Question
DA-50/DLE-55

Does the DA-50 have the same bolt mounting pattern as a DLE-55 rear exhaust?

Thanks,

Tony

the dimensions for both are available through the DA site and DLE site respectively. the quick answer is no.

I cannot find a website for DLE. Also, I am asking about the DLE 55 rear exhaust, not the RA. I only see the mounting dimensions for the DLE55RA on Tower and Horizon.

The rear exhaust is the RA. Otherwise the 55 is side exhaust.

Is the RA a newer version of the DLE 55 rear exhaust?

there was never an old version. There are two 55ccs...the 55RA rear exhaust and the 55 side exhaust.

Ok thanks. Never had a DLE so don’t know anything about their lineup. It looks like neither version has the same bolt pattern as a DA50.

having had both, I can tell you that that is true. let me know if you need any help aligning the engine. you will need a metric ruler.

Thanks. I will using a DA50 but the plane is marked for a DLE. It also has alignment marks on the firewall so it shouldn’t be difficult to center it. Thanks!

Another question. I was looking at the instructions for my TF FW-190 and there are marks on the firewall to mount the engine. A DA-50 and DLE-55 use the same marks. However, when I looked up the specs for the current DLE-55s neither has the same mounting dimensions as a DA-50. That makes me assume there was an older DLE-55, the FW-190 instructions are from 2012.

The DA 50 and the older DLE 55 side exhaust, are close but not the same mounting holes. If you use the DA holes for an older 55 the engine will be slightly offset. Not sure how you got the idea they were the same.

I am just telling you what the instructions say. I installed a DA50 using the marks on the firewall that Top Flite said were for the DA50 and DLE55 and the DA lined up perfectly.

that's because it's a round cowl and doesn't have a spinner circle on the cowl. a slight offset isn't noticeable. but they are definitely not the same as a few moments of research will show.

I appreciate your help but maybe I didn’t explain myself very well. I do not know the DLE lineup at all, I never owned one. I was trying to find out if a DLE-55 is the same as a DLE-55RA. I thought the point of these forums was to reach out to fellow modelers for assistance and sometimes clarification. I am sorry to bother you.

well, I can only do so much. I have already explained to you that the DA 50, the DLE 55 side exhaust, and the DLE 55RA are all different mounting patterns. You may think otherwise. There isn't nor was there ever a 55 rear exhaust that wasn't an RA. the 55RA dimensions are below. It is not the same as the side exhaust 55. All of this information can be found through Google. Don't be offended.

The DA 50 is close to but not the same mounting pattern as the DLE 55 side exhaust.

the DLE 55 side exhaust mounting pattern is completely different from the DLE 55RA

DLE has a comprehensive website with the dimensions/specs of all their engines, but I keep getting a warning not to open it. I hope they get it resolved because it is a great resource.
