ANY COMMENTS ON HOW THEY NOW RUN, SINCE THEY DID NOT GET OFF TO A GOOD START, Im thinking of buying a .38 but have seen bad things in the past. How are they now?

Thanks

A friend got a MDS in the summer and it took forever to be able to idle and transition due to the real long break in time, Lots of dead sticks too. IMHO you would be better off with a Thunder Tiger pro .36. I've heard great things about it and is around the same price as the MDS

Pure 110% junk. Tw local hobby stores quit selling them since everyone he sold was returned.

I now have three of them, a .40, a 2.18 and a .68 that due to weather I haven't got to run yet, the .40 and the 2.18 run absolutely perfect on Fox 5%-50/50 fuel and a H9 Super Plug and I'm willing to bet that the .68 will also, it's in my engine test stand ready to go with a 12.5x6 Graupner on it.

sINCE i HAVE DECIDED TO JUNK THE MDS IDEA, I AM GOING TO GET A THUNDER TIGER .36 TO PUT ON MY LT-25. hOW DO THIS ENGINES RUN AND WILL A 9X6 PROP BE OK?

Sorry about the CAPS LOCK since I just relized I had it on.

Thanks

should run good with lots of power but a 9x6 might be a little small, A 10x6 might be a little better.

Best of luck

Good decision to ditch the MDS idea. I'm sure you can get them to run very well. It's just that I have never seen it happen The guy at my lhs just laughed when my friend mentioned that he had one.

10/6 on a .25? Is that not a bit much?

You missed a part, We are talking about a 36 not a 25

My MDS 40 Pro runs great all day long. Never had a problem. It pulls my 7.5-lb trainer around just fine with an APC 11x5. Later.

I think that your opinion of MDS depends on luck. Some are just awful, while others are ok, so if you ask someone who's had one, what they're like, you'll get one of two answers. That said for the same money I'd go with the TT36 if I were you ;-)

I have the .48 FS Pro and it runs great. The throttle responce and transition is excellant......Brian

I have the .58 and it runs great. Only problem is it drains a 6 oz. tank a bit faster than a .46 and it won't shut down when the carb is closed. Other than that it has run perfectly. It pulls my TT profile Extra verticle like a rocket at 5.5# with a 12/5 zinger.

Even though I do enjoy the .58 very much, I bough it because of the size, which is nearly the same a .46 but more power. But with a .36 available compared to the .38 I would suggest the Thunder Tiger.

I had an MDS 38 on my LT-25 trainer, only problem I ever had was, it wouldnt shut down with the throtle untill I realized it had no o-ring in the carb, still runs good, Im going to try it on a Dazzler that I am finishing up this week.

I have one of the old original run of MDS engines, the 46 Blackhead. It's still going strong after 6 years of hard use turning an 11x7 APC prop on a GP Corsair. Had about 3 deadsticks in the first year but never another in the 5 oafter that. I've only changed the glowplug once, about 3 years ago. This is one h*lluva strong engine and idles lower than any other in this class that I've had. It always starts with a good prime and a single backflip of the prop.
They're not for sissies though....
Ok, just kiddin guys,
Heh, heh.....

I have 2 pro 48s. Had problems with both, until I took it to the new hobby shop in town. I had assumed both LSN would be in the ball park from the factory, NOT! one was out almost 8 turns the other over 6. I played with both needles and wasted 2 gals of fuel. Never thinking that the high speed needle physically effects the low end needle. So if the HSN is at the recommended 2 1/2 turns the LSN is no where near seated. OK long story short they both run like champs now. They don't make quite the power some of the others due but I would recommend them for someone on a tight budget that needs an engine for a trainer. BTW one has the new carb, the other has the old. Always happy to help if I can. Garry

Your experience pretty well matches mine. A student brought one of those Xtra Easy trainers with the MDS .40 on it. Deadstick deadstick deadstick, usually within 30 seconds of taking to the air.

I listened carefully, and could hear the engine slowing down gradually, a sure sign of too much fuel. Two or three guys tried tweaking the high end repeatedly, only to have the engine deadstick. They ignored me when I suggested the idle mixture was way too rich, but another instructor said the same thing, they listened, and the engine ran much better.

I only can give thumbs up for any MDS. I have 12 of MDS from a 28 to 1.48 and all of them running strong and great. No deadstings or any other trouble. all MDS engines with problems send them my way.

How about a Mag .36? Same weight, they say 10% more bhp than the TT. I have 4 of the new Mag's, and all have run strong. And only $60 - $69.

I have a TT Pro.36, good engine, runs great, good transition, lots of power. APC 10X6 prop. 12,500 Rpm. I find the high & low needle settings a touch finicky so you have to be a bit patient there.
As for the MDS line, I've never owned one and have only read up on them, good and bad. I think they are probably an alright line of engines,may be not quite as user friendly as some other brands. I believe a number of fellows out there really don't know how to preform the proper engine adjustments and are not breaking in their engines correctly.
If you are new to the hobby, you may want to purchase something other's are using at your field and are familiar with to assist you.

the carbs on MDS have more leaks than a Welsh farmer and the con rods are made from fudge. hey will run, but its not worth the bother.
a REALLY! good option is the LEO 37, mine is the strongest engine i have in this class and it runs faultlessly. for the same money as MDS you can't beat it, in fact, if kicks ass to any engine in this class. untill the West comes out that is. I also have 2 Magnums which are ok, but the bearings arn't up to much, the SC is a Magnum too. I hear only good things about Thunder Tiger

I wonder why my three MDS' have carbs that don't leak, rods that don't bend and they run and idle flawlessly.

either you have one of the very new ones, or you have castor gumming up the holes, or you just don't expect it to go like the clappers. its mainly the 38 thats the dog
i didnt say bend, the end wasnt bushed and it wore out 3 times in a year
