hi ive never had an asp engine before what are they like are they good runners?powerhouses?

Funny you should ask this. I just mounted one that I have had for twenty years. Fired right up. They are very good inexpensive engines that produce excellent power. The older ones had carb problems, but the new generation carbs solved those problems. Hope this helps.

My brother has one (that's fixing to be mine ) on an ultimate bipe (.91 2st) and it's a screamer. Very strong engine. He runs (I believe) a 14 X 8 prop on it, and it will pull the bipe around like it's nobody's business. Never had an issue with it--great running engine. Another guy at our field has a .75 asp and it's a great running engine as well. My understanding is that they are (were) made by magnum. Don't know if that's true or not, just what I've read.

ASP certainly used to be manufactured by ASP -- it was a European engine & it required low, or zero nitro fuel. I believe that current ASPs are made in China, to the original ASP configuration --- maybe.

The old ASPs were inexpensive, but ran well as long as you kept nitro out of them -- I'm not sure how the Chinese ASPs work with nitrated fuel.

somebody here help me with this if you can.i have a 91asp redhead,it is the older one i think,it has the round cylinder head,i read something once that menthioned about the markings on the box something to do with the colors?this one has a silver stamp with 91as in it,box markings say I.S.C international Indianapolis IN.address.I'm not sure if this one has the new style carburetor or not.it runs pretty good.it came with the extra head shims and i was told to put two in so i can run 10%nitro.anyone with any information or any links please post them...thanks

My brother runs his on 15% nitro, and it runs great. It did have a bit of a heat problem at first--due to the fact that it was cowled, and under propped. Once the right prop was put on it, I don't believe he had any further problems.

ASP are same as Magnum and SC engine, they are produced in same factory Sanye Mfg in China. Reliable, easy to handle and strong engine. Need between 10 and 15% nitro. Economical engine.

A friend of mine has a 15 year old ASP 40 and it really screams. I'd love to own it if he'd ever part with it.
P.S. I prefer the Hurricane myself but the Spit did out-perform it.

I have an ASP 75 for my 4*60 and have only bench run it at this stage. It started easily and was really easy to run and tune, idled well and transitioned well. This was all on fuel with no nitro. At this stage I would reccomend ASP's a couple of the other guys at the field have them and they run well

ok then thanks guys
