Status: offline 		Just looking around online, it seems Most 15cc gas motors are just over 2 hp. That not bad.
Wonder if the preformance guys will bring out stroker kits and big bore kits?

I know the bigger 23-30.5cc when they are full mod with a good exhaust pipe can be twice the power of the stock one.
Wonder who will be the first to get 4hp out of one of those babies.... 3hp would still be cool

It's funny tho, my slash is only 0.7hp on 2s... So that new savage should be fast enough for most hobby guys yeah?

The MT2 is ludicrously fast with a .28 I'd love to see it on gasoline

Claimed hp is one thing. I want to know what kind of rpm that engine is capable of. Most gassers dont get over 15-20k (which is pushing it) so gearing might be tricky with an engine like that.

Your brushless motor puts out 0.7hp at 1rpm and at 50,000rpm. A nitro engine only makes 2hp in a very thin range of revs (and the dyno test is EXTREMELY subjective, whereas with electric its just math, so, figure on real output actualy being somewhat less than 2hp), the gearing is actually going to be the trick to this assuming that the motor is up to the task. Already that we know its 3 speed, we're making compromises for the sake of lack of revolutions per minute from the gas engine. I foresee the torque of the gas engine causing problems with these complex 3 speed gearboxes, which will unfortunately be required due to the low final rpm of the engine.

I don't mean to sound all doom and gloom, but I think HPI have missed the mark yet again (just like traxxas and the XO-1), sure this and the XO-1, great technical achievements, but, er....why? What was the point?

As for putting it in a truggy, yakfish, I doubt you'll want to do that unless you can also make a 3 speed gearbox fit to compensate for the lack of RPM.

Are you saying the brushless motor makes 3676 Lb/Ft of torque at 1 RPM?

Status: offline 		I have a goped, don't know if you are familiar with those but I put a Zenoah 29rc on it recently and put a high flow air filter, and an aftermarket exhaust from ROC pipes and it will take a grown man that I am and pop the front wheel off the ground with me on it. I feel certain this engine will have loads of mods to upgrade power. I use CAM 2 fuel in the goped and would do the same here, 110 octane and mixed with synthetic oil. It runs cooler and with high compression gives tremendous hp. This is a very interesting development BUT I too fear what that 3 speed trans means with regard to level of possible rpms and also the reliability of the trans itself.

Source: wikipedia

Horsepower (hp) is the name of several units of measurement of power, the rate at which work is done. The most common conversion factor, especially for electrical power, is 1 hp = 746 watts.


And yes, an electric motor makes the same torque at 1 and 50,000rpm (unloaded)

Lastly, the moeasurement of 'torque' in your formula is highly subjective, that's where manufacturers gain their extra hp points.

Thanks for the assist anyway Steed, indeed, it was more of a theoretical point.

Status: offline 		True, I was thinking of the power delivery curve (linear). And again, I realise its not exactly linear in reality due to physical properties, but the theory is linear, more volts=more rpm at max current.

In any case, errors and omissions on my part aside, the point being that an electric motor is making near maximum power throughout its range, as opposed to engines, which have powerbands.

Status: offline 		I agree !!!!

however my thought is this !

it is Not really fair to compare tho...as the BL systems are much heavier and larger then the nitro systems...compare then in equal terms of power density...... in other words limit the weight of the BL system to that of the nitro and see which makes more pop........... The issue with current nitro is they are small engines.. limited more by displacement then anything else...........The technology just has not been put into the larger sized engines..
