Today I was able to finish the engine controls and cowl fitting. I took to much time fiddling with the choke servo linkage. In my case the muffler is right on the way of the link and I needed to find the correct angle and throws for the choke to fully open and close. I think it was worthy, now all my engine controls are going to be on the transmitter, including the engine kill. On my next opportunity I believe I will be able to finish the tail feathers and start setting up the electronics. I am sure that if I didn't had such a busy medical care schedule I would have finish by now. This kit is a really fast build and a joy to work on.
I have to go, dinner engagement with some friends so it will be until tomorrow. |
RE: RedWing MX2 Build
It is looking great! I'm so happy to see all you guys putting these together and loving them. I put a lot of time and effort into this airframe, along with the factory of course! I can't wait to see more videos coming along

RE: RedWing MX2 Build
Hi:
I have a turnigy 26cc [though it says on the box its a 32cc ] from hobbyking that has a displacement of 3.0hp. Will this be enough to comfortably do 3D?? I looked at this plane and the sbach and i prefer this one cause it weights a bit less. |

ORIGINAL: Night Scream Hi: I have a turnigy 26cc [though it says on the box its a 32cc ] from hobbyking that has a displacement of 3.0hp. Will this be enough to comfortably do 3D?? I looked at this plane and the sbach and i prefer this one cause it weights a bit less. I get about 7850rpms with a Hawk 19x6 prop on the JC EVO. This is from one of the reviews (from the Turnigy engine)...prop 18x6 @ 6800 rpm @ 100m etros (thats low) the JC spins a 18x6 at 8500+ once broken in. If I were you I would put the engine on a test stand and prop it to about 18x6 and see what you get, if you can get about 7600-8000rpms (or about 15+ lbs of pull) then your in luck. If not then the engine may only be good for sport flying. <br type="_moz" /> |
RE: RedWing MX2 Build
Hey Guys - I've been very busy the past few days, but thought i'd give my impressions on the engine quesiton real quick
When I was choosing engines for this size plane, the easy choice would have been to go with the DLE, becuase the 55 had been getting very good feedback and there was a lot of excitement about the 30cc coming out/newly out. I did not just do so, but instead researched a few engines. DLE JC MLD CRRC I settled on the JC 28cc, for these main reasons - price, quality, power, weight, ease of use, reliability. The JC pulls around a 10lb plane like a rag doll. Does a 12lb plane ok (for 3d). The weight is NOW lighter than the DLE. When DLE switched to rear carb due to their issues with the side carb, it went from about 39 oz to currently 42 - 43 I think. they added an insulator and more metal to the backplate. Whatever the weight is, I weighed both side by side and the dle (both with all parts, standoffs, spark plug, ig, muffler etc) and the JC is about 1-2 oz lighter now. Price obviously beats it, by about $50. Ease of use, starts easily (once you get fuel fed to the carb... MANY new engines are hard to prime, but once it got fule up there it was VERY easy to start and every time since). Reliability - I've not heard of an issue. Warrantied in the US by Henry at RC Aero www.rcaer.com DLE - I sell them. I've sold almost as many as the JC. I offer them, only beucase people still request them over the JC. but you can see my opinion above. The mld was ok, though I hit major snags along the way. Cracked hub (still showing up in their prodcution today!) the sparkplug boot leaks RF noise badly. Power was not enough to really 3d a 10lb plane! It SLLOOOWWWLY pulled it out of a hover. CRRC - I didn't get anywhere with this one. Just not enough RPM and had other issues. Did care for it. LIGHT. That was about it though The Turnigy seems to be light, but I don't know that it would be great for a 3d 10lb plane. It would probably SLOWLY pull it out of hover. Reliability - I've heard very mixed things. Hope this gives some insight to my decisions for finding a match for 30cc sized planes. Get out there and FLY guys!!!!!!!!!!!!!!!! :) |

I did work some on the MX yesterday and today. In between many interruptions for one reason or another I was able to finish the empennage I ran into a small snag when I found out there were two ball links missing from the kit. No big deal I though and proceeded to replace with some Dubro 4-40 ones. To my surprise I found that the supplied ball links are extra heavy duty and much wider than Dubros. My solution was to shim the Dubro ball links with a pair of #4 washer on each side of the ball. I could have swap them for the ones I had installed on the arm end but it's the same thing anyway.
Installed the tail wheel, the main landing gear and the wheel pants. By the way I added #6 washers and lock washers to the landing gear bolts, and #4 washers and lock washers to the wheel pants bolt in addition to using LockTite. A little extra security. The tail wheel installation doesn't explains to well on how to mount the ball link that the guide spring rides on. I screw a 1" piece of 2-56 threaded rod into the ball link and drill a taped a hole in order to securely glue the ball link to the rudder bottom. I found there is not much plywood to install my EMS switches so I had to fabricate some 1/16" ply additions where the switches could be fitted. I like to know how other folks have been installing their switches. I am almost done with the exception of the fuel system, the rudder servo and battery system. I may have to wait several days until I get my new batteries and the BatShare. I should have them not later than next Thursday. If I don't by then I may try to maiden it with a single 3300 mAh battery I have on hand. |
RE: RedWing MX2 Build
Hey Raf. I found that on Sunday evening RCU must be doing maintenance or something on the System and the pictures come out to big. If you delete them and re upload them. They should come out the right size.

