Default RC Lander 70mm EDF Test

Hello All,
Thought I'd share my tests on this RC Lander. This is also a vid so those interested can hear the 10 blade version.

I used a 6S Revo 3200mah 40C HV lipo charged to 4.30v/cell.
It should fare pretty well in the 2.3lb F-16.

Just got the programmer card for the ESC today. Going to make some adjustments including changing the timing to "high" as suggested by the RC Lander people. If the results are any better, I will post them.

I currently have the timing set at automatic. Does that mean that the ESC will automatically opt for the higher timing? If so, I'll leave well enough alone.

The sound from that edf is fantastic!!!! Even cooler is your thrust calculator rig. clearly would work for many type motor applications. Would you say it has a accuracy of a few grams either way?

Thanks for sharng that vid. Looking forward to a flight vid if you can.

Thanks Tobydogs. I agree, this unit does sound very jet like. I wanted to get the 10 blade in opposed to the 12 and 14 available thinking there would be a little less load and still get the whoosh sound. RC Lander has since come out with an 8 blade that is supposed to sound good also but has even better specs.

This thrust rig gives me a reasonable idea of what thrust this unit is producing. The axis of the EDF is about 3mm lower than the axis of the scale so if anything, it probably comes up a little short of what the EDF is actually producing. I used metal ball bearing slides to mount it on but I don't think they are totally resistance free. At worst, I would guess that this rig is probably within several grams considering the scale itself has an added +/- .005kg accuracy.

I am going to fly the F-16 with it's stock internals first so that I have a basis of comparison. When I get the chance, I'll record both stock and upgrade flights.
