Ordered my Su-26

Sounds like you have it figured out.

Hope I'm not to late. Be sure to mount the Cowl with the Canopy on. That is what keeps the Cowl round and where it belongs. Sweetpea also warned me when I was building mine not to start the engine with the Cowl on unless the Canopy is on... Never seen it happen but he said there is a chance that the cowl will crack from the vibration.

Thanks for the advice Tom, you are not to late and I did read the post sweetpea put up about cranking the engine. I was a little surprised to find out that the DLE-61 weights almost 1 pound more than the DA-50, I didn't think there would be that much difference.---Smitty

I wouldn't worry much about that 1 lb. I'm sure my 58 is about as heavy as your 61.

I am going to keep that 6 3/4 distance from the firewall to prop hub.--Smitty

Have all servos in the flying surfaces. Got the pull-pull cables done today, I was surprised at how good they turned out, I usually don't do a real nice job on those but this time I think I did good. Have all the switches mounted. Temporarily mounted the engine with some makeshift spacers to get a idea on how the cowl will mount. Using the 6 3/4 measurement that Tom set his engine from the firewall, it seemed to me that the engine stuck out too far from the cowl. I am going to play around with the spacers and try to get the engine about a half inch from the cowl to the backplate of the spinner, unless someone can tell me why not do that. I only have about a inch of cowl fitting over the hatch. Boy it sure is looking good. From the way the engine sits now I don't have to cut any of the firewall away for the carb, I have about a half inch from the carb to the firewall. Here are a couple of photos .---Smitty

Yep...don't run the engine cowl on hatch off. Highr throttle isn't bad but the idle can shake and chip the paint

Hey Tom I see you are on the forum right now. I have a question, I needed different length of standoffs than what came with the DLE, which were 3 inches. So I ordered the set from SWB that have a couple of different size spacers, only problem is the are drilled and come with 1/4-20 bolts now the DLE mounting holes are in mm I guess either a 5 or 3mm. What would you do, 1- Drill out the engine mount to accept the 1/4 inch bolt or put the smaller size mm bolt in and have a little slop in the spacers instead of a snug fit. I am leaning towards drilling out the engine mount. We are only talking about maybe 10 to 20 thousandths.---Smitty

I have drilled out several motor mounts without any problems. I know of friends of mine that did the same without any problems.
However I'll let you make up your own mind on this one.

For what it is worth, and just my opinion. Drill the motor mount. I've had to drill a number of them and I've had no problems. The amount you take away from the motor mount will never impede the structural integrity of the mount itself. The upside is that it is much easier to find or obtain bolts once upsized.
