Yes, it is Messchersmitt. It is something between Bf-109F and Bf-109G. I´m going to remake it to Bf-109G. I´ve just had one, but during the first flight I had problem with the engine []

Today was the last day of painting. Now is also painted the tail number, which I made different. Number 72 is easier than number 79. Now is time for cockpit. I bought the ESM Japan pilot 1/5, because the 1/6 one is too small. I don´t know how it is possible, because my Zero is cca 1/6. Maybe it caused by the different producers, Zero is from CMP and pilot is from ESM. Last thing, which I made today was exhaust system.

Everything looks really good there. I found the same problem with some of those figures as well...did exactly as you...used the 1/5 instead

In today's times it often seems that people go around or avoid the real truth to describe their actions...from the simplest to the most complicated. You very plainly said you did what you did because it was "easier". That was straight to the point and honest, no apologies or strange reasoning. Very sincere and refreshing to read since I hear so much BS in a day. It made me laugh because of that and I was very happy with reading your post
Don't overthink my comment...It is definitely meant in a very complimentary and positive way! And yes, a "2" is much easier than a "9", that's part of what amused me since I've done the same thing for the same reason (53 instead of 58)
Love your progress and the pics. Keep them coming.

RE: CMP 120 Zero ARF Build thread
Hello to all who participate on this building thread. I have been reading this for a long time and now i finaly hade the oportunity to buy one of this ARF´s. I´m in the point of have to chose the components for my plane so first of all:
For the engine i have got two options a ZG26cc that i have converted for EI with RCxell parts and a well tuned Ryobi 31cc (so fa i have got so far 8700rpm with a 18x10 prop), from what i have read this plane needs a lot of weigh in the front so probably the Ryobi will be better. I have seen some of them flying with this ZERO also here on RC Universe
The retracts.... so far i´m thinking on electric retracts so if some one of you is using them please just put a link from were you buy them and also for the struts because i have read from one of you this store (http://shop.rcskylite.com/products/6...o-Fighter.html) has one set that it says that are for the ZERo but will they fit on this particular plane? i would like to know because of the size of them......they look small for this plane!

Hello erec,
I have experience with the Zero 50 CC. But every CMP Zero needs a lot of weight in the nose, so the better choice is probably the heavier engine. For my bigger Zero I used pneumatic retract for the ESM La-7. Maybe you can compare some ESM retract, for example Ki-84. I don´t have any experience with any electric retract, so I can´t help you with this question. CMP models don´t have scale length of the legs and diameters of the wheels.

erec11, I have Zenoah 26sc with magnetic ignition (lot of needed weight at front) and it came at 8.5 kg empty. Till now it has only 3 fights,
because it was finished at the end of flying season, but for now engine has enough power.

Yes i have the 1800mm Zero, so because of the weigh i belive that the Ryobi it will better.... the only problem is that i can´t start that engine by without a starter but thats ok! And for the electric retracts anny news?

RE: CMP 120 Zero ARF Build thread
Yes, I know, that he has the smaller one.This is the reason, why I recomended him the ESM retract for Ki 84, and this is the reason, why I bought the retract for the La-7 (it is bigger). Iwrote, that every CMP Zero needs a lot of weight in the nose, I thought every Zero of every size, not only Zero 50 CC. I wrote, that I have experience with Zero 50 CC, so I want to tell him, that I haven´t the same Zero as erec. Maybe I should wrote it better.

erec11- Maybe something like this one. Not exactly scale, but nice price.
They are for models up to 7.5 kg.

RE: CMP 120 Zero ARF Build thread
erect11, I have the same plane. Either engine will work but the extra weight of the 31cc will not hurt. I'm using a 25cc McCoughal conversion with electronic ignition. Even though it is heavy I still had to mount both ign. and radio batteries under the cowl and still needed to add some weight to the nose. Total weight of the plane is about 16 lbs. I rebuilt the gear mounts and added flaps. Plane flys great. I'm using Wingspan electric retracts. Here is the link http://www.wingspanretracts.com/LGM685. I had air retracts which were not working good and replaced with these. I have 15 flights on them and so far they have worked great. Using Robart struts 5/16" dia. and 4" wheels.

