    40mph stock set up using 4s 4300 mah zippy lipos. Radared using a cheapy Bushnell unit with the front shroud removed for improved accuracy.

    Some batteries (the cheap ones) do not hold the voltage under load... you'd be suprprised of how much they drop... I have not seen his setup or anything but just by him saying that he got a "no namer" cheap off of ebay tells me that the batteries have a good
    chance of being the problem... at least one of the major problems.

    Instead of editing my post I just wanted to add that I used a Watts Up meter and measured spikes at its max plus. Last max reading was 100.72 Amps. Is or has anyone been able to log their amp draw using 8xl and k45mm prop?

    Ghostofpf1. I sent an MO today to Optics Planet for the same radargun to measure the true speeds on both my moded SV 27 and moded BJ 26. From what I know the Bushnells are quite accurate. I ve seen guys use them in drag racing tracks.

    I found that removing the smoked front cover enhanced it's ability to pick things up.

    nope, more likely over-propped and not letting the motor hit peak revs IME. try a 437/3 or x440 2-blade, I think you'll get more speed.
    ...you're using lipos, right?

    Ctonez is right Kssi. Like he said try the Octura x 437 two or three bladed or a 440 2 blades. Never try a 442 with an AMMO as you may fry the batteries... A grim 42 x 55 is way over propping for a 2 pole AMMO 2300.
