  1. I have used PVC pipe cement - obtainable from hardware stores - made by Marley from memory. It dilutes with MEK just like the fabric cement and works well. I'm no chemist, but it seems to have the same properties. No doubt the purists would frown on it, but for a patch I'm sure it would be ok.
  2. Yes - they are pretty user-friendly - Phil Perry is right - the accidents which have occurred have happened because the pilot got too slow turning on to final. The later wing is much-improved from the earlier options. However they do take some time to build - most part-timers would take at least a year.
  3. I have an Alpi 200 Pioneer at present - lovely aircraft, but the rough strips I tend to use have given the U/C a hammering and its just not handling them. I'm looking at doing a Nynja kit sometime soon - it was a choice between the Nynja and the Savannah, but the shorter build time of the Nynja clinched it and I have previously built the early model which went together very well. Looks to me from the website that the kit is now much more complete. I am hoping that there is an option to cover the control surfaces in ceconite rather than dacron - is this possible? As far as performance goes - ca
  4. I had a Skyranger with the Simonini Victor 2 (rated at 92 hp). Based on my experience with the engine I would not buy one again, Yes - the claimed hp figures are dubious at best, the claimed fuel consumption figures are a joke ( I normally used 15-17 l/hr at slow cruise). the gearbox had several faults which we discovered before any real damage was done, the heads had not been properly torqued, causing a blown head, vibration was a major issue ( somewhat improved by fitting a 3-blade prop), noise was also an issue - even with an ANR headset. Oh, and because it had to be installed upside-down,
  5. Not only has the site been down at regular intervals but it seems they aren't interested when you tell them they have scam ads on the site. There is obviously no scrutiny carried out.
  6. I used all VDO when I built the Alpi - good quality and reliable ( and cheap)! Easy enough to mark the gauges with coloured strips
  7. You are kidding right?
  8. We have noticed a similar trend in NZ, with an ageing recreational pilot population, but at least the recreational scene is growing - both the major Part 149 organisations (RAANZ & SAC) have growing memberships. Our club has 240 members, up from 150 3 years ago, and the major factor has been the acquisition of a couple of Tecnam P92 Echoes, coupled with the very sensible level of regulation for microlights (ultralights). We strive to keep regulations at a minimum for safe flying, and the costs at a reasonable level, and the result has been a massive migration of general aviation pilots ac
  9. Here in NZ we have seen a couple of Sierras modified by moving the main gear forward, and also beefing up the nosewheel. These mods transformed the aircraft and it becomes much easier to land. The basic problem is too much weight on the nose making it very difficult to flare.
  10. Definitely not right - I just completed a HiMax (same wing) - as I recall there was approx 1 1/2 deg of washout required in terms of the plans. HITC probably has the right idea - either shorten the front struts, or lengthen the rear struts (as I recall the rear strut is sleeved at the wing attach point to allow for adjustment) and you should be able to get enough movement to produce washout at the tips. Sorry IBob, but its nothing to do with dihedral and anhedral !
  11. Welcome aboard - interested that you found the handling qualities of the Foxbat & Sling to be good but not the Savannah? I am planning to build a Savannah at some stage, and they are very popular, both on Oz & NZ. Any comments you might care to make?
  12. I see the VW engine has a belt reduction fitted, allowing it to have a bigger prop than would be normal for a VW - thats why the climb rate is so good. Nieuports are noted for being a bit squirrelly on the ground due to the quite small rudder, but this one appears to be very stable. Good job!
