Oh, and another little by-the-by....

When glassing my flaps and ailerons, I gave them a flow coat of resin (thinned with a little metholated spirits) after the initial coat. You may remember that I only did one coat of resin on the rest of the plane and filled the weave with spray putty.

My god what a difference in terms of ease of finishing when it came time to sand and spray the fill primer. Just sanded the resin, then only one coat of the fill primer needed and some small application of spot putty here and there compared to about three coats of fill primer on the glass with only one coat of resin.

For anyone new to glassing I STRONGLY recommend doing the flow coat!

Yes but in my case it's usually something I've had in my hand and then placed it somewhere only minutes before!

Oh yeah I've done that too! Once I was working on my car, put a spanner down then reached for it a minute later. It wasn't there and I've never found it! That was the angriest I have ever been in my life I think

Just thought I'd post a short highlight video from the other day of one of the reasons it has taken me so long to get close to finishing this build... FPV flying is certainly addictive!

Gree,
That is really cool, thanks for sharing. How high were you in the clouds?
Does your system have a "return to launch" feature?

Those clouds were pretty low at 1000m (3300ft). I use a Zephyr II, and have the range video osd with return to home etc etc.


An update to this project - my flaps and ailerons are ready for panel lines. With any luck they should be finished and installed by the end of the weekend.

1000 meters!!!!!!!!!!! The field I fly at we are limited to 400 ft agl.

After my P-47 is finished I think I'll try FPV. I'm not sure if it will be by fixed wing or some sort multicopter as a platform but your video sure makes it look fun.

Flaps Ahoy!

Flaps Ready for Installation
Well my prediction of having all of the control surfaces of the wing attached by the end of this weekend didn't quite come true. I was waylaid installing a chandelier today! So a lot of build time turned into home improvement time. Oh well I'll still get there...

The flaps and ailerons were glassed last week, and over the last few days I did the usual filling and sanding, panel lines and riveting (stayed up to 2.30am last night doing them). I detailed this process before so I won't post any photos of that today. The ailerons only need trim tab actuators made and then they can be given their final coat of aluminium. The flaps as mentioned are completed.

I'm looking forward to getting the flaps installed...

Thanks Chris. In proportion of the time it has taken to get this far, no not long (comparatively!). I installed the flaps after work today, but haven't got the servos hooked up yet. Bloody hell they are finicky buggers to get in the right place. But the epoxy is drying as we speak!


As far as I can work out, I have the following left to do, in no particular order:

1. Make the rear canopy attachment and install
2. Glue the canopy on
3. Make the landing light and install
4. Make the wing tip navigation light interiors and install, plus glue on the wingtip lenses
5. Get a new motor shaft adapter from Truturn. I found out mine has the wrong thread!
6. Make insides of lower gear doors
7. Make insides of middle gear doors
8. Attach gear doors to struts
9. Attach inner gear doors
10. Make trim tab actuators for ailerons
11. Final coat of paint for ailerons
12. Attach ailerons and hook up servos

13. Put on cowl checking that motor is centred
14. Paint tips of prop yellow
15. Paint prop hub yellow
16. Make tail navigation light
17. Work out how to open the battery hatch and make solution
18. Weather the wing etc
19. Make and install the guns
20. Get new 6S 5000maH batteries
21. Balance
22. Find a place to actually fly this thing!
23. Pray hard to a god I don't believe in
24. Fly...

GREY = done!

So maybe a couple of months? But I have heard that before!!
