RE: AXI 5330/F3A Flight Report
Well, now having 8 flights on the Eclipse I can say that the Axi is better than I thought it would be. I got flights 3 -8 today in 20 mph+ winds. Plenty of power with the 22x12 in the wind. I flew the masters pattern a few times and pulled between 2500 and 3300 out of it. It dropped when i set my throttle curve differently. This was in extreme wind also and I'm not used to the airspeed with such a big prop. I'm sure I can keep it down under 2500mah for regular flight. Time will tell.
If you're considering going the electric route, this could be the motor for ya. Very, impressive upline power. And I'm not just saying it as it's what I'm flying. If it wasn't impressive, I would post that also. I'll have to get some video when the wind calms down.

Chris with the #'s your talking, you could use the 4200 5s2pp there 63 and 100 amp rated, according to what amps your running. There a little cheaper and 3.1 OZ lighter 3300 is only 78% of capacity.

Steve,
After I have several in contest flights on the eclipse I will probably either switch to the Tp 4200's or even the Flight power 3700's if it's possible. I could use the weight savings. The flight power looks like they have some impressive numbers. But, as I was flying yesterday in the wind, I was getting tossed around pretty good. I don't know if I want to go any lighter. Actually, the thought has crossed my mind to strap in 20 ounces of fuel to the cg on windy day's. Then it will have a comparable takeoff weight to glow... lol

RE: AXI 5330/F3A Flight Report
I'm talking about taking it to 12 or 12 1/2 though. Takeoff weight isn't what is judged right? I mean if a glow plane can be 11 lbs dry, 12 1/2 or so wet (depending on size of tank) then I ought to be able to add a fuel tank on cg to get my takeoff weight up to the same, seeing as the ama won't give any weight credit for electrics. This would be an interesting point to test with them.

If the rule people get picky I suppose you could use fuel
There are many days when my plane (10.3 lbs) is waaaaaaay too light.

RE: AXI 5330/F3A Flight Report
Exactly Chad. I think it may be something worth trying.
And 10.3 pounds?? Holy crap man. Don't fly that thing. It's gonna break apart. lol
I honestly don't think I want a plane that light. Especially electric. I think it was an advantage with glow when we didn't have the props to pull the uplines and slow down the downlines like the 22 inchers that we're running now. But my plane fly's so slow now that I can't see the advantage to being so light. Is there one in your opinion?
Of course, it makes for great bragging rights, and I think it would be between you and craig blodgett for those.

Phillipe Marquet from Belgium was like 8.8 lbs RTF with his electric Lazulite. He used super small packs and a small Hacker (I think the L not XL).....but his plane appeared (IMO anyways) to not have the energy from the weight to really draw well through the manuvers....tough to explain but I think you will know what I mean. Almost like a foamy flying pattern!

RE: AXI 5330/F3A Flight Report
Hey guys, I'm building a Sr Telemaster (8' version) for aerial video work. The AUW of the plane will be in the 15-18lb neighborhood. My 5330 F3A is sitting on my workbench awaiting installation, but I am unsure which prop to use. I'll be powering it with a 10s pack, and my intention isn't to have a "fast" plane. I want the ability to drag it across the sky nice and slowly, but have power to use if necessary, and to allow short takeoffs. Love to hear your opinions on this.
Thanks,
Greg
Thanks,
Greg

Hello Chris,
More weight does not make your plane fly better in the wind: being able to carry your speed better at the top of a maneuver does!
If the plane sits poorly in the wind or turbulence, then maybe it's the design, or maybe it's tail-heavy.
best regards,
Dean Pappas

RE: AXI 5330/F3A Flight Report
From personal experience with heavy airplanes, *cough*, they do penetrate better. Everything is a trade off of something else... but I have had a 12.5 pattern plane with an AXI and you would have enough power to pull through the top of any manuever even if you added another pound to the airframe. Even at that you wouldn't hit full throttle.
No argument that in general lighter is better... but given the choice I would rather have an 11 lb pattern plane than a 10 (talking electric here).

