Super Gremlin by Got Gas RC

[corsha99]

A combat gremlin done Got Gas style. Be prepared to scare everyone at the flying field!!

Wingspan: 87 in
Wing Area: 1700 sq in
Weight: 13.5 lbs
Engine: Ryobi 31cc

The Got Gas Super Gremlin (http://www.gotgasradiocontrol.com/gremlin.html) features a 2 piece wing for easy transportation and quick building, full span control surfaces for extreme maneuverability and aerobatics, tricycle landing gear, and best of all, designed for affordable gas power using the Ryobi 31cc engine. See the Super Gremlin in action here. (http://www.gotgasradiocontrol.com/movies/supergremlin.wmv)

Foam wing version uses a tried and true method of covering the foam wing using packaging paper and white glue (paper included in kit). Technique makes for a very strong and light foam wing.

Full kits include all wood for construction including laser cut parts, aluminum landing gear, aluminum wing joiner, CAD drawn plans, and instruction manual. Short kits include landing gear, wing joiner assembly, CAD drawn plans, instruction manual, and material list.

Purchase a kit for only $160. Scratch builder plans are $22. Short kit (plans, main landing gear, wing joiner) available for $45. Visit Got Gas RC (http://www.gotgasradiocontrol.com) for more information

Sorta reminiscent of the plane by Bill Winters a few years back called the Goblin...is that what inspired this?

I have one of the Goblins, flies like crap!

I believe the Gremlin was introduced in RC Modeler mag in 1989.
It has been around a long time. It was even kitted by at least 2 outfits.
We used to use them for streamer combat. Flew great. Cheap too.

My goblin flys fine also. C og G on mine is at 15% of MAC.

Inspired by the Combat Gremlins that used small motors for streamer combat. Loved the gremlin but hate small glow engines. Result is a combat gremlin that is big enough for weed eater conversions. Flies great. Takeoffs can be interesting but once airborne it tracks rock solid, rolls as fast as you set it up to do, and bangs turns. It even flies great without the engine running, just comes down a little quicker.

I bought the Gremlin that was in an RC Modeler mag review, found it
at a swap shop and bought it from the guy that did the review. It
flies great and is incredibly fun. I have built a few others and
surprisingly the original wing has still survived!

Great job. What White Glue were you using? I use Weldbond. Same method of construction for over 30 years.

Now I find glass fibre and carbon fibre are even better.


I have two forward swept wings using the same method that will be finished sometime this winter.

Just use good old white elmers glue. Only difference between the white and yellow is water content. Agree that composites can offer better structural performance but the average modeler does not have the experience of working with them. Also drives the cost up which is not the desired intent of Got Gas RC.

Weldbond is far superior both in strength, flexibility of the finished product and for putting a super finish on the model.

Weldbond is the only glue that allows me to wet sand the dried glue to a glass finish.


I trust you water down your white glue. When I used Elmers I would water down at least 50 percent to reduce the final weight.

I stopped using Elmers 20 years ago as it was not nearly as good Weldbond.
Weldbond is a white glue but it is a variant on the Aliphatic Glues. There is a web site that reviews every glue that was ever produced.

You are using a lot of glue! :)

I use Elmers straight out of the bottle and squeege it on the paper. Finish is smooth paper but cover with monokote anyway. Hardest thing with this technique is working fast enough to do both sides of a wing panel so that everything can dry and tighten up at the same time while seated in the core beds. Believe me, the paper does tighten up.

Prior to gluing the paper on try wetting the paper then use watered down glue. You won't have to rush as much. When the glue and paper dry the shrinkage of the paper creates a smooth drum tight skin. The shrunk paper provides torsional rigidity while your spar caps provide bending strength.
