Loved it! Looks like she flew great. Good job buddy!

I actually only need to make the intakes to find out where the wing attaches because the wing butts up against the back of the intake pieces.

As you can tell its begging for a 4s. I have an 8x8 and an 8x10 I might want to try on it. I tried the 8x8 on V2, I haven't busted out the 8x10 yet. Thoughts?Success
Go for it! 8x10 on 6s😉

Right there is why I love having a thrust stand and watt meter. I don't care what the manufacturer's specs are or who claims the have the best prop. Little bit of bench testing and you soon know what or whatnot that motor can do and with what prop and esc.
Try the smaller prop first just doing some vertical thrust test, run it a bit at half then check temperature of the motor and esc and if all good give it a few wot bursts and check again. Now especially the motor you will get some heat no matter what but just make sure you can hold onto it. Up in the air it should run a little cooler. If everything stays cool you can try the next prop.
If you do have a watt / amp meter hook it up while you are testing.

Baby steps my friend lol. What I do want to do is get more rpm and more voltage would definitely do that. I have been looking at hi rev motors as well to get more revolutions per volt. Larger motors that do have 2200-2700Kv. seen some at the LHS website and it has the gears turning sorta speak

My volt meter will do amps and watts is just a mere calculation. But I think we have established my volt meter is not that accurate. It will be stepping things up in a process that will help me see the potential. Thanks for the tipsRight there is why I love having a thrust stand and watt meter.

Upping the volts will perk up any motor within reason, some just can't handle it though.
Put this on your wish list
GepRC 2750kv one

6X3 TGS prop from HK
40A esc
A good 4S battery and you will rock

I think my watt/amp meter gauge was only 15.00 or so, maybe even less from HK but BangGood, Aliexpress all have them . Amp and watts you want to see a live reading while you are powering up the motor.

I also seen some motors that are long and narrow with high Kv ratings, I think they were from E-flite. Is that an advantage somehow?Upping the volts will perk up any motor within reason, some just can't handle it though.

Those would be for edf’s I believe.
Sweet! No orientation issues for sure!

Could be, they didn't say EDF specific like others did though.
I do have EDF's on the wish list

Not necessarily , on a lot of these smaller builds a good strong quad racing motor will do just great. You put the larger motor in and it may have the same kv but it also weighs more so that robs some power right there, then you will probably require a much larger battery, more weight.
. Now as you get into the little larger and heavier planes somewhere in there the larger motor can have more grunt and keep the rpm up where the quad motor starts to die off. My F117 is fairly light and has that GepRC motor in it on1800 4S battery, 40A esc and a 6X3 TGS prop, I think it goes great and really it isn't a very aerodynamic jet , put it into a sleek light little build and you would have a rocket.

You do have some awesome little pushers man, another great build. I did see what you have going on in the garage on your other thread, looks like an interesting jet build. You like your fighter jets, and so do INot necessarily , on a lot of these smaller builds a good strong quad racing motor will do just great.

I did a ton of fighter jets, loads of prop slots then we migrated to more scale looking jets and the only way was to go to pushers and after a while I got tired of the jets and started doing old warbirds. They all have their place and it is fun to fly all the different types of planes. If anything the wider scope of planes you have it does help your skill level. That big jet is a heavy weight with a ton of horse power, if things aren't perfect there is no mercy and as you see I am starting over on a complete new build.
