I started gliding with the air cadets in early 70's went onto become a staff cadet at two VGS's then did an RAF flying scholarship to get my PPL. Flew with the RAF GSA at Bicester for a while before finding that time and money prohibited doing both so I reluctantly quit gliding in favour of power ma...

In the last year of flying my Veep 1 I made a tuned length 4 into 1 with mandrel bends and a short tail pipe . This transformed the sound from the familiar, and loud, POP POP POP to a deeper throaty burble. I didnt test it enough to see if there was any real performance benefit by way of climb and f...

No you are not alone! If your CofA does not permit the use of the soft start module then there is still a few things you could do. Firstly fit the HD starter, and change your battery, if yours is still the original one[preferably for a new Odyssey battery, if your CofA conditions allow]. If you have...

have a feeling that for the SR4 magnetos you should use 1000 Ohm resistor caps. Brain fade is preventing me from finding out any references and the caps on my Veep 1834 engine are not marked as far as I can see

[/ Well the RV10 wipes the floor with most PA28s (the 140/150/160 etc versions) in both performance and capacity, the RV being a true 4 seater rather than the 2+2 capacity of a lot of PA28s, and 172s come to that .] That maybe, but the RV10 uses 250 Hp to do it, look what Piper managed on 250hp back...

Hi BJ I have been over your strip a few times nov/dec but you were not about. We have put up some new hangars increasing our capacity by some 9 permit/microlight hangar spaces and I am moving out of my present hangar into one of the new ones. So this would be an opportune time to sort something out ...

And of course herein lays the answer, a third organization apolitical and with no hidden agendas with regards the certification and approvals process. Neither LAA nor BMAA can truly campaign for across the board [permit aircraft] recreational flyers interests when both associations are in essence re...

A fuel pressure guage is a useful addition to the panel to keep an eye on this sort of stuff. Skydrive sell the Rotax guage which has the guage face painted with the correct pressure limits, bit pricy though :o .

Mike The UK S10's are generally fitted with the 582 or 532 engines, as far as I am aware none have a 503, a couple have the 912. Performance with the 582 when solo is good and I flew mine comfortably of the 350yd part of my 500yd strip, 2 up needs a bit more of a take off run but still adequately co...

Pete Steve has summed it up so I have not much to add, but bear in mind that on the 912 and Jabiru the inlet manifold is very short and on the 912 is an aluminium casting, so a good conductor of the cylinder head heat. On the Bing the elect heaters heat the throttle shaft/butterfly, keeping it ice f...

Ben, are you sure its carb ice? The 912 is quite resilient to carb ice depending on how the installation is configured. For example in the RANS S6 the coolant radiator is above the rear of the engine and the carbs sit in the warm downdraft. Never say never ! but i never had carb ice in the S6. If yo...

I find all this rather sad really its a poor reflection on Jon Viner that some feel he or the orginisation he chooses to join should be chastised in some way from furthering joint interests and careers. After all not much was said, as I recal, when the previous incumbent left the post for Jon to fil...

'Any Super2 will benefit from extra elevator authority in the flare; but aileron response is good enough already.' Mention this to Joa Harrison as fitting VG's to the wing might aggrivate the elevator issue? the solution of course is to fit VG's to the tailplane too.. If buying some you might try f...
