We have just finished running in both motors but bad weather has prevented any track testing. We have a big meeting next weekend so hopefully will get to see how good the new mills are :nod:

Any pics of these new engines? I raced my A52 for the first time yesterday with the 801 pipe. The motor performed great had awesome power tons of bottom end. Had 2 flame outs in heat race changed from OS P3 plug to Werks 5 plug and problem solved. Too bad its may be my last race of the year with it. I Look forward to getting another one of these mills for next years season.

Ran some more fuel through my Argus today too. Getting a better feeling for it with the 0801. And so far, it seems much heavier on bottom than on top, but top is still decent.. Also still have very high temps if I run the SC8 with the body on..

If the B52 has even more power and especially top-end than the A52, I'm definitely interested.. Couldn't care less about run-time..

Heres a pic of external veiw of the B52, nothing of the internals that I can find. External the only thing changed is the cooling head.

So it looks just like the A52 other than saying B52 on side of case. I was curious if there would be color change or something. Cant wait to hear more.

I ran my Argus yesterday in its first race and I seemed to have a ton or speed and torque with just 1/2 throttle. Though the engine performed great I was chasing traction issues at the track all day.

Any updates on new Argus motors? I assume they use the same carb. But do they all come with just one restrictor and what size?

My guess is the A52 stays the same. The A5 will pretty much be the same as the Alpha red head. The B52 sounds like its going to be a killer truggy motor, Different Crank and timing changed to get the top that the A52 lacks. Probably almost identical to the new Alpha green head...... As far as I know, no change in the carbs.....

Restrictors are still just the 8mm same as before. They will ship with a T3 plug included. We had a chance to run the new motors over the weekend, they were still too new to make proper comparisons against the A52, our team drivers preferred to stick with their A52 after practice as they hadn't quite loosened up enough. I ran the A5 on finals day and liked it, the bottom seemed a little smoother than the A52 but still plenty low down and top end was good also, fuel economy didn't appear to be any better but as i said they are yet to fully loosen up.
Unsure about the B52 just yet, will have to drive it for myself, this was the tightest of the 2 motors,

The A52's were screaming, they were as fast if not slightly faster than any engine we raced against :nod:

Are you guys sticking to the 8mm restictors or are you going smaller for better run time, on the A52s

Rcrenew 10-24-2011 07:47 PM

Until we map out the timing numbers on the new engines we really have no idea what they are similar to. Number of ports dont tell that much alone on how an engine will perform. But based on the quality and perfromance of the A52 im guessing the new mills will be a killer addition to the Argus line. :nod:

We have found the 7mm to be the best all round for truggy, and 6.5 or 7 for buggy. 0801 or go 2072 pipe are good but will be trying the Alpha 2090 pipe soon

Herrsavage 10-24-2011 10:43 PM

Very keen to hear more about the B52.. Keep us posted..

Kevin_M 10-31-2011 08:53 AM

Any updates on the A5 and B52? How is the testing going?

ArgusNZ 10-31-2011 10:06 AM

sorry nothing new to report this end, bad weather has prevented any track time, i am planning on getting some more tanks through it this weekend weather permitting!

Thanks Lance. Very hard day that day, thats for sure. Had terrible electronic issues causing me to miss heat one and heat 2 having a flame out from not getting much practice for tune. In the main started second to last and fought my way up. Engine done its job and all i had to do was keep it strapped to the ground. Everytime i take it out it gets faster and faster.
