I still haven't managed to start it except for a brief 30 second run at rick over. I have just stripped the carb down again thus afternoon and blasted carb cleaner to make sure none of the jets are blocked. Apart from that, it is finished. If I can't get it started I'll try and get an AGM30. However, they seem to be as rare as gens teeth at the moment. I'll also try swapping the plug although I do seem to have lots of sparks when I spin the motor using my electric starter. Whether the dark are at the right time is a matter of conjecture.

Hi Pete

I would love to see a return if the BoM rule for classes like 100S which were always intended to be introductory classes. However, I think the bird has flown in this case. Introducing such a rule, if you could get support, would simply kill the class completely. It will die a natural death as Trackers become unobtanium at which point, some common sense may prevail. Be interesting to see if anyone actually cares enough by then to something about it.

There are many who would say that assembling a model like a Tracker is building a modrl. The only way out of that would be to implement technology restrictions like F3-RES to level the playing field. You have to bear in mind that foam cored wings are illegal in F3-RES. Early 100S models were mainly foam cored.

Well, it has flown. Nice day but a bit blustery and a 45degree cross wind. But it flew quite nicely. Picked its tail up a bit sooner than expected on take off and it was a bit too soon do was a bit sluggish and risk if a tip stall for a few seconds but once up to speed it was lovely. Stooging around on half throttle, a bit too sensitive on elevator and needed more aileron throw but very gltable. A couple of rolls in both directions and a loop that was far too tight confirmed my suspicions about the throws but apart from that it was OK until I tried to land. Heck, it doesn't half float on and with a strong cross wind and little headwind, it took an age to get the descent right but eventually I got it down in one piece.

A few little jobs to do but feeling quite chuffed. Only took 4 years and 17 days. Many thanks to Danny, couldn't have done this without you. dsc_1214.jpg

+1 for the KK Senator. The only tricky bit is the 1/16 square wing spars which are adequately strong but need careful handling.

Your build quality is amazing Martin

I was thinking of going down the yellow path as well. However, I am not sure what colour of Yellow it is.

There doesn't appear to be any gun troughs but they may be not visible from this angle

checking CH1 and setting the switch ON when the CH1 value was > -95 say.

Should that be < -95?

Hi Geoff

This is on my wish list so watching with interest. Have you compared the outline with a 3v to test its accuracy? I think it would make a great candidate for the new BMFA Light Scale class

Thanks Danny

Its not quite finished yet, scale-wise, but it is ready to fly. Just waiting for a Rx battery.

Hi Colin

That's looking very nice.

Did you use brass bushes to protect the hinges from abrasive wear? I used 10ba bolts in brass ferrules on mine

Thanks Colin

Deffo not Danny's standard but quite pleased with it

Still a few jobs to do. Fit a rx battery and switch and make a better cowl lick for the lower cowl. Canopy is only held in place temporarily coz there are a few more jobs to do inside.

Wheels and spinner are obviously wrong as well but it's almost ready for a maiden. Weight. 3.7kg .

Not much more to come.

I would follow the plan. I find that spoilers can blank the tailplane too much and cause big pitch down movements

01/10/2019 10:16:39

Thanks. That a very good slippery low drag wing section derived from a Pylon Racing wing section I think. It should be OK in a breeze as well providing you keep it moving.

3.5m span as well. A nice size

Hi Brend

The wing profile.. It looks like a Clark Y but difficult to be certain.

I wish our club did that. We used to have a monthly 'meeting of minds' in the pub but that was very informal. Which club are you a member of?
