Ground runs are always very much impressive! 2008 I've seen an R2800 running... now that was an incredible experience!

Thanks for uploading! Your video's are excellent ;-)

@Anacinc Hi there, thanks for watching, and for the comment.

Yes, I caught the R2800 at Flying Legends in 2008 also, that was amazing. I think they may have had two Merlins with the Griffon that year also. I remember they had the Welland turbojet there that year, I stood a bit too close and boy was it hot there! Thanks again.

@100thbombgroup I think the same guys had an R2800 with them at the 2008 show. Im pretty sure Ive got a video of it up here somewhere, IIRC it took quite a while to start. If its radials youre after mateski, buy British, get a Bristol Hercules! :)

I have a Bristol Hercules in New Zealand and am in the process of building up a trailer to run her on. Will post clips when she is finished.

@hanglands I would have a Bristol Hercules if I could find one. And if it was almost free. ha ha ha.

Cheers chumski.
