Does anyone have experience with these engines ?? I bought a .32 for a future scale project from Nitro Planes at 44.00 they show all different sizes (most out of stock) but they had a .36 and was just wondering if it was any good ?? They have a lot of sizes Thunder Tiger and Magnum use to carry at Cheap prices..They are China made. Any comments welcome !!

Hi, Leester.
A while back, I acquired an Asp 32. With a very slight modification, it turned out to be a very good stunt engine.
It was given to me without a venturi or carb and I assume it was an RC version.
I had it on a Sig Banshee and with an 11-4 Top Flite, it did a very good fast and steady four cycle run.

The ASP S36A is apparently the same engine as the Magnum 36 that was popular a few years ago, just with a different name on the case.

I heard that,too. The Magnum 32 and 36 are stellar-running engines. The 36 runs a lot like a 90% version of a 40VF and is much, much smaller. It's almost comical looking at then side-by-side. The inestimable PTG ran them with muffler and pipe with very good results.

When they were still being sold as Magnums, if you went to the Hobby People website, one of the "popular accessories" suggestions was a 5-pack of head gaskets - proving again that bad ideas were just as popular in 1995 as they are now.

There is a 36a and a 36a2 does anyone know which would be better in the 36 size Hobby Partz has them both for 47.00 sounds like a deal if they will do.

Leester · « **Reply #5 on:** January 08, 2015, 07:43:20 AM »

Thanks for the reply's. Hobby Partz www.hobbypartz.com has the ASP S36A & S36AII both for 47.00 ea. There shipping is over 50.00 free domestic, to ship the engine only ( under 50.00) was there standard shipping fee which was 6.95 I'm guessing the difference between the two is the mfg year. I bought the S36AII total shipped was 53.95 each engine weighted in at 322gms Others have the ASP line but want 15.00 + for shipping

You try the 36a2 yet?

Leester · « **Reply #7 on:** January 08, 2015, 08:31:02 AM »

Just ordered it. But I did have a Magnum 36 in an ARF Nobler with a Venturi and NVA from Randy at Aero Products and it was fine. No 4-2-4 run just a steady run.

Do you know the id on the venturi

Leester · « **Reply #9 on:** January 08, 2015, 11:15:23 AM »

Nope, I don't have it any more. I'm sure you could find out the best size from Randy.

Hmm, wonder where it went...

Somewhere around .260 is about right for the Magnum .36, should work with the ASP too. I measured the venturi in the Magnum I got from Lee, but don't recall the exact measurement. I've never gotten around to running it, as it's the spare for the Magnum 36 in my Vector. I run mine with a .260 or .265 venturi, Randy NVA, normal side exhaust MACS header and pipe. It runs great with no audible break, just dead steady consistent. The ASP on hobby partz is very tempting, but I've already got too many other engines. If you order two the order qualifies for free shipping.

The 36A is the spitting image of the Magnum, minus the logos, the 36AII appears to have a different case. Who knows what else may be different internally.

I have a Magnum 36XLS and it is happy with a .270 venture [using a .155"dia. NVA]. I started with a .260" but it was too small. The ASP's are Magnum copies so I would think the same size venturi would work in the ASP also..

...The .36A and .36AII have different heads. Cheers. John

Would the 36a be a good match for a twister looked around may not be searching for the right thing

big ron · « **Reply #14 on:** January 08, 2015, 04:57:05 PM »

Found it searched magnums 36

Leester · « **Reply #15 on:** January 08, 2015, 05:01:23 PM »

It will fly the Twister with no problem but the 36 will be heavier (weight shown as 322gms) and you'll have to balance with added weight to the tail. The OS LAS 46 is 246gms (I believe without muffler) so....your choice.

big ron · « **Reply #16 on:** January 08, 2015, 05:06:33 PM »

Gotcha

Andrew Hathaway · « **Reply #17 on:** January 08, 2015, 05:56:39 PM »

