    RE: E-Flite Mini Pulse XT Owner's Club

    I just slapped in a battery and a shorting plug...   The battery is a 2100mAh 11.2v  last flight, I came in with throttle barely engaged, flaired and it dropped into the snow, no roll.  The flight was about 5 minutes in duration, just enough to do some loops a few rolls, and several low passes.  I was not terribly impressed with the rolls, they seemed sloppy, but this could have been the loose nut behind the steering wheel.

    Next flight I do will be to see if the ailerons roll the plane a little more cleanly..   from there I will play with different batteries more to adjust the CG (bigger heavier CG will move forward/smaller lighter shift back)   than to evaluate power.

    RE: E-Flite Mini Pulse XT Owner's Club

    I've been thinking about the "Float" condition you describe, and I did experience it.   An easy fix would be backwards flaps....  It is so light that having the ailerons droop on approach would probably be counter productive...  If , however the ailerons flexed upwards, it would probably require a bit more up elevator and cause it to drop out of the air a little quicker...  just a thought..  proceed with caution at your own risk.

    RE: E-Flite Mini Pulse XT Owner's Club

    Has anyone tried using the Mix function on ailerons in order to tinker with adding reflex so that the plane doesn't float on landing approach?

    RE: E-Flite Mini Pulse XT Owner's Club

    I've tried both flaperons and spoilerons. I rather prefer the spoilerons to, as you say, add 'reflex.' It still floats, but not as badly. I've just begun testing adding some down elevator to the mix for a decent approach with so far mixed results. Glad to see someone else is tinkering around with this stuff. Let me know what you think?

    RE: E-Flite Mini Pulse XT Owner's Club

    Wondering about about putting a Heads UP RC 450 Speed in a Mini Pulse XT. Only real difference I can see between that and a Park 450 (other than $27) is that the HURC is 1200 Kv and the Park is 890 Kv. I realize most everyone is saying go with a 480 rather than the 450 but for right now the 450 is a better choice for me. Any thoughts on this, from anyone, please?

    RE: E-Flite Mini Pulse XT Owner's Club

    You might see a little performance improvement.... It would depend on things like weight, prop selection, phase of the moon...
    I'm kidding with that last one. But, from my experience you're tinkering around the edges. I doubt it will make "Knife edge" flight any easier to maintain. I'm still fiddleing with surface throws in order to do a good Lomcevek...

    RE: E-Flite Mini Pulse XT Owner's Club

    I did manage to get a 20 minute flight in on this last Saturday with a wind that was about 12 kts. 

    With this wind the landing was very smooth almost bird like floating in to my feet.  One thing I did notice was the plane with its out of the box motor has more than enough power, almost too much.   I had to fly maneuvors at half throttle or the plane was just going too fast.  First quarter of a loop I would bump a little additional throttle, but latter half, throttle was cut back.  I found aileron to be way too sensitive around center, so I'll be programming in exponential.  I never got to the more advanced moves since I used the back half of my flight envelop for practice approach/TnG's and landings.

    RE: E-Flite Mini Pulse XT Owner's Club

    Last weekend's flights taught me the necessity of having exponential as an option, expecially for T/O.  The plane came off the ground rather quickly, surprising me and I over controlled to correct a dropping left wing tip only to have the right pointed at the ground.  All flights to date would seem to indicate that the factory set up gives plenty of throw , maybe too much throw.  So last nite I programmed the DX7 Ele/Ail switches to provide Exponential.  I probably did it incorrectly, as I have normal linear throw when the switch is in the "1" and expo when you move the switch up to the "0" position.  It doesn't really matter as initially,  I only intend to use expo for take off.  May change my mind with some additional stick time.  I have it set at 75% and would like to know what others are using?


    Thanks

    Wondering about about putting a Heads UP RC 450 Speed in a Mini Pulse XT. Only real difference I can see between that and a Park 450 (other than $27) is that the HURC is 1200 Kv and the Park is 890 Kv. I realize most everyone is saying go with a 480 rather than the 450 but for right now the 450 is a better choice for me. Any thoughts on this, from anyone, please?
    Well, I just did exactly that. My PNP 450 gave up the ghost, must have a shorted wire. Thought I'd splurge on a Hyperion, but couldn't find the right one in stock, so after 90 min of frustration, I went with the easy and reliable option: Jeff's Park 450 Sport at HeadsUp RC.

    I believe this is a Suppo motor, and I was very impressed with it's brother, the Park 480. This Park 450 drops right into the MPXT, but the shaft and prop adapter are slightly longer than the PNP's, so I'll have to cut the standoffs to close the spinner gap.

    After 2 flights today, I'm very impressed with this motor. It's vastly superior to the flimsy E Flite PNP 450 (which sells for something ridiculous like $80even more than the "real" 450. [X(]). With the TP 9 X 6E prop from HeadsUp, it now will knife edge all the way around the field with ease. (The E Flite PNP limped along making ugly vibration and prop noise for about 50 ft before it lost too much altitude to continue). I'm not sure if vertical is unlimited, but it's very impressive. All this with equal or better flight times. My quick initial Amp draw check indicated almost exactly what Jeff claims with this prop: 17 Amps. (Jeff's test says 18 Amps, maybe his battery was better. Mine was a fresh Thunder Power Pro Lite 2100 so it should be good). I would not use 10 inch props with this motor. They barely work with the E Flite 890 KV, and this Suppo Park 450 is 1100 KVit would surely burn up. It works GREAT with the TP 9 X 6 (an APC clone) on the MPXT.

    I'm totally pleased with this purchase. One more satisfied customer for Heads Up RC. It sure beats the price of the E flite stuff, despite being equal or better quality. I'd love to try a Hyperion some day, but I must say, they sure don't make it easy to choose the right motor! The Heads Up site cannot be beat.

    I see no reason the fuss with the Park 480. The one at Heads Up is nice, but even heavier than the E Flite 480, and would require fabricating a new mounting plate. I just don't see the need. The Heads Up Park 450 ROCKS!

    RE: E-Flite Mini Pulse XT Owner's Club

    i just got aMini Pulse PNP
    did about five flights over the weekend
    it flys like a dream
    beefed up the lg mount with a 1/8 thick sheet of plywood
    changed out all the servols with hitec hs-65
    added some epoxy to motor mount and fuselage

    RE: E-Flite Mini Pulse XT Owner's Club

    I have never been a huge fan of the blue and orange coloring scheme on the MPXT, and I wanted to make my plane unique, so I recovered and trimmed her to look more like a racer.[img]



    Sadly this happened on the first flight. I was flying with a friend and when we were making a low pass down the runway his prop hit my tail and sliced it completely off, resulting in a full throttle nose dive from about thirty feet. [img]

    Some call it crashing... I call it agressive flight testing.

    That recovering scheme is so beautiful and aweso..... AWWWWWWW!
    I'm so sorry.
    I feel for you. Really though, kudos for doing something creative with the covering. I love(d) it.
