I am afraid that I disagree with the comments about Doug. They do not reflect Doug's comments or intentions. We are here to offer assistance to those that request it and others that may learn from the comments etc. Doug offers some of the best most practical advice
from his experience.
A Fairmile D had 4 engine
s and props. if you want to recreate it as a true scale model
then that is the the aim.
You are entitled to have one prop, one engine
and one SLA battery
in your boat. it may plane for approx 10 minutes before it slows and drops off the plane. I had such an arrangement a few decades ago in an old MTB, but have learned from it and moved on. I would not advise this arrangement with all the newer motor
types and ESCs available.
My Fairmile D has 2 x Speed 700 motor
s and NiMH batteries
. it runs on plane for an hour or more. My newer Vosper MTB and La Combattante III boats have 2 x brushless motor
s each and the same NiMH battery pack
s - my choice. Other people use LiPo batteries
We respect all modeller
s and their quest to build
'their' own model
s. Nothing wrong with having the best advice
available, so modeller
s can make up their own minds.
