I agree, most of yours is fairly level and flown where the prop rips

Good stuff on the break in techniques, I grew up in a shop an have worked on an saw inside anything from small model engines to heavy eqpt.

Amazes me how some ppl think their engines with 2-3 bearings an a cpl rings break in for the first 1,200 gallons ( yes I inflated the number but only slightly).


I guess the bearings smooth out?

You mean some actually have more than 1 ring!!??

T.bob there is no risk with the Evolution 58GX. I have been flying my 58GX Generation 1 know for over 6 gallons and it flys my TOC1 Yak 54 30% just fine. Matter of fact I have a friend with a DA50 on a WH Edge, been in the shop know 5 times in two years. Yes you are right about DA's service, impeckable. However, if you get a front line person @ Horizon vs. a manager then yes a little squirlley but nothing that can't be fixed by asking for a product manager. Both motors are very good motors, but I really feel the GX is a better fit for most 25, 28 and 30% airplanes.

There have been alot of head gasket/shattered ring problems from the 58 recently ,,,, ??????????do a search,. I have a buddy that flies with me,, he had his EVO58 blow a head gasket after three gallons I think, they fixed it promptly under warranty,, if anyone has any question pm him ,,, andyt is RCU name,,,

I have a 28% extra 300, I went with the carbonfiber landing gear spinner and wing and stab tubes, I measured the weight of each item down the the gram, if memory serves me correctly for my 200.00 bucks I shaved off 1.5 lbs to me it was worth the money. I did use all graphtech except the spinner. If you get their landing gear buy the new 3d weave design, 50 plus flight and it is still fine.
If you are interested in exact weght let me know. Brenden

Jimmyjoe,
I assume you are talking about my DA50 since I think I am the only one you know that has one on an Edge. Your numbers are somewhat stretched. The engine has been to the shop twice. Once for the upgrades and once recently for the ignition. The ignition damage was my fault as i told you at the field. I had asked you once before not to use me and my equipment to make your points. If you insist on doing it , be accurate. Just be honest and don't stretch the truth.

i had a evolution 58gx on a yak. really good engine.
i had a da 50 on a vision. really good engine.

the evolution does spin a bigger prop than the da. it is heavier though.

i would choose the evolution 58 over the da50 for a 30% sized airframe. i just like to rocket out of torque rolls and the da 50 doesnt do that.


aerowiz.

Makes sense that the 58 would be more powerful than the 50. It is about 15% larger. Duh.

Wouldnt a better comparison be made between the MVVS 45 and the DA50?? They are almost the same size in weight and closer in cc's.
