hmmmmm....   looks significantly slower than my Magnum......

Ha.!

Is you twin outlaw coming out to play again this year?

Tell me more about this plane.

evan-RCU

I don't know....

Idid fly the Magnum a few weeks ago though, it's a easy plane to fly, almost as easy as my electrics. That Weston .50 is one fantastic motor...

Alot of speed freaks love this model for its simplicity to get you fast with the recomended set up. I'm sure someone can guide you to a distrubitor in you area.

The above uk link I've given you might be of interest

Was that you in the 200 mph vid?

I've always doubted the 200 claim. Mine only ever got 160.

Evan the twin dust would be exciting at the rally this year.

So far not one person flying a West equipped Magnum has ever reported anything higher than the typical 160-165 number we hear, perhaps the occasional 175. At least not anyone who has accurately measured the speed. With the exception of Weston UK who claim they not only regularly fly 200 mph but that their factory models have flown over 240. I wonder who volunteered to point the radar gun straight up at a Magnum in a WOT terminal dive?

Shame I stripped mine, would have been curious to clock it at the rally. Chances are there might be one there I guess.

You know there will be[8D].

The guys are looking forward to seeing you down here. I'm starting on this year's entry.

evan-RCU

MJD what are you bringing? One of your new buisness's products? Be nice to see. What do you mean stripped your magnum? Stripped the gear out for another project?

Had fun today Vic, thanks again.

Nothing like being ahead of the game..

My glass wonder model might be bumped by a .65 delta, given that it would be somewhat of a prototype. And easier to finish in three weeks.

I'm looking forward to the road trip and tomfoolery myself! Spent too many years at rocket shindigs, time to hang out with airplane geeks again. Better check my passport is good..

Your MAAC is good to go too per the email I got the other day.

I've always had trouble clocking my Magnum with Weston 50 motor in it. Difficult to fly it close and steady enough for the damn gun to lock on. I got reading of 137mph couple times but think it's a little faster than that. I bet anyone saying 200mph is only guessing at the speed. I'd like to see a youtube clocking of a fly-by before I will believe the 200mph quote.

My Feedback: (1)

The folks that have clocked them report speeds in the 160-165 regime. Never clocked mine. 200 in a dive maybe, not that it has been substantiated. They are quick though, no doubt about it. Fast, but not 200 with a .50.

You gota go 8x10 to go real quick.,if you can launch it that is!!!

I spoke to weston about swan necking the the header and putting the pipe inside for less drag.. I THINK i saw someone had used a rear exhaust engine and do the same idea.

160 180 200 All is quick.!!!

They are testing the mini magnum now, with their hot 36v1 set up

I spoke with Alan at Weston UK last week concerning my West 50 that I returned due to a bad plating job in the liner. They fixed my engine no charge.

We spoke at length about tuning the engine as well as some of the projects that he is working on. One project I had seen on their website, which is no longer on the site is a pair of West .36's ganged to a gear drive (1:1) to turn a single prop. He said that this pair of engines made almost 6hp. I asked him what plane that it might be designed for, he told me that he modified the front of a MagnumR to accommodate this engine(s). I'm suspecting that the claim made of over 200 mph was probably with this engine in it rather than the .50 Notice on the site that the 200 mph claim does not refer to a particular engine, though it's inferred that it's the 50.

mk1spitfire

The claim was made before the twin engine prototype.
Though the claim could also be interpreted as ground speed.!!

I must get around to tryingto putanairspeed monitor on it.Even a no wind day the air and ground speed will be the same. The vertical dive is another variable and of course your style of flying.
Fly itVERY high and vertically drop it pullingup GRADUALLY as not to loose speed near the ground for a 50meter passthen up to feel its speed, Even better downwind.

I've got a shim to try and will up the nitro

"The claim" may also be based on a nanograpph. RPM vs pitch= speed, Maybe 8x10 pitch??

What puzzles me is why it was never spec'ed as RE in the first place.. a golden opportunity missed in my opinion, it's already a special purpose engine after all. It's a great engine, and the best part of the package by far. It hauls my delta with serious attitude. Midrange is a bit wobbly so far on the open pipe, needs fiddling.

I flew an 8x10 too, and it was quick, but the delta still smokes it from what I can tell and I doubt it is close to 200, I'm guessing 170's but I hope to find out fer sure in NC. A while back someone did an article everal years back in RCM&E I think, about putting an MVVS RE engine in a Magnum and burying the pipe. As I recall the article ended with him having continuing trouble with the engine and the numbers didn't look too exciting. I originally bought two Magnum R's with that idea as well for number #2, but I lost interest after flying the first one. It's fast and all that, but I never fell in love with it's flight characteristics. #1 is in limbo, I dinged the LE, and if I was motivated could have it completely repaired in about 45 minutes I figure. But when I stripped the wing and saw how bowed and twisted it really was I put it away for now. I might pull it out later, refit and thrash it.

I have not built my Magnum yet. Was breaking in the engine on the Kaos, found a problem with the plating and sent it back. I now have the engine back, so it's time to start the Magnum build. Probably start with a 9 x 7 for maiden. Will likely break the engine in again on the Kaos.

Too many projects, not enough time...

mk1spitfire

great prop choice for all round flying with easy lauch, vertical infact..!

time flies by.....especially at the field

BiggerDanno

Made from a Webra crankcase. Would require a significant change to the mold. Which would likely drive the price way up. I'm thinking it was just an attempt to see how much a Webra 50 could be tweaked.

mk1spitfire

Is there a webra RE that could be tweaked?

I've looking at a rossi 50, great horpower without the tuned pipe yet on it

MJD

My Feedback: (1)

I guess I figured Webra must have a RE block they could have used, but could be wrong. It's a great engine for light deltas too, as I found out recently.. ;-)
