I have a number of Glow and Gas engines for sale. I am gradually going all electric and no longer need these engines. They are all used with little time on each and I am pricing them at about 50% of new.
Engines available are; (2) Saito 125A, YS FZ 70S, XYZ 20cc, DLE 20 & 30, RCS SV 26cc & RCGF 26cc
I also have a new set of 1/5 scale P-51 retracts, main and tail with a door sequencing valve. The gear, consisting of retracts and struts are Robart and the sequencing valve is by Dreamworks.

Spektrum's Basic Methods to Set Up a New Transmitter if you don't have a basic template
RC Transmitter Mixing This is a long video on mixing basics, but watch it all as Robert does and excellent job of telling what, how, and why to do mixing. He starts with Transmitters in general, but then shows how easy it's done in a Spektrum.

Rain or Sleet may stop members from flying, but not when it's Snowing (video) and Photo Gallery.
Quick method to estimate size of motor to replace a glow fuel engine is to multiply cubic inch displacement by 2000. For example, if engine is 0.40 cubic inches, multiply 0.40 by 2000 = 800 watts. Also see this wattflyer article.
Is your battery a year or two old and after charging the voltage is normal for a full charge, but when flying the power seems low? It may be that battery internal resistance (IR) has increased, which acts to reduce power (watts) delivered to the motor. Read Power Loss Due to Battery Internal Resistance to see how this works. The extremes of low and high internal resistance (IR) are explored, but your battery may be somewhere between these extremes. It appears that longer battery life is experienced when battery cells are only charged to 4.0 volts and discharged to 3.85 volts per cell. Voltage and battery life may vary depending on how you fly.
