Dynam SU-26m

[FLY BOY]

  :D Maiden flight of my new ride was today. CG was perfect as per instructions. After a little taxi running, She took right off. This is my first 3D aircraft. I'm a war bird guy.
Totally different world. After 2 minutes brought it back down, slid batt pack about half inch forward to add just a touch of nose weight, Perfect now for my flying style. Love how it responds to inputs so quickly. Snap rolls, loops, inverted flight, very responsive even on low rates. Did my first knife edge today, Easy money with this bird. Plenty of power, endless climb rate. Cant wait to learn how to hover. And OMG! it lands so easy a cave man could do it. Found myself just turning OFF the throttle on approach, and she glides and touches down like it was on auto pilot. AMAZING PLANE!!! Thank you MRC. I think this is my 4th or 5th plane from MRC and each one did not disappoint.  :cool:

Greetings Fly Boy,

Sweet!!

It sounds like you having major fun and THAT's what our hobby is all about.
Looking forward to hearing about your hovering successes.

Re: Dynam SU-26m

Just a note to be careful with 'glides to touchdown' on any 3D birds. Those wings tend to stop flying rather abruptly & she plops, often too hard. Get 'er up to a couple OS's & glide it as on your approach....just hold it until you see the phenomenon, get a feel for what triggers it, & land above that. Most 3D'rs land better with a touch of throttle.

Glad to hear you're so pleased with the new bird. Enjoy!

Re: Dynam SU-26m

Thanks for the input guys. I did do my home work before purchasing. Watched a few U-tube videos as well. I tried 1/4 throttle landing at first, ended up as a fly by. Not used the sensitivity of the controls. second approach I was lined up alot better, But I was still being twitchy with the controls. I was over center of run way, 8-10 feet up, Chopped the throttle and she floated down like an umbrella. Greased landings every time. Even the guys at the field were commenting how PRETTY the landings looked. All my war birds fly and land much differently. Once I get used to the control inputs, I'm sure it will be much better. Maiden flight was on low rates. During the second flight I flipped the switches to High. Started out at 40% pos expo. Ended up at 30% after 4 flights. By the 5th flight, my confidence was souring, and I was whole lot smoother with the sticks. Thats when the knife edge happend. I about pooped myself. HA <smiley image="smiley_good.gif"/>

Thanks for purchasing through motion its always a great thing to hear. I have several dynam planes and all of them have flown excellent for me . Thanks for sharing

RE: Dynam SU-26m

UPDATE  :D Have 10 fights now on the SU-26. Over joyed with the performance. Dont have the knife edge down yet, tried to hoover a couple times with no success. She would just do a hammer head. So I bought a CG machine, thinking I was nose heavy. Oh man was I ever. So who ever said just use your fingers was out in left field. I also added a Hobby Eagle AL-3 Gyro hoping to add some stability. Just waiting for good day to check all out. Rainy season is here.  :cool:

RE: Dynam SU-26m

KNIFE EDGE? NO PROBLEM. HOOVER? NO PROBLEM. Thanks to the HOBBY EAGLE AL-3 Gyro, took the twitch out of my thumbs, and with the added stability, made doings theses things a snap to learn. I really love the AUTO PILOT style landings that happen with the AL-3 as well. Great product all around. Thanks MRC. My new P51 Strega is on the way, and yes I ordered a gyro for that one to.  :D

RE: Dynam SU-26m

Sun broke out in the Pacific NW area today to my surprise. Raced to the air field with my SU 26m.
Got to fly extensively. WOW WOW WOW. Practiced a split S, to inverted, to a knife edge as a routine, Then the knife edge turned into a banked turn knife edge that looked so cool. So added the banked turn knife edge to the routine. Flipped her level and snapped her into a hoover. Its so easy with plane!!!!, The stabilizer helped learn the basic mechanics of theses moves with confidence, but now its happening with it turned off more and more. I still like to flip the gyro on during landings though. Air planes and parts cost money, and with the Hobby Eagle flight stabilizer/gyro, handling cross winds or just like today with no wind at all, greased landing every time, with confidence. I highly recommend this plane to any body wanting to learn 3D. Its been an excellent trainer for this and the more experienced pilot will have fun to. This is my first 3D plane and I'm having a blast. :D

Merry Christmas Flyboy!

Glad to hear your SU26 is doing so well. That is one I have thought getting about many times. I have bought a couple of the Eagle gyros, but have not installed any yet. One thing I am not completely clear on is how to set the switch to turn it on and off. There were no instructions in the boxes, so guess I will have to investigate the on-line manual when I finally use one of them.

