| I had a Frog 500 in the mid 50s, I used it to power a Spitfire control line model that I scaled up from 1/72 plans to about 36" wingspan. It went around half a lap before flying in on the lines and plunging into the long grass - unfortunately there was a hidden manhole cover lurking there and the Spit scored a bulls eye, the model came of very much second best in the contest.
Your best bet of a spraybar and needle valve if you want to restore it is John D. Haytree on 01626 852330, he only works part time now I believe its Mon - Weds.
At the recent Guilding auction a Fair 500 had an estimate of £25 - £30, a Good 500 had an estimate of £30 - £50 and an Excellent 500 in its box had an estimate of £50 - £80. I went along to pick up some Oliver Tigers at a bargain price but the place was heaving at 8.30am and very few engines failed to reach their lower estimate. I left with nothing I'm afraid. |
