Looking good Kelly.

Now hurry up and finish that baby. I need a flight report! I still haven't decided what I'm going to do with my DA70.

I'm getting anxious too! Got some neat electrical connector mounts (for the XT60's) and a hard case 4200 mah lipo coming for it. Should be here Thursday. The battery will be mounted in the pipe tunnel and feed two connector mounts. One for the receiver/switch and one for the ignition control. The install will be one of the cleanest I have done so far.

Those XT60 mounts look pretty cool.

Kelly, why the hard case pack? Seems like a lot of extra weight no?

At first Mike the weight was a concern but compared to a non cased lipo of same capacity it is only about three quarters an ounce heavier. My main reason is the way I am going to mount it!. Just going to have to wait and find out.

Well...I think I have the engine installation all complete and to my liking with the exception of baffles. Will trim the excess HT RTV once it dries (less messy). I added a support to the muffler (I use this term loosely at the moment )because I could get it to move up and down a bit when bolted on. This should help relieve stress at the bolt flanges from vibration.

@ghoffman Can you make me a set of your baffles for this cowling if I give you the general rectangular dimensions of the openings and distance of L&R cylinders?

Plane is not designed to break the "sound" barrier....or is it???

Will you have enough back pressure for the engine to run properly? I don't how much is enough, but I do know they have to have some

Hopeful that the elbow will allow enough. If not....... Cant get a large pro flo in this plane. So this is plan B.

 

[49dimes]

Oh!......Nall contribution for above. And FWIW..... If back pressure is an issue then I can experiment with some inserts in to the Teflon coupler.

Have you test run the engine yet dimes? That thing has got to be loud!

Hey Dimes....why not use two 45 deg elbows, one angled up to the rear, and the other to straighten it out back into the tunnel?
