Title: Diesel power.
Post by: scrowoash on March 25, 2017, 10:12:10 AM
Hi Everyone,

I need some advice. I want to build a Dick Sarpolus half a Spitfire. I was wondering if a 1cc diesel will be sufficient power?
Where I live in Zambia, I cannot obtain high nitro fuel for a TD engine but making up diesel fuel is no problem. The engine is a ED Bee mk1.

Thanks in advance.

Hi Scrowoash,
How much info do you have about model diesels? Are you aware that you need ether in your fuel. Ether is difficult to access in some countries but is essential in diesel fuel.

Yes I can get Ether. Being involved in agriculture here, the chemical suppliers we deal with are able to supply as a favor.
The other option is John Deere starting fluid which is available here and has the highest Ether content of all starter fluid manufacturers.

I had no idea what this model was so I looked it up, and it seems to be a 31" CL trainer, designed for a TD049. Even that seems underpowered  and a Mk1 Bee will barely move it. You will be spending a lot of time running backwards, I think!

Hi Billdennis,

Yes, after some research, i have also found the Bee to be unsuitable. I have found since i posted that question some 30% nitro fuel in South Africa which I am able to road courier to me in Zambia. 5 litres will cost me 60 bucks including delivery. I have a tee dee 051 which ran once since i got it new in 1981. Now that i have found fuel, that is what i plan to use.

Most of the high nitro fuel over here does not have as much oil as your TeeDee requires.  The oil needs to be 20% and at least 1/2 castor oil (ricen).  All castor would be even better.
