This survey is made not a long time later with the release of DLE30cc engine; it seems that there is a bit unfair for the DLE 55 cc RC engine. The result also shows that DLE 30cc can get such a high mark is due to two main reasons. One is that due to the price of DLE 30cc is lower than DLE 55cc, and another reason is that there are more people who like to play the airplane with the 30cc gas engine because it is lightweight and with strong power.

But in fact that there are also a lot of RC enthusiasts choose to buy the DLE 55cc engines with higher prices; it did not make a big effect on the sales of this engine. And mBuyNow.com continues to release new engines to attract more customers.

As for me, I like DLE30cc Gas engine more. Because its output for size -3.7HP@ 8500rpm can satisfy for me and the light weight is also a very important element for me to take into consideration. This item with high quality and has won great praise from the RC hobbyists, made for flight design can ensure the best power to weight ratio on the performance of our RC aircraft.
