Zeroing In

So, I now think I have the zero sorted out although I may not be able to resist the urge to do some more tweaking.

So, here is a summary of what has been done, and what effect it has had:

- Painting underside of wing white to try and improve perspective on plane - worked (still difficult at distance so need to pay attention, but it does stand out a little more, and in my opinion that plane looks better too with those red spots on white wings)
- Upgrade to EPS400 Class Powerplant - after the nosing in the Zero when losing perspective on it, rather than replace the EPS350 gearbox (which was smashed up good) I put in an EPS400. This helped move the CoG a little forward, but was "useful" weight because it's a bigger engine.
- Finally have decided that for both the EPS350 and the EPS400 the 9x7 is the best prop.
- The tracking issue through loops has been fixed by using some double sided foam tape (with the backing left on one side) to push one of the wings down slightly so that its angle is more like the other wing (Thanks Paul@nitrodude).

Getting in heaps of flights with the zero. Landing her on rough grass results in nose over even when you do a good landing unless you are quite lucky. All the same, am getting the landings much much better.

In other news installed the servos and control linkages for the RV4 - she is getting very close to being ready to fly. Had a long chat with Paul yesterday about power plants. Looking at either brushed 400 or some kind of lightweight brushless system. Both have disadvantages.

Later.