My Harbor Freight digital scale puts the LA40 with plastic backplate, RC carb, no needle, no muffler, at 253 grams. I weighed my spare Magnum 36, as I received it from Leester two years ago, with aluminum venturi, PA NVA, no muffler or extras, it came out at 239 grams. I'd expect the LA 46 to be marginally lighter due to the thinner lighter/larger piston, but I would argue there is probably not a more powerful engine in a smaller package than the Magnum 36. It's the same bolt pattern as the OS 25F, and roughly the same size, the OS 32F is actually bigger with it's added cooling fins and taller head. I'd say the quality of the Magnum and probably the ASP is considerably better than the LA46, and while it probably won't run the same, I couldn't get my LA's to run consistently while the OS 25FSR, 25F, 32F, and Magnum 36 all run very consistently. If anything I'd expect the Mag 36 to be borderline too much power for a Twister.

Probably been discussed before, but asp are not Magnum copies, but rather the same engine from the same company. Sanye engines produces asp, magnum, SY and SC engines. I believe a few others, but mostly branded as these. If you contact them, you could have a run of engines with your own name as the brand.

Leester · « **Reply #19 on:** January 09, 2015, 05:44:09 AM »

Andrew, The ASP is the 36 that weights 322gms by the web site specs which I'm sure is with carb and without muffler, The LA 46 is lighter than the 40. The 246gms is from Towers specs. The Mag 36 would have more power than the Twister needs but better more than not enough.

Just checked the weight of the ASP 32 I just got and with carb it was 280gms and this is listed at 325 on the specs. The muffler weights 65gms.
When I get the 36 next week I'll get some actual weights. Hey Andrew if not to much trouble what is the outside measurement of the venture that fits into the carb mount?? Thanks

Andrew Hathaway · « **Reply #20 on:** January 09, 2015, 11:50:12 AM »

I'm pretty sure it's about 13mm, a hair over 1/2". When I switched to the Magnum 36 I robbed the venturi out of my OS 32F, the 32F RC carb in my junk drawer measures 13mm OD.

ASP = Magnum. We seldom see ASP's in the USA. Hobby People, who has the Magnum name brand, stopped importing the XLS .36 for some reason...probably R/C guys didn't like the .36 when a .40 was about the same price. They don't care much about weight or size, just how fast it'll turn a 10-6 and how well it idles. I don't understand why they have a .25, .28 and .32. Seems like too many to me.

The modifiers after the displacement (a, II, etc.) just designates whether it has a remote NV or the NV is on the throttle. I always ordered the one with the remote NV, not because I like or use a remote NV, but because they are very nicely made remote NV assys, and as such are potentially useful for Free Flights or combat models with high pressure fuel systems, or trainers and sport models where they can be positioned to avoid breakage.

I was very happy with the XLS .36 in the Fancher-ized Twister. A nice engine that liked to run...started a couple of times without the battery, OBTW. Didn't test some props I wish I had, but the TT Cyclone 11 x 4.5, launching at 9.7k was really hard to beat. I ran a .272" venturi and a OS .46LA muffler (needed the nose weight plus more). It probably had 20 gallons of fuel through it when I gave the whole plane, engine, prop and lines to Tim, and it would still do 1 flip starts consistently. I think the best string I got was 13 in a row. From what I've read, I would opt for the ASP .36 over either an ASP or Magnum .32. If you're looking at the .40, .46 and .52, get the .52...lighter per cubic inch, being made on the same case casting.

One interesting note on the ASP motors..................

The ones that I got from HK west coast on line store, all 4
motors (2 eah 25A II, 2 each S61A) had the polyamide (spelling) (plastic if you will)
bearing retainers instead of the usual metal ones most all bearing motors come with.
This in itself is a very nice touch.
And one other thing, all motors had a clear plastic type of rear cover gasket. One
should take care if you take a motor apart and note lose one due to not seeing it.