RE: RedWing MX2 Build
You're welcome.
BTW. Its looking good.[sm=thumbs_up.gif] Get that thing maidened by Friday. I'll be around till then. |
RE: RedWing MX2 Build
Raf,
Let me know when you are doing the maiden on this one. Want to see it perform as I am interested in this size plane. Mike |
RE: RedWing MX2 Build
I hope to have it ready before next Thursday. I will let you and Bob know as soon as I know for sure. BTW are U guys flying tomorrow?

I found out there were two ball links missing from the kit Finished the switches, the fuel system and the radio installation. Everything proved to be very straightforward, no surprises here. The only one additional thing I added was some fuel line barbs to the provided tank, just a precaution. I will be trying for the first time the new Wike R/C Ignition Battery Eliminator Filter from Try Built Models in conjunction with a SmartFly Batt Share. I will be using two 1100mAh LifePo4 2S1P's for an effective capacity of 2200mAh. I know this setup does not have that much capacity but it will save me a lot of weight in addition to providing battery redundancy. I may need to charge the batteries more often at the field, but the advantage of the A123's is that they can be fast charged at up to 5 amps. I was thinking of balancing the plane with the 3300mAh battery I have on hand but decided to rather wait for the LiFePo4 packs that are on the way. The 3300mAh pack is a NiMh and weights around 10 oz. versus 5 oz, with the LiFePo4's. In the meantime I'll entertain myself installing the fine set of decals Tim sent me. |

RE: RedWing MX2 Build
For the cost of the one of the new 30cc gas engines already in the market you will do yourself a disservice if you don't go gas. There are so much easier to operate, cheaper on the fuel expenses, extremely reliable and more powerful than glow. In any case Redwing models, contrary to other manufacturers that designed gas as the optional choice, are designed with gas engines as the primary type of powerplant. Consider putting a loop in your vent fuel line. The fuel will run out on down lines. Good luck, Darrolair |
RE: RedWing MX2 Build
I have nothing but good luck so far with two Wike ignition cutoff units. They work as advertised. I do have to remind myself that turning on the radio means the ignition is ON. That means I switch receiver on, throttle to full, receiver off, choke on and flip to prime. Receiver on, throttle down and flip start.
Regarding glow being more powerful than gas, it's hard for me to confirm. I had my OS 1.60 converted to gas by Antique. I can honestly that glow is not any more powerful, especially with all that weight. The muffler for my OS 1.60 on glow weighs more than the ignition unit and battery combined. I will re-examine the rpm's I got on glow and now on gas. In the air, it is as responsive and as powerful on gas. |
RE: RedWing MX2 Build
You can put the ignition cut off on switch on your radio. I have mine on the Gear Switch on all but my P-47.
I don't understand what good an ignition cut off is if you have to turn your radio off to kill the ignition. |

I am practically done with this build. This morning I spent some time tidying up things. Drilled a hole to fit the IBEF LED indicator next to the ignition switch. Finished the gas system by installing an anti-siphon line from my vent to a bulkhead adapter on the bottom of the fuse to serve as the overfill vent. On the photos you may note the orange shrink wrap of the IBEF next to the fuel tank. On the third photo there is view of the bulkhead connector for the vent line. The fourth photo shows the additional Hangar 9 inline fuel filter on the carburetor line,
I may wait to place the decals on after the maiden flight. In the meantime I am just waiting for the batteries to arrive. |
RE: RedWing MX2 Build
Lookin good! You are a lot more meticulous than me, the bulkhead adapter is a nice touch[8D]

RE: RedWing MX2 Build
ORIGINAL: AirTech ORIGINAL: T3beatz Lookin good! You are a lot more meticulous than me, the bulkhead adapter is a nice touch[8D] Which type of filter ar eyou using from the tank to the carb? Cause i have 2 filters in my gas tank prior to filling my airplane's gas tank. I use a glow filter before the clunk in my gas tank before passing throught a car paper style filter then to my plane's tank. |
