This is the Reedy 121VR .21 competition nitro buggy and truggy engine from Reedy! This engine is a powerhouse, and is also the 2009 ROAR National Champion which powered Ryan Maifield's Associated RC8T truck to a top qualifying position and then victory in the A Main event! Ryan then backed up this win with a 2nd place finish in the 1/8 buggy A Main event about an hour later. The tuned pipe used by the AE team drivers on this engine is the EFRA 2035 pipe from Team Associated or Thunder Tiger.

What a engine!!!!! I've run this thing twice a week all summer long including 3 weekend events, with 3 A-Main finishes two 1st and a 3rd. Engine now has over 10 GALLONS in it , still has lots of compression and runs strong! 7min run times, 250 to 280 temps. Great motor! Great price!

only issue i have found is the rear bearing doesn't last. 1st engines bearing went with around 10 litres on it. The 2nd engine went with around 5 litres on it. i have had 2 seperate engines bearings fail as well as 2 other engines owned by other drivers have the same issue. The rear bearing wasn't expensive to replace but the piston and sleeve that was destroyed was.

All I have to say is this motor is probably the best 3-port race engine out there... I got this motor for free from a guy at my lhs and put a pinch on it and all I have to say is it will keep up with everyother motor out there... It doesn't have the best run times with mine getting about 7-8 min a tank down at revelation raceway but thats plenty fine with me. While i do only race the novice class this motor has aleady helped me win a race and place top 3 everytime out... I love this little motor... All I have to say about it though is don't care to run it hot... I run mine anywhere between 270 and 310 degrees with no problems and still plenty of compression after having the motor pinched... I have even talked to a local AE and Reedy Sponsored driver and he even says he has ran his motor 300+ degrees all day long with no problems... If you are on a budget then get this motor... You will not be disappointed at all...

I love this motor!!! I've got 3 gallons on mine and it'll keep up with any os motor out there. Some of the tuning issues could be attributed to the fuel they're using. I use Sidewinder 30% strike team fuel(purple stuff) and os p3 plugs. My motor runs around 250 and gets around 8 minutes a tank. Would definetly recommend this to anyone.

Forget the O.S. Save $50 and buy a werks B5. The reedy motor is good. I tuned on up the other day and it ran just as fast down the straight as the Speed and he could almost triple out of a very difficult rhythm section. It temped at 260*F running O'Donnell 30% fuel. Two gallons through it and has not flamed out once, since I tuned it.

I race a Reedy motor, and all you need to do is seal it,and don't be scared to run it hot. Just like every other motor you need to do some homework and tune it properly. I called Associated's tech support and they are awsome and very helpful. They said to make power it runs between 270-300 all day long, and if you tune it by temp it will never run right, so do some homework, tune it correctly and save your self 100+ dollars. Buy a Reedy. I'll be buying another one very soon.

Great engine, especially for the price. Idles flawlessly and tunes easily. Nearly 10 minute run time in my Truggy! Will buy another soon!

this engine is great, its a little picky at first. i was running it with the o.s p4 super hot and it was a pain to tune so i went with a med plug and boom nice idle and everything but mines runs at 210 F a little rich, it has great bottom and top end.

So far so good. Very easy to run in and not one flame out. Just came back from a 2 day offroad race meeting and this engine (owned by another driver) TQ`d and won both Buggy and Truggy classes. It won these against pretty much every engine manufacturer you can name and in the Truggy final it won by 13 laps. Very nice engine for anyone thinking of purchasing. O.S. P4 plug works very well with this engine.

Reedy 121VR .21 Off-Road Competition Nitro Buggy/Truggy Engine
The motor gets decent economy and when tuned for my liking does everything I need it to. The problem is, that temp in which it performs is around 260-280. It is much different than other motors I've had in that respect. This probably leads to the mixed reviews. Either way, I willl run it until it blows up. Another thing I will try next is going up a tooth on the clutch bell as the top end is a little flat, but power is smooth throughout so that is nice. It is hard for me to give it above average rating as it runs so hot. -//- starting to tune this thing in. What temps does this motor like to be ran at? They seem a little high in my opinion. Seems like 280 is where it will have enough power for a truggy. Anyone else had the same experiences?

