Default Pt Electric - Glow Conversion Question

I was cleaning out the basement the other day and came across a great planes PT-electric trainer. Don't remember where I got the thing but was wondering would it be possible to convert this plane over to glow? What size engine would be needed to fly it. I think the weight is about 45oz ready to fly.

I'd bet that a .25 fp or LA would fly it just fine.

Default Pt Electric - Glow Conversion Question

I think a glow forum might be a better place for this. For the most part, airframes are airframes; there is very little that differentiates a glow airframe from an electric airframe. Of course you use less material on an electic and more on a glow, but besides that...

Anyway, the power system is what really makes one different from the other, and you're asking specifically about a glow engine in a group primarily focused on electric power. Fine and dandy as long as somebody that flies both pokes around, but a lost cause on a site like The Ezone...

Six cells, direct drive 600 motor... Hmm.. A .25 would overpower the poor little plane and tear the wings off. I'd say a strong .15. This is an old design, so it may not even need to be beefed up to take the banging and shaking from the engine.

Default Pt Electric - Glow Conversion Question

I had posted in the Q&A forum and got no response. The Pt-electric is similar to the PT-20 but it is lighter. I am leaning towards an engine in the .20-.25 range. I am really looking for a lightweight powerplant to put up front. The stock can motor and battery weighs somewhere around 21oz. I think I can find a glow engine that weighs alot less. I'll need to beef up the nose end of the plane and modify the firewall. I'd like to remove some of the wing dihedral and perhaps add ailerons. I haven't built a plane this small in awhile so I just wanted to have some fun with it.
It's been gathering dust in the basement for many years so I'd figure I'd do a little kit bashing.

You might be surprised as to how little extra support yu need on
the front of the plane for a 25. 1/8 light ply will be plenty for
strenght.

I converted one of these and used an OS .25 FP. More than enough power, it would fly fine on a .15. I glued a 1/8" piece of birch ply to the firewall and it needed no other strengthening.