Thanks for your reply, tell me this how long are your struts? from the top untill the weels shaft. I have seen here some struts with 210mm but yours looks smaller than that. i have found this on ebay and it looks nice but the size....... i´m not sure if they will fit.

RE: CMP 120 Zero ARF Build thread
Frets, I upload some new pictures of my progress. I started with the details in the cockpit: guns and revi. I made it from the balsa wood and PVC (poly vinil chlorid- plastic material). The won´t be scale, but want to have only some revi, maybe I will you revi from my Bf-109.

RE: CMP 120 Zero ARF Build thread
Well now i have two possible solutions for the retracts, one is electrical and the other one is air. Take a look a this two sets of retracts: http://shop.lindinger.at/product_inf...ducts_id=79143 this is the air ones and this are the electrical http://shop.lindinger.at/product_inf...ducts_id=91358.
The price i have to say that both are very nice deals the air retracts cost something like USD50 !!!! yes 5 0 dollars!

RE: CMP 120 Zero ARF Build thread
Finally had some time to make some progress on the second wing half. I had reminded myself repeatedly to make sure to take more pics....still forgot.
Anyway, I must have a knock-off in a CMP box or some older version of the 71"/1800mm Zero because this wing has void spaces in the sheeting and the covering leaves horrible residue when it is peeled off. Comparing parts and things to friends, all parts are otherwise identical to what I see here on everyone elses models.
After peeling off the covering I have to go over the wing with packing tape to remove the rest of the covering adhesive. It works pretty well.
I have a full size (to the model) set of enlargements of the 3-view that I use for reference so I traced out the wheel well and got it cut out. You can see how bad the position and size of the kit is from the tracing.
I cut out the old gear mounts, made some new formers and installed new rails. I also sheeted the bays between formers and the wheel well area with 1/32 plywood for strengthening and because it paints better without too much wood grain showing through.

I added some thickness at the end of the well for attaching hinges if I decide to add the inner doors. Traced and fitted end and curvature formers/stops to the bottom sheeting to help shape the well lining and give me something to glue to. The well is lined with 1/32'' (.5mm) lite ply, The gear leg walls are 3/32'' (2mm) balsa for some extra strength for the gear mounts.

RE: CMP 120 Zero ARF Build thread
Next; The Zero has a very distinctive gear leg, so I have modified my second Robart 7/16''(9.5mm) strut to look better. First the oleo mount is cut off the lower strut and then the strut is drilled for the oleo pin. next it is clamped in a vise, heated and bent. the oleo needs a bit of a relief cut into it for the lower end and the oleo stop on the upper strut has to be filed down a bit for the proper extension. I am using 3 3/4'' (95mm) Robart wheels. I'll use some automotive repair resin (Bondo) on the lower strut later to make it less round and look more like the reference picture.

RE: CMP 120 Zero ARF Build thread
The leg looks very good frets !
2 questions:
a) the drilling of the hole for the lower pin @ the new location of "spring" mechanism, wouldn't that make it fragile @ that point ? or did you weld-glued the pin ?
b) can you share the file for the scale drawing you show in the first picture series, pls ?
Thanks, V.

The steel tube of the Robart strut is a relatively thick gauge and the location of the hole has the added strength of the factory weld for the off-set, also any forces applied would be in line with the hole and not across it so bending should not be a worry
b) can you share the file for the scale drawing you show in the first picture series, pls ?
It is just a copy of the 3-view below. I took it to the photo copy store and made four copies; two normal and two mirror image or reversed copy. Cut one copy of each (normal and reverse) in half along the centerline of the fuselage and tape the half copy over the the opposite full copy to get a whole top and bottom view. Gave the top view and the bottom view to the store keeper, he scanned them into the printer computer and adjusted the image so that the print would be 71"/1800mm wingtip to wingtip and blanked out the fore and aft fuselage that I did not need. Then printed off a few copies. It was just really cool that when the copy was enlarged equally (100%x=100%y) to match the span, the profile from LE to TE was nearly perfect to the model wing also...only the tip is wrong on the model...and not by much. see my aileron post a few pages back and you can see that the tip did not need too much change.
Thanks, V.
