Hi All, I would be interested in fitting the sprung unit. Probably will add a good kilo or so, which will equate to a min pilot weight increase of about 7 kgs. Dave Goldsmith's H-36 MkII VH-GFG also has the sprung tailwheel. It lives between Bacchus Marsh & Bendigo. >From a GFA airworthiness point of view, exchange of the rigid wheel for the sprung one would not constitute a mod if the factory parts are used, but should we decide to build them locally a mod would be required for each aircraft to which the new assembly is fitted. This is easily achieved; we have done it before with oil filter installations.

The sprining consists of two rubber blocks which take the bumps out of the tail compared to the non sprung version. It does raise the tail slightly. There is a drawing on page 4.10 in the H36 parts catalogue. I did replace the top section on GJD when I imported it as there was a very slight bend in the vertical spindle and this caused tailwheel shimmy. The faulty part is still in the workshop. There's no place like cloudbase.

I think the sprung wheels may also reduce the "bunny hopping" on rough runways....can anyone enlighten me as to whether this is the case or not? Last time I saw a sprung one I didn't think it would be particularly difficult or costly to manufacture - perhaps we could get some plans drafted from one of the dimonas with a sprung wheel and see about getting a few made up with appropriate approvals. How many of you would be interested? cheers Rob PO Box 129, Lawson, NSW, 2783. mobile <chrome://skype_ff_toolbar_win/content/cb_transparent_l.gif> <chrome://skype_ff_toolbar_win/content/flags/au.gif> <chrome://skype_ff_toolbar_win/content/space.gif> <chrome://skype_ff_toolbar_win/content/space.gif> <chrome://skype_ff_toolbar_win/content/arrow.gif> <chrome://skype_ff_toolbar_win/content/space.gif> <chrome://skype_ff_toolbar_win/content/space.gif> <chrome://skype_ff_toolbar_win/content/space.gif> <chrome://skype_ff_toolbar_win/content/space.gif> <chrome://skype_ff_toolbar_win/content/space.gif> <chrome://skype_ff_toolbar_win/content/space.gif> <chrome://skype_ff_toolbar_win/content/space.gif> 0429 493828 <chrome://skype_ff_toolbar_win/content/cb_transparent_r.gif> ............................................. ________________________________ From: Ian Mc Phee <[email protected]> To: [email protected] Sent: Wed, 27 January, 2010 11:39:22 PM Subject: Re: [DOG mailing list] Dimona 1984 Interesting about tail wheel mod from Michael - sure gives smoother ride. You mention the heads/valves lasting only 300hrs. I would recommend to all analysis of exhaust at FULL POWER with lamdameter etc. You may find it is running slightly lean on full power (actually plugs look OK) but gas analysis does not lie. More recently i have been using digital CHT and you can really see what is happening. I set them up so full power CHT rises to about 170degC then very slowly falls. If you bring throttle back just a bit in revs CHT will quickly rise to 180degC and beyond. This proves to me you are running rich on full power- also confirmed on EGT. To achieve this it may be necessary to carefully thin out the end 6mm to 8mm of each the needle in carby and thus achieve the low CHT on full power. (do not think of touching jet) Fuel is cheap when compared to repairing heads. Limbach Tech bull 53 makes mention of max on climb of 180degC (forget what max the manual says - that is stupid value) Also Tech bull 44 (11page edition) is well worth a read.
