my original idea was the UMS 90 and it fits with no mods except the spacer then I found out that they were coming out with the 125 so I waited...it does need cowl mods but Iím willing to live with it

Thanks
Mine is running up to 120 deg C. Good cooling with own 3D printed FAN.

I had to cut the firewall with about 1 inch and I did made baffle, thats it!

Sorry the 3 view and spec's on the web site is wrong. the 115cc 3 view one says 260 mm while the specs say 230mm so 5 mm between the engines if I go off the 3 view, maybe a phone call is in order.

Have you canned the idea of using the 125-5 cyl? I am still thinking of using that engine, but not so keen on creating the 'bubbles' for the rockers to make it fit. My other alternative was the FG90 Saito, but I think it would need to be at full tilt all the time, which doesnt please me...

yes I am still going with the 5-125, I havenít worked on it over the last couple of weeks with fly ins over the last 4 weekends in a row. One more to attend in Americus Ga and the build season is on full bore. Iíve seen quite a few Saito 90 out there and I agree that on this model the engine would be at full power most of the time. I met Tim in Rosewood Indiana a week ago and saw his white 190 fly with the DLE111...it was awesome!!

One other option would be the DLE120cc as its the same size as the DLE111. I have two engines new in the box( DLE120 and a GT-80) but I had hoped I could find a Radial 4 Stroke that would fit within the cowl. The scale outline was done really well vs the full scale aircraft. TopRC did a outstanding job on this airframe and adding the sound of a big radial would be a big plus. So it seems the best option for that is the Moki S180 which is out of stock right now.

I am leaning towards the 125-5cyl, simply because a Moki 180 is darned expensive and I also think that that motor deserves a better plane than this. Dont get me wrong, the plane is nice, but the tail section is very weak just before the empennage....very soft, and a point of failure if you chuck the thing around wildly. Its not my intention, but it happens...tight loop or something..

The plane has currently got a GP88 in it, and I am going to test fly it in this config first, to see if its a keeper. By all reviews, it seems to fly nicely.

Question: Has anyone tired to widen, or increase the diameter of the cowl a bit? maybe cut it in 3/4 places and add just a mm or two of material, and get the diameter your looking for? I know it will make the cowl seem a little big but it might be an option. I have a cowl spare so the one thats on it, might have to undergo some surgery as a trial...

I found a build thread on another website where a guy increased the diameter of his cowl by splitting it at one point, and then simply 'opened' it wider, and used some heat to take out the tension in the resin, then he simply F'glassed the strip in, and repainted. The Gap he has was over an inch and it looks ok, I think I am going to go down that route as a trial, since I have a spare cowl...
The idea of the blisters is a good one, but I am concerned that the cowl will be really difficult to remove and put on all the time. Given that the rockers will need regular maintenance, I would like the cowl removal/replacement, to be as simple as possible. I am also aware that the wider cowl might look a little 'off' scale, but I think I would prefer it than trying to cut and fit blisters and then trying to paint match them...

Is putting links to other RC sites a no-no here?
