Thanks Alan . I am really looking for a combined control system and ideally not two seperate controls .As with the speedster, I dont want to have to release brakes to fully utilize tip steering especially while low and on and off speedbar, it looks like Dudek are working on it calling it Integrated Control but its seemes it is still not ready for release...

I am flying a speedster and would love to be able to combine brakes , wing tip steering and speedbar in to something more intuative especialy when flying and turning low . the best looking system i have seen is http://www.scoutparamotor.com/advanced- ... slav-svec/ Question is.... has anyone tried this as a retro fit or any thoughts on how it might work on a speedster or any alternative ideas out there ?

Excellent photography there Steve! thanks Stevie, a friend of mine Mick Petts made it and he only recently got to see it from the air in person courtesy of the One Show in a hot air balloon ...got to be the best viewpoint !! he was also commisioned to make the mother earth figure at the ebbw vale garden festival and a wild boar near Fochrew

agree, a fabulous piece ! I got some nice images a few years ago http://www.stevebrockett.com/Galleries/ ... /i-Mbs5pjS

A couple of years ago now but these were my first attempts at video, for those interested , filmed with a go pro on a foot mount with a 12v monitor on my instrument pod , this worked well using the cover of the instrument container as a sun shield and the foot mount giving great control ( used a quick release mount on my boot so I could take off and land without damaging the lens ) used Mercali a post stabilizing prog hence the jelly wooble but with carefull editing tried to reduce that to a min . would love to do some more especially with more efective stabilization but have been concentrating on aerial photography rather than film . http://youtu.be/_6gORstJ554 http://youtu.be/bPqfO7dz5-4

Think you were right Pete!, put new metering spring in and seemes to have cured that

Yes good point and have redone both gaskets and retorqued after every flight ..the amount of attention this motor is receiving at the moment ! girlfriends complaining a bit!!

Thanks for the ideas gorden , but the filter is new and very clean ! and the impuse tube new as well !

thanks alot for the offer that would be great just have to work out when i could get over could you PM me a contact number? thanks steve

maintain around 6100 revs on a PA125 for aprox 10 -20 sec and then it surges up to 7200 without any increase in throttle pressure ...any ideas anyone ? it will also drop revs when cruising for a few min at around those values

an update ! after repeated attempts to clean the carb, I still couldnt get a reliable idle., followed a suggestion from Rowena carbs I bought a Maplin ultrasonic cleaner..I was a bit skeptical I thought it was last thing to try before ditching, but what a difference http://www.maplin.co.uk/ultra-7000-ultr ... ner-223108 I cleaned twice both sides (tray not quite deep enough to imerse all of carb)on 8 min using the cleaning fluid and got the idle back! I got rid of the primer pump but found couldnt start the motor well ! probably needed more practice or puff! so re -installed that still running a bit lean, so that was sorted by bending metering lever up to 0.75 below carb body as it had been set using the walbro guage at 1.7mm first time in a long time the motor sounds right and plug nice colour

Thanks notch ...thats this evenings activity then ! cheers

thanks for all the ideas and links ! really useful My carb has a 3.2 mm inlet . I have fitted the carb kit and now great! no air bubbles , leak solved ! However the bloody thing still wont idle ... so leaning back towards dirty idle Jets... anyone tried sonic cleaning ...as my attempts with carb cleaner havent worked me thinks

Thanks for the ideas! will try the priming with blowing technique! hopefully new membranes and new needle valve will sort but will give another clean , Id used a tube with angle cut in end to blow carb cleaner in small holes , but really fiddly ! beginning to regret advice from PAP to remove internal filter!! believe that started with the Ross 125 and they recommended for PA125 as well

Thanks Notch. yes suspected that join, and I replaced that bit of pipe and double wrapped cable tie all to no effect , more and more suspecting the needle valve , but should get the membranes and kit tommorow so will see ! When cleaning Jets in the carb there seemes to be 5 holes in the chamber , near the butterfly anyone know which are responsible for the idle or are all of them ?

Trying to get to the bottom of No Idle on ...PA125 fitted with the WG8 carb, after priming engine the top fuel filter is full apart from a regulation small bubble after 3 sec a stream of bubbles is seen to come from the carb side . Im assuming this is something to do with the 'no idle' situation and running slightly lean!. I have changed fuel lines , primer bulb and all that seemes airtight . I have stripped and cleaned carb twice , Have ordered new membranes and will check meter level but seemes ok , but while waiting for them to arrive does any other causes spring to mind?. missing this nice weather is painful!!

I joined the Gaer park model club in return for using their field , in between Cardiff and Newport fantastic take off for all wind directions. send a PM if you want more details

Hi Simon do you have a contact number for the guy how does the repairs thanks

Thanks for the info Notch I did change the base gasket. I made another out of 0.6 paper and with a bit of gasket sealer put it on top of the other one now the squish is slightly over recommend 1.5 /1-6 but will probably bed down a bit , But at last it works!!! also reset the magneto gap it was a little off but not that bad Put a sleeve and brass washer in starter this reduced the play (but not sure this had much effect) anyway something did the trick! forgotten how sweet it all sounds Really didnt fancy drilling out cylinder !

In Case anyone else has come across this problem and it is found not to be the timing . I talked to Pierre from PAP he suggested two things the Gap between the coil and flywheel should be 0.6 not as it says in the pdf 0.4 Also suggests it could be wear on the starter mechanism , which locks up when a lot of tension is applied. mine certainly shows alot of lateral movement! and its interesting that this was noticed in previous post I have now noticed that the pull start mechanism is now looking a little worse for ware from all the excessive pull due to the hard compression. and it sort of maybe ties in with the generator fix thanks for the ideas will try tommorrow!

I have adjusted the Squish with a thicker gasket but still the same problem ! Can someone tell me if the timing is out , would I not notice a difference between the sparkplug lead on or off ? if there is no spark then there is no advance? or could timing still be the cause. if not then any other ideas please ?

Hi Dara Im having the same problem with a PA125. although it does have a clean decompression hole ! .was it the timing?did you ever get to the bottom of this?

Thanks clive ...yes I guess it has 30 to 40 hrs after a brand new carb was fitted ,the membranes dont look brilliant so will change them , however even with no fuel , no priming ,etc its still very hard to pull over, which was leading me to think along other lines ! off to buy some solder to measure squish, and will be interesting to see if thats spot on a bit of update... squish measured and its reading 1.04 -1.20 recommended 1.3 - 1.5 so off to get some gasket paper tommorow see if that makes difference

Thanks for the link notch, will give it a go!

Hoping someone has some news as to why this would happen! My pa125 has exactly the same problem as described above just taken the head off ,cleaned piston checked ring, cleaned decompressor hole (wasnt blocked) then broke the starter cord trying a start (obviously not fixed then ! ) any Ideas other than Timing? no fuel in motor so not a vapour lock
