Status: offline 		I have just purchased one of your kits and wanted to know what stand offs should i use on the engine its one of the DL 50cc engines (same demintions as Da) would the 3" be ok, or do i need the 2 1/2.

What size tires do you reccomend?

Once i get the kit I am sure to have more questions, is it ok to bug you with them?

Thanks for your help.

Status: offline 		Craig, I think I used the stock standoffs that came with the DA50 with no modifications other than a few washers for offset purposes. I don't know what the exact dimensions are though. As for wheels I would recommend 3 1/2" wheels. Let me know when you get the kit and we'll be here to answer any questions.

Status: offline 		According to the plans the engine layout shows 3" standoffs.

Any of you guys that have built this plane care to chime in and tell me what standoffs your using and if you all have adjusted the engine over to the left to compensate for the 3 degrees right thrust. It looks like there will not be enough room to slide the engine to left and still get the bolts in, and the standoffs look as though they would be setting right on the edge of the firewall.

Also what brand of wrap around muffler are you all using I've been using the jtec and it seems to be much larger than the one shown in the plans.

Status: offline 		Craig, on both the ones we built for OMP we used the stock DA 3" standoffs and yes we did offset the engine to the left to compensate for teh right thrust. No problems with spacing at all. Also I used the wrap-around header from DA and the pipe they sell. They make three header offsets if I recall and you need the middle offset header.

I know that the stock stand offs from DA are the correct length. Hope this helps.

Status: offline 		Also we cut a lightening hole (oval shaped) right in the center of the 1/16" ply gear plate and this provided great access for a set of pliers to squeeze and release the hose clamps that connect the header to pipe coupler.

Status: offline 		After looking at the plans I'm thinking i would need the 50mm drop to get the can down in the fuse. Acording to Da the drop is measured from the center of the exaust to the center of the pipe.

I think Da has 4 different drops a 0, 25, 50, and 75mm.

Mike did you use the tuned pipe and header or was it the header and canister muffler? Da said ther is about a 50.00 dollar difference between the two. The tuned system being more. And can you remember the brand that would help in knowing which system was used?


Any body else use this setup?

Status: offline 		Oh and by the way what and how did you make the top of the canister tunnel out of? Did you make a removable bottom under the canister?

Status: offline 		It was the canister setup from DA. Also I did make a removable hatch on the bottom of the fuse behind the gear plate. Just remove the 1/16" sheeting and replace with 1/16 ply with cooling vents cut in it. You can even get fancy on the cooling vents if you want. I glued in a couple of 1/4 sq balsa supports along the edges so that the hatch was recessed and flush with the remaining sheeting. Used 1/4 sq basswood supports in the front and back so I could attach the hatch with small servo screws. Worked like a champ. In this pic you can see the vented hatch on the bottom.

Status: offline 		Keep up the good work Craig and post some pics of your DL and header setup when you get to that point. I'm not sure there is much info on that combo yet and I think folks would like to see how it works out. I know I would.
