We is my dad, and only my dad lol im not building it cuz i cant build for crap lol


but today someone at the field had an OMP 47" edge that they scratch built from plans, and they let me fly it. WOW!!!! I have never flown a profile that was more stable in a harrier, upright or inverted. He doesnt fly much 3D, so he was amazed to see his plane do that stuff. But that plane was awesome!! I hope i can get mine to fly like that!

I was dragging his tail in the grass in harriers, touching from hovering, basically scaring him every way possible


Hopefully more work can be done this weekend

all that's left is the mounting the Saito 72, the fuel tank, and the throttle servo

I have all the throws set, i set 3 inches up and 3 inches down for ailerons, rudder goes 1/4" from the elevators, and about 4 inches on the elevator.

I also set in some spoilerons, just to see how stable i really can get the harrier to be.

Anyone know the best 3D CG for it?

Thanks!
Scott

CG<<?

W.T.F is CG?¿?

It's DONE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Just going to check the lateral balance, make the CG around 1 and 3/4 inches back, and fire it up.

Maybe get to maiden it later today, have to fix the yak (wont start) and a 40 size extra, stab broke from flutter.


Later All!

IT FLEW!!!!!!!!!!!

well, sorta....

At the silver elbow thing that goes from the carburator to the engine on the saito, there was a missing o-ring so it was sucking air and ran weird, but we didnt find that out till after i flew it.

So we spent 2 tanks just tuning it, for no result, cuz we found that it was missing that o-ring. But i did fly it for about 10 minutes, and it flew AWESOME!!!

The harriers are SOOO stable compared to the katana, and i didnt even need the spoilerons i programmed in. It hovered a little bit over half throttle, rolled really fast, and does great waterfalls.

Rolling harriers are really axial, roll pretty fast too!

Flat spins are insane!! I only tried an inverted, but it just sat there and spun around, didnt even fall down till i let off the throttle, and climbed when i gave it throttle.

It's a VERY stable hoverer, i can tell im going to be doing alot of low torking with it.

Video to come soon, as soon as I buy some new Mini DV tapes for the camera.


Later!

Congrats Scott. Didn't seem like it took you too long. One thing I noticed on a friends plane this past week was the fact he did not fule proof the plane very well and the oil damage was extensive. This is something many overlook so be sure to fuel proof with thinned epoxy over exposed areas such as the tail servo mounts or any foam that may show. Quick and easy and sure does add longevity to the airframe. Now get that engine fixed and show us some video.

i think that's why my throttle servo came off, the epoxy didnt hold to the fuse.

SO, we cut 2 square holes where the servo mounts, and put longer square wood on the servo so it went into the fuse. Much more stable now.

I love it so much i went out in the back yard and taxied up and down the yard like it was an R/C car, and to see if our o-ring worked. I dont know if it did cuz im new to 4 strokes.

im looking at all the tapes i have to see if there is somthing i can tape over.

I might get some video this weekend, we're going to an IMAC and im going to take this along to fool around with on friday.

Later!
