Status: offline 		I was just wondering if the axial engines are popular because my genuine .28 engine carked itself and the guy at the hobbyshop reccommended the axial .28, he said that all of his mates run them too and i was just wondering if this talk was just to get a sale.
ive installed it and ran about 6-7 tanks through it and i was just wondering if they are a good brand before i tune it to performance.

cheers.

Status: offline 		It's a well built motor but I dumped mine pretty quick. It has no top end as I found out. Repalced it with a SW .26, much faster and better in my opinion. Soon to replace that with a jammin .21. If your just bashing though then Im sure the axial will work just fine for you.

Status: offline 		The Axail engines have alot of bottom end but thats it. Good tuning and good running but a dog for speed. I Had the Axial 28 and a Sportwerks V2 .26 and the SW would smoke it in every way with no problem. The SW is a great engine. If you want a great engine for about 175 then the LRP spec3 cant be beat.

Status: offline 		Any one have any problems with their axail engines pistons disentegrating ? My .32's lower side wall cracked and fell apart after only five tanks including the 4 for break in . I replaced the sleeve and piston only to have the same thing happen again in less then 6 tanks .it happened on the left side if you were looking at the exhaust side of the piston . My axial .28 did the same thing but right at the exhaust port . I'm guessing that the piston bottom slammed into the small groove that was machined in the back plate of the engine . I was wondering if any one else has experienced this problem . I also have a Raceres edge sure fire .32 with a good season under its belt and have not had one single problem besides the mid range screw self adjusting < that was fixed quite promptly with a little teflon tape and ultra black sealent . I've shipped the .32 back to axial and theyre in the process of correcting the situation and as soon as i get a RMA # for the .28 it will be going back as well . I was just wondering if anyone has experienced this phenomenon ? Any input or ideas would help .

Status: offline 		You may want to get a Tsais T-32 pipe-set. This pipe will
help the Axial.28 turn some higher r.p.m.'s. I found the
T-32 is what this motor needed.

Status: offline 		I'm running a JP 2 on the .32 and the .28 would that have anything to do with the piston problem?

Status: offline 		No that has nothing to do with your problem. What fuel are you running and what break in procedure are you using?

Status: offline 		Using o donnel 20% with an os 8 plug ran it at idle let it get up to 210 220 shut down placed piston at bdc cool down to out side temp mid 60's here then repeated for four tanks . it would get about half way through a tank before getting to those temps so all together it was cycled a total of 8 times . after that started runnin it 20 ft sprints at half throttle then off throttle for 3 secs or so at factory settings getting plenty o smoke . got it up to 230 shut down >bdc cool repeat on the third cycle it grenaded the piston . made a funny chunk sound then it was all done .

Status: offline 		Everything looks good except for 4 tanks of idle. Not that that would be the cause but 1 tank at idle is just fine then you start to run it and tune it little by little after every tank. You will be abkle to let it rip after 4-5 tanks. You have had this problem on 3 different engines?

Status: offline 		No just the 2 axials the only problems ive had were the axials first the .32 it did it the first time then i ordered a sleeve piston set re broke in then it did it again then i shipped it off to axial . I had already ordered the .28 because of the price from tower . that engine did it on the first tank after 4 tanks of break in . the other engines i talked about were my main movers that have been great aside from some small tuning and sealing issues . Ive been running nitro for almost 5 years now and have never encountered a problem like this with any engines . O.S / traxxas / Hpi / ofna or racers edge . even the guy @ axial said he has never heard of something like this before .

Status: offline 		I have an Axial .28RR engine already broken it. The only issue that I had was when breaking in and the tank empty, I tried to spin the flywheel so the piston will stay at the BDC, but while spinning flywheel to go through the cycle, the piston will lock at the TDC, so I struggle to free the piston while the engine is still hot to warm. Lucky for me I was at my backyard when I was breaking-in, so I rush to my basement to remove the engine and pull start. But after the breakin period is finished (4 to 5 tanks), I don't experience this anymore. Now I have 8 tanks on this engine it is time for porting.

Status: offline 		I have no complaints with my Axial. Plenty of speed (easy 40+mph) and bashing torque to keep me happy. Feed it good fuel and it will run very well. Mine loves Byron's GEN2 30%.

Status: offline 		My Axial 28RR is now fully broken-in and it is now performing very well, however, I only notice that once I fill the tank full, then, after firing the engine, it runs on the rich side. I don't adjust the HSN and I let it run as is. But when the fuel is 1/4 used, the engine will perform at its optimum and the temperature will hold at 200 to 210 degrees. My concern is if it is normal for this engine ?

Thanks

Status: offline 		You are experiencing the half tank lean syndrome. It is considered normal. You can mimimize it in your situation by slightly leaning out your HSN.
