I made it to the flying field yesterday afternoon. There was a club meeting in the morning that I missed because I was originally going to be flying back from a work trip yesterday morning. However we thankfully finished a little earlier than expected and I got back late Friday night.

I took the generator with me so I could charge the 6S packs for the PROTOS. I got 2 flights each on the DeJaVu and the PROTOS.

I worked on a few maneuvers from the Sportsman sequence and also the proposed Intermediate sequence for next season. A part of this was flying faster and further out. As a result I burned about 8% more of the battery on the first flight. On the second flight I was having a little trouble with some of the maneuvers to I brought it back in closer to work on them. I was worried the Outside Loop was going to kick my butt but I got through a couple of them. Not the best loops but I am also just starting to learn the sequence. I meant to take my stick plane and a print out of the proposed sequence but accidentally left them at home.

The 2 flights on the PROTOS were nothing great. Just getting used to flying a heli again after a little bit of a hiatus.

I also managed to find the tire to my tailwheel that I lost the day before the local pattern contest so that was a plus. It also survived the field being mowed!

While on my trip last week, my replacement generator arrived. My original seems to be doing OK so I'm going to put some oil and fuel in this one to run out any possible pump gas in it and make sure it is OK for storage.

I am back at the airport right now but I'll be back mid-week from this trip thankfully.

Kind of a crappy weather day which means fall weather is beginning here. While taking care of stuff around the house, I put oil and fuel in my replacement generator and ran it for a while.

Well, assumptions are truly a pain in the butt...

I got the DeJaVu up on the bench to look at the elevator servos. I've been thinking about this some lately and I started by taking my calipers and measuring the pushrod lengths. I don't know when this occurred since this was a plane originally owned by someone who competed and won at the Nats but one of my elevator pushrods is longer than the other by about a 1/4". On low rates there isn't much effect but there is when you go to high rates.

I have not had to use high rates yet though.

So next steps will be to adjust the linkage and redo the elevator subtrim and end points.

While up on the bench I also noticed some fuse damage in the gear area. I'm sure this has been there since I bought it and the gear plate is still solid. So I will probably leave it as is for now and start looking in to composite repair.

Doh! Seems like a simple enough thing to fix though.

Yeah, I'll work on it tomorrow since it is supposed to be windy.

So yesterday I ordered some new vinyl for the EF Edge. I decided to get an EME Engines logo from B & E Graphix. Not 100% on what I ordered but it was the best I could come up with at the time. I'll either put it on when I see it or I may just order something similar after I play around with the colors some more.

I also started working on the pushrods for the DeJaVu. I realized today that the ball links are glued to carbon rods. I am going to order the same ball links and then get some kind of adjustable metal turnbuckle style pushrod to replace.

Well the F3A world competition is getting up and running. There have also been interesting designs in these type of aircraft. Some are OK but some are down right odd. This is Gernot Bruckmann's latest.

Thats truly Bizarre

But fantastic looking. Kind of like a modern F1 car. Form follows Function

You took the words right out of my keyboard with "form follows function". Very much like how all modern DLG designs pretty much look identical. Once you start designing for a specific task (or rule set) things all tend to look the same. But this.... yeah, this is very different!

I finally got off my arse and did something RC related this evening. We have a club meeting tomorrow and I plan on getting a few flights in afterwards.

So tonight I worked on putting on the EME Engine vinyl I purchased. I have a system where I use some basic tools that can be used to measure the middles of curves and make reference points to get a good application. Rapidtac and other solvents that allow you to re-position the vinyl help.