What are you talikng about! Both of mine run awesome. Easily kept pace with a Vspec and Ninja last weekend. -//- Ryans 121 was not box stock. Team drivers here who attended said that his engine was easily hitting 4000 more prm at the top than any toher 121. It is modded. -//- The bottom end needs to be on the rich side to get the most out of it. -//- Yes anywhere between 240 -280 is what this motor likes. I run it in my truggy and it has plenty of scoot. Great bottom end. -//- By the way, the manual syas a plug is included, but there isn't one in the box. Pick up an OS P4. -//- engine has great bottom end, and a good top end. Pulled the truggy over the Double-Triple with ease. With it still at the factory settings, it runs strong and idles great. Runs about 10 min on the track with the 2035 pipe.

Got this motor about a month and a half ago and so far have put about a gallon and half in it. had to send it back to AE cause it seemed like the rod already went out but i guess they said it was fine and they sent it back to me. I put it in my xray 808 and with this motor and the ae 2035 pipe my car weights 3280g. and i can keep up with my buddys losi 8 with a toro. its neck and neck on the straights. This thing is super fast. BUT it seems to me like it runs how. it runs 280 for me. some people say that is what it is going to run so im going to leave it. currently im running a p4 plug and its been on that same plug for about a gallon now and the compression seems to still be good so i guess the motor is running where it should be. Over all the motor is not bad. a little weird if your use to running novarossi motors but not bad.

I found this engine very easy to break-in, although when I took it to the track, putting a race tune on it was difficult. This engine has a nasty bottom-end lean bog, even when the needles are set pukingly rich. Furthermore, no matter how rich you get it, the temps always seem way too high. Team Associated's race team manager, Brent Theilke, had this to say: "Here's how mine tuned in Southern California: Plug = O.S. P4 Pipe = Factory Team 2035 Restrictor = 7 mm Head Shims = 0.50 mm Fuel = Sidewinder 30% World Blend Top End Needle = 2 1/2 Turns Out From Bottom Bottom End Needle = 3 1/4 Turns Out From Bottom Temp = ~250 Degrees F" Copied that setup exactly (but with a JP-3 pipe, and the needles set an hour richer on both ends because I live in a higher elevation than California), and the lean bog problem is still there. (Carb has been sealed, as well as the backplate. Fuel tubing and tank are brand new). Perhaps you MUST use an AE 2035 pipe in order for this engine to behave itself? It sure as hell doesn't work a JP-3.

i agree with that, i run one i my hyper 9 and just last weekend at nitro pit track i flogged a v-spec, GRP, Orion. GO, BOSS, NINJA JX, NINJA MR -//- DID ANY OF YOU GUYS EVER THINK THAT SOME PEOPLE KNOW HOW TO TUNE A ENGINE ( RYAN MAIFIELD) and some don't ( MUGEN RACER) LOL. I Run This engine in my Kyosho and it flies past engines such as V-Spec, Orion, GRP, Castor, GO. -//- nah most people wan't a engine that will last more than a v-spec ( 1 - 2 race weekends ), and maybe you got it mixed around. MAYBE THE ADVANCED DRIVERS CAN DRIVE IT FAST AND THE BEGGINERS CAN'T... I Have had no problems with mine and i have done 20+ litres on it -//- wake up this thing is slow i know people who sold theres after only running it once . unless you have it modded it has no top end at all. it is a good engine for someone new to the sport and thats all

I don't know what you are all talking about. This engine is awesome. I run it in my truggy and it has more than enough power to keep up with pricier engines. I am not the fastest driver around, but last weekend I was blowing past VSpecs, Orions, and Novarossis. Im gonna get one of these for my buggy really soon...
