    RE: Great Planes Super Chipmunk EP arf

    Yes, I added 20 degrees flaps. I used CH6 on my Futaba T6J transmitter variable knob. 20 degrees flaps with knob fully clockwise. Of course I could set flaps for fixed throw on a switch.

    RE: Great Planes Super Chipmunk EP arf

    Yes, used flaperons, about 20 degrees flaps.  I used variable knob channel 6 on my Futaba T6J transmitter.  But it's a little to operate while flying so I will just chage to channel 5 switch I think.

    RE: Great Planes Super Chipmunk EP arf

    Took mine out today for her maiden. The weather hasn't been cooperative with temps in the teens or low twenties. Today was a bit warmer, mid 20's and 7mph winds. After a good range check I lined her up into the wind and throttled up. She tracked straight and lifted off rather abruptly and took a quick right. I let it climb to a safe altitude while holding in left aileron until I could give it some left aileron and down trim. Once trimmed for level flight at about 1/2 throttle she tracked nicely, holding it's course.
    It has a nice cruising speed at about 1/2 throttle and handles a bit mushy on low rates (set up as the manual) It makes big loops and long slowwwww rolls on low rates but when on high rates she does nice tight loops and quicker rolls.
    My first landing attempt she did a humpty bump and was too long so I took her around again. the second attempt was a little better but still long so the third time around I throttled back and about a foot off the ground I killed the throttle and she she slipped right in. On taxi back she nosed over when the wind pushed her tail up.
    After assisting another flier with his plane I put in a fresh battery and nothing would work.
    Once home I plugged in a fresh Lipo and my receiver didn't bind. I rebound the receiver and all was ok.
    Just as I got the rx bound my tx started beeping. low battery!!
    Good thing it happened then and not during a flight!
    Fair skies and light winds.

    RE: Great Planes Super Chipmunk EP arf

    Shirt-sleeve weather here Saturday, winds 12 with gusts to 15. Added a little right and down thrust to the motor. Had about8 flights with 1/2 throttle mostly and 7 minutes flght times.About 40% capacity left in 1300mah lipo after each flight. Like you said it flies very well at 1/2 throttle, even inverted with a good bit of down elevator. This thing is a bear to land in gusty wind. Made a few "tip and goes" scuffing up the wingtips a little. If I botch the approach I just give it full throttle and she pulls out quickly.I'm gradually increasing the dual rates and should be able to do nice aerobatics later. I'm using the recommended 8x6 slo-flier prop. Have you used a different one?

    RE: Great Planes Super Chipmunk EP arf

    I'm using the 8x6 slo flier prop as well with a rimfire 400 motor and 30A ESC with a 3S 1300 mAh 30C battery.
    I still don't know why the receiver lost it's bind. I'm using the Spectrum AR400 receiver.
    Gonna have to wait for a week or two to take her up again.
    My Tx battery is toast so ordered a new one.
    Fair skies and light winds.

    RE: Great Planes Super Chipmunk EP arf

    Thanks Tom. I have same plane setup except Electrifly 25A ESC.System draws 15 amps at full power. I followed Great Planes recommendations on this one as it is my first electric. Radio is Futaba T6J and R2006GS receiver. Set came bound out of the box and no troubles yet. Problem is transmitter uses alkaline cells. Futaba sellsNiMH battery and charger butfirst set of alkalines still have another weekend of flight in them.Starting to think about my next bird, need somethingbigger that won't break the bank. Probably fly next weekend while you freeze up there in New Joisy. Keep in touch.

    I finally gave in a ordered me a kit, I only need props and the airplane, the rest I have [8D], I also have a World Models 90 Chipmunk that I bought a week ago and completed and maidened last Friday.

    I'm having so much fun with that one that I thought I should expand my fleet of Chipmunks, next is the 30cc gas one

    RE: Great Planes Super Chipmunk EP arf

    On mine I will be using an E-flight 450/850kv brushless motor combine with a 25A Castel speed controller, 8/6 or 9/6 APC props, 1300ma Turnegy LiPo batts, HS 81s servos and a 4ch Spektrum receiver.

    Anyone want to comment on my choices please do so, I like to hear your opinion since I'm new to electrics.

