 4 blades with some pretty good hookup and acceleration IMO.
I agree with you on RXP 3 blade opinions. 15/19 with Rude1 stock ecu is pretty good without any tweaking.
I ran a skat 15/18.5 (small ring) with wicked acceleration but would run all over limiter with Rude1 stock ecu.
Good Luck with the ski!!!!
