Hello to all. I see there has been no posting for a month. As a new guy, would anyone care to update me on the HCI engines as to how many are out there, how...
You can pretty well glean that from reading through all the previous postings... It's a heck of great engine, but it's all about marketing, isn't it? Andy and...
First, what a cool group you guys have here. I've already learned more here than I have after many hours of googling. The HCI radial is very interesting. I...
... Hi Rob, I won't comment on your first question beyond saying that Jack has many hours on his engine and the rods weren't a problem. The answer to you...
Thanks Phil Rob: First question: Most radials have successfully used aluminum rods. The thought of using steel never crossed my mind, but your thinking is...
... Jack, Good too hear from you. The Morgan, it turns out, builds at the same rate as a radial. Half done and 80% to go. Ironically it is the balance issue...
Thanks to everyone for all the input. Thanks to Doug for the nice solution to the geometry problem. Concerning aluminum rods: Is it really true that most...
Lycoming, Continental, and Franklin also use aluminum push rods on their horizontally-opposed engines. The ends have polished steel ball- type inserts though,...
Hello All - VW beetles also get away with aluminium pushrods as described. Back in the late 60's when I was dabbling in rallying I shortened a set of them for...
Thanks Chris. Yup, that was the question. Are aluminum connecting rods reliable? I still have not found a definitive answer. However I have looked at some...
Hi Rob - back in the 60's Triumph twin motorcycles used light alloy rods - revved to 6500 with no problems. Always felt disgustingly light in hand - but never...
Thanks Edi, I'll look into the Triumph rods. I guess I better get off my butt and pick up some serious books on engine design. My experience has been...
Hi Rob - why don't you spend a couple of years flying sailplanes - stay with it until you have done a few X-country flights - just in case :-) Every landing a...
Wow! I thought powered airplanes were exciting! It probably would be a good idea to get some practice with off airport landings. I've been talking to some...
Hi Rob - did I mention that sailplanes have no engines? No deathly coughs and unexpected silences. No expensive parts to buy and fit. Clean hands maintenance. ...
More off-topic - Edi, you might want to have the CFI modify his trick to approach the slopes at 45 deg in case the ridge lift changes or rotor develops by the...
Hi Chris - that all happened some 20 years ago. Our instructors are all pretty experienced - the approach would have been made at something like 30 degrees to...
P&W and most other production radials don't even use shims, they just let each cylinder run where it runs based on the master and link rods. They do however...
Where are you located, Edi? Chris ... like 30 ... hasn't gone ... to make ... away ... fly into ... trying ... last minute ... Antonov 2 and ... cargo ... ...
Does everyone know about the Aircraft Engine Historical Society website? It has tons of info on airplane engines. There are loads of pictures and lots of...
Are there any suitable for ultralight use radial engines available? I'm not a machinist, so perhaps I'm in an inapproiate for me group...? I'd love to have...
... available? I'm ... group...? I'd ... What ... Jack was tinkering with the idea of a three cylinder radial a few years ago. Don't know how it went. From...