Hello Greg,
Based on the numbers, and a quick check in motocalc, a 20-8 prop on 10 lithium cells should yield about 60A of current draw, about 18 lbs of thrust, and a flight speed around 50 mph. Adding diameter adds current, quickly! (3rd power relationship)
Hope this helps for a starting point.

RE: AXI 5330/F3A Flight Report
I had some questions about how to hard mount the AXI to the nose ring, so I thought I would post it here.
The mount I used, and there are few different ways to do this obviously, was to use two carbon disc shaped plates, Aeropoxied to each other, then to the nose ring of the plane. On the AXI there are two sets of holes to mount the motor when mounting to the front (wires aft).
The first plate has the outside holes drilled out, and the motor mounted to that plate. There are cut outs in the front of the motor to allow air to flow through and over the windings and magnets. These holes are also relieved in this plate. The second plate is more of a ring. It allows the first plate to be attached to it while also allowing a recess for for the screws that attach the motor to the first plate and allow the screws to remain flush to the front of the nose ring.
If you look carefully at the picture below, you will see that there are two plates there, and that there is relief for the screws that attach the motor to the assembly. Also, you will notice that the reason for using the outside holes is to allow room for the prop adapter that slides over the shaft.
I have hard mounted this motor in several planes with this method and have yet to have an issue. I have talked to others who have used similar set ups, but have also used support from stringers extending aft from the ring and secured to the fuse. There are probably a few other ways to do this, but my Genesis has close to 150 flights with no problems with a method like this.

RE: AXI 5330/F3A Flight Report
Looks like you have stringer on the sides with an unusual shape. Is there a purpose for this? Do you also have a stringer on the top or just the sides?
Thanks looks good.

RE: AXI 5330/F3A Flight Report
Steve,
Actually I should have posted this last night, but that stringer is what was left over from an engine mount. The second picture is from an airplane that was a glow powered version and had a large carbon mount in the nose that was put in by they guy I bought it from. I tried to remove as much as possible, but that last little stringer was too tough to get out.

RE: AXI 5330/F3A Flight Report
A small stringer at the sides and top is probably a good idea anyhow, and probably needed if fuse is a light layup.

RE: AXI 5330/F3A Flight Report
Ok I bought the AXI from Tom [link=http://www.blackbirdrc.com/]http://www.blackbirdrc.com/[/link] going to give this a try. Already have the same props from the Hacker C50-14xl and TP 5300's would love to afford the 3700 flight powers to try, but that's later.
I might add that he shipped 1/2 hour after I bought it online but he was there and not on the road, Thanks Tom.

Hey Steve.
I don't know if anyone has mentioned to you, and I forgot in our emails, but you will need a 12mm prop reamer like the fox reamer to ream out the prop.
Also, the mounting similar to Tom's that I was telling you about in my Eclipse is at the top of this page.
And, sell those Tp's man, you can get 3 set's of 3700's for that price. 
Glad you chose Axi after your bad experience!!
Chris

RE: AXI 5330/F3A Flight Report
Finally flew the AXI/F3A today man mucho power seems to be a big increase over the Hacker C50-14xl same prop, batteries, and controller. Now if I can just tame it with a throttle curve I like, still think my controller if a defective, but will keep playing with it.
Ok for #'s mine is a little higher than I have seen in flight was peak 76.59 amps (wattsup meter)but that's with a bad throttle setup, flew P-07 as normal after a test flight of 4 minutes, the P-07 same as usual but only put back in 3255 MAH instead of the 3700-3800 with the Hacker, didn't need a brake does fine with the 22X12 for downlines, verticals was very fast compared to the Hacker, with my poor setup one click was way over the top, never even came close to full throttle.
These guys have something good here, all I can say is $229 from Tom will make you a beleiver too. Next will be the 5320/28 and new controller.
Thanks Tom and Chris for sharing this info on this HOOS with everyone.
