RE: Dynaflite Butterfly build
 

Quigleywins,
Where are you having problems at, take offs, inflight turns, or landings? I didnt want to admitt, but I needed the instructor to ROG my butterfly. But after that, everything was fin. I did see that the stock throws were too much for a beginner. Fix her up, and let her sit for a while and train on a trainner. Dont let it turn you away from flying. If you are willing and able to, you might like the Parkzone Radian. It is a rtf, but it sure is fun and no exhaust mess to clean up! The last picture is a box that I made two of for my sons to carry thier DX6i and micro mcx in.

Opps, forgot I was on butterfly build. will post pictures in big wing build also.:D

Earl Just home from a vintage train ride we went from Castlemain to Molden and then walked into the town main street with a pipe band and police escort. In the main street we all had tea over 1000 people, what a great night out. Home a around 12 30 AM .
In flight turns are the problem ,all landings have been bad . All the throws are to much I am about to move the servos back so as to get more adjustment to center the control arms. I will also put the push rods in the holes that will give less movement . I am also thinking to do a new rudder as its far to large for a mug like me with a pair of 62 year old thumbs, now I not giving up If the worst happens I'l just build and let some one else fly. yours Paul T

Hi Guys ,
I needed a little weight up front on mine so I mounted my OS 28- 4 stroke on the Butterfly-Great combo!-Not over powered by any means-On a 4 oz tank I have stayed up flying for over 45 minutes ,just idling around and powering up to gain altitude every now and then-Very relaxing.I fly it to relax in between flying war birds etc. and also have used it many times as a trainer for my friends learning to fly-Great trainer for sure.I`ve had mine for over 10 years now and still love the shape of those huge wings.

RE: Dynaflite Butterfly build
 

Quigley If you have a computer radio just add a ton of Exponetial. Make sure you land directly into the wind. After I took the ailerons off mine I wish I would have kept them on. Not for banking but to keep it level in turns. If you don't have a simulator ..get one-BW

RE: Dynaflite Butterfly build
 

Quigley-watch this one again ...it might cheer you up.

Bonified Wingnut,
I watched the vedio, and that is what mine wanted to do. I was fast enough to kill throttle. This is why I had my instructor take her up. I will probably have to hand launch her for awhile.

RE: Dynaflite Butterfly build
 

You all need to hand launch this bird like the manual states. The big poly dihedral wing does not handle well on the ground w or w/out a tail wheel in any wind. hence your videos and experiences [:@]. I've got 7 flights on mine now and I have hand launched it every time. Wheel landed of course. The procedure is on Page 43 in the manual under takeoff.

Not that you probably CAN'T take off from the ground into the wind, but why when hand launching works great

Back to the KISS theory!

Have a good night.

RE: Dynaflite Butterfly build
 

That video was the only bad take off I had with it(except for the Heli-mix one). You just have to make sure you are straight into the wind. Get it rolling and let it go straight. Once you are on a takeoff roll don't try to change course.

RE: Dynaflite Butterfly build
 

I know one thing I'm not posting any photos of my flying efforts as I'd fill the thread . Just back from Bendigo LHS with a new engine mount and Fuel tank.I'l let you all know if I go with a redesigned tail. Yours Paul T

RE: Dynaflite Butterfly build
 

Well its all back togher again ready for the next plung into mother earth. Lifdump we have not seen you for a time now. Are you not allowed to play with us kids any more. Yours Paul T

RE: Dynaflite Butterfly build
 

Hi guys,
Thanks for thinking of me. I can play, but I've been sucked into the heli world. I'm flying gliders and heli's. Heli's at the moment. I am following along in your big wing build. Hi to everyone!!!

RE: Dynaflite Butterfly build
 

Well its been a long time, but the weather today was great and I just had to get to the field. I did not take the butterfly, took the Parkzone Radian. Brought the wrong tx so I had to rebind it to my dx7. There is where the problems started. Forgot to check the servo directions, and crashed. Broke the nose off. Hot glued and back in the air.

Because I like the Radian so much, I have been thinking about changing the Butterfly to brushless. Here is what I want to do, install an e-flite power 25, eflite pro 40 esc, and a 3200mah 3cell lipo. That setup will save a few ozs, but I am wonering if it will be too powerfull? I really didnt like the os .25fx, not a good engine to idle for long periods of time, and for me is too powerfull. Pluse if it were ele., I could fly it at a school field.:D

RE: Dynaflite Butterfly build
 

The Butterfly would be an excellent candidate for brushless. Some of the forums I read 3 years ago were about using geared rc car motors on Butterflies. With the cost of brushless down now I would definately go electric if I were to build another. The E-flight 25 might be more than enough but you could pack the fuel tank area full of the largest lipo you could get and you might not need lead in the nose. Then I think your flight times would be quite long. I usually don't worry about over powering with an electric, they don't care how long they idle and if it balances the plane it's perfect.-BW

