Default Build a Miss Ashley - Revisited

The gear length should be between 1 3/4" to 2 1/4" (to the axel). Start at 2 1/4" and verify that there is approximately 1/2" prop clearance when the wing is at zero incidence.

On the second model the wheels did not have bearings. The axels were moved forward and the gear were shortened to reduce nose over during a power push. Full up elevator was required during this style of launch.

I added some tail weight to balance the model at 3 7/8" back from the front of the wing saddle.

The tape was later removed and I plan to use about 0.35 ounces of lead-epoxy mix (the weight of the lead tape used) instead of the tape. This will be installed at the rear of the model inside the fuselage.

The first flights on the Miss Ashley were uneventful. The model needed some aileron trim and some down trim to fly to my satisfaction. I also added some tail weight to increase the elevator sensitivity and quickly turn back on #1 pylon. In my opinion this version of the model, standard long nose, tracked better than the one that I shortened the nose in the earlier thread.

On race day the model flew better than I did and my first couple of races were flown very wide around #1 pylon. An adjustment was made and during the next race the course was better around #1 but I had a midair between #2 and #3 pylon. We must have just barely touched the models as I didn't realize there was a midair until I inspected my model after the race. I was missing half of the horizontal stabilizer and therefore the backup model was brought out.

Both models were fast as any that I raced. Unfortunately my flying skills were not quite up-to-par but I managed to get a 1:10 for an 11 lap race. The good thing is that I managed to finish the Phoenix QM40 Classic and bring home both of my models.

I've continued on my other Miss Ashley. The cutout template was taped on and I used a model knife to mark the location of the cuts.

The template is a big success and it saved me significant time on cutting out the hole. Below are the pictures:

I've been continuing on the second model.

Below are some pictures showing progress on the tail surfaces.

That is a nice looking plane. But I still like the kit built stuff better.

Maybe be I am just old school.
