I have a 50cc MX2 on the way from Valley View RC and hoped to find a build thread. Has anyone built and or flown the mx2? Any mods. required? Thanks for any info. Jim

I have the Goldwing 30cc MX2and love it. I think it's safe to sayGoldwing builds em light so the usual beefing uparound the firewall, gear area etc is needed aftersignificant time on the airframe.

Will also be ordering the 50cc size from VVRC in two days (payday)! Won't be outfitting it for a while though, just broke the bank finally getting my 30% Sbach up and running.

I have the 50 size 3d version on electric 6s 130 fights on it now....

The spats are pretty shot, unless your strip is very very smooth would leave them off....

The firewall/under carriage has a minimal ammount of glue.... my gear came off on the 7th flight (partly my fault) but with more glue it has done hundreds more flights now.....

And the plane is very lightweight and fragile...

Does fly well though I do like it.

you made a good statement regarding light airframes..I am planning for a redwing or goldwing ,,just havent decided but I will beef up critical areas.like pinning the firewall etc.but I like that lightness especially for 3d.

Thanks to all responding, I started assembly of my 50cc goldwing MX2. I used the supplied drill template to install my engine and after bolting it in place found the shaft extended 3/8" too far past the cowl and since the cowl ring does'nt allow adjustment I cut the standoffs back 3/8". Now the carb and choke linkage is binding against the firewall. I ground out enough for everything to fit,replaced the engine and mounted the cowl. The length was fine but the shaft was 1/4" too low. Wish I had caught that the first time. Removed the engine and mounts,plugged the mounting holes with short lengths of dowel and epoxy,cut 1/4" off the top of the supplied template and redrilled the holes and ground the triangle stock behind the firewall at the top to allow for flat washers to fit flush with the firewall.......Don't get me wrong the construction seems great and it looks fantastic I just wanted to warn others to check their cowl engine fit before drilling and they won't have to do it three times like I did.....another possible problem I found is when mounting the servos in the stab the rib is balsa and I put plenty of ca on it to harden it so the screws wont vibrate out. Hope this helps someone. Jim

Thanks for the heads-up. What engine are you installing? I have my Goldwing MX2still in the box and will be planning on a DLE-55.

On my last 50cc plane I found that the prop shaft was not centered in the cowling cutout hole either (by about 1/4"I think), and I used the supplied DLE-55 engine mounting template. I double checked with my own template and it was the same. The factory drawn crosshair pattern on the firewall seemed to be right on as well after mounting. I wound up breaking the wooden ring off the fiberglass cowlpretty easilyand then slightly repositioning the ring andregluing it back onto get a perfect centeredfit. It was really a lot easier than it sounds.The plane isa 30%Sbach and my thrust issues seem to be just perfect but it does have me wondering now.

I have a DM55 a DLE or DA clone. Same mounting as your DLE. My standoffs were 2-3/4" I cut 3/8" off to make them work . Jim

Thanks for the link it explains a lot. Diffrent name 3 yrs. later and still the same mistakes in production or design. Thankful they aren't too bad, the plane looks like a winner. Guess I'll see when mine flies..... Jim

I now have 6 flights on the MX2, It rock solid flies very light and lands very slowly and will take a steep glide angle if you want (great for landing approaches over treelines) and does'nt pick up a lot of speed. I am not a 3D flier but I think this is a great 3D machine. I need more flying time to learn how to fly like I want. One of my favorite manuvers is a snap on top of a inside loop. With the throws I have on elev. rudder & airl. when I cut power on top of the loop and fully deflect the surfaces it does about 1/2 snap and just stops in the air and falls . No airspeed. I also does the slowest spins of any plane I have owned,this without adding power and they are almost flat. OK i like it! Unless you spend a ton of money you will have a hard time beating the GOLDWING MX2 Thanks to everyone that responded.........Jim

Just got mine on sale for a great price. I'm working on the build, any advice would be appreciated. This thing looks awesome, bet it flies great as well.

Got any pics, I just love these GW MX's

jcoop65

where is a good source for standoffs. Im installing a dle 55 and i need to lose 10mm in length for proper fit. I really don't want to cut the ones I have. Does anyone have pics of where they beefed up the firewall and landing gear?

I dont know anyone making cut to size standoffs but if you cut yours to fit and you need the standard size later you can buy replacements from tower later or add the correct size plywood or barstock alumn. spacers. As for L/G reinforcement picture I dont have a camera,however, I used triangle stock in the pipe tunnel and tank area.I ran plywood as reinforcement veretically 1/8" or smaller if handy to reinforce the former at the front of the tank and a piece across the bottom lip at the top of that former. You can see 2 screw heads holding the gear alumn. brace on each side I used triangle stock vertically in this area 4 pcs. total for the 2 sides, use plenty of ca in the ends to harden the balsa tri. stock. You will probally only gain a couple of oz. in weight but I feel it will keep the gear from ripping the belly out on a hard landing....Maybe someone else has a better Idea or some pictures they can share on how they did it. Good luck.........Jim

Build is going good. Started the engine sunday,this plane is going to scream,

The main thing I would do is replace the fuel tank, and fuel proof the tank area.
It seems the screw on the tank like to work loose and starts leaking. mine has done this twice, with the last time was this past weekend. It got my former behind my tank and stringer really wet.
The landing gear formers are really weak and many guys have knocked the gear loose on even the slightess bounce. To prevent this I cut the covering on the belly right behind the rear landing gear former and fiberglassed the former followed by laminatening it with1/16 lite ply. and then wrapped glass from the LG block to the former. I also did this to the front LG former. This made my lg very strong and it has taken lots of abuse.
I also reccomend using automotive fiberglass on the engine box too.

jcoop65

Kerwin, Looks like the 30cc version. Ive heard about the landing gear issues on older versions. I also have added reinforcements to my lg and im going to do the same to the engine box. How many flights do you have on your airframe? Im still in the process of setting mine up but i really appriciate your advice, cant wait to get it in the air. John

kerwin50

Yeah it is the 30cc version. It's the V2. I've had it flying since spring.
It has become one of my favorite planes.
I'm sure that the 50cc version will be much the same if not better.
