hi all,

i'm an electric flyer and i want to go glow. no experience in glow whatsoever.

i have a GWS e-starter which i hope to convert to glow. unfortunately, the smallest engine available here is a thunder tiger GP .074. (i'm in the philippines)

please note that we only use castor oil and methanol here. nitro is too expensive.

QUESTIONS:

is it too much power for my plane? even at low throttle? i don't plan on doing verticals or any 3d on it.

is there a prop size i could use so i have more thrust instead of high speed? i want to maintain the plane's "parkflyer flight characteristics"

I don't think you will have to worry about the TT making too much power, I run mine on 25% and its not a Norvel. It is kinda heavy too. On the plus side mine idles very well and its really quiet. I have been using an APC 7x3 with great results on a texaco type model.

thanks for your reply muddy69.

what did you mean by 25%? throttle or nitro content?

also, what did you mean by "it's not a norvel"? is your engine a TT07 also?

sorry to bombard you with stupid questions. don't much about the glow jargons

He runs his TT07 on 25% nitro and it does well ,,the Norvel .074 is a MUCH more powerful engine and lighter too,and probably louder,, it is said to have the power of a .10 size engine,,where as the TT07 is a good reliable engine with a good idle but not as much power..nitro is very common here and we tend to experiment for the best %,the higher the nitro the better up to about %35 then you start wearing things out faster than normal, mostly we run between %20-30 nitro in the small engines and about %10 in the larger .40 size engines..Rog

Yep. what he said

I have run my TT07 on 5% nitro with no problems. I haven't tried straight fuel, but it will probably work okay.

I usually use a 7*3 prop, which seems to be about the best all round size for these engines. If it's too much power for your plane, then throttle back. TT07s throttle really well.

thanks for clearing that up.

all your enlightening posts are very much appreciated
