Warp Drive Props

[BOATCH]

I have a Warpdrive prop on my 503 d/i with a B box but it looks like if the 503 runs out of revs cause the rev counter revs up to 6500Rpm. If i cruise at 5800 rpm it feels like if i loose lift and the motor sounds like if it is running on less revs than it shows on the rev counter.

I use a 503/warp drive on my trike and my tach is a westach or something like that,

If you use the same one its quite common for them to be not to accurate mine over reads by 10%,

I bought off ebay a hand help laser tach to check my RPM and set my prop to get the correct RPM,

6500rpm max is the right fig for a 503 by the way.

I see this is a 2.58 VO gearbox,what does the VO stand for.

I think my gearbox ratio is 2.54 and mines a B box, I have not heard of a VO.

Hi,maybe your tacho isn't accurate,but I run a warpdrive on 503/e-box --- static max 6300 rpm,cruise 4800-5000 rpm,maybe you could do with another degree or two more blade pitch

I fly a 503 b box windlass with 2 blade warp and Max rpm iuis 6540 static and on take off 6600
My cruise straight and level dual is about 5800 rpm and solo 5000 rpm and runs fine with nice climb rate and about 10 -13 liters an hour feul burn.
