I am in the process of converting my Super Impress (which was cobalt 400 powered ) to glow (O.S. Max .25). The whole project is coming together without a flaw, but I'm wondering if this might be a wee bit too much engine for this less than two pound airframe. I believe the wingspan is 42". I beefed up all the servos and will strenghten the landing gear as well. Any thoughts on the matter would be greatly appreciated. Thanks

I did that with a 42 inch ws p-51 that used a endo and gb. I used a os max .15 . Plane was just about 2 pounds without battery. Your gonna be way overpowered but it should work.

I converted Super Star trainer, 48" wing span. used OS25. flys great. You can always
trottle back. Better to have to much power than not enough!

i have an e flite mini funtana i would love to convert to glow im tired of waiting for batteries to charge. i dont see it working because surly the glow engine, fuel and tank alone is heavier than the electronic drive parts. then you sitll have to add the rec battery to power servo's

Mr Cox

With the right engine a glow conversion is usually lighter than electrics. A 400 electric motor has about the same power as a .049-.061 glow. It is just a matter of choosing a proper engine and to be careful with the weight of the tank and engine mount etc. The rx battery for mini servos can be really small too.

i dont need any super long flight times but sure would be nice to go glow i think ill try it with my funtana

Mr Cox

A .061 engine and a 2oz tank will give you around 20 min flight in flight time, and a 750 mAh rx battery will last a full day...

I suggest a review of my conversion before deciding on your first one. Its a GWS foamy Mitsu Zero fighter with an integral tank C*x reedy mill.

You can cover the sanded foam with dilute white glue and japanese tissue. (colored if you like)... then the foam will take lite coats of (yeh thats right) DOPE! [X(] (try this first on a foam cup).

Make needle valve and glow plug contact extensions to retain the full cowl. Be sure to provide air exits at rear of cowl.

Certainly an inexpensive ( in $ and time) intro to conversions.

PS; tip; check the decalage on the zero. Early copies were wrong.
