Another RedwingRC 30cc MXS-R Build

Almost done with my RedwingRC 30cc MXS-R. Just wanted to get this thread up and get the pictures on here real quick. I will update the thread with a full explanation and my thoughts on the plane.

Thanks!

EDIT: So here's the deal. This is my first gasser, been flying up to 60 size nitros and nitro helis for about 2 years. I was looking for a few weeks trying to decide. I was looking for something decently priced as well as something that would fly and land very easily. After much debate I finally settled on the RedwingRC MXS-R 30cc due to several recommendations and what is included for the money.

RedwingRC 30cc MXS-R
DLE-30 w/TBM Throttle/Choke Arms & JTEC Pitts Muffler
Single 3000mAH Redwing LiFe Battery with Wike IBEF for the Ignition
3 x Align DS810 (Airlerons & Rudder)
2 x HiTec HS-5965MG (Elevators) I had them laying around
1 x Power HD 1501MG (Throttle)

My initial impressions were pretty good upon receiving the plane. It shipped 2 days after I ordered it via Fedex so I got it pretty quick. Overall everything seems well constructed and the quality of the parts is pretty good. I was especially impressed with the carbon landing gear, it seems better made better and stronger than my Great Planes Reactor gear from GraphtecRC. Covering is applied fairly well and seems pretty decent. The cowling is very nice and sturdy. The servos trays in the wings come with aluminum L brackets as well although I did have to enlarge the servo arm slots to get proper travel. Carbon wing/stab inserts and wing/stab tubes.

A few things to mention:

The wheel pants have to be modified a bit to fit(mine did anyway). I had to adjust the hole placement and lengthen the wheel slot on one of the pants and I had to enlarge the axle slot on both. The pants are a little thin, but they are fiberglass.

The fuel tank is decent, but I elected to replace it with a dubro 12oz with new plumbing. The tank can be used without a problem and come pre-plumbed, but everyone has a preference on the fuel supply.

I had a hell of a time getting the choke lever setup. I finally placed it as shown in the pics. Not the easiest access, but it works good given the hole placement of the MXS-R cowling. Keep in mind this is my first gasser so it's my first choke setup.

I did have to use some 1/8" thick nylon washers between the standoffs and the firewall, as well as 3 thin metal washers between the standoffs and the engine to get the prop hub out far enough. No big deal, but I thought it was ready to go for the DLE30 other than drilling holes.

I also used my own hardware for the throttle linkage(turnbuckle and ball links) and MPI metal servo arms all around.

Overall I am very happy with the purchase and especially pleased with the customer service. Not always the fastest response as they are very busy, but Tim will get back to you in a timely manner and will do whatever he can to make sure you are happy with your purchase. I sheared the tailwheel bushing? off somehow and Tim quickly sent out a free replacement. So far I would definitely do it over again, now I just have to see how it flies.


So with that out of the way, I am almost done with the build. Sealed the hinges and did an initial balance, I got lucky and it balances perfectly at 5" without moving anything. Just waiting for the spinner bolt to come in to do the final balance. With this being my first gasser, do any of you guys see any issues with anything I did? I plan to replace the zip ties on the ignition with velcro straps sometime soon, probably after the maiden depending on the weather...

Anyway, I think that's about it for now... Thanks for looking!

Thanks guys. Went out today and bought a tonneau cover for my truck to transport it. Now I won't have to fear doing 80 with this thing in the back. If all goes well and I get the spinner bolt, I may do the maiden sunday. Supposed to be nice weather...

Gutzy, I was looking at some pics in a thread on here, forgot which one though. Anyway, you had posted a pic of your garage and you had a red and white plane in there with a crazy cowling. What was that? Looks pretty sweet.

By the way, I edited the initial post if anyone dares to read that much rambling...

DustinB- Your build looks great! Going gas is the way to go, once you here the noise from that 2-stroke, you will be happy you did.
The other plane in my garage is a 80'' Nemesis. It was my first gasser. It's made by SeaGull and it's a POS. The thing just falls apart when flying. And on top of that it's a pig. The Syssa 30 tugged it around fairly well, so I'm stoked to fly it in the MXS-R, which is 3.4 lbs lighter than the Nemesis.


Good luck on your maiden, wish the weather was better up here, oh well, one more month of misery.

Well I almost had a chance to maiden it, but luckily I waited too long helping someone get their glow engine running and the winds kicked up. I was checking the CG by taping the canopy on the wing and tying a string on the inside framing, apparently this didn't do the trick. After making a balancer I found out I need 2 oz of lead in the tail to balance at 5-1/4".

Anyway, I thought I would post some pics of what I have been doing to it, I decided to make some logos for it since my girlfriend bought a vinyl cutter. Anyone have any ideas of what I could add to this? The underside will be fairly simple, I remove the silver stripes and am planning on cutting some swaying checker patterns. One color for each wing with the red showing through.

You will need to open the hole at the engine or it will run hot. Mine did. Opened it up just to the edge and it cured the problem.

Thanks guys. I finally got to do the maiden this weekend. Only took a couple clips up and left trim. Very docile, not twitchy at all with the recommended low rates and about 25% expo. As for landing, holy crap, this thing just floats forever. I had to fly at half throttle and cut it before my final just to be able to slow down and touchdown halfway down the runway. There was hardly any wind though.

I was able to get in 2 flights yesterday and 3 flights today. I have been running into engine problems though. Yesterday, any time I would roll left or right to turn, the engine would richen up and bog down. I did the vent mod last night and ran the tube into the lower part of the fuse. Flew it again today and it wasn't nearly as bad. It only happens when I pull up or turn moderately, light turns it doesn't. I'm kind of at a loss on what to do. I tried to lean the high a little more, but I am right at max RPM very stable at WOT with no burble pretty much anywhere. Great transitions.

I'm starting to winder if I need to try the pitot mod I have seen on here. This is a DLE30 V2(rear carb). Anyone got any ideas? I would like to get it running right so I can actually try some aerobatics and comment on the performance of the plane.
