Default What sport/speed engine do you want to try next?

I keep a spreadsheet of every 40-52 sized engine (2 cy.) that I can find with specs. for each.... Price weight, HP (bogus but interesting) etc.

I have realized that there are a few engines that I just have to have sometime soon- I already have more engines than planes by quite a bit-

I currently have or have had:
Jett-50
YS-45
Rossi-45
Webra-50GT
Irvine-46/53
TT Pro-46
Magnum-46XL/XLS
K&B-48
OS-46FX (2)

But there are a few I really wanna try:
MVVS-49
Rossi-53
Novarossi-50
West-50
Enya-50CX
J'En-56 (close enough to 52 sized)
ST-45/51
Fox-46

What do y'all want to get ahold of engine-wise?

take care all,
james

In the size range of .40 to .50 I am going to do a project with a WEBRA .50 next. After that a speed plane for a K&B 6.5. I consider these to be trainer projects for what I consider a hot engine, but rarely mentioned here, and that is the NELSON .40. I'm waiting for my son to get me one someday.

Nelson engines are great, but really only usefull at full throttle or racing applications. They had a sport .50 out a few years ago, but at $400, I don't think they sold a lot and I believe it was discontinued.

The difference between a Jett and a Nelson are very small. I find the Nelsons easier to run, and a bit more consistent. Jetts are right there, but a little trickier to needle (IMO) with racing props.

For a Sport engine, I'd recommend the Sport Jetts all the way. You can get them to idle and transition, and your not really giving up much in terms of speed.

I love my Sport Jett .50 and Jett .90L for my speed planes, but when its time to race I use Nelsons exclusively (4 - .40 Q500 Engines, and 2 - .40 Q40 Engines).

Default RE: What sport/speed engine do you want to try next?

I want to try a JETT Fire 50 in my Diamond Dust. I am running a OS MAX .46 VF motor right now on it turning a 9 X 10 APC prop @ 16,700. The JETT 50 motor is supposed to be faster. I would try anything if it was faster and had a throttle control. Is there something faster than the JETT 50 out there I should try instead. I want to be able to throttle down though.

I have a set of blueprints and most of the parts made to build a Dyna Jet. [8D][sm=bananahead.gif]I'm stuck on the body tube though. I just don't feel like making all the tooling needed to spin it.
It won't matter what I put it in I will only get to fly it once after my club and their neigbors hear it.[>:][X(]

I watched a few guys practice FAI with the Profi .40 (Micklemeyer sp??) at the Nationals for a full week. Both the Micklemeyer brothers were there helping Lyle Larson and Fred Burgdorf set the motors, etc... After what I saw, the chances of me ever trying that event is slim to non-existent.

They blew a $5 glow plug on nearly every flight (8 out of 10, minimum).

Out of 10 flights, they were lucky to get 5 properly set needle settings.

After each flight (About 1 minute and 30 seconds) , they had to disconnect the muffler and take off the head.

On top of all this, I believe the motors are roughly $700.

It may be the fastest, hotest, FAI motor right now, but as high maintenance as you can get. I guess for people like Fred, and Lyle, who have won just about everything that can be won in racing. Winning a World Championship is probably about the last thing left.

Dave

I know there are some guys working with the Nelson FAI motor that have been having pretty good success compared to what I saw.

James, I am very relieved to see you put at least one MVVS on your list. Was that for me? BTW I got a line on the .49 with rear exhaust to put on my Patriot today. I also found an MVVS .28 [sm=bananahead.gif] to go on my Miss Los Angeles.
Yea, I am fond of them Czech motors.

Dave, you are right on all accounts...

But, like you've seen, when these things go, they really GO! High maintenance is something you have to live with in FAI.
Also, I don't know what props these guys were running, but I do know you can't treat an MB like a Nelson... Nelsons are "torquers"... and MB's are revvers...

And by the way, it's Metkemeijer... not Micklemeyer...

Thanks on the old school speed. Currently I get around 75mph slf with a .25 FX running an 8x6. I have a 7x7 to try next time out. It tachs at 16k with the 8x6, any ideas to get more with this motor or should I just grab that MVVS .28 and make some scarry noise?[>:]

RudeBoy,

Q40 is childs play in comparison in terms of maintenance, and the speed is not that much slower considering the smaller sized plane.

The FAI is impressive, but Q40 is tough to beat. The Metkemeijer brothers pitted right next to us, and flew Q40 at the US Nats this past July and really seemed to like it.

Randy....

sounds like fun.

However, the QM40 aircraft are designed and built for front intake, side exhaust engines. You may have a heck of time installing the rear rotor - rear exhaust setup. Let us know how that works out with the modifications. The 46 VR will be right at home with the regular APC 7.4" QM props.

The older F-1 and FAI planes would, however, be more suited for that engine...the F1 engines were RIRE.

Dave....
I definately agree with you on this one. QM40 is speed that incorporates absolute simplicity. Starting and setting the engine is not that much more difficult than on a Thunder Tiger .46 Start it, let it warm up a bit, turn the needle back to where it pretty much was the flight before, look for 22K on the tach....... and go fly.

I'm just about to get my feet wet in this game. I've got two projects waiting for me to build.

The first is a Shrike 10. I'm going to use a K&B 3.5 cc rear exhaust with tuned pipe. I've never run this engine in aero format, but if it works like my outboards, it should be good. Since this plane is small and simple, I hope to begin soon.

Next, while not particularly known for speed, is the K&B .61 Twister that I just ordered. At $80 I figured it was worth a try. Going to put it in the GP F-15 I just got off that "other" auction site.

The K&B Twister-61 is supposed to be light and powerful! The GP F-15 should be a great performer with the 61...

As an update I got a hold of an older Fox-50 that runs pretty well, and it has a built in aluminum spinner that is pretty cool-

The Novarossi still eludes me and the Rossi-53 is just soo expensive I would rather buy another SJ-50

MVVS-49 is toward the top of my list along with the Enya-50CX, and after I got my ST G-90 I want to try a ST-45 or 51 soon...

Take care folks!

I hope so, I've got to have something to let me keep up with "full throttle Fred". Not sure when I'll be able to start building, it's taken 4 months to get a little .15 size pattern plane to the point where I can begin covering it. Haven't decided whether to start the F-15, the Shrike 10, or something else next. Maybe I'll do the combat Gremlin and then the Shrike...

Number one on my wish list is a Jett BSE FIRE .50 with a custom full length tuned pipe. I think I would want the racing head so that I could run Nelson plugs and it would be set up for 15% nitro fuel. Then I would custom build a Patriot-like speed plane with a fiberglass fuse and pressure cowl.

Trouble is, every time I save up enough money for this kind of set up, I end up buying another BSE racing motor. Oh well, priorities. Right?

BTW, congrats to Dub for winning the NMPRA Championship race!
