So I'm now looking at either the 2212/26 or the Himax 2025-4200 and batteries to match.

I'm in the covering stage and will hopefully be ready to fly this weekend.

Ron,
I did try a 12x8 prop with the Razor350/6.6:1gb on the wattmeter. It pulled about 21.3-21.4A if I'm not mistaken. If you use a 3STP2100 or a 3STanic2200, they will handle the current, but I'm not sure how long your little Razor will last. I think Razors (except the 2500) are rated at 9A max, so pushign them to 14-15A the way most of us do is already asking for trouble... As for the AXI - I love my AXI28/08/24s and 28/20/12s, but I was disappointed with the performance of the little AXIs - the 22/12s and 22/08s. I had a 22/12/34 which was not nearly in the same league as my Razor 350, and my friend Joe (Goleith) tried a bunch of AXI 22/12s with various props in his old G-Ride and was not happy with them at all. Others find them useful though, so this is just my own opinion - take it or leave it.
Good luck on the maiden.

Doc and Mexico, I think you're confirming my suspicions.

I love my 2212/34 w/GWS 12x6 on my 12oz. foamy but I think anything over that weight will perform marginally at best. The thing I love about the AXI is the absolute quiet. And the fact that it's pretty easy on my etec 3s1200's.

I'm leaning towards the Himax 'cause it's what the bank account will allow.

Will let you know how it all goes.

I have the Axi 2212/26 and a 10x5E prop. It pulls nicely and is faster than I thought it would be. It hovers at a between 1/2 to 3/4 throttle and at full throttle accererlates pretty nicely. I may not keep this setup but for now it's working for me. I will say the Polyquest 1500 pulls better than the tanic 1100.

2 things ron - If you like the quietfactor of the AXI's you have to try an APC 12x6 E prop. I just did and it is even quieter than the SF's. I should be getting my wattmeter in the next couple days so I will confirm this but I hear that the E props draw lower amps than the SF so you may be able to bump it up to a 12x8 or 13x6 E prop. I had been flying my 2212/34 on an 11x3.8 SF APC. I always figured slower was better for 3D but I am finding that my theory was flawed. It climbs so much better and will finally KE with the added pitch.

RE: the Himax and the bank account - I feel your pain. I recently bought an E Flite 400. I am running it in a GWS GB D gearing and a Cobri shaft. So far power is pretty good on a 12x3.8 or a 12x6 E. I am waiting for a 13x6.5 to try it out. Troy from BPP swears it can put out 30 oz of thrust. And it only costs $55. HE says it is very much like a Himax 2025. HE thinks the magnets are actually better.

Just more to think about.

I got to put some time in on the Stella this evening, in about two hours I had the fuse complete, You have got to love Bills cutting details, even the sheeting fits perfectly. I really have to finish my E-star Porter but I just could not bring myself to covering tonight......Have I ever said I hate covering.....I really hate covering.

Cheers,
jim

Got mine finally finished last PM....

Final specs:

Lehner 1020/15 (working on gearing to keep amps around 18)
Hitec HS-55s
Berg 6 Rx
10x6 HD prop
Apogee 1570 3S pack

16 oz AUW with close to 40 oz of thrust easily...Should boogie! I could run my 5.5 to 1 with a 11x7 prop which draws 22 amps and gives close to 250 watts of juice, but I would need the Tanic 2200s and over 2 more ounces. Maybe I'll keep that for the windier days...

Will post pix later. Hope to maiden soon....

Anyone thought of putting split elevators in this plane? My thoughts were to use the area infront of the canopy for two servos and the pocket in the rear for the rudder. Don't know if it would gain anything other than just being different?

hey guys


i received a medusa power analyzer yesterday and was able to test my setup. i was stunned at how low my power was and it still fly's awesome. you guys on 175w should have some pretty spectacular performance.


i got 150w dropping to 148w after ~5 seconds
13.5A
and the pack voltage read 11v, once again

i might prop up to a 12x8 on a flight just to see what the extra power can do, and i also wanted to try an 11x10 for kicks.

i thought i would have been up in the 15's for amperage, i was way off. its good having low amps because i don't have to go easy on the throttle stick and i can do a powerful pattern flight.



also, i flew it this morning for 13 minutes and had a ball making up my own pattern routine. the stella slow rolls awesome and same with point rolls, its such a 'true' flyer.
when it came to landing it got a bit messy, because my flying field is a paddock that had 30+ head of cattle in there. my runway was covered with c##p, not the hard type but the nice fresh sloppy cow pat. so i came in for landing, yep you guessed it, stella made her tracks right through two of them, one on each wheel. both wheels where covered with c##p and the underside of the wing had been sprayed nicely with lumps of you know what. i think the cows meant to do it because there was a line of them half way down the runway going straight across which couldn't be dodged, damn cows are up to something.

Awaiting Maiden...

It's raining and windy out so I had to take a pic indoors.... The colors look a little wrinkled on the pix, but in person, it's a great finish. Still need a little detailing but so far, so good.

Hope to maiden tomorrow. Where are you guys running the CG, again?

Awesome, wondering how the stick will handle the power of the Lehner... Your prop brake is disabled right ? You know just for good measure it might be worth plugging the hollow stick with a piece of 3/16" dowel just for extra strength for that kind of power.

Bill,

I already stuffed a piece of carbon tubing down it with a bunch of Probond. Should be tough enough, right? Only one way to find out....My Jumping Jack was my "test plane" for this setup. Ripped the stick right off on that first flight. I learned my lesson with this motor.

twu01 - That is an AMAZING looking plane. I am blown away. Will you do solid white or something on the underside for orientation?

I have a Lehner just waiting for me to build a Stella. Please take some video.

I haven't decided on the underside yet....Maybe some lightning bolts or something "electrifying"...
