Default question?

Hey
Over the summer i am going to try and build a 1/5 1/6 scale gas buggy.I think it will weigh about 40-50 lbs an would like it to go at least 30 mph but more would be better.I was woundering if you guys have any links or ideas for a good strong motor.
Any suggestions will help. THANKS

wow HEAVY for the scale, i would think you could get it down to say 25 to 35 lbs and youll be much better off. i know your only specking the weight, but it would need to be seriously over built to be 40+ lbs imo.

Don't let anyone discourage you. Thats rule 1. I must say though, for 1/5, you really need to shoot for no more than 30lbs. However, its all dependent on material used, and what engine you choose. The dilemma is this, the more it weights, the bigger the engine, but at a certain point, the engine itself is too heavy.

I have built a 1/4 scale buggy that weighed in at around 70lbs.... Trust me, the weight makes designing harder. At the time I built it I had no equipment to weld aluminum and went with steel tube. The chassis came out great (if you ask me) but was too heavy, if I had it to do again (which I fully intend on another 1/4 scale build) I would by equipment to work with aluminum and cut the weight nearly in half. Because of the weight, components had to be structured and over-designed. If you can, use aluminum and try to keep weight to a minimum(30lbs max), this will make things alot easier. And word for the wise.... If you are thinking building your own will save you money, chances are it won't... It can cost ALOT more. If you want to do it for the experience and enjoyment, there are many on RCU as myself that would like to help and see what you come up with. Good Luck!

I am another member who would like to see you go for it. One of those engines around 30cc might yield enough power to move a heavy buggy like that, although the heavier it is, the more torque it will require to get it going. Overbuilding some of the drivetrain might indeed be necessary. You could also look into a pocket bike engine.

Don't sweat the 'underpowered' issue. The 23cc Zenoah motors are capable of moving a 40 lb scooter and 150 lb rider at 25-30 mph; the highly modified 30ish cc ones much faster.

Ryan is right. I had one of the little crotch rockets and it would move on for its size.

As many people have suggested me to do, a hobby grade engine will surely work well. However, as Reiko mentioned, perhaps a pocket bike (~49 cc) may be more tuned for what you're building. IMO, the latter work quite well --> http://www.rcuniverse.com/forum/m_5342488/tm.htm
