Thread: Peterf's 1/4 scale Falcon Models Tiger Moth

Isn't that a Practical scale ?

Ahh! Peter so we will soon have two in that scheme. I am going in for G-ADNV for exactly the same reasons, no ant spin strakes 😃

Just the motivation I needed to get back on my Tiggy.
That's some good progress and looking fantastic.
Have you decided on the colour scheme?

Hmm India? UMS Perhaps? They already manufacture the Siedel/Evolution radials

Were they not being made in China ? The initial batches were made in UK but later I heard the production was moved to China.

JB weld tubes arrived mid week and having cleaned the parts very well with soap and water, then nitro cellulose thinner and in the end with Meth. Parts were allowed to dry out overnight.

Next morning mixed a small batch of JB weld and applied that liberally on the parts to be joined. Care was taken to see that it did not go in to threads.

The tiny broken part was taped up to keep it mated and in correct position. Tape was removed late in the night when I returned from work and all looked to be in good order. For good measure further 24 hours curing was allowed before handling the engine and the glued part.

Once the glue looked hard enough tried to mate the carb and saw that the glue fillet on the mating side was interfering with the carb body. Having taped the carb plenum to prevent debris the fillet was sanded and the little casting on the carb outer body was also sanded and filed a little to ensure there was no interference. Once done the carb was bolted back. No attempts were made to dress up the glue filled under the bracket .

As of now it looks good. Will mount the engine back and fly the model the coming weekend and see if it holds. From the looks of it, it should hold.

In hindsight I think I can build up a fillet under the bracket after roughing up the existing JB weld, that should provide some more strength

Gents I have no intention of taking any heat source anywhere near that case. If it was an OS I may have considered that but not with an ASP.

Yes have already ordered the JB weld, will take few days to come in. Will update here once I have worked on the engine

Having reread your suggestion, I think that bracket idea should be doable. Will fabricate one in brass first to see if it works. If it does I will get one made in steel. That bracket along with the original piece glued in should hold the carb good enough.

The engine is (or was) on a Cub so would not experience much of G forces, and the engine being an even twin has advantage of very low vibrations.

Thanks Denis for putting the pictures in the thread.

Thank you all for your valuable advice.

I will try with JB weld and if it gives away (and the engine survives) then I would get a petrol conversion carb from Morris mini motors and make the engine full gas conversion from the current glow CDI.

The Aluminum solder/weld had occurred to me but I discounted that due to risk of case distortion.

Thanks Gents for taking the time and trouble to look up the album.
JB Weld or Devcon Titanium putty is what I have been thinking to try out.
The bracket that broke is what ensures that the carb throat is aligned and seated in the intake. Therefore don't think some other fixing point may not work out

Unable to post pictures of the damaged engine from my phone. Will update the thread with relevant pictures as soon as I can. Pictures can be seen at my album titled odds and ends. The last three pictures.

An unfortunate low level incident resulted in the damage that you see to the ASP 160 twin.
Other than changing the case itself what other options could I try to get the engine running again?

I tried ordering from some UK retailers, 10 m Natural Solartex was out of stock. Same with Balsa USA. Ended up ordering from Tomodelcz. Should see me through for some time

Thanks Chris. Looks like I misread your post and thought you were also working on a Fox Moth, hence my question.

Chris what size is the Fox Moth please?