Enjoy the flying, and best wishes for the New Year.

No worries Loneflier, The instructions come in the form of a pdf file on line at MRC. The instructions are good with videos to. The only thing u need is a channel just for the gyro, and a 3 position switch to get all 3 modes at your finger tips. Or you can do what I did. My DX6I dont have a 3 position switch. So I just used 2 functions. Off, and normal mode connected through the flap switch and flap channel. My SU26M dont have flaps so I used that channel for the gyro. Its very IMPORTANT to be able to turn the gyro off in case of a malfunction, or hooked up wrong on maiden flight of the gyro. Later I discovered I can get that 3rd position thru flap mixing.  I'm screwed when it comes to installing the gyro on my 6 channel aircraft. No channel for the gyro. This is when I need a DX7 or better.  For more helpful info, see gyro section of the MRC forum. Happy Landings and Happy New Year from the Pacific NW.

RE: Dynam SU-26m

Thanks Flyboy,

The switch should not be an issue, I have the DX9 radio. I will have to go back to the MRC website and download the instructions from their files and print them. Right now, I am pretty happy with the way all of my planes are flying, but I do have a couple put back that might need a gyro, so I am holding off right now. I have used the HK receivers with the gyro built in for some of my 800mm FMS warbirds, and that works out really well, but not sure I can turn off the gyro on those. Fortunately, all has worked well, and I double and triple checked the throws to make sure all was working correctly before flying them.

Thanks again for the help. Happy flying out there in the Pacific NW!

BTW-I went back and checked, and the HK Orange gyro receivers do have a way to turn them on or off through the AUX channel assignment.

RE: Dynam SU-26m

The Long Haul: Have around 80 flights give or take a few, on my Dynam SU26 3D plane. Still one of my favorite planes in my hanger. Holding up nicely. Motor, ESC and all servos working well. This plane has been a blast to learn 3D with. 
Added a flat spin to my routine as of late. Only up grades thus far have been of course Dave Brown shock absorbing tires and a APC 14x8 prop. Hobby Eagle gyro has been a blast to. Did have a little problem lately with cowling wanting to creep forward towards the prop during flight, A little piece of scotch tape on the belly side of the cowling has been working for me. Over all this bird has been tough. Even on hard landings the air frame absorbs the impact with out cracking the foam on the fuse. Landing gear dont seem to be quite as stiff when new, but hanging in there. If your looking for a great 3D trainer, this plane is the ticket. Low cost and low maint. Happy flying from the Pacific NW :cool:

RE: Dynam SU-26m

Long Haul: Well at around 100 flights had to replace the elevator servo today. The plastic gears stripped out completely. Also had to tighten all the motor mount screws, They started coming loose as a heavy vibration was accureing at full throttle tipping me off to a problem. Cowling sliding forward problem during flight revealed its self as a magnet coming unglued in the cowling itself. CA glued cured this problem. Last but not least, had to replace the landing gear. It lost all of its integrety, as the plane was bottoming out onto the fuse on the easiest of landings. Thinking of a cross bar mod to keep the gear from spreading out to far on hard landings. Even though this mod may increase longevity of the gear, it will signifinitly make the gear stiffer, and may comprimise the mounting point where the gear attatches to the craft. Will keep u updated  :cool:

RE: Dynam SU-26m

LONG HAUL: Flight 103, bad day at the airfield today,   :(   Rudder servo stripped out during flight. Normaly not a huge deal, but for some reason I lost power to the motor at the moment of malfunction. Turned her into the wind and down she came. Dead stick landing. Retrieved the aircraft and took her the bench. Bent the gear a little, found the broken rudder servo, Refired the motor and all was good there, dont figure. I heard the servo go during the flight as it sounded like the prop was chopping water. At first I thought it was a motor problem because of the noise it was making as it went down. But when I got to the bench and heard the servo gear clacking and freaking out, I said ok, that explains the noise, but why did I lose power?  :huh:  I should of been able to fly her back to the run way, just with no rudder control. I'm stumped. Over all it appears just needing another new servo. I'm open for ideas. The batt tested at 3.75 per cell after the crash.

Maybe the servo jammed momentarily on a broken gear tooth and it drew too many amps? Just guessin' here.... :)

That was my first thought, Thank you, Guess I'm not crazy after all.  ;)