RE: Dynaflite Butterfly build
 

The way I plan on going about it, I will take out the .25fx,throttle servo, and all fuel related items. Then I will weight the plane with just the two servos. I may be able go to the 15 power brushless. Or should I weight the plane with all equipment and compair that to the wieght recomendations that come with the motor? The weight of the 15 is 5.4 oz, and the 25 is 6.7

RE: Dynaflite Butterfly build
 

I would put the motor and esc you plan on using in the plane, then add something heavy (like lead) to the fuel tank area until the plane balances. Once it balances remove the lead and weigh it - then I would get a battery that weighed cloe to the same if not a little more. I would not worry about any wieght recommendations. SInce the Butterfly has such a light wingloading it won't matter. Even the 15 size brushless would power it fine. I figure anything between 300-500 watts. More is nice for the wind but I would not fly the Butterfly on a windy day. The lightest one will allow for a bigger battery. If you have none of the parts yet- remove the glow power and temporarily add weight to the firewall untill it balances, find out how much you need and find an ESC,Motor,Prop, battery combo that will match.-BW

RE: Dynaflite Butterfly build
 

Well I had my butterfly out at the club ground today. What fun, every body had a fly. I have the budy box with a Mode 1 with a mode 2 as trainer so all pressent could fly there correct mode. I think there was about 5 flights in all thats about 1 1/2 hours of flying. I still need to get that OS 20 running a little slower as the rise into the wind is fantastic. If you have ever flown one you will know exactly what I'm on about. Yours Paul T

RE: Dynaflite Butterfly build
 

Great to hear that Paul, you'll have to try and get some video sometime for us.-BW

RE: Dynaflite Butterfly build
 

Quigleywins,
Great to hear that you had some fun with the butterfly, and no crashes!:D Its always fun to fly the gliders! As soon as I sell some of my junk, I will be going electric butterfly!

RE: Dynaflite Butterfly build
 

Hi to all the butterfly operators and followers of this thread. I have been flying this week end with a total of around 7 flights about the best weekend I'v had with the butterfly. One point that was raised was that when the throttle was wide open the rise of the craft was to great . Norm the man with a long back ground in flying sugested that we add some down thrust to the engine (OS 20) With this completed by adding a wedge of 1/4 inch at the top of the mount the thing was near perfect . How many others have found this with there butterflys. Yours Paul T

RE: Dynaflite Butterfly build
 

I had a ton of down thrust in mine. It must have been cose to 10 degrees. I noticed a big problem with the last engine (Eolution 36) because I put less in it. I was thinking about adding down elevator mix with the throttle but the problem went away when I started using the smaller wing.-BW

RE: Dynaflite Butterfly build
 

I thought that I might have been Robinson Cruso 10 deg + is the amount I was thinking of Paul T

RE: Dynaflite Butterfly build
 

I put about an hour on the butterfly today its so much fun now that its trimed. yours Paul T

RE: Dynaflite Butterfly build
 

Hey Quigley,

Glad to hear your getting some time on her. I might fly mine this week along w a new Heli :D

I know, not a heli thread:eek:

Hows your weather been down there?

I still need to post my build notes on this thread one day!

Take care

RE: Dynaflite Butterfly build
 

Liftdump ,things are great I think that I'v been flying every week since Christmas. 5 of the fifty have seen air time now ,not all under my control but they have see air time. The butterfly is up there in time in the air with about 4 hours now, its had some repairs to the engine bay area but it flyes so well now I think I could go flying by my self. I am a slow learner which is hard to admit but theres no point in fooling ones self. Ian the instructor gets a good work out with 2 old bloks learning but he is so good. The big T that I'v been working on for the past 10 weeks will be flown this week end if the weather is ok. Its cool hear now and the rains have arrived which is great ,as we ,well Jenny has 4 horses which eat the stuff,if theres no grass then money that could be better spent on aircraft is used on hay 10 bales to the 1 ARF. LOL(I hope Jenny doesn't see this or there will be trouble).Keep in contact that Butterfly thread made me some good friends,of which you are one. One good thing about the butterfly is no one else has one ,every one in the club has had a fly. Yours for now the oldest learner in Australia Paul T

RE: Dynaflite Butterfly build
 

This is like talking to ones self,but if its to do with Butterflys then it goes hear. Last Sunday I flew the B'fly with out the buddy box. Because I run two DX7s one on mode 1 (which most in our club fly with) The other on mode 2 .which I like. When I Bineded the mode 2 Transmitter to the reciever all the trims were lost and one control was reversed. with every thing checked and fixed we took to the air. I was unable to trim it to fly (my inability) so it was landed trims altered and away we went again. No better landed again. Called on the only other mode 2 flyer there to fly and trim the thing . With all this completed 3 more flights with the motor stoping to end the flight ,I had a excellent day. The butterfly is what I needed to learn to fly its slow ,needs very little movement of the controls to alter height or direction.If in trouble throttle off and take your hands of the nobs. Its a pleasure to land and so slow.
I will measure the angles of the rudder so I can set them up the same way if required.I'm yet to put more down thrust on the motor (OS 20 FP) True love is a butterfly in the field on the wing. Yours Paul T
