Vega V Twin Aero Glow Engine

This is my version of the David Parker V twin model aero engine from 1986 issue of Model engineer.
Capacity 9cc. Approx 100 hours work machining from stock material and countless hours to master I may add!
There are still carburation issues to sort but otherwise a finished project.

Very good job...

Very nice work. Runs great.

Thanks. I did pick quite a complex project for my first aero engine! Was satisfying to complete it.

Deep respect my friend..very nice job!!! sweet run.

[@creast56]

Many thanks. It was a very challenging first 4 stroke aero engine. I don't make things easy for myself do I?

[@valic000]

Sure not!! But the reward is then even sweeter when t finally runs after so much work!!! Really, a very good job my friend!!

Really nice build of the Vega. It looked in the video that you used aluminium for the cylinders instead of EN8M as specified? I had thought about doing that, but I couldn't see a cast iron liner in your version. Be interested to know if you managed to resolve the carburettion problem or if you have flown this motor.

[@creast56]

Thanks for your comments. The cylinders do have Cast Iron liners as I didn't have much success doing DIY case hardening on the first steel versions so I went more traditional. I did improve carburation but have not flown the engine. It would be a travesty to crash it :-). It now sits on a display unit.

it runs better than mine, not sure if both cylinders firing as one is cool. like the way you did your carbs, seems to rev. up and down well not sure why you are unhappy

[@creast56]

I am not sure what you mean by both cylinders firing as one??? As for the carbs, it didn't respond as snappy as I would like and after running each cylinder separately I knew there was more potential response in there.
