Fitting petrol tank

Postby RickTee » Tue Nov 10, 2015 12:11 pm

For all you petrol heads :D when fitting the fuel tank do you use tygon for the clunk, seems a little stiff for a 8oz - 10oz tank. Also does everyone use the felt clunk, looks a bit big for such small tanks, if not what do you use and do you all fit filters in the carb line?

One other thing the manual says to use a 16x6 carbon or wood prop, where do you get carbon props?

I fitted a felt clunk in My Acrowot XL Tank.
The Tygon tube was stiffer than silicon tube so made sure the pipe was in center of tank so that clunk bottomed when inverted.
I'm thinking that the clunk will be heavier when wet (or will it?)
Didnt put a filter in carb line (no room and have been advised not necessary)
I've also fitted a felt clunk in my petrol container which may be a bit over the top.
My first petrol engine so any advise will be welcome.

hi rick,,yes tygon in tank,nothing else will do,,if its a small tank and the tygon seems hardish then weight the clunk,a normal clunk is fine just filter the fuel from your can,,as for carbon props try,, prop guy,,motors and rotors,,aerobertics,,pro build,,i.a.d.models,,or apc props works quite well on small petrols and they are cheap and totem may well have them,
a little tip,make sure the centre hole is right size or it can be a pain centreing a bigger hole in a hole

Here's what I'm going for given the advice here and from other club members: 10oz tank with felt clunk no inline filter, Turnigy nano-tech 1700mAh 2S1P 20~40C LiFePo4 ignition battery and 16x6 APC prop. I understand some ppl have had problems using 6v on Cdi units but the instructions with the Saito FG21 do say 6v-8v and on the Cdi unit it says 6v-8.4v, so maybe these are different to the ones the come with other engines.

DLE 35-RA ignition voltage is 4.8v - 8.4v.
I've had no problems using a 5cell NiMh 6v standard Rx pack.
