I have had my YouTube channel for about 2 years now. I started it when I was searching YouTube for videos of engines I wanted to run, or was just curious about. After some searching I really did not find a single channel that had a consistent format and a wide variety of engine videos. So I started making my own. https://www.youtube.com/user/dmrcflyr2

They started out pretty crude but I think I have gotten better at it over time. Now I have over 370 videos on my channel. These range from nearly 100 instructional videos covering topics such as:

- Disassembly of a 2 and 4 stroke engines.
- How to set the timing on 4 stroke engines.
- How to replace the bearings on engines.
- How to adjust the valve lash on 4 stroke engines
- Tuning and setup of both 2 and 4 stroke engines

I also have a section on "Box to the Bench" reviews. this is where I run an engine straight as it came to me from a seller. Now I assess the engine externally first to ensure it is in running condition. Then afterward I usually tear it down for inspection and cleaning.

That leads to my "A Look Inside" videos. Here I disassemble the engine to inspect the components, and I attempt to guess the amount of run time an engine has on it based on internal condition. Sometimes I have quite surprising finding too. Most often it leads to a bearing replacement. Once this section is complete I make a first run after reassembly video or a Performance Run. these generally are the...Continue Reading

Seeing as I have several 50 size 4 stroke engines, 4 to be exact, how about putting a couple more head to head? My last 50 size comparison was when I ran the Magnum XL52RFS vs the OS FS-48 Surpass.

This time I will put my newest acquisition, an HP 49 VT, against a rebuild project engine a Saito FA-50. I just finished re-assembling the Saito 50 and up next for it will be a performance run. So why not add another video of the HP running with it? Both will be running Morgan's 5% Omega with castor added for a total lube content of 20%. Both will be turning APC 11x6 propellers.

Here are a few pictures of the contenders.

A friend of mine and an awesome member here, Balsaworkbench, was kind enough to send me 2 boxes of engines. Box 1 has arrived and box 2 will be here tomorrow.

Inside box #1 were a variety of engines but three in particular to be discussed here. They are an OS 10 FSR, an OS 10 FP, and an Enya 09 MK IV. I am excited about these engines as they will be the smallest engines I have ever run. I did A Look Inside the OS 10 FSR and the Enya 09(Just added link) to assess the condition of these engines. I did tear down the 10 FP also but I did not shoot a video of that.

With that said the engines are all cleaned up and ready to run. Fortunately Rob also sent three 7x4 propellers with these engines as I do not have props that size. This comparison will be done with these three engines running the 7x4 props. I have not decided which fuel I will be running but most likely it will be the Omega 5% with additional castor added.

Unfortunately this will not be taking place until next weekend as there is a low pressure system off the coast providing constant rain showers. This system is expected to hang around all week dropping tons of rain. So stay tuned for this next comparison.

Well it runs! Obviously I wasn't as prepared as I should have been. I really just wanted to see if it would pop over. Well it did, the first flip!

More to come.

I have added videos. They can be viewed in this playlist.

HP VT 49 The first run. (3 min 39 sec)

Well every since I have been in the hobby dating back to 1988, I have been intrigued by the HP VT 4 stroke engines but have never owned one.......UNTIL NOW! Can you tell I'm excited?

The ad did not show a box nor was one mentioned so I wasn't expecting one, but it came in one! Now I have had an HP .40 2 stroke Gold Cup engine before, but never one of these. HP usually uses the same artwork design on their boxes with just a sticker denoting what is inside. Now looking at the review from 1983 on the VT-21 I don't think this engine is that old. It is an Austrian made engine and I am not sure what year MECOA took over this engine line, but the exhaust does not look like the ones from the initial release of these engines.

I do plan on keeping this engine, it isn't going to cycle through my collection regardless of how it runs. I hope to get a video of it running very soon too. I need to look at and read the manual I found on the MECOA site or see if I can find an original manual.

Here are the pictures....Continue Reading

Well after some discussion with my subscriber that suggested this comparison, he has decided to narrow down the choices. This concluding segment features only the Saito and Magnum engines running 10x6 propellers and the FAI fuel. These were the choices due to the availability of these engines at his local hobby store.

I know, right? How cool is that? I haven't seen a 4 stroke engine IN STOCK on the SHELF in my LHS in several years. Well his shop must be pretty cool.

I tried doing these runs Tuesday night but had nothing but problems. Neither engine wanted to run for crap, they were getting hot very fast resulting in very erratic WOT RPM. The idle needle on the Magnum on this engine is so loose that it vibrated closed resulting in the engine dying at 1/4 throttle. I had to remove it and wrap it with teflon tape to add some friction.

Then my electric starter cone kept coming loose. Basically nothing was going right. Tonight, however, was a different story. I ran both engines and they ran great. Check it out.
