Speedfire HV

Fun steps first... I bought a neu 1512 2.5d on clearance and just slapped on a spare 6.7 p32 box I had around. It took some grinding, but it seems to be in good shape.

I also needed a new esc, so I picked up a 160hv. The hv lite was way too $$$, so I thawed the regular one into a lite.

Pics of plane to follow!

Wow Rich! That's a lot of ingenuity. I had a chance to run one of the newer designed Neu rotors and pinions recently. It was kind of a crazy hot liner set up; small light weight motor spinning very high rpm. 1508.5 1.5D; 4800 kv / 6.7 gear ratio, 15x18 inch prop, on 6S 2700. Now that's asking for trouble and more of a 4s kind of set up normally, but it survived and peaked at 5500 watts using throttle delay and max brake. From this test, I see that the new pinion is very well worth it. I mention this in case you have the older style pinion, in which case you might want to use a soft brake. Can't wait to your see the HV rocket! E

Hey Rich, are you going to support those thin motor wires with something? Just asking cause compared to the 8 AWG wires on the ICE they are a bit on the thin side.

Remember this?

Should be a fun setup! What plane?

Eric, I have no idea if this is newest pinion or rotor, all I know is that the pinion was just purchased new, and the box came from an 1107 I had laying around. BTW, its not ingenuity, its frugality!

Josef, I will mount the esc on a Popsicle stick, I just need to develop an appetite for grape Popsicle which is all I have in the freezer at the moment.

Going on the latest and greatest f5b to emerge from cz... the speedfire

I wish Steve would still sell the 6.7:1 with pinion for his motors that don't have a gb on his clearance page. I was going to buy a clearance motor but he wouldn't sell me a gb for it... bummer. Looking forward to see where this goes.

That is one beautiful plane.

Yes, it goes together fast... the horns are in very low though, I may bore them out and raise them if the servos demonstrate any play... too early to tell. I just finished shaving the clevises and filing away one wiper...
