Thread: At last! Finally got out for a maiden flight
23/09/2020 19:13:15

The point is Peter, while I could do that and I appreciate your suggestion, my charger only charges up to 6S which is what I use to charge my lipos and wire them up in series as a 12S. Hence my comment about the extra cost of new charger and 8S lipos (which I don't have) , that is of course assuming you can source 8S lipos upwards between 6A to 10A. sad

I know Overlander do them 8S, but they don't match the discharge rate on the 6S  10A lipos that I have

Thread: Airborne Battery Pack Duration
23/09/2020 12:52:19

Yes Cuban8 you are absolutely right.

Since turning leccy, most of my flying is done at 50% or 75% throttle depending on what I am doing. 100% throttle only gets engaged when entering aerobatic moves such at stall turn, loop etc. As you say set up is everything. I try to make sure the whole shebang is as light as possible from airframe to motor combo selection. On windy days I reduce the timer warning by 10% which has served me well.

An update after 2hours+ of use and trimming show her to be very capable at aerobatics. I have set all working surfaces at 100% with 20% expo on the elevators and 25% on the ailerons. No formula here just a finger in the air job.

With lipos fixed just behind the main spar the CoG is a tad rearward, but no vices noted. One thing that puzzles me is that while the upright flat spin proceeds normally, when I go into an inverted flat spin the first couple of rotations are quite normal and slow, but the next couple of rotations speed up noticeably before returning to normal speed. This is without any fresh stick inputs. Don't understand that one, but it's interesting to watch though!

The other observation is that while the Turnigy CA 120 motor does the job well it's a bit irritating that the prop shaft is only 30mm long and the thick hub on the prop only just fits on. However, I noticed that DualSky is now advertising the new GA8000 motor for 80-120cc aircraft. The prop shaft is 40mm which is much better and would also accommodate a 5" spinner too. Shame there is not any in the UK yet. I still think that she would probably benefit from a 14S set up too, but that would mean a new charger and 7S lipos ..... something I am not ready to do yet. Sticking to the 12S set up for the moment.

Thread: Futaba charging plug - tip positive or tip negative?
02/09/2020 15:18:00

Thanks, Denis. Appreciate it. I think I must have one of the more modern leads. Anyway thanks again. yes

02/09/2020 14:52:35

I know this probably an obvious question relating to the Futaba mains charger. Is the charging jack tip positive or tip negative, as I can't see how to establish this?

Thanks, as you can see one never stops learning? dont know

Well Dom I love 'em!

Most of it I will never attempt, but I ENJOY the clips. Keep up the good work.

+ one more for 10A blades thumbs up

Just a bit of feedback on performance et al after 11 flights. Firstly, the Turnigy CA 120 seems well up to the job and strangely appears to be quieter in the air than my DualSky 60cc equivalent motors. It may say more about the propellor size though, but I am not sure. I have been using a 28X10 prop although I am considering using a slightly bigger one as an experiment. I think the set up can bear it. Given the price of 'em I need to be sure in doing this.

The other observation is she flies very well in windy conditions and holds the line and is rock steady. While I am using Overlander 10000 mAh x 2 lipos in a 12S configuration I am sure using a 14S set up would improve things further. I would firstly have to buy a new charger as mine (UltraPower Quad) will only charge up to 6S lipos, although it will accommodate up to 10000 mAh lipos. And of course different lipos would need to be sourced. I am not ready for that type of outlay just yet as I am happy with how she behaves currently. Safe duration is around 6 minutes before calling landing which is enough for me, although I accept this will not satisfy the majority of flyers.

Neat, Peter. Funny how such a short clip masks hours of toil. yes

Congrats on the maiden, Ron. Looks good all round. See what you mean about the tail skid! laugh

Good to see some flying in wet weather, Bjarne! Jets are not my "thing" , nevertheless nice to see the flight envelope and a young lad showing his skills.

Right, all re-conditioned and ready for fitting out for electric or I/C.

Good for quite a while now as she is a decent sound airframe.

I knew you would sort it in the end, Peter. As for videos I upload the clip on to youtube first (reasonably quick if you have a decent upload speed) , then copy the youtube link into the MF thread URL box icon (car?) on the second row third from the left that shows up when you start a new post. There are other ways that it can be done, but it works for me. yes

Slow progress. Anyway I trimmed off the surplus GF and wet/dry sanded the spats.

p1060485.jpg

Now for non-I/C applications I really like to use Holts auto gloss colours as the finish looks really good. Therefore out came the red paint to spray the spats.

p1060487.jpg

Really pleased with the finish. Set aside to dry before adding some spare decals. Then I am ready to put her all back together and then decide what to do. I did think I might put some electric gear in her, but I already have one active 60cc Sbach 342 which is a Goldwing model. I know for a fact the SlipStream Sbach 342 is a great flyer and deserves some regular use. It is now ready to have I/C or electric applications added. I am debating putting her on ebay at some point as I am running out of "shop" space. It will be a wrench, but it may come to it. More pictures when I have finished the final details.

I feel your pain, Peter. I have had jobs in the past that have driven me up the wall. Even when I seemingly found a solution I was not happy with it again and went back to the drawing board. We are a tenacious lot we modellers and I am sure you will come up with something to solve it.

There are some small splits in the spats that need repairing. I am using my tried and tested method of fibre glass cloth.

p1060483.jpg

p1060484.jpg

Left aside to dry ready to rub down and spray paint. I am thinking of using the red that matches the film covering. I am also going to next remove the U/C and refit a G/F version and refit the wheels.

30/06/2020 17:35:17

Next on to work on the spats. I removed the decals ready for re-painting and a sticky residue was left on the surface.

p1060480.jpg

I recently bought a bottle of this stuff that cpmpletely cleans the mess off!

To the business end of the plane. I drilled out the original mounting holes to fit my dowel infills. and stuck with 30 minute epoxy.

p1060478.jpg

p1060479.jpg

That's it for this session. I will do some work on the U/C and spates next.

27/06/2020 15:22:46

Next recover the elevators where the studded horns were drilled.

same for the underside of the elevator. Repeated both sides.