    Tks.

    RE: Great Planes Super Chipmunk EP arf

    Hi CARS,

    Got pics of your big Chipmunk? I am not familiar with the E-flight motor or SH81s servos. If your motor is longer than the recommended Rimfire 400 28-30-950kV Electrify motor the cowl can be moved forward a little. Also there is about 1/4" clearance between motor diameter and inside of cowl. Firewall has 3 blindnuts located for the Rimfire 400 motor. The servo cutouts in tray and aileron mounts are snug fit for Futaba S3114 servo so you might need a little surgey to fit tthe SH81s. I suggest reinforcing the firewall with epoxy as motor vibration loosens the CA. Placebattery to get CG rather than put weight in the nose per manual. This thing is a joy to fly butlandings are a challenge in 15mph wind. Mine is set up for flaperons but has some right roll with flaps down for some reason I haven't figured out. Does nice aerobatics and I get 9-minute flights with 1200mah battery using mostly half throttle.

    I corrected to HS 81 they give you at 4.8v 36oz and at 6.v 41oz, more than enough. The motor is a park 450/890kv just a tad lower than the recomended, here is the link to the specs.

    Thanks you for the tips, I will for sure reinforce the firewall.

    The box finally got home, the brown truck dropped it off today in the afternoon when I was at the field flying my World Models 90 size chipmunk, here is my friend opening the box ( I thought I was going to have the privilege to do it, oh well )

    First impression, can you say Naiceeeee! all came intact with no damage from the brown truck [&:] ( amazing ) all parts came in plastic bags it is also a very low parts count, the cowl looks so delicate and I read here that I should handle it very gentle [X(]

    RE: Great Planes Super Chipmunk EP arf

    I was told by IB that I will have to reinforce the motor mount and maybe do a little of surgery to mount the HS81s and he is right on both counts, as you can see there is a need to add some epoxy on the motor mount also there is room on the servo mount plates on the wings to mount a little bigger servo like the HS81s.

    More later. [8D]

    Your going to love this plane. Itook mine out a few more times this year, * cold weather hampers flying up here*.. and every time Icome back home with a huge smile on my face and order more lipos for it..LOL. Yes, the cowl is v ery delicate. or it could just be me being a big ole bone head when I broke mine..

    It seems that everyone who see's this plane wants one. I think Great planes has a huge hit on their hands./

    Couldn't agreed more with you, big hit, I may get me a second one to keep for later, I also asked them to bring back the 120 size one.


    It is going to be windy here in NorCal for the next few days so my build is going to take about a week also I will be near Orlando Florida a few days next week with the family, I think the maiden will be next Sunday ( unless I snick out from work early

    I was asked to post pictures of the E-Flight 450/890kv motor mounting, this motor is longer than the Rimfire, I have been thinking all day today about how to go about it ( best scenario )

    First I thought I could keep the original firewall but it may end up in the way of the E-Flight motor, I think I'm going to install a second firewall about 1/2 inch behind the original one because my E-Flight motor is longer than the RimFire motor.

    RE: Great Planes Super Chipmunk EP arf

    For those that are using the recommended motor RimFire, can you give me the distance from the firewall to the prop washer, since I will be installing a new firewall I like to have that distance to have the proper clearance from the prop and the cowell.

    Thanks in advance.

    I'm done installing the new firewal on the E-Chippy, I will post pictures tonight after work by midnight.

    It came out good as I used the original one as a guide ( pictures will show in detail ) with this now the prop washer is flush with the cowl and not forward from it, the prop is just infront of the cowl ( looks really good this way ) I end up gluing the new firewal 1/2" bihind the original one ( as predicted ) using it to guide me for the correct position for the new firewall and using the 1/2" spacer was a great idea and made things very easy to instal

    RE: Great Planes Super Chipmunk EP arf

    The rest of the build should fallow the normal building sequence, the only thing her to look for is that the servo arm on the HS 81 end up right where the Futabas do be cause the push roads on the ailerons been fix ( can't be adjusted too much )

    One other thing I added a strip of white ductape on the inside of the cowl over the mounting holes, this is to reinforce the edges.
