Russian MAC/MDS 61 engine

Update: it broke! Unfortunately the crankshaft on my powerful MAC/MDS .61 shattered in-flight. This may have been because I was using a heavy composite glass-filled plastic prop rather than the wooden props these engines were probably designed for. Still, I got more than $49 worth of fun out of it while it lasted!

When I saw these engines advertised for $49 I thought "why not take a chance" and ordered one.

Over the years I've wasted lots of money on "bargain-priced" engines that end up as paper-weights, so I wasn't too optimistic that this one would be any different.

In fact, it was because I'd bought so many cheap model products that have turned out to be worthless that I'm starting the RCModelReviews.com website.

See the video and decide for yourself if I got a bargain with this engine or not.

Sometimes it's nice to come out a winner (for a change)!

that thing rocks ,man! do you recomend this engine ?do they sell to usa? do they have bigger ones ? OR is it junk? By the way ive been reading your reviews and thanks for the insight and come and fly in oklahoma !

@dsldrvr69 It's a very powerful engine -- but there have been some design trade-offs to get all that power and the main one is that the crankshaft is pretty weak (a very large gas-passage down the middle makes the walls too thin).  I ran a heavy prop on it and the crankshaft broke. Stick to a lightweight wooden prop though and it would be fine. I may buy another.

All you seem to fly there is trainers, whats up with that? :) Get some proper planes! not slab sided ugly things!

[xjet]

@vanepico Nah, we've got lots of different planes, it's just that in the "fun per dollar spent" area, it's hard to beat an overpowered trainer. Check my channel for lots of jet-action, 3D profiles, Mustang P51D, electrics, DLG, etc.

hi there totaly random question really but have you any idea how or what paint to use to respray a nitro plane as i wanna respray mine but it has that plastic covering shit on it. now i can fly my plane perfectly i want to start making it look nice :) thanks

[xjet]

@3halljo You would have to strip off the plastic covering then apply a few coats of sanding sealer or grainfiller (sanding after each coat) then a final application of a suitable (fuel-proof) paint. I've done it before but it can be a slow and messy job. The results are worth it though because you don't have to worry about that film peeling off again.

Old man at the controls is an awsome pilot.

Ive had my MDS 58 for around 10 years now and have run it a few times but thats it... Never flown ... However I have just bench tuned it and it now runs fantastic so its going in the Koyosho Cap232 that I also bought at the same time as the engine and its going for its very very late maiden in a few days ... Hope its almost as powerful as yours Bruce ...... Why so long waiting for a maiden..... Confidence and playing around with planes like the AXN which just make flying way too much fun ...;o)

@Chilly2299 It's a home-made tuned pipe.

i have an MDS .28 Marine engine and i have been running it for more than 5 years...my friend has a PRO21M thunder tiger in the same boat and i can pass him with my half throttle :)

Hey, Bruce what muffler is that, does it comes with it, or it looks to me like a Super Tiger header. Thanks BB.

[dsldrvr69]

thanks for reply! i will consider , after all its cheap!

I've heard many differing tales with the MDS brand. I have a .68 PRO in a Goldberg Tiger 60 I built almost 15 years ago, and that engine starts every time with very few needle adjustments in that time.....still. The thing won't quit, and is still extremely reliable. I'd buy another one in a heartbeat.
