    Carb Ice protection with electric heaters?

    Original builder trusted in heat conduction up the short intake manifolds to prevent Carb Ice. The plane has flown a good bit and I expect he would have changed it if it needed it. Sadly he has passed and the set up worries me. Thought I could add these 20W heating pads. They have a...

    Light weight diesel auto conversion

    Though the engine is taller than the traditional boxer, the only flyeco installations I've seen are vertical.

    Light weight diesel auto conversion

    Actually, the numbers on the smart diesel / flyeco conversion are pretty well documented. 80hp at 196lb complete installed weight. This compares well with the Rotax 912uls (100hp) installed weight of 194lbs. though the diesel delivers 20hp less at sea level, the diesel installed weight...

    Light weight diesel auto conversion

    yes - this engine is quite similar to the mercedes smart diesel (maybe the same?). same 800cc. same 3 cylinders. same weight. the smart car engine I'm looking at has already been largely aircraft converted.

    Light weight diesel auto conversion

    I'm very interested in making this engine work for my KR2s. https://inlandempire.craigslist.org/avo/d/riverside-brand-new-turbo-diesel-81-hp/7489893350.html Scot is asking $5K each and has 34 of them. They are almost bare engines (as pictured) and will need wiring and plumbing - so not a small...

    SDS Ignition

    Hi kr2pilot, Sorry for the delayed reply - I dont check this forum regularly. If your ignition is working well, resist that urge to jigger it up with bright shinny improvements. Fly! That said, the SDS system has a very good reputation in the homebuilding community even though it was...

    AeroVee 100 HPTurbo

    Back to the original question of this thread - aerovee turbo? Turbocharging or turbo normalizing - how could anything make more sense for aircraft that by definition operate at widely varying air densities (altitudes). I used to fly a turbocharged Bonanza - a plane that had gotten a bad...

    2180 heads

    Every cooling trick? My priority would (does) look something like this: Good airtight baffling and the inter-cylinder tins are essential and #1 priority. Cowl flaps or good "lipped" air exit (with ~45deg lip) 8.5:1 or lower compression Clean oil passages and removed oil restrictor to...

    Nikasil Cylinders

    Hi Guys, Just to remind - not all Nikasil coated cylinders are the same. They basically fall into two categories: 1) cast (cheap), and 2) forged/CNC'ed (expensive). Generally, the cheap cast cyclinders are made by QSC and have been resold by Sonex before even they decided QSC was trouble...

    Is wearing a personal chute with a bail-out system acceptably safe compared to an airframe chute?

    I bought and wore a personal chute during Phase I testing of my Osprey. But now the probable complications of actually being able to bail out of a pusher in a quickly progressing emergency has left me rarely wearing it. An airframe chute would be way better for me in the Osprey. However, in...

    Nikasil Cylinders

    Hi slociviccoupe, Sorry for the cast/billett disagreement. I hadn't read too much about Nickies, just talked with the company, with Scott, and I've held them in hand. And this thread started with the question "Does anybody know of a successful combination using the cast aluminum nikasil...

    Nikasil Cylinders

    I think you are wrong. Both Scott's and LN engineering say their cylinders are CNC from billet. I've seen both and held both in hand - they look very very different from a cast cylinder (such as QSC's). From VW Type 1 - Nickies Cylinders for Aircooled Porsche and VW Engines - Products "Our...

    Nikasil Cylinders

    Nickies are fabulous and truly "fix" the VW... well maybe. Much as we love the VW - a 1930's engine designed for 37hp and now composed of a hodgepodge of aftermarket parts with no unified QC, specs, or tolerances - all pushed to continuously produce ~60hp, is not a receipt for reliability...

    Ferry Permit during Phase I Testing?

    Thanks for the feedback all. Quite the variety of experience and advice! I'm planning on putting together a 5-10 hour local flight test followed by either an amended narrow/long test area or a ferry permit to a new area - and will stay completely open to "my plans" being changed by reality...

    Ferry Permit during Phase I Testing?

    Hi All, I am looking into buying a newly completed project. Does anyone have experience with getting a ferry permit during Phase I testing? The airplane has not yet been inspected for airworthiness - but that could be done as soon as I can arrange it. The build is great, but I expect a...

    Light weight diesel auto conversion

    The DV6 looks really promising (Thanks Sming and Geraldc). I was also checking out the Honda N (cheapracer). These are both right in the power/weight range I was looking for. Any others?

    Geraldc - Thanks for the pointer the the DV6! Thanks exactly what I'm looking for. Cheers!
